NLE Perioperative & Pain Nursing — Postoperative Care and Surgical Wound ManagementMisconception Buster
Avoid the most common Postoperative Care and Surgical Wound Management mistakes made by NLE reviewers. Each misconception here has been pulled from real NLE Perioperative & Pain Nursing questions where Professional Regulation Commission (PRC) — Board of Nursing used it to separate strong reviewers from weak ones. Learn these before your next mock.
Exam context
Professional Regulation Commission (PRC) — Board of Nursing runs the Philippine Nurse Licensure Examination (PNLE) on Bi-annual. Its Perioperative & Pain Nursing section sits under a "Core" weighting, and Postoperative Care and Surgical Wound Management is the 2nd chapter in the 3-chapter NLE Perioperative & Pain Nursing rotation. The NLE passing mark is 75% weighted average with no sub-test below 60%, and the most recent 2026 paper drew about 50 questions from Perioperative & Pain Nursing.
Postoperative Care and Surgical Wound Management - Misconception Buster
Many NLE failures in the Perioperative and Pain Nursing section are not caused by a lack of knowledge — they are caused by holding a small number of firmly wrong beliefs that produce consistently wrong answers. In postoperative nursing, the stakes are highest: a wrong priority, a wrong action during an evisceration, or a wrong understanding of wound healing can cost you multiple questions in a single exam. This guide identifies the 10 most dangerous misconceptions Filipino nursing students carry into the NLE, explains WHY the wrong belief feels logical, delivers the TRUTH with clinical evidence, and then tests your thinking with a TRAP QUESTION — the kind the PRC Board of Nursing uses to separate test-takers who truly understand from those who merely memorized. Study these corrections before your review notes; correcting a wrong belief is more powerful than memorizing a new fact.
Summary
The most dangerous misconceptions in postoperative nursing share a common thread — they feel logical but are clinically opposite to the correct action. Here are the key takeaways to protect your NLE score: (1) NEVER push eviscerated organs back — always cover with sterile saline-moistened gauze and notify the surgeon; (2) In the PACU, AIRWAY comes first — always apply ABCs before assessing pain or blood pressure; (3) NEVER massage a suspected DVT — it can cause fatal pulmonary embolism; (4) Early postoperative fever (Day 1) is ATELECTASIS, not infection — treat with deep breathing, not antibiotics; (5) Jackson-Pratt and Hemovac drains MUST be recompressed after emptying to restore suction; (6) Wound dehiscence/evisceration peaks at postoperative DAYS 5–7, not day 1 — recognize the warning signs (serosanguineous drainage, 'popping' sensation); (7) Early ambulation is a powerhouse intervention — it prevents atelectasis, DVT, AND paralytic ileus simultaneously; (8) Urinary retention threshold is 6–8 hours, not 4 hours — use non-invasive measures first; (9) Secondary intention healing is intentional and correct for contaminated wounds — it is not a complication; (10) Hyperglycemia and malnutrition are the most critical modifiable factors impairing wound healing, especially in Filipino patients with diabetes. Review these corrections until each one feels more natural than the intuitive but wrong alternative — that is the mark of genuine clinical understanding and NLE readiness.

Wound Dehiscence and Evisceration — Emergency Management
Severity
critical
Exam Impact
A question on evisceration management will almost certainly appear. Students who hold this misconception choose the 'reduce the organs' option and lose the question entirely. They may also lose a related question about positioning or dressing type.
The Reality
Attempting to replace (reduce) the eviscerated organs is absolutely contraindicated and can cause serious harm — it can introduce infection deep into the peritoneal cavity, traumatize or tear the intestine, and cause vascular compromise. The correct emergency action is to COVER the organs with a sterile dressing moistened with sterile normal saline (NSS) to maintain moisture and prevent drying and infection, then notify the surgeon immediately. The patient is positioned in low Fowler's with knees flexed to reduce abdominal tension. Only the surgeon returns organs to the cavity — in the operating room, under sterile conditions. This is a patient-safety-critical protocol and is one of the most frequently tested NLE items in perioperative nursing.
Trap Question
Question
A patient who had an appendectomy 6 days ago suddenly reports a 'popping' sensation followed by a gush of pink drainage. The nurse assesses the wound and finds loops of intestine protruding through the incision. What is the FIRST nursing action?
Explanation
The first action is to cover and protect the viscera with sterile saline-moistened gauze — NOT to reposition them. Reducing the organs is contraindicated because it risks introducing infection into the peritoneum and traumatizing the bowel. The surgeon must manage the return of organs in the OR. Staying with the patient addresses safety (Maslow's physiological and safety needs), and the moist gauze prevents desiccation and further tissue damage. Low Fowler's with flexed knees reduces abdominal wall tension while waiting for the surgical team.
Wrong Answer
Gently reposition the intestinal loops back into the abdominal cavity and apply a sterile dressing to prevent further contamination.
Correct Answer
Stay with the patient, call for help, and cover the protruding intestines with a sterile gauze soaked in sterile normal saline while notifying the surgeon immediately.
Misconception Id
M1
Correct Vs Incorrect
Correct Approach
Student recognizes evisceration as a surgical emergency and chooses: 'Cover the protruding organs with a sterile gauze moistened with sterile normal saline, position in low Fowler's with knees flexed, and notify the surgeon immediately. Do NOT push the organs back in.'
Incorrect Approach
Student sees 'evisceration' in a question and chooses: 'Apply gentle pressure to push the organs back in and cover with a dry sterile dressing.' Reasoning: reducing exposure prevents infection.
Why Students Believe It
Students reason that exposed organs are at high risk for contamination and drying, so 'returning them to where they belong' feels like the logical, protective action. The instinct to reduce exposure drives this wrong belief. Some students also confuse evisceration management with the first aid instinct to 'reduce' a protruding part.
In the PACU, the priority assessment after surgery is to check the patient's pain level and blood pressure first because pain control and hemodynamic stability are the most urgent postoperative concerns.

Immediate Postoperative Care — PACU Priorities
Severity
critical
Exam Impact
PACU priority questions are among the most common NLE perioperative items. Choosing 'pain' or 'blood pressure' as the first priority costs a mark every time. Questions often list four interventions and ask 'which should the nurse do FIRST.'
The Reality
The PACU priority always follows the ABCs — Airway, Breathing, Circulation — in that exact order. Airway and Breathing take absolute precedence because anesthesia-related airway obstruction (from tongue falling back, retained secretions, laryngospasm) and respiratory depression are the most immediately life-threatening complications. A patient with uncontrolled pain is distressed but alive; a patient with an obstructed airway can die within minutes. Assess the airway FIRST, then breathing (rate, depth, SpO2), then circulation (BP, HR, skin color). Pain is addressed only after A, B, and C are confirmed safe. In the NLE nursing process, Maslow's hierarchy places physiological survival needs — breathing — above comfort needs — pain.
Trap Question
Question
A patient returns to the PACU after a 3-hour laparotomy under general anesthesia. The patient is drowsy but arousable. The nurse notes the surgical dressing is dry and intact. What should the nurse assess FIRST?
Explanation
The ABCs dictate that Airway and Breathing are always assessed first. General anesthesia causes residual muscle relaxation and CNS depression, making airway obstruction (from the tongue falling back) and respiratory depression the most immediate threats to life. The dressing is already noted to be dry and intact, which provides some initial reassurance about hemorrhage. Blood pressure is a Circulation (C) concern — important, but assessed after A and B are confirmed. Under Maslow's hierarchy, oxygenation (physiological survival) precedes all other assessments.
Wrong Answer
Blood pressure and heart rate, because hemodynamic instability is the greatest risk after major abdominal surgery.
Correct Answer
Airway patency and adequacy of breathing — assess rate, depth, and oxygen saturation first.
Misconception Id
M2
Correct Vs Incorrect
Correct Approach
Student applies ABCs and Maslow's hierarchy: 'Assess the airway for patency and ensure adequate breathing FIRST, then assess circulation, then assess pain.' Airway is the top priority because respiratory depression is the most immediate life-threatening risk post-anesthesia.
Incorrect Approach
Student reads 'PACU assessment' and selects: 'Assess the patient's pain level using a numeric rating scale' as the first priority because pain is a vital sign and a nursing obligation.
Why Students Believe It
Pain management is heavily emphasized in nursing school and is part of the nursing mandate under RA 9173. Blood pressure monitoring is a core vital sign. Students often associate 'postoperative' with pain and 'hemodynamic' with blood pressure, leading them to rank these ahead of airway. Additionally, many clinical experiences focus on pain scoring before other assessments.
Early ambulation should be avoided or delayed after surgery because it risks wound dehiscence and excessive pain, and the patient needs rest to heal.

Postoperative Complications — Paralytic Ileus, DVT, Atelectasis Prevention
Severity
major
Exam Impact
Any question asking 'which nursing measure prevents the most postoperative complications' or asking about paralytic ileus, atelectasis, or DVT management will include early ambulation as the correct answer. Students who fear ambulation will avoid these options.
The Reality
Early ambulation is one of the most powerful postoperative nursing interventions. It prevents MULTIPLE complications simultaneously: it reduces venous stasis (preventing DVT), improves respiratory function (preventing atelectasis and pneumonia by promoting full lung expansion), stimulates peristalsis (preventing paralytic ileus), prevents pressure injuries, and improves overall circulation and wound healing. The risk of wound separation from ambulation with a properly sutured wound is negligible when the patient is supported. The NANDA nursing diagnoses that drive early ambulation include Risk for Impaired Gas Exchange, Risk for Peripheral Tissue Perfusion (DVT), and Constipation (ileus). RA 9173 places independent nursing measures like early ambulation within the nurse's scope of practice and professional responsibility.
Trap Question
Question
A patient on postoperative day 1 following a colostomy has absent bowel sounds, mild abdominal distention, and no passage of flatus. The physician's orders include ambulation BID. The patient reports pain of 6/10 and asks to stay in bed. Which nursing action is MOST appropriate?
Explanation
Paralytic ileus following abdominal surgery is best managed with early ambulation, which stimulates peristalsis. Pain is a barrier but not a contraindication — the nurse pre-medicates with analgesics and supports the patient during ambulation. Keeping the patient in bed prolongs ileus. This also addresses DVT and atelectasis risk simultaneously. The nurse acts within RA 9173 scope, implementing the physician's order and using independent nursing measures to promote recovery.
Wrong Answer
Allow the patient to remain in bed because pain of 6/10 indicates that ambulation would be harmful and could worsen the abdominal distention.
Correct Answer
Administer the prescribed analgesic, allow it time to take effect, then assist the patient to ambulate as ordered, explaining that walking promotes the return of bowel function.
Misconception Id
M3
Correct Vs Incorrect
Correct Approach
Student recognizes that early ambulation (as early as the day of surgery or postoperative day 1, with physician order and patient support) prevents atelectasis, DVT, and paralytic ileus simultaneously. Pain is managed before ambulation with analgesics, and the patient is supported.
Incorrect Approach
Student advises the patient to 'remain in bed for the first 48 hours and rest to promote wound healing and avoid pain.' They choose positioning and breathing exercises over actual ambulation.
Why Students Believe It
'Rest promotes healing' is a deeply ingrained lay belief, and students worry that activity will put tension on the suture line. Pain during movement reinforces the instinct to keep the patient still. Some clinical settings that prioritize pain avoidance may inadvertently delay ambulation.

Deep Vein Thrombosis — Prevention and Management
Severity
critical
Exam Impact
DVT management questions always include 'massage the calf' as a distractor option. Students who hold this misconception choose it and lose the mark. PE-related questions also test the understanding that massaging a DVT causes embolism.
The Reality
Massaging a limb with suspected DVT is absolutely contraindicated and is potentially fatal. A DVT clot can be dislodged by mechanical pressure, travel through the venous system to the right heart, and lodge in the pulmonary vasculature — causing a pulmonary embolism (PE), which is a life-threatening emergency. Signs of DVT (Homans' sign: calf pain on dorsiflexion, though this is not specific) include unilateral calf pain, swelling, warmth, and redness. The correct management is to rest the limb, elevate it if ordered, notify the physician, and prepare for diagnostic evaluation (Doppler ultrasound) and anticoagulation therapy (e.g., enoxaparin/LMWH).
Trap Question
Question
A patient on postoperative day 4 after a total hip replacement reports right calf pain and you notice mild swelling and warmth compared to the left leg. Which nursing action is CONTRAINDICATED?
Explanation
The presentation is classic for DVT — unilateral calf pain, swelling, and warmth on postoperative day 4 (the 'W for Walking/Veins' in the 5 Ws fever timeline). Massaging the affected limb risks dislodging the thrombus and causing a pulmonary embolism. The correct actions are complete rest of the limb, elevation if ordered, physician notification, Doppler ultrasound, and anticoagulation (e.g., LMWH such as enoxaparin). Prevention strategies — sequential compression devices, leg exercises, early ambulation, and prophylactic anticoagulants — should have been initiated preoperatively and maintained postoperatively.
Wrong Answer
Massage the right calf to improve venous circulation and reduce swelling.
Correct Answer
Massaging the calf is contraindicated. The nurse should rest the limb, avoid massage, notify the physician, and prepare for diagnostic workup and anticoagulation.
Misconception Id
M4
Correct Vs Incorrect
Correct Approach
Student recognizes DVT signs, immediately stops any leg manipulation, rests and elevates the limb, notifies the physician, avoids leg exercises on the affected side, and prepares for Doppler ultrasound and anticoagulation orders.
Incorrect Approach
Patient reports right calf pain on postoperative day 4. Student charts: 'Provided calf massage to improve circulation and reduce discomfort.' They select 'massage the affected leg' in the exam.
Why Students Believe It
Massage promotes circulation — this is a well-known nursing measure used in many other contexts (e.g., preventing pressure injuries, relieving muscle cramps). Students apply the same logic to DVT, reasoning that improving blood flow will dissolve the clot.

Postoperative Fever Timeline — The 5 Ws
Severity
major
Exam Impact
The NLE frequently gives a scenario with a specific postoperative day and a fever, then asks the nurse to identify the most likely cause. Students who default to 'infection' for all postoperative fevers get these questions wrong consistently.
The Reality
Fever in the first 24 hours after surgery is almost always caused by ATELECTASIS (the '5 Ws' — Wind), not infection. Shallow breathing under anesthesia and postoperative pain causes alveolar collapse, which triggers a low-grade inflammatory response. Surgical site infection (SSI) typically does NOT manifest until postoperative days 4–6 — it takes time for bacteria to multiply to levels that produce systemic fever. The 5 Ws timeline is: Day 1 = Wind (atelectasis); Days 2–3 = Water (UTI); Days 3–5 = Walking/Veins (DVT); Days 4–6 = Wound (SSI); any time = Wonder drugs (drug reactions). Knowing this timeline is essential for correctly identifying the cause of fever at any given postoperative day.
Trap Question
Question
A patient who had an open cholecystectomy 18 hours ago has a temperature of 38.3°C. Breath sounds are slightly diminished at the bases bilaterally. What is the MOST likely cause of this fever?
Explanation
Eighteen hours is still within the first postoperative day ('Wind' in the 5 Ws mnemonic). Diminished basilar breath sounds are a classic finding of atelectasis. SSI does not present until days 4–6 because it requires sufficient bacterial proliferation time. The correct nursing management is to promote lung expansion: deep breathing exercises, incentive spirometry, coughing (with pillow splinting), hydration, and early ambulation — not wound care or antibiotics.
Wrong Answer
Surgical site infection from contamination during the cholecystectomy procedure.
Correct Answer
Atelectasis — alveolar collapse from shallow breathing in the immediate postoperative period.
Misconception Id
M5
Correct Vs Incorrect
Correct Approach
Student applies the 5 Ws: 12 hours = Day 1 = Wind = Atelectasis. The nurse assesses breath sounds, encourages deep breathing and incentive spirometry, and ambulates the patient. A wound culture is not indicated at this point.
Incorrect Approach
Patient has a temperature of 38.2°C 12 hours after cholecystectomy. Student thinks: 'Fever = infection. The wound must be infected. Prepare to collect a wound culture.' They select 'surgical site infection' as the most likely cause.
Why Students Believe It
The word 'infection' is closely associated with 'fever' in basic nursing education. Since the patient just had surgery, students logically (but wrongly) assume any fever is from wound contamination during the procedure.

Surgical Drains — Closed Suction Drain Care
Severity
major
Exam Impact
Questions about drain care ask what the nurse does AFTER emptying a JP or Hemovac. Students who do not know about recompression select incomplete or wrong answers.
The Reality
Jackson-Pratt (JP) and Hemovac drains are CLOSED ACTIVE SUCTION systems. They function by maintaining a compressed (collapsed) state that creates gentle negative pressure, which draws fluid from the surgical site. After emptying and measuring the output, the nurse MUST re-compress (re-squeeze) the reservoir and then close the drainage port to re-establish suction. If left uncompressed and open, no suction is generated and fluid accumulates at the surgical site, increasing the risk of seroma, hematoma, and infection. A Penrose drain is a passive open drain — it drains by gravity and capillary action and does not require compression. The nurse must distinguish between drain types and know their respective care.
Trap Question
Question
The nurse empties a Jackson-Pratt drain that has collected 45 mL of serosanguineous drainage since the last emptying 8 hours ago. After recording the output, what is the NEXT appropriate action?
Explanation
The JP drain works by sustained negative pressure created by the compressed bulb. After emptying, the nurse must re-compress the bulb and close it before reattachment — otherwise no suction exists and the drain becomes non-functional, allowing fluid to pool. Failure to recompress is a common clinical error. The color (serosanguineous — pink, mixed blood and serum) is expected in early postoperative days and should be documented. A sudden change to bright red (hemorrhage) or foul purulent drainage (infection) requires physician notification.
Wrong Answer
Reattach the drain tubing to the patient's gown and document the output — the drain will continue to collect fluid as it fills.
Correct Answer
Compress the bulb reservoir completely, close the drainage port to maintain suction, and then re-secure the drain before documenting.
Misconception Id
M6
Correct Vs Incorrect
Correct Approach
Nurse empties the JP drain, records 30 mL of serosanguineous drainage, then COMPRESSES the reservoir fully (squeezes the bulb flat), closes the drainage port while maintaining compression, and re-secures the drain. This re-establishes the negative suction pressure.
Incorrect Approach
Nurse empties the JP drain reservoir, notes and records 30 mL of serosanguineous drainage, then hangs the drain back without compressing it. Reasoning: 'The fluid will drain on its own since the reservoir is now empty.'
Why Students Believe It
Students may not fully understand the mechanism of closed-suction drains. They know drains drain fluid but think the system is like a regular passive drain or that negative pressure is self-sustaining after emptying.

Wound Healing — Types of Intention
Severity
minor
Exam Impact
Questions describe a wound type (contaminated, infected, large) and ask which type of healing will occur. Students who think primary is always best may incorrectly choose it for contaminated wounds.
The Reality
Secondary intention healing (leaving the wound open to heal by granulation from the base upward) is the CORRECT and INTENTIONAL method for contaminated, infected, or large wounds where primary closure would trap bacteria and cause a severe infection or abscess. Examples include infected diabetic foot wounds, pilonidal abscesses drained open, and bite wounds. Tertiary (delayed primary) intention combines both: the wound is left open initially to allow infection control and granulation, and then surgically closed later when conditions are safe. Each healing intention is the appropriate choice for specific clinical situations — there is no universally 'best' method. The nurse must understand which wound type requires which healing approach to plan appropriate wound care.
Trap Question
Question
A patient with a perforated appendix underwent emergency appendectomy. The surgeon left the skin incision open and packed it with sterile gauze instead of suturing it closed. What type of wound healing is expected?
Explanation
A perforated appendix releases fecal material into the peritoneum and surgical field, making the wound highly contaminated. Closing it primarily would trap bacteria and cause a serious wound infection or abscess. Secondary intention — allowing the wound to fill in from the bottom with granulation tissue — is the intentional and correct clinical decision. It results in a larger scar and slower healing, but avoids life-threatening infection. The nurse's role includes wound packing changes using aseptic technique, monitoring for granulation, and educating the patient about the expected healing timeline.
Wrong Answer
Primary intention — the wound will heal rapidly because it is a surgical incision.
Correct Answer
Secondary intention — the wound heals by granulation from the base upward because it is contaminated and cannot be safely sutured closed.
Misconception Id
M7
Correct Vs Incorrect
Correct Approach
Student recognizes that secondary intention is intentionally used for contaminated, infected, or large wounds to prevent abscess formation, and primary intention is used for clean, approximated surgical incisions. They correctly identify the healing type based on the clinical description.
Incorrect Approach
Student reads about an infected abdominal wound that was left open and thinks: 'This is an error — the wound should be closed primarily. Secondary intention is a complication, not a plan.' They select 'primary intention' as the correct healing approach for a contaminated wound.
Why Students Believe It
Students associate 'closed wounds' with 'healed wounds.' The idea that leaving a wound open could be a therapeutic choice is counterintuitive. Suturing seems like the definitive, superior treatment.

Postoperative Urinary Retention — Assessment and Management
Severity
major
Exam Impact
Questions about urinary retention management will ask about the correct timeline AND the correct sequence of interventions (non-invasive first, then invasive). Students who catheterize at 4 hours get both the timing and the sequence wrong.
The Reality
The standard clinical threshold for postoperative urinary retention is the inability to void within 6–8 hours after surgery. Earlier intervention thresholds exist only when the patient reports significant discomfort or the bladder scan (bladder ultrasound) shows a distended bladder holding a large volume (typically 300–400 mL or as per facility protocol). The nurse's role is to first use non-invasive measures: ensure privacy and a quiet environment, help the patient to an upright position if allowed, run water near the patient, apply a warm compress to the suprapubic area, and encourage relaxation. Catheterization is ordered by the physician and performed only when non-invasive measures fail and clinical criteria are met. Premature catheterization increases the risk of UTI.
Trap Question
Question
A patient who had a spinal anesthesia for a knee surgery 5 hours ago has not yet voided. The patient denies lower abdominal discomfort. The bladder scan shows 180 mL. What is the MOST appropriate nursing action?
Explanation
The standard postoperative retention threshold is 6–8 hours, and a bladder scan of 180 mL with no discomfort does not indicate significant retention. Spinal anesthesia affects bladder function longer than general anesthesia, which is expected. Non-invasive nursing measures are the first line. Catheterization is reserved for when the 6–8 hour threshold is exceeded with a significantly distended bladder (typically 300–400+ mL), significant discomfort, or physician order. Premature catheterization introduces catheter-associated UTI risk — a preventable hospital-acquired infection.
Wrong Answer
Perform urinary catheterization immediately because 5 hours without voiding indicates urinary retention.
Correct Answer
Continue to monitor, apply non-invasive measures to encourage voiding (privacy, upright position, running water), and reassess — the 5-hour threshold with no discomfort and only 180 mL on scan does not yet meet catheterization criteria.
Misconception Id
M8
Correct Vs Incorrect
Correct Approach
Patient has not voided 5 hours after surgery; the nurse assesses for bladder distention via bladder scan or palpation, applies non-invasive measures (privacy, warm water sounds, warm compress, upright positioning), and reports to the physician if the patient still cannot void by the 6–8 hour threshold or if the bladder scan shows significant retention with discomfort.
Incorrect Approach
Patient has not voided 4 hours after surgery. Student immediately prepares urinary catheterization equipment, reasoning that 4 hours without voiding confirms retention and catheterization is needed.
Why Students Believe It
Students learn that 'normal' voiding occurs every 3–4 hours and that retention is a concern postoperatively. The 4-hour figure is close to this teaching and feels like a logical cutoff. The urgency to intervene also feels appropriate.

Wound Dehiscence and Evisceration — Timing and Recognition
Severity
major
Exam Impact
NLE scenario questions often specify the postoperative day to guide the student to the correct complication. A student who doesn't know the day 5–7 window will miss the diagnostic clue and choose the wrong complication or the wrong priority action.
The Reality
Wound dehiscence and evisceration most commonly occur around postoperative days 5–7, specifically because this is the period when the initial clot and early granulation have not yet been reinforced by new collagen (the proliferative phase begins around day 4–5 but the wound is still mechanically weak). During this vulnerable window, increased intra-abdominal pressure from coughing, straining, vomiting, or sneezing can split the wound edges apart. Risk factors include obesity, malnutrition, infection, poor glycemic control in diabetics, chronic steroid use, and repeated vomiting. The classic warning sign is a sudden gush of serosanguineous (pink) drainage from the wound, often with a patient report of a 'giving way,' 'popping,' or 'tearing' sensation.
Trap Question
Question
An obese patient who had an exploratory laparotomy 6 days ago calls the nurse and reports 'feeling like something is giving way' in the abdomen. On assessment, you note a large amount of pink, watery drainage soaking the dressing. What complication do you FIRST suspect?
Explanation
The combination of: (1) postoperative day 5–7 window, (2) risk factor of obesity, (3) serosanguineous (not purulent) drainage, and (4) the subjective report of 'giving way' is the classic presentation of wound dehiscence with possible evisceration. Infection produces purulent (thick, yellow-green, foul-smelling) drainage and develops with fever. The nurse must immediately expose and assess the wound to determine if dehiscence alone has occurred or if evisceration is present, then institute the appropriate emergency management protocol.
Wrong Answer
Surgical site infection — purulent drainage and fever are expected at postoperative day 6.
Correct Answer
Wound dehiscence or evisceration — the serosanguineous drainage, 'giving way' sensation, obesity, and postoperative day 6 are classic indicators.
Misconception Id
M9
Correct Vs Incorrect
Correct Approach
Student recognizes: Day 6 + sudden serosanguineous drainage + 'popping' sensation = high alert for dehiscence or evisceration. The nurse immediately assesses the wound, calls for help, and prepares for emergency management if viscera are visible.
Incorrect Approach
Student reads 'postoperative day 6, sudden gush of pink drainage' and thinks of wound infection (because infection is always associated with drainage) rather than dehiscence/evisceration.
Why Students Believe It
Students understand that wound complications can theoretically occur at any time. Without a specific timeline memorized, they apply this vague understanding to all wound-related questions.

Atelectasis — Prevention and Nursing Management
Severity
major
Exam Impact
Questions ask what the nurse does to PREVENT pulmonary complications. Students who view atelectasis as minor may choose less active interventions (e.g., just supplemental oxygen) rather than the complete nursing protocol.
The Reality
Atelectasis is the MOST COMMON postoperative pulmonary complication and is both preventable and treatable — but only with ACTIVE, aggressive nursing intervention. If retained secretions and collapsed alveoli are not addressed within the first 24–48 hours, the warm, moist, stagnant environment in the collapsed airways becomes an ideal culture medium for bacterial growth, and pneumonia follows. In elderly, immunocompromised, or diabetic patients (common in Philippine hospital settings), postoperative pneumonia carries a significant mortality risk. The nursing interventions — deep breathing, incentive spirometry (10 breaths every hour), coughing with pillow splinting, early ambulation, adequate hydration, and frequent repositioning — are the highest-yield, evidence-based measures in postoperative pulmonary care and must be initiated proactively, not reactively.
Trap Question
Question
A 58-year-old patient on postoperative day 1 after a colon resection has a temperature of 38.1°C and decreased breath sounds at both lung bases. The patient is breathing at a rate of 18/min with SpO2 of 95% on room air. What is the PRIORITY nursing intervention?
Explanation
Day 1, low-grade fever, diminished basilar breath sounds, and SpO2 of 95% are classic atelectasis. Supplemental oxygen addresses hypoxia symptomatically but does NOT treat the underlying cause (alveolar collapse from retained secretions and shallow breathing). The priority is to RE-EXPAND the alveoli through active nursing measures — deep breathing, incentive spirometry, coughing, and ambulation. These are independent nursing interventions within the nurse's scope under RA 9173. If left untreated, this progresses to pneumonia. The nurse should also document and report the findings to the physician.
Wrong Answer
Apply supplemental oxygen via nasal cannula and continue to monitor the patient — the fever and diminished sounds are expected and will resolve spontaneously.
Correct Answer
Encourage deep breathing exercises and use of incentive spirometry immediately; teach splinted coughing; assist the patient to ambulate or at minimum to sit up; ensure adequate hydration — these are the priority interventions to re-expand collapsed alveoli and prevent progression to pneumonia.
Misconception Id
M10
Correct Vs Incorrect
Correct Approach
Student immediately initiates the pulmonary care protocol: encourages deep breathing exercises every 1–2 hours, demonstrates and supervises incentive spirometry (10 breaths every waking hour), teaches splinted coughing, increases ambulation, ensures adequate hydration, and reports persistent fever or worsening breath sounds to the physician.
Incorrect Approach
Patient on postoperative day 1 has a low-grade fever (37.9°C) and slightly diminished breath sounds at the bases. Student thinks: 'This is normal — atelectasis will clear as the patient breathes more. Give oxygen and observe.'
Why Students Believe It
Atelectasis sounds like a 'small' lung problem compared to pneumonia or PE. Students may have learned about it as a possible but manageable finding and underestimate how rapidly it can progress to pneumonia, respiratory failure, or sepsis if untreated.

PACU — Aldrete Score and Discharge Criteria
Severity
minor
Exam Impact
Questions may ask which parameter is included in the Aldrete score, or present a scenario and ask whether the patient meets PACU discharge criteria based on the score. Confusing Aldrete components leads to wrong answers.
The Reality
The Aldrete score (also called the Post-Anesthesia Recovery Score) assesses FIVE physiological parameters for safe PACU discharge: (1) Activity — ability to move limbs on command; (2) Respiration — adequacy of breathing; (3) Circulation — blood pressure stability relative to baseline; (4) Consciousness — level of alertness; (5) Oxygen saturation — SpO2 on room air or with supplemental oxygen. Each parameter is scored 0–2, for a maximum score of 10. A score of 9–10 typically indicates readiness for transfer. Pain and oral intake are assessed separately and are NOT part of the Aldrete score. The Aldrete score specifically measures recovery from anesthesia, not overall postoperative wellness.
Trap Question
Question
Which of the following is a component of the Aldrete Post-Anesthesia Recovery Score used to determine readiness for PACU discharge?
Explanation
The Aldrete score assesses: Activity, Respiration, Circulation, Consciousness, and O2 Saturation — the five parameters most critical for safe post-anesthesia recovery. Pain is managed separately (often using a numeric rating scale) but is not a scored Aldrete parameter. Oral intake is also not part of the score. A score of 9–10 out of 10 indicates the patient has adequately recovered from anesthesia and can be safely transferred to the ward or discharged home (for ambulatory surgery).
Wrong Answer
Pain rating scale score of 4 or less.
Correct Answer
Oxygen saturation — ability to maintain SpO2 on room air or with minimal supplemental oxygen.

Correct Vs Incorrect
Correct Approach
Student correctly lists the 5 Aldrete parameters: Activity, Respiration, Circulation, Consciousness, and Oxygen saturation — all related to physiological recovery from anesthesia, not pain or diet readiness.
Incorrect Approach
Student is asked which parameters are included in the Aldrete score and selects 'pain rating and tolerance of oral fluids' because these are key postoperative assessments they associate with PACU readiness.
Why Students Believe It
Students know the Aldrete score is used in the PACU for discharge readiness but may not have memorized its specific parameters. Pain and oral intake are major postoperative concerns, so students assume these are what the score measures.
Vitamin C and zinc supplements after surgery are optional 'extras' that do not significantly affect wound healing — the primary determinants are the surgeon's technique and the patient's age.

Topic
Wound Healing — Nutritional and Metabolic Factors
Severity
minor
Exam Impact
Questions about factors impairing wound healing or nursing interventions to promote healing may include nutrition. Students who dismiss nutrition as minor may miss these points.
The Reality
Nutrition is a PRIMARY determinant of wound healing and is within the nurse's scope of assessment and patient education. Protein is essential for tissue rebuilding and immune function. Vitamin C (ascorbic acid) is required for collagen synthesis — without it, the wound cannot progress through the proliferative phase and the scar remains weak. Zinc is essential for cell proliferation and enzyme activity in wound repair. Glycemic control in diabetic patients is equally critical — hyperglycemia impairs neutrophil function (increasing infection risk), reduces collagen deposition, and delays all phases of healing. The nurse assesses nutritional status, refers to a dietitian as needed, monitors for malnutrition (low albumin, weight loss), and provides specific education on high-protein, high-vitamin C foods (common in Filipino diet: malunggay, citrus, kamote, fish, eggs). Under RA 9173, health education is a core nursing function.
Trap Question
Question
A 52-year-old patient with type 2 diabetes mellitus (fasting blood sugar 280 mg/dL) is on postoperative day 3 after an abdominal hysterectomy. The wound edges appear poorly approximated and the patient has low serum albumin. Which factor MOST significantly impairs this patient's wound healing?
Explanation
In a diabetic patient, hyperglycemia is the most significant modifiable factor impairing wound healing — it suppresses the immune response, reduces collagen crosslinking, and impairs the inflammatory and proliferative phases. Hypoalbuminemia indicates protein deficiency, which limits the raw material needed for tissue repair. The nurse's priorities include blood glucose monitoring and management, nutritional assessment, referral to a dietitian, and education on high-protein foods and wound care. Age and surgical technique are factors but are far less modifiable and less impactful than glycemic and nutritional status in this scenario.
Wrong Answer
The patient's age and the complexity of the hysterectomy procedure.
Correct Answer
Uncontrolled hyperglycemia (blood sugar 280 mg/dL) combined with hypoalbuminemia (malnutrition), which impairs collagen synthesis, neutrophil function, and cellular proliferation.
Misconception Id
M12
Correct Vs Incorrect
Correct Approach
Student correctly identifies that hyperglycemia impairs neutrophil function, reduces collagen synthesis, and delays all phases of wound healing in diabetic patients. The nurse ensures glycemic control, adequate protein and vitamin C intake, and wound monitoring.
Incorrect Approach
When asked 'which factor most impairs wound healing in a poorly controlled diabetic patient,' student selects 'age-related tissue fragility' instead of hyperglycemia and poor nutrition.
Why Students Believe It
Students focus on surgical technique and age as wound healing factors because these are frequently discussed. Nutritional factors are taught but often treated as secondary in nursing school review, leading to underestimation of their clinical importance.
Quick Self Check
Pushing back (reducing) the eviscerated organs is strictly contraindicated. The correct action is to cover the viscera with a sterile saline-moistened gauze, position the patient in low Fowler's with knees flexed, and notify the surgeon immediately. Only the surgeon may return organs to the abdominal cavity — in the OR.
Statement
During wound evisceration, the nurse should gently push the protruding organs back into the abdominal cavity to protect them from drying and infection.
The ABCs — Airway, Breathing, Circulation — dictate the order of assessment in any critically vulnerable patient. Post-anesthesia, the greatest immediate risks are airway obstruction and respiratory depression. Pain, blood pressure, and dressing checks come after A and B are confirmed safe.
Statement
The FIRST priority assessment for a patient arriving in the PACU after general anesthesia is ensuring airway patency and adequate breathing.
Calf massage is absolutely contraindicated when DVT is suspected. Mechanical pressure can dislodge the thrombus, leading to pulmonary embolism — a life-threatening emergency. The affected limb must be rested and immobilized. The physician is notified and anticoagulation therapy is initiated.
Statement
Massaging the calf of a patient with suspected DVT helps promote blood flow and can reduce the size of the clot.
The '5 Ws' mnemonic places Wind (atelectasis) as the cause of early postoperative fever (Day 1). Surgical site infection (Wound) does not typically produce fever until postoperative days 4–6, as it requires time for bacterial proliferation. Management of early fever focuses on pulmonary expansion, not antibiotics or wound cultures.
Statement
Fever occurring within the first 24 hours after surgery is most likely caused by atelectasis, not surgical site infection.
The JP drain functions by maintaining compressed negative pressure. Re-compressing the bulb and then closing the port re-establishes suction, which draws fluid from the surgical site. Failing to recompress renders the drain non-functional and allows fluid to accumulate, risking seroma or hematoma.
Statement
After emptying a Jackson-Pratt drain, the nurse must re-compress the bulb before closing the drainage port to restore suction.
The peak risk period for wound dehiscence and evisceration is postoperative days 5–7. This is when the initial clot has dissolved but new collagen (which provides wound tensile strength) is still insufficient. Increased intra-abdominal pressure from coughing, vomiting, or straining during this window is the typical precipitating event.
Statement
Wound dehiscence and evisceration are most likely to occur within the first 24 hours after surgery when the wound is weakest.
Early ambulation is a multi-system preventive intervention: it promotes full lung expansion (preventing atelectasis), reduces venous stasis (preventing DVT), and stimulates peristalsis (preventing paralytic ileus). It is one of the highest-yield independent nursing actions in postoperative care and is within the nurse's scope under RA 9173.
Statement
Early ambulation after surgery is beneficial because it simultaneously helps prevent atelectasis, DVT, and paralytic ileus.
The clinical threshold for postoperative urinary retention is 6–8 hours without voiding, not 4 hours. The nurse first applies non-invasive measures — privacy, upright positioning, running water sounds, warm compress — and performs a bladder scan to assess residual volume. Catheterization is a physician-ordered invasive intervention used when non-invasive measures fail and clinical criteria are met, to avoid introducing catheter-associated urinary tract infection.
Statement
A patient who has not voided 4 hours after surgery should be catheterized immediately to prevent bladder injury from urinary retention.
