Examiner Tip

NLE examiners specifically test whether you can pair a fracture type with its primary complication. For open fractures, infection/osteomyelitis is the non-negotiable answer. If the question asks you to prioritize nursing care for an open fracture, cover with a sterile dressing is always correct before transport.

Model Answer

An open (compound) fracture is a fracture in which the broken bone penetrates through the skin, creating an external wound. Its key clinical significance is a high risk for infection and osteomyelitis, because the fracture site is exposed to external contaminants.

The NLE frequently presents a scenario where a basketball player 'rolls his ankle.' The expected answer recognizes this as a sprain (ligament) and prescribes RICE. A common distractor will say 'apply heat immediately' — this is WRONG for the first 24–48 hours. Heat is applied after 48 hours.

Model Answer

A sprain is a stretch or tear of a ligament (bone-to-bone connection), while a strain is a stretch or tear of a muscle or tendon. Both injuries are initially managed with RICE therapy: Rest, Ice application for the first 24–48 hours to reduce swelling, Compression with an elastic bandage, and Elevation of the affected extremity above heart level.

Stages of Bone Healing

Difficulty

Examiner Tip

Remember the mnemonic: 'Healing Fractures Become Ossified, Really' — Hematoma, Fibrocartilage, Bony callus, Ossification, Remodeling. The NLE may ask which stage occurs 'within the first 72 hours' (hematoma) or which stage involves osteoclasts (remodeling). Know the cells and timeframes, not just the names.

Model Answer

The five stages of bone healing in correct sequence are: (1) Hematoma formation — bleeding at the fracture site creates a clot within the first 1–3 days. (2) Fibrocartilage (soft callus) formation — fibroblasts lay down a fibrocartilaginous bridge within about one week. (3) Bony (hard) callus formation — osteoblasts convert the soft callus to woven bone over weeks 2–6. (4) Ossification — the callus matures into solid bone. (5) Remodeling — osteoblasts and osteoclasts reshape the bone along lines of stress, restoring original contour over months.

Fat Embolism Syndrome

Difficulty

Examiner Tip

FES vs. PE is a classic NLE trap. The differentiator is the PETECHIAL RASH and the post-long-bone fracture context with the 24–72 hour window. In FES, oxygen is ALWAYS the priority intervention. Always connect your clinical reasoning: 'Priority is oxygen because impaired gas exchange is the most immediate threat to life (Maslow: physiologic safety).'

Model Answer

The patient is manifesting fat embolism syndrome (FES), which is a complication of long-bone fractures that typically appears 24 to 72 hours after injury. The classic triad — hypoxemia (SpO2 88%, dyspnea), neurologic changes (restlessness, confusion), and petechial rash over the chest and axillae — confirms this diagnosis. The priority nursing intervention is the administration of supplemental oxygen to correct hypoxemia, as impaired gas exchange is the immediate life threat. The nurse must also notify the physician immediately and position the patient with the head of bed elevated to facilitate breathing.

Examiner Tip

For traction questions, examiners want to see that you understand WHY, not just WHAT. Always add a brief rationale ('...to prevent disruption of alignment,' '...to prevent osteomyelitis'). In the Philippine hospital setting, pin-site care is a delegated task that the nurse must perform with aseptic technique — referencing RA 9173 Sec. 28, nursing is accountable for safe care.

Model Answer

Three essential nursing responsibilities for a patient in skeletal traction are: (1) Ensure the weights hang freely at all times and never touch the floor, and that ropes remain on the pulleys — this maintains continuous, effective traction and prevents disruption of bone alignment. (2) Perform aseptic pin-site care (typically with normal saline or as ordered) at least once daily to prevent infection and osteomyelitis at the skeletal pin insertion sites. (3) Maintain countertraction by keeping the bed in the correct position and the patient's body as the counterforce — never remove or add traction weights without a physician's specific order, as this disrupts alignment and fracture healing.

When NLE items say 'which fracture type is common in children,' the answer is greenstick. When they say 'which fracture may suggest physical abuse,' think spiral fracture with inconsistent history. Knowing the clinical context for each fracture type prevents distractor traps.

Model Answer

A greenstick fracture is an incomplete fracture in which the bone bends and cracks on one side without breaking all the way through. It is most commonly seen in children, because their bones are more pliable and flexible compared to adult bones, allowing them to bend rather than completely break under stress.

Compartment Syndrome

Difficulty

hard

Template Id

T7

Examiner Tip

Compartment syndrome is the highest-stakes orthopedic topic in the NLE. The examiner wants three things: (1) correct identification, (2) naming pain on passive stretch as the earliest sign, and (3) knowing what NOT to do (no elevation, no ice). Memorize the rule: 'In compartment syndrome, standard swelling interventions KILL the limb.' Examiners have reported that elevation is the most common wrong answer chosen by NLE candidates.

Model Answer

The nurse should immediately suspect acute compartment syndrome. The hallmark signs present in this scenario are severe pain unrelieved by analgesia and pain that is WORSE on passive stretch (passive dorsiflexion of the toes) — this is the earliest and most reliable indicator of compartment syndrome. Pain on passive stretch is the critical distinguishing feature. Immediate nursing actions are: (1) Notify the physician immediately — compartment syndrome is a surgical emergency, as irreversible muscle and nerve damage occurs within 4 to 6 hours of sustained elevated compartment pressure. (2) Do NOT elevate the extremity above heart level and do NOT apply ice — both actions reduce arterial blood flow and worsen ischemia; maintain the limb at heart level. (3) Loosen or bivalve the cast as ordered to relieve external compressive pressure. (4) Prepare the patient for an emergency fasciotomy — surgical incision of the fascia to relieve compartment pressure. (5) Continue frequent neurovascular assessments (the 6 Ps: Pain, Pallor, Pulselessness, Paresthesia, Paralysis, Poikilothermia) and document findings.

NLE items about the 6 Ps often ask which P is 'earliest' or which P indicates irreversible damage. Pain on passive stretch = earliest. Pulselessness and Paralysis = latest/irreversible. Poikilothermia (coolness) is frequently omitted by students and may be the answer in a 'which of the following is a sign of compartment syndrome' item with Poikilothermia as the correct option.

Model Answer

The 6 Ps of compartment syndrome are: Pain (severe, unrelenting, disproportionate to injury, worsened by passive stretch), Pallor (pale skin over the affected area), Pulselessness (absent or diminished pulses), Paresthesia (numbness, tingling), Paralysis (inability to move), and Poikilothermia (coolness of the extremity). The earliest and most reliable sign is Pain — specifically pain on passive stretch of the digits, which appears before any other sign. The latest signs are Pulselessness and Paralysis, which indicate severe, often irreversible ischemic damage. Nursing assessment should never wait for pulselessness before acting.

NANDA nursing diagnoses for psychosocial responses to amputation always involve Disturbed Body Image (altered perception of own body) or Grieving (loss). The 3-part diagnostic statement (diagnosis + related to + as evidenced by) is mandatory for full marks. Always link your rationale to either therapeutic communication theory, Maslow's hierarchy, or RA 9173 professional nursing standards to elevate your answer.

Model Answer

The appropriate NANDA nursing diagnosis is: Disturbed Body Image related to loss of a body part (amputation) as evidenced by the patient's refusal to look at the residual limb and verbalization of feeling incomplete. Two priority nursing interventions with rationale are: (1) Encourage the patient to verbalize feelings about the amputation and the altered body image without judgment — rationale: creating a therapeutic, non-judgmental environment validates the patient's grief response, promotes emotional processing, and establishes trust, which is essential to effective nurse-patient therapeutic relationship as upheld by RA 9173 standards of nursing care. (2) Gradually involve the patient in residual limb care (such as dressing changes, stump wrapping, and skin inspection) and provide education about the rehabilitation process and prosthesis fitting — rationale: active participation in self-care promotes a sense of control and autonomy, shifts focus from loss to adaptation, and supports functional recovery, addressing the self-esteem and self-actualization levels of Maslow's hierarchy in preparation for reintegration.

Phantom Limb Pain

Difficulty

easy

Template Id

T10

Examiner Tip

The NLE has previously tested this concept with a question asking what the BEST nursing response is when an amputee says their missing foot hurts. Any answer that invalidates or dismisses the patient's pain is always WRONG. The therapeutic response is acknowledgment and validation. This also tests therapeutic communication, a core NCM 100 competency.

Model Answer

The patient is experiencing phantom limb pain — a real, physiologically-based phenomenon in which the patient perceives pain, burning, or other sensations in the amputated limb. The nurse should acknowledge and validate the patient's pain without dismissing it, stating clearly that phantom limb pain is a recognized, real physiologic experience, not imagined. The nurse should never say 'you cannot feel pain in a limb that is not there.' Management options include: pharmacologic approaches (analgesics, gabapentin or pregabalin for neuropathic pain, tricyclic antidepressants) and non-pharmacologic approaches such as mirror therapy, transcutaneous electrical nerve stimulation (TENS), and relaxation techniques.

Cast care discharge teaching is a high-frequency NLE topic under patient education (NCM 104). Examiners value specificity: instead of 'watch for pain,' write 'report increasing, unrelenting pain not relieved by analgesics.' The more specific your teaching point, the more it demonstrates safe, competent nursing care.

Model Answer

Four essential discharge teaching points for a patient with a short-arm cast are: (1) Never insert objects into the cast to scratch the skin underneath, as this can cause skin breakdown and infection. (2) Report immediately any increasing, unrelenting pain, numbness, tingling (paresthesia), pallor, or coolness of the fingers, as these are signs of neurovascular compromise or compartment syndrome. (3) Keep the cast dry; cover with a waterproof bag when bathing and do not use hair dryers on high heat to dry the cast, as this can burn the skin. (4) Elevate the arm above heart level for the first 24–48 hours to reduce edema and swelling, using pillows for support.

A 5-mark long answer requires five distinct, well-developed sections. Use numbered headings or bold labels for each section to make your answer easy to follow and mark. Examiners can award marks only for what they can clearly identify. The two most common errors in this question are: (1) prolonged elevation beyond 24 hours, and (2) dismissing phantom limb pain. Both are patient safety issues the NLE tests deliberately.

Model Answer

Nursing management of a patient after above-knee amputation in the immediate postoperative period involves five key domains: 1. HEMORRHAGE MONITORING AND PREVENTION: The nurse must monitor the residual limb dressing frequently for signs of bleeding — a small amount of serosanguineous drainage is expected, but heavy or bright red bleeding is abnormal and must be reported immediately. A tourniquet must be kept at the bedside at all times in the immediate postoperative period for emergency application if the stump bleeds massively. Vital signs are monitored for hypotension and tachycardia indicating hypovolemic shock. 2. POSITIONING TO PREVENT CONTRACTURES: In the first 24 hours, the residual limb is elevated on a pillow to reduce postoperative edema. However, AFTER the first 24 hours, prolonged elevation must be avoided because it promotes hip flexion contracture. The patient is positioned prone (face-down) for periods during the day to stretch the hip flexors and prevent flexion contracture, which would interfere with prosthesis fitting and ambulation. Pillows must NOT be placed under the knee or between the thighs for prolonged periods. 3. RESIDUAL LIMB (STUMP) CARE: The nurse inspects the residual limb for wound healing, signs of infection (redness, warmth, purulent discharge, fever), skin integrity, and edema. Stump wrapping with an elastic bandage (figure-8 technique) shapes and shrinks the stump in preparation for prosthesis fitting. The bandage is rewrapped every 4–6 hours or when loose, ensuring it is not too tight, which can impair circulation. 4. PAIN MANAGEMENT: Both incisional pain and phantom limb pain are assessed and managed. Phantom limb pain — the perception of pain in the amputated limb — is a real, physiologically based phenomenon and must be acknowledged and validated. Pharmacologic management includes analgesics, gabapentin or pregabalin for neuropathic pain, and adjunctive antidepressants. Non-pharmacologic options include mirror therapy and TENS. 5. PSYCHOSOCIAL SUPPORT: Amputation represents a significant loss — of body part, function, and body image. The nurse provides a therapeutic environment for the patient to express grief, maintains a non-judgmental attitude, involves the patient in care decisions, and coordinates with the rehabilitation team, social worker, and support groups for long-term reintegration and adaptation.

Fat Embolism Syndrome

Difficulty

Examiner Tip

For a 5-mark essay on FES, the examiner awards one mark per major concept area. Use a numbered heading structure so each mark-earning section is obvious. The 24–72 hour time frame and the petechial rash location (chest, axillae, conjunctivae) are the two facts that separate high-scoring from average answers. Always justify oxygen as priority using Maslow — this demonstrates clinical reasoning, not just memorization.

Model Answer

Fat Embolism Syndrome (FES) is a serious, potentially life-threatening complication of long bone and pelvic fractures. 1. PATHOPHYSIOLOGY: When a long bone (such as the femur, tibia, or humerus) or the pelvis is fractured, fat globules are released from the bone marrow into the systemic circulation. These fat emboli travel through the venous system and lodge in the pulmonary vasculature (causing acute respiratory failure), the cerebral vasculature (causing neurologic dysfunction), and the dermal capillaries (causing petechiae). FES typically manifests within 24 to 72 hours after the fracture injury — this time frame is a classic NLE discriminator. 2. CLASSIC MANIFESTATIONS — THE TRIAD: (a) Hypoxemia / Respiratory: dyspnea, tachypnea, decreased oxygen saturation (SpO2), use of accessory muscles — the most life-threatening feature. (b) Neurologic changes: restlessness, confusion, agitation, altered mental status, which may be mistaken for pain medication effects or anxiety. (c) Petechial rash: small, pinpoint hemorrhagic spots over the chest, neck, axillae, and conjunctivae — a pathognomonic (disease-specific) finding. Fever and tachycardia may also be present. 3. NURSING PRIORITY INTERVENTION: The priority nursing action is administration of supplemental oxygen to correct hypoxemia, as impaired gas exchange is the immediate threat to life. Using Maslow's hierarchy, physiologic needs (oxygenation) are always the first priority. The nurse should position the patient with the head of bed elevated (semi-Fowler's) to facilitate breathing, notify the physician immediately, and prepare for possible mechanical ventilation support if hypoxemia worsens. 4. ADDITIONAL NURSING ACTIONS: Continuous monitoring of oxygen saturation, respiratory rate, and level of consciousness; IV access for fluid management and medication administration; emotional support to reduce anxiety, which worsens oxygen consumption. 5. PREVENTION STRATEGY: The most effective prevention for FES is early immobilization of long-bone fractures. Immobilizing the fracture with a splint, cast, or surgical fixation (ORIF) prevents continued movement of bone fragments that releases more fat globules into the circulation. Gentle handling of patients with long-bone fractures also reduces fat embolism risk during transport and repositioning.

Spiral fractures in pediatric patients are a medico-legal trigger topic in the NLE. The nurse's legal duty under RA 9173 and PRC standards includes mandatory reporting of suspected child maltreatment. This connects orthopedic nursing to nursing law and ethics — a common integrative NLE item type.

Model Answer

A spiral fracture has a twisting fracture line, caused by a rotational force applied to the bone. When this type of fracture occurs in a child and the history provided by caregivers does not match the mechanism of injury expected to produce a spiral fracture, it should raise clinical suspicion of non-accidental trauma (child abuse), and must be reported in accordance with the legal and ethical obligations of the nurse.
