NLE Perioperative & Pain NursingPreoperative and Intraoperative NursingMemory Anchors

Filipino reviewers do well on Preoperative and Intraoperative Nursing once they have personal mnemonics — the anchors that make the concept local, memorable, and quick to surface under NLE time pressure. This page gathers the best-working anchors for Professional Regulation Commission (PRC) — Board of Nursing's typical Perioperative & Pain Nursing items on this chapter.

Exam context

On the NLE 2026, the Perioperative & Pain Nursing subtest carries a "Core" weight in Professional Regulation Commission (PRC) — Board of Nursing's pattern. Preoperative and Intraoperative Nursing lands at position 1st out of 3 in the standard review order. Target score is 75% weighted average with no sub-test below 60%, and roughly 50 items come from Perioperative & Pain Nursing on a typical NLE paper.

Preoperative and Intraoperative Nursing - Memory Anchors

Memory techniques — mnemonics, analogies, micro-stories, and visual associations — can triple your retention compared to passive reading alone. Your brain remembers stories, emotions, and vivid images far better than dry facts. For the NLE, where a single keyword difference can change the correct answer, these anchors give you reliable 'mental hooks' that fire automatically during exam pressure. Use each anchor consistently: read it, visualize it, say it aloud, and test yourself. The more senses you engage, the stronger the neural pathway. Think of these anchors as shortcuts your brain already knows how to follow — we are just building the road signs.

Informed Consent

Concept

Nurse's role in informed consent: WITNESS only — the SURGEON explains the procedure

Anchor Id

A1

Difficulty

medium

Memory Aid

Think of a wedding ceremony. The priest (surgeon) is the one who officially performs and explains the marriage rites. The principal sponsor (nurse) is simply a WITNESS — signing the certificate to confirm it happened properly. The sponsor never takes over and explains the vows for the priest. If the bride (patient) seems confused, the sponsor quietly tells the priest, 'Excuse me, she has a question.' The nurse NEVER explains the procedure — that is the surgeon's job.

Anchor Type

analogy

Why It Works

The wedding analogy maps perfectly to Filipino cultural experience. The hierarchy of roles is vivid and familiar, making role confusion nearly impossible.

Example Usage

Question asks: A patient says she does not understand the risks of her surgery. What should the nurse do? Recall the wedding sponsor — the nurse NOTIFIES the surgeon, does not explain independently.

Recall Trigger

Wedding ceremony + principal sponsor

Informed Consent

Concept

Consent must be signed BEFORE sedation — consent after sedation is INVALID

Anchor Id

A2

Difficulty

easy

Memory Aid

Imagine a student signing her enrollment form AFTER she drank a whole bottle of lambanog at the barrio fiesta. The registrar looks at the wobbly signature and says, 'Hindi ito valid!' (This is not valid!) A patient who has already received sedatives is like that student — they cannot truly understand or voluntarily decide. The signature is legally worthless. ALWAYS confirm consent is signed BEFORE any sedative is given.

Anchor Type

micro_story

Why It Works

The humorous Filipino cultural scenario creates an emotional memory tag. The phrase 'Hindi ito valid' serves as a verbal trigger that sticks.

Example Usage

Question: A patient is given diazepam and then asked to sign the consent form. Is this valid? Recall the lambanog student — sedation BEFORE signing = INVALID consent.

Recall Trigger

Drunk enrollment signature = invalid

NPO Status

Concept

NPO rule: 6–8 hours for SOLIDS, 2 hours for CLEAR LIQUIDS — prevents ASPIRATION

Anchor Id

A3

Difficulty

easy

Memory Aid

Remember: 'SOLID 6, LIQUID 2, or ASPIRATION is coming for YOU.' Visualize a clock: at the 6 o'clock position, a plate of rice (solids) is crossed out. At the 2 o'clock position, a glass of water (clear liquid) is crossed out. The danger hiding behind the clock is a pair of lungs filling with gastric contents — ASPIRATION.

Anchor Type

mnemonic

Why It Works

The rhyme creates an auditory hook while the clock visual spatially anchors the numbers. Filipino nurses instantly picture the rice plate, making it culturally concrete.

Example Usage

Question: How long before surgery should a patient stop eating solid food? Recall the rhyme — SOLID 6 — answer: 6 to 8 hours.

Recall Trigger

Clock with 6 and 2 — rice plate and water glass crossed out

Malignant Hyperthermia

Concept

Malignant hyperthermia: EARLY sign is TACHYCARDIA and rising CO2; LATE sign is HIGH TEMPERATURE; antidote is DANTROLENE

Anchor Id

A4

Difficulty

hard

Memory Aid

Use the acronym DANT for malignant hyperthermia: D – Dantrolene is the drug; A – Accelerated heart rate (tachycardia) is the EARLY sign; N – No delay — give dantrolene immediately; T – Temperature rise is the LATE sign (not the first!). Picture DANT as a superhero named Dantrolene who arrives EARLY when the heart starts racing, BEFORE the body bursts into flames (high fever).

Anchor Type

acronym

Why It Works

Students commonly confuse tachycardia (early) with high fever (late). The acronym DANT fixes the sequence, and the superhero image adds narrative structure.

Example Usage

Question: Which is an EARLY sign of malignant hyperthermia? Recall DANT: A = Accelerated heart rate. Answer: tachycardia and rising end-tidal CO2.

Recall Trigger

DANT superhero arrives early when the heart races

Regional Anesthesia — Spinal

Concept

Spinal anesthesia complications: HYPOTENSION and BRADYCARDIA (from sympathetic blockade); post-dural puncture HEADACHE managed with FLAT position and FLUIDS

Anchor Id

A5

Difficulty

medium

Memory Aid

Imagine Nurse Carla giving spinal anesthesia to a patient named Mang Ben. After the injection, Mang Ben says, 'Nurse, nahihilo ako at masakit ulo ko!' (Nurse, I feel dizzy and my head hurts!). Carla says, 'Higa ka nang flat at uminom ng maraming tubig!' (Lie flat and drink plenty of fluids!). The dizziness = hypotension/bradycardia from the sympathetic block. The headache = post-dural puncture headache. Flat + Fluids = the fix.

Anchor Type

micro_story

Why It Works

Filipino dialogue makes this scenario feel like a real ward experience. The patient's complaint directly triggers the clinical response, forming an automatic stimulus-response memory.

Example Usage

Question: After spinal anesthesia, a patient develops a severe headache. What is the priority nursing intervention? Recall Mang Ben — FLAT position and increase FLUIDS.

Recall Trigger

Mang Ben — dizzy + headache after spinal anesthesia

Intraoperative Counts

Concept

Surgical COUNT rule: counts done BEFORE the procedure, BEFORE closing a body cavity, and AT SKIN CLOSURE — to prevent RETAINED FOREIGN OBJECTS

Anchor Id

A6

Difficulty

medium

Memory Aid

Remember the phrase: 'B-B-C of counting' — Before (start), Before (cavity close), Closure (skin). Think of BBC News — they always report at the BEGINNING, BEFORE the main story ends, and at the CLOSING. If the count is wrong, the wound is NOT closed until resolved. 'No BBC, no closing!'

Anchor Type

mnemonic

Why It Works

BBC is a well-known acronym Filipino students recognize. The news broadcast analogy fits perfectly — reports happen at defined moments, just like counts.

Example Usage

Question: When are surgical counts performed? Recall BBC — Before the procedure, Before closing a cavity, at skin Closure. Answer: all three of these times.

Recall Trigger

BBC News = Before, Before, Closure

Concept

Surgical TIME-OUT verifies: CORRECT PATIENT, CORRECT PROCEDURE, CORRECT SITE — WHO Surgical Safety Checklist

Anchor Id

A7

Difficulty

easy

Memory Aid

Time-out = 3 C's: Patient, Procedure, Place (Site). Think of it as 'Checking Check-in at the Airport': (1) Correct PASSENGER name on ID, (2) Correct FLIGHT destination, (3) Correct GATE. Before any plane takes off (incision), EVERY crew member confirms all three. If one is wrong, the plane does NOT depart.

Anchor Type

acronym

Why It Works

Airport check-in is a universally familiar process with clear steps. The three checks map perfectly, and the consequence of error (wrong plane) mirrors wrong-site surgery severity.

Example Usage

Question: What does a surgical time-out verify? Recall the airport — Correct Patient, Procedure, and Site. Answer: all three must be confirmed before incision.

Recall Trigger

Airport check-in before the flight (incision)

Preoperative Physical Preparation

Concept

Remove NAIL POLISH preoperatively — so nail beds can be assessed for OXYGENATION (pulse oximetry and cyanosis)

Anchor Id

A8

Difficulty

easy

Memory Aid

Picture a pink-painted fingernail with a big red X over it, and next to it, a pulse oximeter probe giving a reading of 99%. The nail polish is the VILLAIN blocking the nurse's view of true tissue oxygenation. The oxygen probe can't 'see through' dark nail polish accurately, and cyanosis (bluish color) is hidden by the polish.

Anchor Type

visual_association

Why It Works

The visual contrast — pretty nail polish versus critical pulse ox reading — creates a memorable tension. Students who do their own nails will never forget this.

Example Usage

Question: Why is nail polish removed preoperatively? Recall the nail-with-X visual — to allow accurate pulse oximetry readings and assessment of cyanosis (oxygenation).

Recall Trigger

Painted nail with red X next to pulse oximeter

Preoperative Skin Preparation

Concept

CLIP, do not SHAVE hair for skin prep — shaving causes microabrasions that INCREASE infection risk

Anchor Id

A9

Difficulty

easy

Memory Aid

Think of a freshly shaved face versus a face with neatly trimmed stubble. After shaving, you often see tiny nicks and razor bumps — entry points for bacteria. A clipped face has no cuts. In surgery, those tiny nicks from shaving are like open doors for bacteria. CLIP = closed door. SHAVE = open wound. 'Clip para safe, shave para peligroso.'

Anchor Type

analogy

Why It Works

The everyday shaving experience is instantly relatable to male nursing students and anyone who shaves. The Filipino phrase reinforces the rule linguistically.

Example Usage

Question: What is the correct method of hair removal for preoperative skin preparation? Recall the razor nick analogy — CLIP, not shave, to prevent microabrasions and infection.

Recall Trigger

Shaving nicks = open door for bacteria; clipping = safe

Classification of Surgery

Concept

Classification of surgery by URGENCY: Emergent, Urgent, Elective, Optional

Anchor Id

A10

Difficulty

easy

Memory Aid

Use the acronym EUEO — 'Emergency Units Earn Overtime.' E = Emergent (immediate, life-threatening — e.g., ruptured aneurysm); U = Urgent (within 24–48 hours — e.g., acute appendicitis); E = Elective (planned — e.g., cataract); O = Optional (patient choice only — e.g., cosmetic). Remember: the more urgent, the less choice the patient has.

Anchor Type

acronym

Why It Works

The four categories are commonly confused in NLE questions. The acronym EUEO with the phrase 'Emergency Units Earn Overtime' provides a vivid workplace image Filipino nurses relate to.

Example Usage

Question: A patient with acute appendicitis requiring surgery within 24 hours is classified as? Recall EUEO — U = Urgent. Answer: Urgent surgery.

Recall Trigger

EUEO — Emergency Units Earn Overtime

Surgical Risk Factors

Concept

Factors that INCREASE surgical risk — obesity, malnutrition, diabetes, age extremes, smoking, anticoagulants, certain herbals

Anchor Id

A11

Difficulty

medium

Memory Aid

Use the mnemonic 'OLDMAS': O = Old age (and very young); L = Low nutrition (malnutrition); D = Diabetes; M = Medications (anticoagulants, corticosteroids, herbals like ginkgo); A = Age-related weight issues (Obesity); S = Smoking. Think of 'OLD MAS' as an old, overweight, chain-smoking lolo who takes too many herbal supplements — the highest-risk patient you've ever seen.

Anchor Type

mnemonic

Why It Works

The Filipino cultural image of a risky lolo patient is humorous and vivid. Each letter maps to a specific risk factor, making the list retrievable under pressure.

Example Usage

Question: Which patient has the HIGHEST surgical risk? Recall OLD MAS — a patient who is obese, diabetic, on anticoagulants, and a smoker has multiple risk factors stacked.

Recall Trigger

OLD MAS — the high-risk lolo

Preoperative Medications and Herbals

Concept

Herbal supplements that increase BLEEDING risk: Ginkgo, Garlic, Ginseng, Vitamin E (the 4 G's)

Anchor Id

A12

Difficulty

medium

Memory Aid

Remember the '4 G's that make you BLEED': Ginkgo, Garlic, Ginseng, and vitamin G-E (Vitamin E). Create the image of four bottles on a shelf in a health food store, all labeled with a blood drop warning sign. Every time you see herbal supplements in an NLE scenario, scan for these four names.

Anchor Type

mnemonic

Why It Works

Alliteration (4 G's) creates an auditory pattern. The visual of a health food store shelf is realistic — Filipino families often take these supplements.

Example Usage

Question: Which herbal supplement should the nurse flag before surgery because it increases bleeding risk? Recall the 4 G shelf — ginkgo, garlic, ginseng, or vitamin E.

Recall Trigger

Health food store shelf with blood drop warning: Ginkgo, Garlic, Ginseng, Vit E

Intraoperative Positioning

Concept

Intraoperative positioning: PAD BONY PROMINENCES to prevent pressure injury and NERVE DAMAGE

Anchor Id

A13

Difficulty

easy

Memory Aid

Visualize placing a person on a hardwood floor to sleep — without a banig (sleeping mat), every bony point (heels, sacrum, elbows, occiput) would be painful and injured. The anesthetized patient is lying on that hard OR table and CANNOT feel the pain or shift position to protect themselves. Every bony prominence needs a 'banig' — padding. No padding = pressure ulcer or nerve damage.

Anchor Type

visual_association

Why It Works

The Philippine banig (woven sleeping mat) analogy is culturally immediate and tactile. The inability of the unconscious patient to self-protect mirrors the helplessness a student can empathize with.

Example Usage

Question: What is the primary reason bony prominences are padded during intraoperative positioning? Recall the banig — the anesthetized patient cannot feel pain or reposition; padding prevents pressure injury and nerve damage.

Recall Trigger

Sleeping on hardwood floor without banig

Operating Room Team Roles

Concept

Scrub nurse vs. Circulating nurse roles

Anchor Id

A14

Difficulty

medium

Memory Aid

Think of a restaurant kitchen: the SCRUB NURSE is the CHEF — works inside the clean sterile zone (kitchen), handles all the sterile instruments (knives, tools), and keeps the 'kitchen clean.' The CIRCULATING NURSE is the WAITER — moves in and out, communicates between the kitchen and the outside world (the dining area), documents orders, and coordinates everything outside the sterile field. Chef = sterile field. Waiter = circulates, documents, manages.

Anchor Type

analogy

Why It Works

Restaurant roles are universally understood. The scrub/sterile = kitchen inside the line; circulate/outside = waiter who moves freely. The contrast is crisp and non-overlapping.

Example Usage

Question: Which OR nurse is responsible for documenting and coordinating outside the sterile field? Recall the restaurant — the WAITER (circulating nurse) moves outside the sterile zone and documents.

Recall Trigger

Chef (scrub) inside kitchen; Waiter (circulating) everywhere else

Surgical Asepsis

Concept

Sterility rules: below waist level = NOT STERILE; edges of sterile package (2.5 cm) = contaminated; if in doubt = contaminated

Anchor Id

A15

Difficulty

hard

Memory Aid

Remember 'The Waist-Edge-Doubt Rule' using the phrase: 'WAist, EDge, DOubt — all CONTAMINATED, no doubt!' W = Waist (below waist level is unsterile); E = Edge (edges of sterile drape/package are contaminated); D = Doubt (if in doubt, throw it out). Visualize a sterile gown: the 'sterile zone' is from chest to waist. Drop your hands below your waist and they instantly become dirty.

Anchor Type

mnemonic

Why It Works

The phrase creates a memorable three-rule package. The visual of gloved hands dropping below the waist 'becoming dirty' is vivid and action-based, burning the rule into memory.

Example Usage

Question: A scrub nurse drops their gloved hand below the level of the OR table. What is the implication? Recall WAED — below waist = contaminated. The glove is now considered non-sterile.

Recall Trigger

WAED — Waist, Edge, Doubt = Contaminated

OR Zone Classification

Concept

OR Zone classification: Unrestricted, Semi-restricted, Restricted (Restricted = requires MASK in addition to scrubs)

Memory Aid

Imagine a VIP concert venue with three areas: (1) LOBBY — anyone can enter in street clothes (Unrestricted zone). (2) BACKSTAGE — only people in crew uniforms and caps, no street clothes (Semi-restricted, scrub attire and caps). (3) MAIN STAGE — only crew with uniforms, caps, AND face masks because the singer (patient) is performing and everything must be clean (Restricted zone = masks required). The closer you get to the patient, the more protective gear you need.

Anchor Type

micro_story

Why It Works

Concert venue zones are intuitive and progressive. The escalating protection requirement follows logically from the 'VIP proximity' narrative — easy to sequence.

Example Usage

Question: What attire is required in the restricted zone of the OR? Recall the Main Stage — scrubs, cap, AND mask. Answer: surgical attire plus mask.

Recall Trigger

Concert venue: Lobby → Backstage → Main Stage (mask added)

Moderate Sedation

Concept

Moderate (conscious) sedation: patient maintains OWN AIRWAY; monitor SpO2 and LOC; reversal agents: NALOXONE (opioids) and FLUMAZENIL (benzodiazepines)

Anchor Id

A17

Difficulty

hard

Memory Aid

Remember 'N-F for Not Fully asleep': N = Naloxone reverses Narcotics (opioids); F = Flumazenil reverses benzo-Fright (benzodiazepines). The patient in moderate sedation is 'Not Fully asleep' — they still breathe on their own and respond to you. But if the sedation deepens too far, you reach for NF — Naloxone or Flumazenil depending on which drug caused the problem.

Anchor Type

mnemonic

Why It Works

NF as initials for 'Not Fully asleep' simultaneously encodes the two reversal drugs. Students often confuse which reversal agent goes with which drug; the N-Narcotic and F-benzo linkage makes it clear.

Example Usage

Question: A patient in moderate sedation becomes unresponsive after receiving midazolam. What reversal agent should be available? Recall NF — Flumazenil reverses benzodiazepines (like midazolam).

Recall Trigger

NF = Not Fully asleep — Naloxone/Narcotics, Flumazenil/benzo

Memory Aid

Picture a barangay health center where the nurse checks a patient's ID bracelet AND asks the patient to state their name before giving an injection — TWO checks, not one. Now picture a surgeon drawing a big arrow on the correct knee before an operation. These are two separate safety acts: 'Check WHO they are (2 IDs)' and 'Check WHERE to operate (site marking).' Together they form a shield against two of surgery's most dangerous errors.

Anchor Type

visual_association

Why It Works

The barangay health center image is culturally grounded for Filipino nursing students. Breaking the two acts into separate vivid images prevents them from being merged into one vague idea.

Example Usage

Question: Before transferring a patient to the OR, what two safety steps must the nurse complete regarding patient identity and the surgical site? Recall barangay ID + arrow — verify TWO identifiers and confirm surgical site marking.

Recall Trigger

Barangay ID check + arrow on knee

Imagine a nurse named Dikle teaching five exercises before surgery — her name IS the lesson. 'DICLE prevents postop complications!'

Anchor Type

acronym

Why It Works

Inventing a Filipino-sounding name as an acronym creates a personification memory hook. The nurse character makes the abstract content concrete and sequential.

Example Usage

The OR team used standard gloves during her surgery, and within minutes her blood pressure crashed and she broke out in hives — full anaphylaxis on the table. Now, every Filipino nurse remembers: 'Tanong mo ang latex bago mag-opera!' (Ask about latex before surgery!) A tiny rubber glove caused a near-fatal crisis. Always flag it, always prepare latex-free.

Anchor Type

micro_story

Why It Works

The vivid drama of intraoperative anaphylaxis creates a fear-based memorable tag. The Filipino reminder phrase ('Tanong mo') makes it actionable and culturally embedded.

Example Usage

Formula Mnemonics

Formula

NPO Rule: Solids = 6–8 hours; Clear liquids = 2 hours before surgery

Mnemonic

'SOLID 6, LIQUID 2, or ASPIRATION is coming for YOU' — Visualize a clock with a rice plate at 6 o'clock and a water glass at 2 o'clock, both crossed out.

When To Use

When asked about NPO guidelines, when planning preoperative preparation timing, or when evaluating whether a patient is cleared for surgery.

What Each Part Means

Solid food (rice, meat, heavy meals) takes longer to clear the stomach; clear liquids (water, juice without pulp) clear in about 2 hours. The purpose of both restrictions is to ensure an empty stomach and prevent aspiration of gastric contents under anesthesia.

Formula

Surgical Count Timing: Before Procedure + Before Cavity Closure + Skin Closure = 3 counts

Mnemonic

BBC — Before (start), Before (cavity), Closure (skin). 'No BBC, no closing the wound!'

When To Use

Any NLE question about when counts are performed, what to do if a count is incorrect, or who is responsible for counts in the OR.

What Each Part Means

Count 1 (Before Procedure): Establishes baseline count of all sponges, sharps, and instruments before surgery begins. Count 2 (Before Cavity Closure): Ensures nothing is left inside a body cavity before it is closed. Count 3 (Skin Closure): Final check before the skin is sutured shut — the last chance to catch a retained object.

Formula

Malignant Hyperthermia Response: DANTROLENE + Cooling measures + Supportive care

Mnemonic

DANT: D = Dantrolene (drug), A = Accelerated HR (early sign), N = No delay, T = Temperature rise (late sign). Give DANT IMMEDIATELY.

When To Use

Any question about malignant hyperthermia management, identification of early vs. late signs, or pharmacologic treatment of this anesthetic emergency.

What Each Part Means

Dantrolene is the ONLY specific antidote for malignant hyperthermia — it works by preventing calcium release from the sarcoplasmic reticulum, stopping the uncontrolled muscle metabolism. Cooling measures include ice packs, cool IV fluids, and surface cooling blankets. Supportive care addresses the resulting acidosis, hypoxia, and dysrhythmias.

Quick Recall Chains

Chain Title

Preoperative Checklist Sequence (Pre-op Steps)

Recall Test

Without looking, list the 9 preoperative preparation steps in order. Start with 'Nurse Lara checks WHO the patient is...'

Memory Chain

Story: 'Nurse Lara goes to her patient's room to prepare for surgery. First, she checks WHO the patient IS (two IDs) and MARKS the site. She opens the chart — CONSENT is there. She records VITALS. She asks the patient to PEE. She removes all the BLING (jewelry, dentures, contacts, nail polish). She dresses the patient in a GOWN + ID band. She gives the PRE-OP MEDS. Finally, she CLIPS the hair — no shaving!' Each action builds on the previous one like Lara walking around the room systematically.

Items To Remember

  • Verify two patient identifiers
  • Mark surgical site
  • Confirm signed consent is on chart
  • Record baseline vital signs
  • Have patient void (or insert catheter)
  • Remove jewelry, dentures, nail polish, prostheses
  • Dress patient in gown and ID band
  • Administer preoperative medications as ordered
  • Perform skin preparation (clip hair)

Chain Title

Malignant Hyperthermia: Signs and Management Sequence

Recall Test

What is the EARLY sign of malignant hyperthermia? What drug is given? What do you do BEFORE giving the drug? (Answer: tachycardia + rising CO2; dantrolene; STOP the triggering agent)

Memory Chain

Remember DANT in a burning building: The ALARM (tachycardia + CO2) goes off FIRST — that is the EARLY warning. The walls get STIFF (muscle rigidity). Then the whole building is on FIRE (high temperature — late sign). The firefighter DANTROLENE arrives IMMEDIATELY when the alarm sounds, does NOT wait for the fire. He brings COOLING hoses and SUPPORTIVE backup crew. The building is saved because Dantrolene came EARLY.

Items To Remember

  • Unexplained tachycardia (EARLY sign)
  • Rising end-tidal CO2 (EARLY sign)
  • Muscle rigidity
  • Rapidly rising temperature (LATE sign)
  • Stop triggering anesthetic agents immediately
  • Administer DANTROLENE
  • Apply cooling measures
  • Provide supportive care (monitor ABGs, treat acidosis)

Types of Anesthesia: Features and Key Facts

Recall Test

Name the six types of anesthesia from most to least profound. For each, state one distinguishing feature or risk.

Memory Chain

Think of a spectrum from DEEPEST to most AWAKE: 'GENERAL puts you COMPLETELY under (unconscious, intubated). SPINAL drops everything BELOW (hypotension, headache risk). EPIDURAL is like SPINAL's slower cousin (labor pain, postop). NERVE BLOCK targets ONE area like a sniper. LOCAL is tiny — a small numb patch. MODERATE lets you TALK but stay calm (you keep your own airway).' Walking from 'fully asleep' to 'slightly sedated' is the memory walk.

Items To Remember

  • General: loss of consciousness, amnesia, analgesia, muscle relaxation — ETT/LMA airway
  • Spinal: subarachnoid space injection — hypotension, bradycardia, post-dural puncture headache
  • Epidural: epidural space — used for labor and postop pain
  • Nerve block: specific nerve or plexus anesthesia
  • Local: small area numbing for minor procedures
  • Moderate sedation: conscious, own airway, reversible with naloxone or flumazenil

Chain Title

Surgical Urgency Classification (EUEO)

Recall Test

A patient with a ruptured spleen needs immediate surgery. What is the classification? (Answer: Emergent) A patient with gallstones scheduled for next week? (Answer: Elective)

Memory Chain

EUEO = 'Emergency Units Earn Overtime.' Picture the ER (Emergent — running to save a life), the surgical ward admitting at night (Urgent — 24–48 hours), the outpatient clinic scheduling next month (Elective — planned), and a beauty clinic (Optional — patient's choice). Moving from left to right: less emergency, more patient choice.

Items To Remember

  • Emergent — immediate, life-threatening (ruptured aneurysm)
  • Urgent — within 24–48 hours (acute appendicitis)
  • Elective — planned, not immediately life-threatening (cataract repair)
  • Optional — patient preference only (cosmetic surgery)

Chain Title

Preoperative Teaching: DICLE

Recall Test

What does each letter in DICLE stand for? How does each teaching point prevent a specific postoperative complication?

Memory Chain

Remember NURSE DIKLE who does five exercises before every shift: she takes DEEP BREATHS first, uses her INCENTIVE SPIROMETER, then COUGHS while hugging a pillow (splinting), does LEG RAISES at the bedside, then takes an EARLY MORNING WALK. She prevents pneumonia, DVT, and atelectasis just by doing these five things every day.

  • Incentive spirometry
  • Coughing and splinting the incision
  • Leg exercises
  • Early ambulation
