NLE Paediatric Nursing — Paediatric GI, Genitourinary & Neurologic DisordersMemory Anchors

Memory aid

Imagine a firstborn baby boy named 'Pepe' (a very common Filipino name for a firstborn son). Every time Pepe's Nanay tries to feed him, his tummy is like a broken fire hydrant — milk shoots out PROJECTILE style, flying across the room. It is NOT green (not bilious — no bile because the block is ABOVE the duodenum). When the doctor checks Pepe's tummy, she feels a small olive (like the olives in your Nanay's ensalada) in the right upper area. Pepe is only 3 weeks old and is always hungry but keeps vomiting. The pylorus is so thick and muscular (like a hypertrophic muscle) it blocks the outlet.

Why it works

The story personalizes a Filipino firstborn (Pepe), uses a vivid projectile image and a tangible food item (olive) to anchor the three classic signs simultaneously. Emotional and cultural familiarity deepens encoding.

Example usage

NLE question: 'A 4-week-old male infant has been vomiting after every feed. The vomit is forceful and not green. The nurse palpates a small, firm, movable mass in the right upper quadrant. What condition is suspected?' — Recall 'Pepe + fire hydrant + olive' → Pyloric Stenosis.

Recall trigger

Think: 'Baby Pepe + fire hydrant + olive in the ensalada'

Memory aid

Use the acronym 'VOMIT MAKES ALKALINE BABIES': V = Vomiting (projectile); M = Metabolic alkalosis; A = Acidic gastric juice is LOST; K = K+ (potassium) drops; A = Also Cl- (chloride) drops; B = Baby needs fluids BEFORE surgery. Shorter version: remember 'ACID OUT = ALKALINE IN' — the baby vomits out hydrochloric acid (HCl) from the stomach, so the body becomes alkalotic. No HCl = no balance = alkalosis + low Cl + low K (kidneys try to compensate by retaining H+ and spilling K+).

Why it works

The phrase 'ACID OUT = ALKALINE IN' is a logical cause-and-effect hook. The full acronym covers all components tested by NLE. Connecting the pathophysiology (HCl loss) makes it meaningful, not just rote.

Example usage

NLE question: 'What ABG finding is expected in a 5-week-old with pyloric stenosis?' — Recall 'ACID OUT = ALKALINE IN' → Metabolic alkalosis with low Cl and low K.

Recall trigger

Think: 'What happens when stomach acid keeps flying out? ACID OUT = ALKALINE IN'

Memory aid

Think of the colon as an MRT train line (LRT/MRT in Manila). Ganglion cells are the TRAIN OPERATORS — without operators, the train (poop/meconium) cannot move. In Hirschsprung disease, a section of the track has NO operators (absent ganglion cells), so the station (colon) is DEAD SILENT — no movement, no meconium passes in 24–48 hours. The diagnostic test (rectal biopsy) is like sending an inspector DOWN to the tracks to check if operators are present. If the inspector finds NO operators → confirmed Hirschsprung.

Why it works

Every Filipino student living in Metro Manila knows MRT/LRT delays caused by missing operators — this turns an abstract pathophysiology into a vivid, relatable urban experience. The analogy maps directly onto the mechanism.

Example usage

NLE question: 'A neonate has not passed meconium for 36 hours. The abdomen is distended. What is the definitive diagnostic test?' — Recall 'inspector checking the tracks' → Rectal biopsy.

Recall trigger

Think: 'MRT with no operators — no train movement, no meconium'

Memory aid

Chant: 'HIRO has ENTEROCOLITIS — EXPLOSIVE poo, FEVER, DISTENSION, this means SEPSIS IS THREATENIN'! Report it RIGHT AWAY, do not DELAY!' (Say it fast like a rap beat.) Remember: ENTER = ENTER the danger zone. COLITIS = colon is inflamed. It is the MOST DANGEROUS complication of Hirschsprung — do not confuse with normal 'ribbon stools.'

Why it works

Rhyme and rhythm exploit the phonological loop in working memory, making the complication memorable and distinguishable from other GI conditions. The word 'ENTER' serves as a dual trigger (enterocolitis + entering danger).

Example usage

NLE question: 'A child with Hirschsprung disease post-colostomy develops sudden explosive diarrhoea, high fever, and abdominal distension. What is the priority nursing action?' — Recall the rap → Report immediately — signs of enterocolitis/sepsis.

Recall trigger

Think: 'Hirschsprung + EXPLOSIVE diarrhoea = ENTER the danger zone'

Memory aid

Picture a Filipino baby holding a 'longganisa' (sausage) and crying so hard she pulls her knees up to her chest (colicky pain). She squeezes the longganisa so hard that dark red ube jam (currant-jelly stool = blood + mucus) oozes out. The LONGGANISA = sausage-shaped abdominal mass. The UBE JAM = currant-jelly stool (dark red, mucus-mixed). The KNEE-HUGGING = colicky pain from telescoping bowel. Connect: 'Longganisa + Ube Jam + Knee Hug = Intussusception triad.'

Why it works

Culturally familiar Filipino foods (longganisa, ube jam) create a vivid mental image. The baby's posture (knees to chest) is physically memorable. Associating all three signs with one scene reduces cognitive load.

Example usage

NLE question: 'A 7-month-old infant screams intermittently and draws his knees to his chest. The nurse notes dark, mucus-like stool in the diaper. What shape of mass is expected on palpation?' — Recall the visual → Sausage-shaped (longganisa) mass → Intussusception.

Recall trigger

Think: 'Longganisa + Ube Jam + Knee Hug'

Memory aid

The doctor says, 'We can DIAGNOSE AND FIX at the same time!' — like a plumber who sends a camera into the pipe to find the blockage AND uses water pressure to UNBLOCK it in one visit. This is the air/barium enema. If after the enema the baby passes a normal BROWN stool (not currant-jelly), the nurse should REPORT IT — it means the telescoped bowel has POPPED BACK into place, like a sock being turned right-side out. 'Normal brown stool = GOOD news = reduction successful.'

Why it works

The plumber analogy explains the dual diagnostic-therapeutic function in one metaphor. The sock analogy for 'telescoping bowel returning to normal' makes the pathophysiology concrete. The specific trigger (normal brown stool) is highlighted as the 'good news' signal.

Example usage

NLE question: 'After a hydrostatic enema for intussusception, the infant passes a normal brown stool. What does this indicate?' — Recall the sock analogy → Successful reduction of the intussusception.

Recall trigger

Think: 'Plumber camera + water pressure = fix in one visit; brown stool = sock popped back'

Memory aid

Remember 'WILMS = WARN, ISOLATE, LEAVE, MASS, SURGERY': W = WARN everyone — post a NO-PALPATION sign on the bedside; I = It's on one side ONLY — does NOT cross midline; L = Leave it alone — gentle bathing; M = Mass is firm and non-tender; S = Surgery within 24–48 hours + chemo ± radiation. The BIG rule: 'DO NOT TOUCH THE WILMS MASS — touching can RUPTURE the capsule and SPREAD cancer cells everywhere (seeding).' Think of it like a fragile bubble — pop it and the cancer escapes.

Why it works

The acronym provides a structured recall of five key facts. The 'fragile bubble' analogy for the encapsulated tumour vividly explains WHY palpation is dangerous, making the rule meaningful rather than arbitrary — meaningful rules are better retained.

Example usage

NLE question: 'A 3-year-old with a suspected Wilms tumour is admitted. What is the PRIORITY nursing intervention?' — Recall 'WARN = post NO-PALPATION sign' → Post a sign at the bedside: Do Not Palpate the Abdomen.

Recall trigger

Think: 'WILMS = WARN everyone + fragile bubble — DO NOT POP'

Memory aid

Use the 'LEAKY vs. BLEEDING pipe' analogy: NEPHROTIC = The glomerulus is a LEAKY PIPE that lets protein escape silently — lots of protein pours out into urine (frothy urine), albumin drops, water seeps into tissues (massive oedema, periorbital in the morning), but the pipe itself is NOT bleeding. BP is NORMAL or LOW. THINK: Puffy face, frothy urine, NO blood, no hypertension. GLOMERULONEPHRITIS = The glomerulus is a BLEEDING, INFLAMED pipe — immune complex attack after STREP (1–2 weeks later) → BLOOD in urine (cola-coloured), HYPERTENSION, and mild oedema. THINK: Post-strep + cola urine + high BP.

Why it works

The leaky vs. bleeding pipe distinction maps perfectly onto the pathophysiology and creates a binary memory structure. The contrast between the two conditions is what NLE tests most — this analogy makes that contrast crystal clear.

Example usage

NLE question: 'A 5-year-old has severe periorbital oedema, frothy urine, and normal blood pressure. What condition is this?' — Recall 'LEAKY pipe = no blood, no HTN, massive protein loss' → Nephrotic Syndrome.

Recall trigger

Think: 'Leaky (nephrotic = protein out, puffy, frothy) vs. Bleeding (AGN = blood in urine, high BP, post-strep)'

Memory aid

Use the mnemonic 'BIG HEAD SUNSET CRIES': B = Bulging, tense anterior fontanelle; I = Increasing head circumference (measure daily!); G = Gaps between sutures (widely separated sutures); H = High-pitched cry; E = Eyes = 'sunset eyes' (sclera visible above iris, downward gaze); A = Altered/irritable behaviour; D = Distended scalp veins; S = Separated sutures. The image: a baby with a BIG HEAD, looking down at the SUNSET (eyes downward), crying with a HIGH-PITCHED wail. The anterior fontanelle is BULGING like a water balloon.

Why it works

The phrase 'BIG HEAD SUNSET CRIES' is itself a visual scene — a crying baby at sunset with a large head. The acronym organises eight signs into one memorable phrase with built-in imagery.

Example usage

NLE question: 'A 3-month-old is observed to have the upper portion of the iris covered by the lower eyelid, with sclera visible above. Head circumference has increased 4 cm in 2 weeks. What condition is suspected?' — Recall 'SUNSET EYES + BIG HEAD' → Hydrocephalus.

Recall trigger

Think: 'BIG HEAD SUNSET CRIES — the baby is watching the sunset (eyes down) and has a water balloon on the head'

Memory aid

After the VP shunt surgery, the brain needs to adjust slowly to the new drainage. Imagine a dam (the shunt) that was just installed. If you RAISE the head too fast, the water (CSF) drains TOO QUICKLY — like opening the dam floodgates — and the brain collapses inward, causing SUBDURAL HEMATOMA. So the rule is: keep the child FLAT to control flow. Lie on the NON-OPERATIVE side — you do NOT want pressure on the new shunt hardware. Think: 'NEW DAM = FLAT START. Too fast drain = brain collapse.' The nurse gradually raises the head only as ORDERED by the doctor.

Why it works

The dam analogy explains the physiological reason behind the positioning rule — understanding why prevents confusing it with other post-op positions. The vivid consequence (brain collapse) makes the rule emotionally sticky.

Example usage

NLE question: 'Immediately post-op after VP shunt insertion, how should the nurse position the infant?' — Recall 'new dam = flat start' → Keep flat and on the non-operative side.

Recall trigger

Think: 'VP shunt = new dam — FLAT start, NON-operative side, raise gradually'

Memory aid

Remember 'Dr. CUSHING is VERY LATE to the party': C = Cushing's triad; U = Uh-oh — this is LATE (ominous); B = Bradycardia (heart slows); H = Hypertension with WIDENED pulse pressure; I = Irregular respirations (Cheyne-Stokes). Quick recall: 'BHI = Bad Heart Is' — Brady, Hypertension, Irregular breathing. The triad means the brainstem is being compressed. LATE = you should have acted EARLIER. If you see Cushing's triad, the brain is in severe danger.

Why it works

The phrase 'VERY LATE' attached to the Cushing name encodes the critical clinical implication (late sign = danger). The BHI acronym gives rapid recall of all three components. Multiple encoding paths (name + acronym + meaning) strengthen retention.

Example usage

NLE question: 'A child post-head trauma develops a heart rate of 52 bpm, BP of 160/60 mmHg, and irregular breathing. What does this indicate?' — Recall 'BHI = Cushing's Triad = LATE sign of ↑ICP' → Imminent brain herniation; notify physician immediately.

Recall trigger

Think: 'Dr. CUSHING is VERY LATE — BHI = Brady, Hypertension, Irregular breathing'

Memory aid

Think of CP as a 'FROZEN SCREENSHOT of a brain injury.' The brain injury happened once (at birth or prenatally), took a photo (screenshot), and the photo does NOT get worse. But the BODY tries to grow around the frozen screenshot — so the muscles become stiff (spastic), the legs cross like scissors when walking (scissoring gait), and the child cannot control movements. The TREATMENT goal is to MAXIMISE what the child CAN do — like helping someone work around a frozen app: use alternative tools (PT, OT, speech therapy, braces). 'NON-PROGRESSIVE = the screenshot does not get darker.'

Why it works

The 'frozen screenshot' analogy captures both the non-progressive nature (the image does not worsen) and the static yet disabling characteristics of CP. Filipino students' familiarity with smartphones makes this immediately relatable and novel.

Example usage

NLE question: 'A child with cerebral palsy has recently developed worsening scoliosis. The parents ask if the CP is getting worse. How should the nurse respond?' — Recall 'frozen screenshot' → The brain lesion itself is non-progressive, but secondary complications like musculoskeletal changes can develop as the child grows.

Recall trigger

Think: 'Frozen screenshot — won't get worse, but body adapts with stiffness (spastic scissors)'

Memory aid

Use the acronym 'SPLINT': S = Side-lying (turn to the side for airway); P = Protect from injury (pad surfaces, ease to floor); L = Loosen tight clothing; I = Insert NOTHING in the mouth (no tongue blade, no fingers — this is the most common wrong answer!); N = Never restrain the child; T = Time the seizure (duration + document type, onset). 'SPLINT' is ironic because you do NOT actually put a splint on a seizing child — you just remember the word SPLINT to protect them. Also have Suction and O2 available; STAY with the child.

Why it works

The irony of using the word SPLINT (a restraint device) for a situation where you do NOT restrain makes it memorable through cognitive dissonance. The acronym covers all NLE-tested seizure priorities in one word.

Example usage

NLE question: 'A 3-year-old begins to have a tonic-clonic seizure in the hospital bed. What is the FIRST nursing action?' — Recall SPLINT → S = Turn to side-lying position immediately.

Recall trigger

Think: 'SPLINT — ironic because you do NOT splint or restrain'

Memory aid

Chant: 'FIVE MINUTES or MORE, can't wait anymore — GIVE IV BENZO at the door! Lorazepam or Diazepam, it's the FIRST TO GIVE, make the seizure STOP so the brain can LIVE!' Five minutes = the magic number. First drug = BENZOdiazepine (IV lorazepam or diazepam). Think of '5-BEN': 5 minutes → BENzodiazepine. If that fails, next anticonvulsants are given (phenytoin, phenobarbital, etc.) but benzodiazepine is ALWAYS FIRST.

Why it works

The rhyming chant encodes the time threshold AND first-line drug simultaneously. The '5-BEN' shortcut provides a rapid recall trigger for exam conditions. Rhyme exploits the phonological loop for durable storage.

Example usage

NLE question: 'A child has been seizing for 7 minutes. What is the priority pharmacologic intervention?' — Recall '5-BEN' → IV lorazepam or IV diazepam (benzodiazepine) — first-line for status epilepticus.

Recall trigger

Think: '5 minutes = 5-BEN = Benzodiazepine first'

Memory aid

Visualise a cartoon character with a big smile but their GUMS are growing like a jungle overgrowth — 'Phenytoin makes the GUMS GROW a GARDEN.' The word PHENYTOIN contains 'PHENY' — think 'FAT GUMS.' Phenytoin = puffy/fat gums (gingival hyperplasia). Therefore, the nurse must teach METICULOUS ORAL CARE — brush gently, use soft toothbrush, see the dentist regularly. ALSO REMEMBER: Never stop phenytoin ABRUPTLY — abrupt stopping triggers REBOUND SEIZURES (like a fire alarm that won't turn off if you rip out the battery wrong).

Why it works

The 'gum garden' visual is absurd and vivid — absurdity is one of the most powerful encoding strategies. The separate alarm analogy for abrupt withdrawal encodes the second key teaching point.

Example usage

NLE question: 'A child on long-term phenytoin therapy comes for a follow-up. What should the nurse include in health teaching?' — Recall 'fat gums garden' → Teach meticulous oral hygiene to manage gingival hyperplasia; remind never to stop medication abruptly.

Recall trigger

Think: 'PHENYTOIN = FAT GUMS GARDEN + never stop abruptly'

Memory aid

Use the mnemonic 'PALE FROG': P = Prone or side-lying position (protect the sac); A = Avoid pressure on the sac (no diapers over it); L = Latex-free environment (high latex allergy risk!); E = Environment must be clean (prevent infection); F = Folic acid prevents neural tube defects (maternal supplement before and during early pregnancy); R = Report any sac leakage or rupture immediately; O = Ongoing monitoring for hydrocephalus (associated condition); G = Gentle handling, no pressure on sac. Image: A pale frog lying face-down on a lily pad (prone) with a delicate bubble on its back.

Why it works

The 'PALE FROG' image is unusual and vivid — the frog lying prone with a bubble on its back mirrors the clinical picture of a myelomeningocele patient perfectly. Each letter maps to a specific care priority tested by NLE.

Example usage

NLE question: 'A neonate is born with a myelomeningocele sac at the lumbar area. What is the PRIORITY nursing intervention before surgery?' — Recall 'PALE FROG' → P = Prone position + sterile moist dressing to protect the sac.

Recall trigger

Think: 'PALE FROG face-down on a lily pad with a bubble on its back'

Memory aid

Use 'DARK CABIN': D = Droplet precautions IMMEDIATELY (isolation); A = Antibiotics IV — give PROMPTLY after cultures; R = Reduce stimulation (quiet, dark room — photophobia); K = Kernig's sign positive (knee won't extend when hip is flexed); C = CSF — lumbar puncture for diagnosis; A = Antibiotics (second reminder — speed is critical!); B = Brudzinski's sign positive (hip/knee flex when neck is flexed); I = Infant clue = Bulging fontanelle + paradoxical irritability; N = Notify contacts — meningococcal disease is NOTIFIABLE (public health requirement under Philippine DOH reportable disease list).

Why it works

The phrase 'DARK CABIN' reinforces the 'dark and quiet room' intervention directly in the trigger. Each letter maps to a tested NLE fact. The repetition of 'Antibiotics' (A appears twice) emphasises the urgency of timely antibiotic administration.

Example usage

NLE question: 'A 2-year-old presents with fever, nuchal rigidity, photophobia, and a petechial rash. What is the FIRST nursing action?' — Recall 'DARK CABIN' → D = Institute Droplet precautions immediately.

Recall trigger

Think: 'DARK CABIN — bring the meningitis patient to a dark cabin FAST with antibiotics'

Memory aid

Remember '100-50-20' like a DISCOUNT sale: 'FIRST 10 kg gets 100 mL/kg/day (BIG DISCOUNT), NEXT 10 kg gets 50 mL/kg/day (HALF-PRICE), EVERY kg ABOVE 20 gets 20 mL/kg/day (SMALL BONUS).' Or use '4-2-1' for hourly rate: First 10 kg = 4 mL/kg/hr; next 10 kg = 2 mL/kg/hr; above 20 kg = 1 mL/kg/hr. EXAMPLE: A 25 kg child: (10 × 100) + (10 × 50) + (5 × 20) = 1000 + 500 + 100 = 1600 mL/day OR (10 × 4) + (10 × 2) + (5 × 1) = 40 + 20 + 5 = 65 mL/hr.

Why it works

The 'DISCOUNT SALE' analogy with descending discounts (100→50→20) creates a logical, progressive memory structure. The worked example reinforces calculation confidence. Chunking the three tiers reduces the formula to three paired numbers.

Example usage

NLE question: 'Calculate the daily maintenance fluid requirement for a 14 kg child.' — Recall discount sale: (10 × 100) + (4 × 50) = 1000 + 200 = 1200 mL/day.

Recall trigger

Think: 'DISCOUNT SALE: 100 for the first 10, 50 for the next 10, 20 for the rest'

Memory aid

Imagine little 'Neftali' (a boy with Nephrotic syndrome) whose face is so puffy he can barely open his eyes in the morning. His doctor gives him PREDNISONE (steroids) to FIX the leaky glomerular filter. Meanwhile, Neftali's Nanay is told: 'NO SALTY FOOD (low sodium) — salt makes the water stay in tissues and makes his face more puffy.' Every morning, Nanay weighs Neftali on the same scale (daily weight = best fluid monitor), measures his tummy (abdominal girth for ascites), and checks his urine for bubbles (frothy = protein). Nanay also keeps Neftali away from sick classmates — because the STEROIDS lower his immunity and losing immunoglobulins makes him VERY PRONE to INFECTION.

Why it works

The story format contextualises multiple nursing interventions around one character (Neftali and Nanay), making the care plan memorable as a sequence of daily actions. Filipino family dynamics (Nanay as caregiver) resonate culturally.

Example usage

NLE question: 'A child with nephrotic syndrome is being managed at home. What dietary restriction is most important?' — Recall Nanay's rule: 'No salty food = LOW SODIUM diet to prevent worsening oedema.'

Recall trigger

Think: 'Puffy-faced Neftali + prednisone + Nanay doing daily weight + no salty food + keep away from sick kids'

Memory aid

Chant: 'ONE TO TWO mL per kg per hour — that's the pee-power that shows you the shower! WEIGH the baby EVERY DAY — weight is the MOST SENSITIVE way! Fontanelle sunken? Mucous dry? Skin tents up when you ask it why? All these signs say DEHYDRATION is nigh!' Summary: Urine output = 1–2 mL/kg/hr. Best single hydration indicator = DAILY WEIGHT (most sensitive). Other signs: fontanelle, mucous membranes, skin turgor, capillary refill.

Why it works

The rhyme encodes the numeric target (1–2 mL/kg/hr), the priority assessment tool (weight), and the list of hydration indicators in a single musical structure. The playful language ('pee-power') makes it enjoyable to recall.

Example usage

NLE question: 'What is the MOST reliable indicator of fluid balance in a 6-month-old infant?' — Recall 'WEIGH every day is most sensitive' → Daily weight.

Recall trigger

Think: 'ONE TO TWO pee-power + WEIGH every day = best hydration check'

Mnemonic

DISCOUNT SALE: 100 for the FIRST 10 (big sale!), 50 for the NEXT 10 (half-price!), 20 for every kg ABOVE 20 (small bonus). Or: '4-2-1' for hourly rates (4 mL/kg/hr, 2 mL/kg/hr, 1 mL/kg/hr).

When to use

Use when calculating IV fluid orders for paediatric patients, checking if a fluid order is appropriate, or answering NLE questions about maintenance fluids. ALWAYS subtract the oral intake from the total maintenance requirement when calculating additional IV fluids.

What each part means

100 mL/kg/day: Infants (0–10 kg) have the highest metabolic rate and fluid needs per kg. 50 mL/kg/day: Children 10–20 kg need less per kg as body size increases. 20 mL/kg/day: Larger children need the least per kg. The 4-2-1 rule gives the same numbers as hourly infusion rates.

Mnemonic

'ONE TO TWO = the pee-power clue.' If urine output < 1 mL/kg/hr = OLIGURIA = suspect dehydration or renal compromise. If > 3–4 mL/kg/hr = suspect over-hydration or diabetes insipidus.

When to use

Use when evaluating I&O in paediatric patients, assessing renal perfusion, monitoring hydration status post-op or in illness, and prioritising nursing assessments in fluid-imbalance questions on the NLE.

What each part means

1 mL/kg/hr is the minimum acceptable urine output in infants. 2 mL/kg/hr is the ideal target. Below 1 = concern; above 3-4 without osmotic reason = investigate. Example: A 10 kg infant should produce 10–20 mL/hr of urine.

Mnemonic

BHI = 'Bad Heart Is (in trouble)' — Brady, Hypertension, Irregular breathing. Or: 'BIG BAD BRAIN = Brady + Big BP + Bizarre breathing.' This is a LATE, OMINOUS sign — if you see BHI, act IMMEDIATELY.

When to use

Use when identifying late signs of increased ICP in neurological patients (hydrocephalus, head trauma, meningitis, post-VP shunt). Immediate physician notification is required. Do not confuse with early ICP signs (irritability, headache, vomiting).

What each part means

Bradycardia: Vagal response to brainstem compression. Hypertension (widened pulse pressure = systolic rises, diastolic falls): Cushing reflex trying to maintain cerebral perfusion. Irregular respirations (Cheyne-Stokes or ataxic): Brainstem respiratory centre compression. This triad signals impending herniation.

Recall test

Without looking: What is the classic stool description in intussusception? What electrolyte imbalance occurs in pyloric stenosis? What is the definitive diagnostic test for Hirschsprung disease?

Memory chain

THREE BABIES walking into a clinic: Baby PEPE (3–5 weeks old, firstborn boy) SHOOTS milk from his mouth like a fire hydrant — the doctor feels an OLIVE in his tummy (pyloric stenosis). Baby HIRO (newborn) has been staring at the wall — no poop for 2 days because his train (colon) has no operators (absent ganglion cells) — the doctor sends an inspector (rectal biopsy) to confirm (Hirschsprung). Baby LONGGANISA (7 months) is screaming and pulling knees to chest because her bowel has telescoped — she gets an enema and finally passes a NORMAL BROWN STOOL (reduced!) — everyone cheers (Intussusception).

Items to remember

• Pyloric stenosis: 3–5 weeks, firstborn male, projectile non-bilious vomiting, olive mass, hypochloremic hypokalemic metabolic alkalosis, pyloromyotomy
• Hirschsprung disease: absent ganglion cells, no meconium 24–48h, ribbon stools, rectal biopsy, colostomy → pull-through, watch for enterocolitis
• Intussusception: 5–9 months, knees to chest, sausage mass, currant-jelly stool, air/barium enema, normal brown stool = reduction

Recall test

Which renal condition has hypertension? Which has more severe oedema? What is the first-line treatment for nephrotic syndrome? What triggers acute glomerulonephritis?

Memory chain

TWO KIDNEY TWINS: LEAKY KIDNEY (Nephrotic) SILENTLY loses protein like a broken sieve — face puffs up like a pandesal (periorbital oedema), urine is FROTHY (protein), BP is NORMAL. Treat with PREDNISONE. BLEEDING KIDNEY (AGN) was ATTACKED by STREP 1–2 weeks ago — urine is COLA-COLOURED (haematuria), BP is HIGH, mild face puffing. RESTRICT SALT and FLUIDS. Remember: 'Leaky = Protein out, Puffy, Normal BP. Bleeding = Blood in urine, Hypertension, Post-Strep.'

Items to remember

• Nephrotic: massive proteinuria, hypoalbuminemia, severe oedema (periorbital), hyperlipidemia, normal/low BP, frothy urine, treat with prednisone
• AGN (post-strep): haematuria (cola-coloured urine), hypertension, mild oedema, oliguria, occurs 1–2 weeks after strep, monitor BP, restrict Na/fluids

Recall test

What is the post-op position after VP shunt? What type of CP is most common? What is the FIRST nursing action for bacterial meningitis? What does SPLINT stand for? What prevents neural tube defects?

Memory chain

Five neurologic patients walk into a ward: HYDRO has a BIG HEAD (measure circumference), gets a VP SHUNT, and lies FLAT post-op. CP SPASTIC SCISSOR WALKER is doing PT/OT to MAXIMISE function. MENING walks in wearing a MASK (droplet) and needs DARK CABIN treatment (antibiotics NOW!). SEIZURE CHILD needs a SPLINT (the ironic acronym). FROG BABY (spina bifida) lies PRONE on the bed with a PALE sterile dressing over the sac, LATEX-FREE environment, and mother is reminded about FOLIC ACID for prevention.

Items to remember

• Hydrocephalus: measure head circumference, VP shunt, post-op FLAT on non-operative side, watch for shunt malfunction/infection, Cushing's triad = LATE sign
• Cerebral palsy: non-progressive, spastic = most common (scissoring), multidisciplinary, aspiration precautions, maximise function
• Bacterial meningitis: droplet precautions FIRST, lumbar puncture, IV antibiotics ASAP, dark quiet room, Kernig's/Brudzinski's, notifiable disease
• Seizure: SPLINT (Side-lying, Protect, Loosen, Insert nothing, Never restrain, Time); status epilepticus >5 min = IV benzodiazepine
• Spina bifida: PALE FROG (Prone, Avoid pressure, Latex-free, Environment clean, Folic acid, Report leakage, Observe for hydro, Gentle care)

Recall test

What is the PRIORITY nursing action for Wilms tumour on admission? Does the mass cross the midline? How soon should surgery be done? What is the rationale for the no-palpation rule?

Memory chain

Imagine a FRAGILE BUBBLE (encapsulated tumour) on the child's RIGHT kidney. A sign on the bedside reads: 'DO NOT TOUCH — FRAGILE BUBBLE INSIDE.' Every nurse, doctor, and visitor who comes near the bed sees the sign. The bubble is on ONE side only (does not cross midline). The child is bathed GENTLY so the bubble does not pop. Within 24–48 hours, the surgeon carefully REMOVES the bubble (nephrectomy). Chemo follows to kill any remaining cells. The nurse checks BP (Wilms can cause hypertension) and watches for blood in the urine.

Items to remember

• DO NOT palpate the abdomen
• Post a NO-PALPATION sign at the bedside
• Mass is firm, non-tender, on ONE side, does NOT cross midline
• Handle and bathe gently
• Surgery within 24–48 hours
• Chemo ± radiation post-op
• Monitor BP and urine (haematuria)

Recall test

What is the first-line drug for status epilepticus? What side effect requires oral hygiene teaching? Which drug requires liver function monitoring? What happens if anticonvulsants are stopped abruptly?

Memory chain

The seizure drug LADDER: FIRST RUNG = BENZO (lorazepam/diazepam — the fastest door to STOP the seizing). SECOND RUNG = PHENYTOIN (gives fat gums — teach oral care). MAINTENANCE RUNGS = PHENO-PHENO-VAL-CARBA-LEVETI ('Please Pass Very Cold Lemonade'). NEVER kick the ladder (never stop abruptly) or you fall back into seizures. Valproic acid guards the LIVER (hepatotoxic — monitor LFTs).

Items to remember

• Status epilepticus (>5 min): IV lorazepam or IV diazepam (benzodiazepine) — FIRST
• Second-line: IV phenytoin or fosphenytoin
• Maintenance anticonvulsants: phenytoin, phenobarbital, valproic acid, carbamazepine, levetiracetam
• Phenytoin → gingival hyperplasia → meticulous oral care
• Valproic acid → hepatotoxicity → monitor LFTs
• NEVER stop anticonvulsants abruptly — triggers rebound seizures
