Paediatric Hematologic, Oncologic & Genetic Disorders - Memory Anchors
Memory anchors transform complex clinical content into unforgettable mental images, stories, and associations. Research in cognitive psychology shows that emotionally vivid, story-based, and visually rich memories are encoded in long-term memory far more effectively than rote repetition. For the NLE, where you must recall dozens of specific facts under pressure, these techniques act like mental shortcuts — a single trigger word or image instantly unlocks a full cluster of facts. Think of each anchor as a 'hook' in your brain: once you hang a vivid story or image on a concept, it never falls off. Use these anchors during your review, then test yourself with the recall triggers. The goal is to make every key fact feel like something you personally experienced — because your brain remembers experiences, not bullet points.
Memory anchors
Leukemia — most common childhood cancer; ALL most common type; peak age 2-5 years
Memory aid
Imagine a 4-year-old boy named AL (short for ALL) who loves to hoard all the toys in the daycare. He keeps grabbing and grabbing until the other kids (normal blood cells) have nothing left. The daycare teacher (bone marrow) is overwhelmed because AL never stops multiplying. AL is 4 years old — right in the peak range of 2-5 years. He is the MOST popular (most common) troublemaker in the classroom (childhood cancers). His hoarding leaves the room chaotic: no red cars (RBCs), no security guards (WBCs), no building blocks (platelets) — pancytopenia!
Why it works
The story personalizes an abstract pathophysiology into a concrete character, making the age, type, and consequence all tied to one vivid narrative.
Example usage
Question: Which is the most common childhood cancer and what is its peak incidence age? — Think of AL the 4-year-old hoarder → Acute Lymphoblastic Leukemia, peak 2-5 years.
Recall trigger
Think of '4-year-old AL' the toy hoarder
Leukemia — pancytopenia triad: anemia + neutropenia (infection) + thrombocytopenia (bleeding); infection is the leading cause of death
Memory aid
Use the acronym AIB — 'AL Is Bleeding' — but remember the ORDER of danger: Infection kills first! A = Anemia (pallor, fatigue), I = Infection/neutropenia (the KILLER — leading cause of death), B = Bleeding/thrombocytopenia (petechiae, bruising). So recite: 'AL Is Bleeding, but Infection Kills.' Another layer: picture the three guards of the bone marrow FIRED by leukemia — the Red Guard (RBCs), the White Guard (WBCs/neutrophils), and the Platelet Police — all gone.
Why it works
The acronym AIB creates a quick recall scaffold, and the 'killer' emphasis on Infection ensures prioritization is never forgotten — critical for Maslow-based NLE questions.
Example usage
Question: What is the leading cause of death in leukemia? — AIB → I = Infection kills first → neutropenia → leading cause of death.
Recall trigger
AIB — AL Is Bleeding, but Infection Kills
Neutropenic precautions: no fresh flowers/plants, no raw food, no crowds, no rectal temps, no IM injections, fever = emergency, no live vaccines
Memory aid
Remember the phrase: 'NO FIRM CLAV' — No Fresh flowers, No IM injections, No Raw food, No Macrowds (crowds), No Clive vaccines (live vaccines — no 'Live' vaccines = CLAV). Better yet, think of a hospital room DOOR SIGN: 'FRIENDS NOT ALLOWED: Flowers, Raw food, Injections (IM), Enteric/rectal temps, No crowds, Do-not-vaccinate-live.' The word FRIEND reminds you of the 6 banned items: F=Flowers, R=Raw food, I=IM injections, E=Every rectal temp forbidden, N=No crowds, D=Do not give live vaccines. BONUS: Fever in a neutropenic child = CODE RED — treat as emergency!
Why it works
The FRIEND acronym converts 6 separate rules into one familiar word. The 'door sign' visual ties it to the actual clinical setting students will encounter.
Example usage
Question: A leukemic child on chemo develops a temperature of 38.2°C. What is the priority action? — FRIEND reminds you: fever = emergency → notify physician immediately, do not delay.
Recall trigger
FRIEND on the hospital room door — who is NOT allowed in
Hemophilia — X-linked recessive; affects males, carried by females; Hemophilia A = Factor VIII (most common); Hemophilia B = Factor IX
Memory aid
Think of hemophilia as a BROKEN BRIDGE (missing clotting factor). The bridge has TWO lanes: Lane A (Factor 8 = the MAIN highway, used by 80-85% of traffic = most common) and Lane B (Factor 9 = the secondary road = Christmas/Hemophilia B). The bridge was built by the mother (X-linked carrier) but only the SONS drive across it — daughters carry the broken blueprint but never fall through. Remembering A=8: 'A looks like an 8 rotated' — draw an A, rotate it 90 degrees and it resembles 8. Hemophilia A = Factor VIII.
Why it works
The bridge analogy makes X-linked transmission visual and intuitive. The rotated A=8 trick is a direct visual-spatial mnemonic for the single most tested fact about hemophilia.
Example usage
Question: A male child presents with hemarthrosis. His mother is a known carrier. What factor is most likely deficient? — Broken bridge, Lane A = Factor VIII (most common, Hemophilia A).
Recall trigger
Broken bridge built by mother; Lane A (the main highway) = Factor 8
Hemophilia — acute joint bleed management: RICE + Factor replacement; avoid aspirin, NSAIDs, IM injections, contact sports
Memory aid
For a bleeding joint, think: 'Give the joint RICE and CAKE.' RICE = Rest, Ice, Compression, Elevation (plus factor replacement — the most important treatment). CAKE = Cannot Aspirin/NSAIDs, No IM injections, Keep away from contact sports, Extra pressure on wounds. Picture a child with a swollen knee sitting on a RICE bag eating CAKE carefully — that's your image. The rice bag soothes the knee (RICE protocol) and the CAKE reminds you of birthday rules ('no rough games at birthday parties, no aspirin in the food').
Why it works
Dual acronyms (RICE and CAKE) split the positive interventions from the prohibitions, making it easier to recall both simultaneously without confusion.
Example usage
Question: A child with hemophilia has a swollen, painful right knee. What nursing interventions are priority? — RICE → Rest, Ice, Compression, Elevation + factor replacement; CAKE → no aspirin/NSAIDs, no IM injections.
Recall trigger
RICE bag and CAKE for the child with hemarthrosis
Sickle Cell Disease — autosomal recessive (HbS); triggers of crisis: Hypoxia, Dehydration, Infection, Cold, Acidosis
Memory aid
Remember the crisis triggers with 'CHAID': Cold, Hypoxia, Acidosis, Infection, Dehydration. Picture a sickle (the farming tool) that only bends and CHAID (chains/shackles — Filipino kids know 'tanikala') when these 5 conditions strike. Alternatively, think: 'A sickle gets CHAID when you leave it in the COLD, AIRLESS, INFECTED, WET-THEN-DRY conditions.' In Filipino context: imagine a rice farmer's sickle left in cold rainy weather (cold + wet = dehydration risk) — it rusts and bends (sickles the blood).
Why it works
CHAID creates a phonetically distinct acronym. The Filipino farming/sickle image makes the word 'sickle' literally connect to agricultural tools familiar in Philippine culture.
Example usage
Question: Which condition would most likely precipitate a sickle cell crisis in a child? — CHAID: Cold → vasoconstriction → sickling → crisis.
Recall trigger
CHAID — sickle gets chained by these 5 triggers
Sickle Cell Crisis management priority: Hydration, Heat/Warmth, Oxygen, Pain control
Memory aid
Remember 'HHOP' — like a hip-hop dance move! H = Hydration (IV/oral fluids), H = Heat/Warmth (NEVER cold — cold causes sickling), O = Oxygen (correct hypoxia), P = Pain control (opioids for severe pain). Picture a Filipino DJ yelling 'HHOP! HHOP!' at a party while pouring water (Hydration), turning on the heat lamp (Heat), handing out oxygen tanks (Oxygen), and giving pain meds (Pain). The energy and absurdity make it memorable. CRITICAL: Never apply cold — this is the opposite of what feels intuitive and a common distractor in NLE!
Why it works
The hip-hop acronym is culturally resonant with younger Filipino students and the absurd party image makes the sequence vivid. The 'Never cold' emphasis prevents the most common exam mistake.
Example usage
Question: A child in sickle cell crisis is crying in pain. What is the priority nursing management? — HHOP: Hydration first, then Heat/warmth, Oxygen, Pain control (opioids).
Recall trigger
HHOP like a hip-hop move — DJ at the sickle cell party
Thalassemia major — severe microcytic anemia; chronic transfusions cause IRON OVERLOAD (hemosiderosis); treated with chelation: deferoxamine (parenteral) or deferasirox (oral)
Memory aid
Imagine a child named Thal (short for Thalassemia) who keeps receiving BAON (packed lunch) every month — the baon is blood transfusions. But Thal's locker (body) fills up with too many metal lunch boxes (iron overload/hemosiderosis) until the locker is RUSTING (organ damage — heart, liver). A janitor named DEFO (Deferoxamine) comes with a magnet to pull out all the extra metal from the locker. DEFO comes in two forms: Defo with a NEEDLE (deferoxamine = parenteral/injection) and Defo with a TABLET (deferasirox = oral). Remember: Too much iron = rusty organs. DEFO removes the rust.
Why it works
The Filipino 'baon' concept makes monthly transfusions relatable. The rusty locker vividly represents hemosiderosis, and the two forms of DEFO distinguish the routes of administration.
Example usage
Question: A child with beta-thalassemia major receives monthly transfusions. What complication must the nurse monitor for and how is it managed? — Rusty locker = iron overload/hemosiderosis → DEFO = chelation therapy (deferoxamine IV/SC or deferasirox oral).
Recall trigger
Thal's rusting locker full of iron lunch boxes — DEFO the janitor
Iron-deficiency anemia — oral ferrous sulfate administration: empty stomach + Vitamin C, avoid milk, use straw (stains teeth), tarry stools normal, keep locked away (overdose risk)
Memory aid
The iron tablet has FIVE RULES — remember 'EVATS': E = Empty stomach (or between meals), V = Vitamin C to boost absorption (orange/citrus juice), A = Avoid milk (blocks absorption), T = Through a straw (prevents teeth staining), S = Store locked away (overdose = leading cause of child poisoning death). Then remember the two EXPECTED EFFECTS: Dark/tarry stools (normal — reassure parents!) and possible Constipation. Say: 'EVATS gives dark stools, that's okay!' Picture a Filipino lola preparing iron medicine for her apo: she pours it through a straw into OJ (Vitamin C), locks the bottle in the kabinet (cabinet), and tells her apo 'huwag matakot sa itim na tae!' (don't be scared of black poop!).
Why it works
EVATS is a novel 5-letter code that covers all administration rules. The Filipino grandmother scenario makes the teaching moment feel real and culturally grounded.
Example usage
Question: What should the nurse teach parents about administering liquid ferrous sulfate to a toddler? — EVATS: Empty stomach, Vitamin C, Avoid milk, Through a straw, Store locked → plus expect dark stools.
Recall trigger
EVATS — lola giving iron to her apo through a straw with orange juice
Down Syndrome (Trisomy 21) — features: hypotonia, upslanting palpebral fissures, epicanthal folds, flat face, protruding tongue, single palmar crease, wide first-second toe gap
Memory aid
Build a 'Down Syndrome Portrait' in your mind: Start from TOP to BOTTOM. HEAD: flat face, upslanting eyes with epicanthal folds (imagine eyes that look slightly upward like a smiling emoji 😊 with extra folds at the inner corner). MOUTH: protruding tongue (always slightly out — tongue is too big for the small oral cavity). BODY: floppy/hypotonic (imagine a rag doll — limp, soft). HAND: look at the palm — ONE straight line across (single transverse/simian crease instead of the usual two curved lines). FEET: gap between big toe and second toe (like the flip-flop/tsinelas gap is extra wide). Say: 'FLAT FACE, FLOPPY BODY, ONE LINE HAND, WIDE TSINELAS GAP.'
Why it works
Building a head-to-toe visual portrait anchors multiple features simultaneously. The tsinelas (Filipino flip-flop) reference makes the toe gap image culturally vivid and instantly recognizable.
Example usage
Question: A newborn has a flat facial profile, upslanting eyes, and a single transverse palmar crease. What condition is suspected? — Portrait: flat face + one-line hand = Down Syndrome (Trisomy 21).
Recall trigger
The Down Syndrome Portrait — flat face to tsinelas gap, top to bottom
Down Syndrome — associated conditions: congenital heart defects (AV canal most common), duodenal atresia, hypothyroidism, atlantoaxial instability, increased leukemia risk, hearing/vision problems
Memory aid
Remember the complications with 'CHAD HiL': C = Congenital Heart defects (AV canal — most common), H = Hirschsprung and duodenal atresia (GI), A = Atlantoaxial instability (protect the neck!), D = Developmental delay/intellectual disability, H = Hypothyroidism, i = infections (respiratory, immunodeficiency), L = Leukemia risk (increased). Say: 'CHAD HiL has Down syndrome and all its complications.' Picture a Filipino boy named Chad Hill (a flat hill, like his flat facial profile) who has all these health problems listed on his medical chart.
Why it works
CHAD HiL creates a memorable character name that also references the flat facial profile. Each letter anchors a specific associated condition, preventing omissions on the exam.
Example usage
Question: A child with Down syndrome is scheduled for activity. What precaution must the nurse prioritize before allowing physical activity? — CHAD HiL: A = Atlantoaxial instability → assess neck stability before contact sports or physical therapy.
Recall trigger
Chad the boy from the flat hill — his medical chart of complications
Inheritance patterns: Autosomal recessive (sickle cell, thalassemia, PKU, CF, galactosemia) vs. X-linked recessive (hemophilia A/B, G6PD, Duchenne MD) vs. Chromosomal (Down syndrome)
Memory aid
Think of inheritance as TYPES OF EXAM CHEATING: AR (Autosomal Recessive) = 'Both parents must carry the cheat sheet hidden' — both must be carriers; the child only gets the disease if they receive two copies (25% risk). Examples: 'STPGC' = Sickle cell, Thalassemia, PKU, G...alactosemia, Cystic fibrosis. X-linked Recessive = 'The cheat sheet is on the X chromosome — mom hides it, but sons get caught!' — Mother carries it silently; sons (XY) always get caught; daughters (XX) are carriers. Examples: Hemophilia A/B, G6PD, Duchenne. Chromosomal = 'The exam printer made an extra copy by mistake!' — Trisomy 21 = one extra chromosome 21 printed.
Why it works
The cheating/exam analogy is darkly humorous and highly relatable to students who have sat through many exams. The three distinct cheating methods clearly separate the three inheritance types.
Example usage
Question: Parents ask about the risk of sickle cell disease in future children. Both parents are carriers. What is the recurrence risk? — AR = both carry hidden cheat sheet → 25% chance each pregnancy.
Recall trigger
Three types of exam cheating — hidden cheat sheets (AR), mom hides the X cheat sheet (XLR), extra printed copy (chromosomal)
PKU — autosomal recessive; phenylalanine accumulates → intellectual disability; detected by NBS heel-prick after feeding; management = low-phenylalanine diet + avoid aspartame (NutraSweet)
Memory aid
Meet baby PHENYL, born in the Philippine General Hospital. Baby Phenyl looks normal but CANNOT process phenylalanine (the amino acid in all high-protein foods). The NBS (Newborn Screening) nurse pricks Phenyl's heel 48 hours after feeding and catches him early. The diet doctor prescribes: 'No high-protein food, no artificial sweetener ASPARTAME (it releases phenylalanine when digested — it's a trap!).' Without treatment, Phenyl's brain floods with phenylalanine and intellectual disability develops. With treatment — a special low-Phe formula and diet — Phenyl can grow normally. The NBS heel prick literally saved his brain. Remember: 'Prick the heel at 24-72 hours → save the brain from PHENYLflood.'
Why it works
The baby character Phenyl personalizes the condition and makes the consequence of missed diagnosis emotionally impactful. The 'aspartame trap' is memorable because it contradicts the intuition that 'sugar-free' is healthy.
Example usage
Question: A mother of a PKU infant asks if diet cola (aspartame) is safe. What should the nurse advise? — Baby Phenyl story: aspartame releases phenylalanine → NO, avoid all aspartame-containing products.
Recall trigger
Baby Phenyl's heel prick at 48 hours — the prick that saved the brain
Philippine Newborn Screening (RA 9288) — 5 conditions screened: Congenital Hypothyroidism, CAH, PKU, Galactosemia, G6PD deficiency; done at 24-72 hours after birth
Memory aid
Remember the 5 NBS conditions with 'CH-PKG' pronounced 'CHEE-PAKIG' (like a Filipino exclamation!): CH = Congenital Hypothyroidism, P = PKU, K = Kongenital Adrenal Hyperplasia (CAH — the K is for 'Kortisel'/cortisol problem), G = Galactosemia, G6PD = the bonus G (G6PD deficiency). So: 'CHEE-PAKIG' = CH, P, K (CAH), G (galactosemia), G6PD. The heel prick is done at 24-72 hours — remember: 'Prick at Day 1-3, ideally after feeding.' Under RA 9288, every Filipino newborn must be screened. The nurse's role: educate parents, ensure the test is done, and refer positive results.
Why it works
CHEE-PAKIG is a fun Filipino-sounding exclamation that encodes all five conditions. Anchoring to RA 9288 reinforces the Philippine legal context — a favorite NLE angle.
Example usage
Question: Under RA 9288, which conditions are included in the mandatory Philippine Newborn Screening Program? — CHEE-PAKIG: Congenital Hypothyroidism, PKU, CAH, Galactosemia, G6PD deficiency.
Recall trigger
CHEE-PAKIG — the Filipino NBS battle cry at 24-72 hours
G6PD deficiency — X-linked recessive; avoid oxidative triggers: fava beans, naphthalene (mothballs/tingting), sulfa drugs, antimalarials
Memory aid
G6PD-deficient red blood cells are like THIN-WALLED BUBBLES (fragile RBCs). Certain TRIGGERS are like sharp pins that POP the bubbles (hemolysis). The 4 pins to avoid: 1. FAVA BEANS (patani) — many Filipino families eat these; 2. NAPHTHALENE = MOTHBALLS / TINGTING (very common in Filipino homes — used to repel insects); 3. SULFA DRUGS (like sulfamethoxazole — common antibiotic); 4. ANTIMALARIALS (like primaquine — especially relevant in Philippine malaria-endemic areas). Remember: 'Do NOT pop my G6PD bubbles with FATS-M' — Fava beans, Antimalarials, Tingting/mothballs (naphthalene), Sulfa drugs, (and other oxidative stressors).
Why it works
The bubble analogy makes hemolysis viscerally intuitive. The Filipino household context (mothballs/tingting, patani) makes the triggers personally relevant and impossible to forget.
Example usage
Question: Parents of a G6PD-deficient infant ask what to avoid at home. What is the nurse's priority teaching? — FATS-M pins: Fava beans, Antimalarials, Tingting/naphthalene, Sulfa drugs — remove these from the home.
Recall trigger
Thin-walled bubbles popped by FATS-M pins — G6PD Filipino home danger
ITP — isolated thrombocytopenia after viral illness; normal WBC and Hgb; distinguish from leukemia (leukemia drops ALL cell lines); management: bleeding precautions, often self-limiting
Memory aid
ITP is like a TARGETED AIRSTRIKE on platelets only — the immune system (army) gets a bad tip after a virus (the spy) and attacks ONLY the platelet barracks. The RBC barracks and WBC barracks are UNTOUCHED (normal Hgb and WBC — this is how you differentiate from leukemia, which bombs ALL barracks = pancytopenia). The child with ITP looks otherwise WELL (playing normally, eating well) but has petechiae and bruises — a confusing-looking but stable patient. Compare to leukemia: that child looks SICK (pallor, fever, bone pain, lymphadenopathy). NLE tip: ITP = isolated low platelets + well-looking child + after viral illness = NOT leukemia.
Why it works
The military analogy makes the 'isolated' nature of thrombocytopenia visually clear, and the contrast with leukemia directly addresses the most common NLE discriminator between these two conditions.
Example usage
Question: A child has petechiae and a platelet count of 20,000 but normal WBC and hemoglobin, two weeks after a viral infection. What condition is most likely? — Targeted airstrike = ITP (isolated thrombocytopenia post-viral, normal other cell lines, well-appearing child).
Recall trigger
Targeted airstrike — only platelets hit, child still looks well
Chemotherapy side effects — nausea (antiemetics BEFORE chemo), mucositis (saline mouth care, no alcohol mouthwash), alopecia (reassure hair regrows), vincristine causes constipation/peripheral neuropathy
Memory aid
Remember chemo side effects with 'NAMA-VC': N = Nausea (give ondansetron BEFORE chemo — prevention first!), A = Alopecia (hair falls but GROWS BACK — reassure always), M = Mucositis (mouth sores — saline rinse, no alcohol mouthwash, soft bland food), A = Anemia/myelosuppression, V = Vincristine → Constipation + peripheral neuropathy (numbness/tingling in hands/feet), C = Caution with infections (neutropenia). 'NAMA-VC' in Filipino sounds like 'namamahay VC' (VC = vincristine causing constipation). Say: 'Before chemo, give NAMA-VC prep: antiemetic first, protect the mouth, warn about vincristine constipation.'
Why it works
NAMA-VC creates a Filipino-resonant mnemonic (namamahay = homesick/adjusting) that attaches a cultural feeling to the adaptation process children undergo during chemotherapy.
Example usage
Question: A child starting vincristine chemotherapy complains of constipation. Is this expected? — NAMA-VC → V = Vincristine causes constipation + peripheral neuropathy → YES, expected side effect; manage with increased fluids, fiber, stool softeners.
Recall trigger
NAMA-VC — the chemo checklist before starting treatment
Thalassemia — autosomal recessive; frontal bossing + maxillary changes from bone marrow expansion; 'Cooley's anemia' = beta-thalassemia major; microcytic hypochromic anemia
Memory aid
Picture a child whose FOREHEAD is swollen and bumpy like a FOOTBALL HELMET (frontal bossing) and whose cheeks are puffy like a chipmunk (maxillary changes). This happens because the bone marrow is DESPERATELY EXPANDING (trying to make more RBCs) and pushes the skull bones outward. This child is also very PALE (severe anemia) and has a BIG BELLY (hepatosplenomegaly). The image: 'Football helmet head + chipmunk cheeks + pale + big belly = Cooley's anemia (beta-thalassemia major).' Remember Cooley like a 'cool' football player with the helmet head and chipmunk cheeks who is always pale and tired.
Why it works
The exaggerated physical image (football helmet + chipmunk) makes the bony changes of thalassemia viscerally memorable and easily drawn as a quick mental sketch during the exam.
Example usage
Question: A child has frontal bossing, maxillary prominence, pallor, and hepatosplenomegaly. What condition is suspected? — Football helmet Cooley's image = beta-thalassemia major.
Recall trigger
Football helmet head + chipmunk cheeks + pale + big belly = Cooley
Hydroxyurea in sickle cell disease — reduces crisis frequency by raising fetal hemoglobin (HbF); functional asplenia in sickle cell → increased infection risk → immunizations important
Memory aid
Hydroxyurea is like a PEACETIME AGREEMENT for sickle cell RBCs: it persuades the body to produce more baby-type hemoglobin (HbF — fetal hemoglobin) which does NOT sickle. Think: HydroxyURea = HydroxyURban development that converts the sick adult hemoglobin district into a peaceful fetal hemoglobin neighborhood. Fewer crises = less pain = better quality of life. Also remember: in sickle cell, the spleen gets damaged over time (autosplenectomy/functional asplenia) — the spleen is the body's SECURITY GUARD against encapsulated bacteria. No spleen = no guard = HIGH INFECTION RISK → complete all vaccines (especially pneumococcal, meningococcal, Hib).
Why it works
The urban development analogy makes a complex pharmacological mechanism (raising HbF) intuitive. The security guard analogy for the spleen makes functional asplenia and its consequence unforgettable.
Example usage
Question: Why is immunization especially important in a child with sickle cell disease? — Spleen security guard gone (functional asplenia) → high risk for encapsulated organisms → pneumococcal, meningococcal, Hib vaccines are priority.
Recall trigger
Hydroxyurea = urban renewal for fetal Hgb; damaged spleen = no security guard → vaccines!
Hemophilia lab values — PTT is prolonged; platelet count NORMAL; bleeding time NORMAL (distinguish from thrombocytopenia/ITP where platelet count is low)
Memory aid
Rhyme: 'In Hemophilia, PTT goes LONG, platelets and bleeding time stay STRONG. No broken platelets, just factor GONE — that's why the PTT takes so long!' Breakdown: PTT (partial thromboplastin time) measures the INTRINSIC pathway — where Factors VIII and IX work. If they are missing, the PTT is prolonged. But platelets (measured by platelet count and bleeding time) are normal because they are not the problem. Contrast with ITP: 'In ITP, platelets are FEW, PTT stays normal, just platelets flew!' This rhyme-pair cements the critical distinction for NLE distractors.
Why it works
Rhymes leverage phonological memory loops — the rhythmic pattern makes both the correct and incorrect lab values stick together, preventing the most common exam mix-up.
Example usage
Question: Which lab value is expected to be abnormal in hemophilia A? — Rhyme: PTT goes LONG → prolonged PTT; platelet count normal; bleeding time normal.
Recall trigger
PTT goes LONG, platelets stay STRONG — hemophilia rhyme

A lola is preparing iron medicine for her 18-month-old apo with iron deficiency anemia. She mixes it in milk to hide the taste and skips the orange juice. She leaves the bottle on the kitchen counter. Name ALL the mistakes she made (at least 4).
Answer
Mistake 1: Mixed with milk (blocks absorption — avoid milk). Mistake 2: No orange juice/Vitamin C (needed to enhance absorption). Mistake 3: Left on counter (must be LOCKED AWAY — iron overdose = leading cause of child poisoning death). Bonus mistake: Should give through a straw (liquid iron stains teeth); should give on empty stomach between meals
Memory link

A Filipino mother asks you why her G6PD-deficient baby cannot use the mothballs (tingting) she puts in the baby's cabinet. She also asks if patani (fava bean) soup is safe for the baby. What is your answer, and what is the pathophysiology in one sentence?
Answer
Both mothballs (naphthalene) and fava beans (patani) are oxidative triggers that destroy G6PD-deficient red blood cells (hemolysis). G6PD-deficient RBCs cannot handle oxidative stress → fragile bubbles popped by FATS-M pins (Fava beans, Antimalarials, Tingting/naphthalene, Sulfa drugs). Teach the mother to remove these from the home entirely.
Memory link
A15 — FATS-M pins popping thin-walled G6PD bubbles in the Filipino home
Formula mnemonics
Oral Iron Dose = 3-6 mg/kg/day of elemental iron (in divided doses)
Mnemonic
3-6 for the SICK (Small Iron Correction for Kids): '3 to 6 mg per kilo, divided like sharing — that's the iron dose for kids!' Remember: 3-6 because it's between the 3 fingers and 6 fingers you hold up to show a child's age range (most common in infants/toddlers to 6 years). Dosing in divided doses (usually 3x/day with meals or between meals).
When to use
Whenever calculating or verifying the oral iron dose for a child diagnosed with iron-deficiency anemia; also used for anticipatory guidance when educating parents about dosing
What each part means
3-6 = the therapeutic range of elemental iron in mg; kg = child's body weight in kilograms; per day = total daily dose; divided doses = split into 2-3 portions across the day to maximize absorption and minimize GI side effects
Recurrence Risk: Autosomal Recessive (carrier x carrier) = 25% affected, 50% carrier, 25% unaffected
Mnemonic
The '1-2-1 Rule' of AR genetics: '1 sick, 2 carriers, 1 free — out of every 4 children, that's the guarantee!' Or use a Punnett square shortcut: 'Quarter sick, Half hidden (carrier), Quarter clear.' Apply to sickle cell, thalassemia, PKU, galactosemia — anytime both parents are carriers of an AR gene.
When to use
Genetic counselling questions where both parents are carriers of an autosomal recessive condition; used to calculate probability and counsel families about recurrence risk
What each part means
25% affected = receives 2 defective genes (homozygous); 50% carrier = receives 1 defective gene (heterozygous, like the parents); 25% unaffected = receives 2 normal genes; applies per pregnancy independently
X-linked Recessive Inheritance: Carrier mother (X^c X) × Normal father (X Y) → 50% of SONS affected; 50% of DAUGHTERS are carriers
Mnemonic
The 'Mother's Hidden X' formula: Mom has one bad X hidden (carrier). She passes it to 50% of sons (who then have XcY = affected) and 50% of daughters (who become carriers). The father's Y has no X to mask the bad gene. Summary: 'Sons flip a coin — heads they're sick, tails they're fine. Daughters flip a coin — heads they're carriers, tails they're clear.' Apply to hemophilia A/B, G6PD, Duchenne MD.
When to use
Any question about X-linked recessive inheritance patterns, family counselling for hemophilia carriers, or questions about which offspring are at risk
What each part means
X^c = X chromosome carrying the defective gene; X = normal X chromosome; Y = Y chromosome (no corresponding gene to mask defect); 50% sons affected because they inherit X^c Y; 50% daughters carriers because they inherit X^c X

Without looking, list the 6 components of sickle cell crisis management in order. What is the most important nursing action to AVOID (cold)? What drug class is used for severe pain?
Memory chain
Picture a hip-hop DJ (HHOP) at a sickle cell crisis concert: he POURS WATER on the crowd first (Hydration — always first), then turns on the HEAT LIGHTS (Heat — never cold lights!), hands out OXYGEN BALLOON party favors (Oxygen), passes out PAIN MED goodie bags (Pain control), tells everyone to SIT AND REST (Rest), and then checks who started the crisis by calling the INFECTION SECURITY TEAM (treat the trigger). The concert ends only when the crisis is resolved.
Items to remember
- Hydration (IV or oral fluids — priority)
- Heat/Warmth (warm compresses — NEVER cold)
- Oxygen (correct hypoxia)
- Pain control (opioids for severe pain, assess pain scale)
- Rest (reduce oxygen demand)
- Treat underlying trigger (infection, dehydration)
Neutropenic Precautions — FRIEND Mnemonic (6 Key Rules)
Recall test
Name all 6 items on the neutropenic precautions FRIEND list. What is the single most important sign the nurse must treat as an emergency in a neutropenic child?
Memory chain
The hospital room has a FRIEND DO NOT ENTER sign on the door. The six banned FRIENDS are: Fresh Flower Fred (F), Raw Sushi Rita (R), IM Injection Ivan (I), Every Rectal-Temp Edgar (E), Noisy Crowd Nancy (N), and Drug-Dealer Dan with the Live Vaccine (D). Each friend tries to enter but the nurse stops them at the door. Fever from outside the door = CODE RED — call the doctor immediately!
Items to remember
- Flowers/plants — NO fresh flowers or plants in the room
- Raw food — NO raw/uncooked food (neutropenic diet)
- IM injections — avoid IM route
- Every rectal temperature/suppository — AVOID
- No crowds — no sick visitors, no crowds
- Do not give live vaccines during immunosuppression
Philippine Newborn Screening (RA 9288) — CHEE-PAKIG 5 Conditions
Recall test
Without looking, name all 5 conditions screened in the Philippine NBS program. What is the optimal timing for the heel prick? Which law mandates it?
Memory chain
A Filipino midwife shouts 'CHEE-PAKIG!' as she performs the heel prick on a newborn at 48 hours after feeding. Each letter of her shout = a condition: CH (Congenital Hypothyroidism — thyroid failure), P (PKU — phenylalanine builds up), K (CAH — cortisol/kortisel crisis), G (Galactosemia — milk sugar toxic), G6PD (enzyme deficiency — oxidant triggers hemolysis). The shout reminds her to prick AFTER FEEDING, AFTER 24 HOURS, and to label the filter paper card correctly per DOH protocol.
Items to remember
- Congenital Hypothyroidism (CH)
- Phenylketonuria (PKU = P)
- Congenital Adrenal Hyperplasia (CAH = K for Kortisel)
- Galactosemia (G)
- G6PD Deficiency (G6PD)
Inheritance Pattern Classification — 3 Categories with Examples
Recall test
Classify each: sickle cell disease, hemophilia A, G6PD deficiency, Down syndrome, thalassemia, Duchenne MD, PKU. State the recurrence risk for each category.
Memory chain
Three students in genetics class cheat differently. Student AR (Autosomal Recessive) hides cheat sheets in BOTH pockets (both parents must carry): her examples are 'STPGC' (Sickle, Thal, PKU, Galactosemia, CF). Student XL (X-linked) hides cheats in mom's bra (the X chromosome carried by mother): her examples are 'HHGD' (Hemo A, Hemo B, G6PD, Duchenne). Student CHROM (Chromosomal) accidentally printed an EXTRA exam paper (Trisomy = extra chromosome 21): always caused by a printing error, risk increases with the older the printer (advanced maternal age).
Items to remember
- Autosomal Recessive: Sickle Cell, Thalassemia, PKU, Galactosemia, Cystic Fibrosis (STPGC)
- X-linked Recessive: Hemophilia A, Hemophilia B, G6PD, Duchenne MD (HHGD)
- Chromosomal/Numerical: Down Syndrome Trisomy 21, advanced maternal age risk
Hemophilia Assessment & Management Chain
Recall test
In order: What is the hallmark sign of hemophilia? Which factor is deficient in the most common type? What lab is abnormal? What is the acute management acronym? Name 3 things to avoid.
Memory chain
Picture a BOY (X-linked, affects males) named Augustus (A = Factor VIII = most common) who has a CHRISTMAS Day injury (Hemophilia B = Christmas disease = Factor IX). His KNEES swell up (hemarthrosis = hallmark). The lab report says 'PTT TOO LONG, platelets fine' (PTT prolonged, platelets normal). The nurse gives him RICE at Christmas dinner (RICE = Rest, Ice, Compression, Elevation) and his Factor replacement injection. But she REMOVES the aspirin from the table (no aspirin/NSAIDs) and cancels his basketball game (no contact sports).
Items to remember
- X-linked recessive — affects males
- Hemophilia A = Factor VIII deficiency (most common, 80-85%)
- Hemophilia B = Factor IX deficiency (Christmas disease)
- Hallmark sign = hemarthrosis (joint bleeding)
- Lab: prolonged PTT; normal platelet count and bleeding time
- Acute bleed treatment = RICE + Factor replacement
- Avoid: aspirin/NSAIDs, IM injections, contact sports
