NLE Paediatric Nursing — Paediatric Hematologic, Oncologic & Genetic DisordersExam Answer Templates

Examiner tip

Examiners specifically test whether you know that ALL — not just 'leukemia' — is the most common type. Always include the full name and abbreviation for a guaranteed mark.

Model answer

Acute Lymphoblastic Leukemia (ALL) is the most common type of childhood cancer, with a peak incidence at 2–5 years of age.

Answer structure

• State the full name and abbreviation: Acute Lymphoblastic Leukemia (ALL) [1 mark]

Scoring breakdown

Common mark deductions

• Writing only 'leukemia' without specifying ALL — too vague
• Writing 'Acute Myeloid Leukemia (AML)' — incorrect type
• No marks for 'lymphoma' or any other cancer type

Key phrases to include

• Acute Lymphoblastic Leukemia
• ALL
• most common
• childhood cancer
• 2–5 years

Examiner tip

The word 'pancytopenia' is a high-yield term — using it signals clinical accuracy. Always follow it immediately with the three specific deficits.

Model answer

Bone marrow crowding in leukemia causes pancytopenia: anemia (low RBCs → pallor, fatigue), neutropenia (low WBCs → infection), and thrombocytopenia (low platelets → bleeding/petechiae).

Answer structure

• Name the three cell-line deficits: anemia, neutropenia, thrombocytopenia [1 mark — all three required]

Scoring breakdown

Common mark deductions

• Listing only two of the three components — no mark awarded if incomplete
• Writing 'low blood count' instead of the specific terms
• Confusing neutropenia with general leukopenia without specifying neutrophils

Key phrases to include

• pancytopenia
• anemia
• neutropenia
• thrombocytopenia
• bone marrow crowding

Examiner tip

A simple memory trick: 'A comes before B, and 8 comes before 9' — Hemophilia A = Factor VIII, Hemophilia B = Factor IX. Examiners commonly use this as a 2-mark compare-and-contrast question.

Model answer

Both Hemophilia A and Hemophilia B are X-linked recessive bleeding disorders that affect males. Hemophilia A is caused by a deficiency of Factor VIII and is the most common form, accounting for approximately 80–85% of cases. Hemophilia B (also called Christmas disease) is caused by a deficiency of Factor IX.

Answer structure

• Point 1: Hemophilia A = Factor VIII deficiency, most common (~80–85%) [1 mark]
• Point 2: Hemophilia B = Factor IX deficiency, also called Christmas disease [1 mark]

Scoring breakdown

Common mark deductions

• Reversing the factors — writing Factor IX for Hemophilia A is a critical error
• Omitting the inheritance pattern (X-linked recessive)
• Failing to state that Hemophilia A is more common

Key phrases to include

• Factor VIII
• Factor IX
• X-linked recessive
• Christmas disease
• most common
• 80–85%

Examiner tip

Examiners love mechanism-based teaching questions. You earn marks not for what to do, but for explaining WHY. Always include the biochemical reason, even briefly.

Model answer

Iron is best absorbed in an acidic environment. Vitamin C (ascorbic acid) in orange juice converts ferric iron (Fe³⁺) to ferrous iron (Fe²⁺), the form more easily absorbed in the duodenum, thereby enhancing absorption. Milk, on the other hand, contains calcium and casein protein, which bind to iron and form insoluble complexes that block absorption in the gastrointestinal tract. Therefore, giving iron WITH orange juice maximizes the therapeutic dose, while giving it WITH milk significantly reduces the amount of iron the child actually absorbs.

Answer structure

• Point 1: Explain WHY vitamin C (orange juice) enhances absorption — converts Fe³⁺ to Fe²⁺ in an acidic environment [1 mark]
• Point 2: Explain WHY milk impairs absorption — calcium and casein bind iron and block GI absorption [1 mark]

Scoring breakdown

Common mark deductions

• Saying only 'milk is bad for iron' without explaining the mechanism (no mark for vague answers)
• Omitting the role of Vitamin C as an absorption enhancer
• Reversing the explanation — stating milk enhances and juice impairs

Key phrases to include

• Vitamin C
• ascorbic acid
• enhances absorption
• acidic environment
• calcium in milk impairs absorption
• ferrous iron
• Fe²⁺

Examiner tip

For 3-mark questions requiring interventions with rationale, use a numbered list. One intervention + one rationale = one mark unit. Examiners scan for this one-to-one pairing.

Model answer

The following are three priority nursing interventions for a neutropenic child:

1. Enforce strict hand hygiene and place the child in a private room (protective/reverse isolation). RATIONALE: Neutropenic children lack adequate WBCs to fight infection; the primary mode of transmission is contact, and hand hygiene is the single most effective measure to prevent healthcare-associated infection.
2. Restrict fresh flowers, plants, raw/uncooked foods, and visits from sick individuals. RATIONALE: Fresh flowers and plants harbor Pseudomonas and mold spores; raw foods may carry Salmonella and E. coli; these are highly dangerous sources of infection when the child has no neutrophil defense.
3. Monitor temperature every 4 hours and treat any fever (≥38°C / 100.4°F) as a medical emergency — notify the physician immediately. RATIONALE: In a neutropenic child, fever is often the ONLY early sign of a life-threatening infection; rapid escalation to sepsis can occur without the typical inflammatory signs, making prompt reporting critical.

Answer structure

• Intervention 1 + Rationale: Hand hygiene and protective isolation [1 mark]
• Intervention 2 + Rationale: Restrict fresh flowers, plants, raw foods, sick visitors [1 mark]
• Intervention 3 + Rationale: Fever monitoring and emergency reporting [1 mark]

Scoring breakdown

Common mark deductions

• Listing interventions without rationale — rationale is explicitly requested and earns the mark
• Vague intervention: 'avoid infection' without specifying how
• Including 'take rectal temperature' — this is actually CONTRAINDICATED in neutropenic patients and would indicate a knowledge deficit

Key phrases to include

• neutropenic precautions
• protective/reverse isolation
• hand hygiene
• no fresh flowers or plants
• no raw/uncooked foods
• fever = emergency
• only early sign of infection
• private room

Examiner tip

The mnemonic HHOP (Hydration, Heat, Oxygen, Pain) is a high-yield answer organizer. Writing it clearly at the start of your answer signals to the examiner that you have an organized, complete response.

Model answer

The priority management during a vaso-occlusive crisis in Sickle Cell Disease follows the mnemonic HHOP:

1. Hydration: Administer IV and/or oral fluids aggressively (1.5–2× maintenance rate). Adequate hydration reduces blood viscosity and flushes sickled cells from occluded vessels.
2. Heat: Apply warm compresses to affected joints and keep the child warm. NEVER apply cold/ice — vasoconstriction from cold promotes further sickling and worsens the crisis.
3. Oxygen: Administer supplemental oxygen as ordered to correct hypoxia, which is the primary trigger for sickling. Monitor SpO₂.
4. Pain control: Administer analgesics as ordered — opioids (e.g., morphine) are appropriate for severe vaso-occlusive pain. Assess pain using an age-appropriate scale (FLACC, Wong-Baker FACES). Rest and comfortable positioning also reduce oxygen demand.

Answer structure

• H — Hydration: IV fluids, rationale for reducing viscosity [~0.75 mark]
• H — Heat (never cold): warm compresses, rationale for avoiding vasoconstriction [~0.75 mark]
• O — Oxygen: supplemental O₂ to correct hypoxia [~0.75 mark]
• P — Pain control: opioid analgesics, pain assessment scale [~0.75 mark]
• (Full 3 marks for addressing all four HHOP components with rationale)

Scoring breakdown

Common mark deductions

• Recommending cold/ice packs — this is a critical safety error that examiners penalize
• Omitting the rationale for avoiding cold (vasoconstriction worsens sickling)
• Only listing pain management and missing hydration and oxygen — incomplete answer

Key phrases to include

• HHOP
• hydration
• IV fluids
• warm compresses
• never cold
• supplemental oxygen
• hypoxia
• opioid analgesics
• pain assessment
• vaso-occlusive crisis

Examiner tip

This is a classic NLE trick question — thalassemia sounds like an anemia that needs iron, but the opposite is true. Students who write 'give ferrous sulfate' lose marks. The correct answer is always chelation.

Model answer

Children with thalassemia major (Cooley's anemia) require regular, lifelong blood transfusions to maintain adequate hemoglobin levels. However, each transfusion introduces additional iron that the body cannot excrete naturally. Over time, this iron accumulates in vital organs — particularly the heart, liver, and endocrine glands — causing hemosiderosis (iron overload), which leads to cardiac failure, hepatic cirrhosis, and endocrine dysfunction (e.g., diabetes, growth failure). Management involves chelation therapy: deferoxamine (given parenterally/subcutaneously via an infusion pump) or deferasirox (oral tablet), which bind excess iron and allow it to be excreted through urine and feces.

Answer structure

• Point 1: Explain why iron overload occurs (repeated transfusions → iron accumulates → organ damage: heart, liver, endocrine) [1 mark]
• Point 2: State the management — chelation therapy: deferoxamine (parenteral) or deferasirox (oral) [1 mark]

Scoring breakdown

Common mark deductions

• Stating 'give iron supplements' — this is the OPPOSITE of correct management for thalassemia major
• Naming the drugs without explaining that they work by binding and excreting excess iron
• Confusing iron supplementation (for IDA) with iron chelation (for thalassemia)

Key phrases to include

• hemosiderosis
• iron overload
• repeated blood transfusions
• chelation therapy
• deferoxamine
• deferasirox
• cardiac failure
• hepatic damage

Examiner tip

Use precise anatomical terms. 'Upward-slanting palpebral fissures' earns a mark; 'slanted eyes' may not. Examiners look for clinical vocabulary.

Model answer

During newborn assessment, a nurse would observe the following classic features of Down Syndrome (Trisomy 21):

1. Hypotonia (generalized muscle floppiness — the infant feels limp when held)
2. Upward-slanting palpebral fissures with epicanthal folds (inner eye skin folds)
3. Single transverse palmar crease (simian crease — one horizontal line across the entire palm instead of two)
4. Protruding tongue with small oral cavity (macroglossia relative to the small mouth)

Additional features include a flat facial profile, short neck, flat nasal bridge, and a wide gap between the first and second toes.

Answer structure

• Feature 1: Hypotonia [0.5 mark]
• Feature 2: Upslanting palpebral fissures with epicanthal folds [0.5 mark]
• Feature 3: Single transverse palmar (simian) crease [0.5 mark]
• Feature 4: Protruding tongue / small oral cavity [0.5 mark]

Scoring breakdown

Common mark deductions

• Vague descriptions like 'different looking eyes' without naming the feature properly
• Listing associated conditions (e.g., congenital heart defect) instead of physical features
• Writing fewer than four features when four are requested

Key phrases to include

• hypotonia
• upward-slanting palpebral fissures
• epicanthal folds
• single transverse palmar crease
• simian crease
• protruding tongue
• flat facial profile
• Trisomy 21

Examiner tip

Case study questions on hemophilia almost always test RICE + Factor replacement. If you write RICE but forget Factor VIII, you lose the most important mark. Always end with the definitive intervention.

Model answer

For an acute hemarthrosis in a child with Hemophilia A, the immediate nursing interventions follow the RICE protocol plus factor replacement:

1. Rest: Immobilize and rest the affected right knee joint immediately to prevent further bleeding. Assist the child to a comfortable position; do NOT bear weight on the joint.
2. Ice: Apply a cold pack/ice wrapped in cloth to the joint for 20 minutes. Ice causes vasoconstriction, slowing blood flow into the joint space and reducing swelling.
3. Compression: Apply a gentle elastic bandage to compress the joint and limit the extent of hemorrhage.
4. Elevation: Elevate the right leg above heart level to reduce hydrostatic pressure and minimize further bleeding.
5. Factor replacement: Collaborate with the physician to prepare and administer Factor VIII concentrate as prescribed — this is the definitive treatment to stop the bleeding. Monitor for allergic/adverse reactions during infusion.

Answer structure

• Step 1: Rest and immobilization of the joint [0.5 mark]
• Step 2: Ice application (vasoconstriction) [0.5 mark]
• Step 3: Compression bandage [0.5 mark]
• Step 4: Elevation above heart level [0.5 mark]
• Step 5: Factor VIII replacement — definitive treatment [1 mark]

Scoring breakdown

Common mark deductions

• Recommending aspirin or NSAIDs for pain — these are CONTRAINDICATED in hemophilia as they impair platelet function
• Not mentioning factor replacement — RICE alone is supportive, not definitive
• Recommending heat instead of ice — heat promotes vasodilation and worsens bleeding

Key phrases to include

• RICE
• rest
• immobilize
• ice pack
• vasoconstriction
• compression
• elevation
• Factor VIII concentrate
• definitive treatment
• hemarthrosis

Examiner tip

Philippine nursing exams frequently combine clinical knowledge with RA citations. RA 9288 is to newborn screening what RA 9173 is to nursing practice — know it by number. Always include the law number for Philippine-specific questions.

Model answer

The Philippine Newborn Screening Program is mandated by Republic Act 9288 (Newborn Screening Act of 2004). It requires that ALL newborns be screened via a heel-prick blood sample, ideally collected 24–72 hours after birth (after the baby has been fed for at least 24 hours to ensure metabolites are detectable). The rationale is that early detection and treatment of specific inborn errors of metabolism and endocrine disorders can prevent irreversible intellectual disability, developmental delay, or death.

Three conditions screened:

1. Congenital Hypothyroidism (CH): Deficiency of thyroid hormone from birth causes cretinism (intellectual disability, growth failure) if untreated. Early thyroxine replacement prevents permanent disability.
2. Phenylketonuria (PKU): Autosomal recessive defect in phenylalanine hydroxylase → phenylalanine accumulates → brain damage. Management: lifelong low-phenylalanine diet; avoid aspartame.
3. G6PD Deficiency: X-linked recessive enzyme defect → hemolysis when exposed to oxidative stressors (fava beans, naphthalene/mothballs, sulfa drugs, antimalarials). Early identification allows parents to avoid triggers.

Answer structure

• Introduction: State RA 9288, timing (24–72 h after birth, after feeding), and general rationale for screening [1 mark]
• Condition 1 (e.g., Congenital Hypothyroidism) with brief consequence and management [0.67 mark]
• Condition 2 (e.g., PKU) with inheritance and management [0.67 mark]
• Condition 3 (e.g., G6PD) with inheritance, trigger avoidance [0.66 mark]

Scoring breakdown

Common mark deductions

• Not citing RA 9288 — the Philippine legal context is worth marks
• Stating screening is done at birth (Day 0) — incorrect; it must be AFTER feeding, ideally 24–72 hours
• Listing conditions without explaining what happens if undetected (missing the rationale for why early screening matters)

Key phrases to include

• RA 9288
• Newborn Screening Act
• heel-prick
• 24–72 hours after birth
• congenital hypothyroidism
• PKU
• G6PD deficiency
• galactosemia
• congenital adrenal hyperplasia
• prevent intellectual disability

Examiner tip

Philippine NLE frequently tests NANDA three-part nursing diagnosis format. Memorize: [Nursing Diagnosis] + related to [etiology/RF] + as evidenced by [signs/symptoms/AMB]. Never use a medical diagnosis in the first part.

Model answer

Priority Nursing Diagnosis (NANDA format):
'Risk for Bleeding related to decreased platelet count (thrombocytopenia) secondary to immune-mediated platelet destruction, as evidenced by petechiae, purpura, and easy bruising.'

Justification (Maslow's Hierarchy):
This is the priority nursing diagnosis because it addresses a physiologic safety need — the prevention of serious hemorrhage, including potentially life-threatening intracranial bleeding. According to Maslow's Hierarchy of Needs, physiologic and safety needs (Levels 1 and 2) always take precedence over psychosocial needs. In ITP, the platelet count may fall below 10,000/mm³, placing the child at imminent risk for spontaneous bleeding; therefore, this risk takes priority over nursing diagnoses related to anxiety or knowledge deficit.

Answer structure

• State the NANDA nursing diagnosis with the three-part format: Diagnosis + related to (RF) + as evidenced by (AMB) [1 mark]
• Justify priority using Maslow — physiologic/safety need over psychosocial needs [1 mark]

Scoring breakdown

Common mark deductions

• Writing the nursing diagnosis without 'related to' and 'as evidenced by' — incomplete NANDA format loses the mark
• Prioritizing 'Anxiety' or 'Deficient Knowledge' over bleeding risk — incorrect Maslow application
• Writing 'Hemorrhage' as a nursing diagnosis — this is a medical diagnosis, not a NANDA nursing diagnosis

Key phrases to include

• Risk for Bleeding
• thrombocytopenia
• immune-mediated platelet destruction
• petechiae
• purpura
• Maslow's Hierarchy
• physiologic safety need
• intracranial bleeding
• NANDA

Examiner tip

For a 5-mark long answer, use clear Roman numeral or lettered headings — Assessment, Nursing Diagnoses, Interventions, Teaching, Evaluation. Examiners use these headings as a marking checklist. A well-organized answer signals clinical competence even before the content is read. Aim for at least one full page of relevant, specific content.

Model answer

COMPREHENSIVE NURSING CARE: 4-Year-Old with Acute Lymphoblastic Leukemia (ALL) Beginning Chemotherapy

I. ASSESSMENT (Data Collection)
Subjective data: Parents report fatigue, bone pain, decreased appetite, and frequent bruising. The child complains of joint pain.
Objective data: Pallor, petechiae, hepatosplenomegaly, lymphadenopathy, low-grade fever. Laboratory: pancytopenia — low RBCs (anemia), low ANC (neutropenia), low platelet count (thrombocytopenia). Diagnosis confirmed by bone marrow aspiration showing >25% blast cells.

II. PRIORITY NURSING DIAGNOSES (Maslow-Based)

1. Risk for Infection related to neutropenia secondary to leukemic bone marrow infiltration — HIGHEST PRIORITY (infection is the leading cause of death in ALL).
2. Risk for Bleeding related to thrombocytopenia secondary to bone marrow suppression.
3. Imbalanced Nutrition: Less than Body Requirements related to nausea, vomiting, and mucositis secondary to chemotherapy.
4. Acute Pain related to bone marrow infiltration and chemotherapy side effects.
5. Anxiety (Child and Family) related to new diagnosis of leukemia and unfamiliar treatment.

III. KEY NURSING INTERVENTIONS
A. Infection Prevention (Priority):

• Institute neutropenic precautions: place in private room; enforce strict hand hygiene for all contacts; restrict fresh flowers, plants, and raw/uncooked foods; prohibit visits from sick individuals.
• Monitor temperature every 4 hours — report any temperature ≥38°C (100.4°F) immediately to the physician (fever = medical emergency in neutropenia).
• Avoid rectal temperatures, rectal suppositories, and IM injections to prevent introduction of organisms and hematoma.
• Administer prescribed antibiotics promptly if infection is suspected.
• Live vaccines are CONTRAINDICATED during chemotherapy.

B. Bleeding Precautions:

• Use a soft toothbrush and gentle oral care; avoid flossing if platelets <50,000/mm³.
• Avoid aspirin and NSAIDs (impair platelet function).
• Apply pressure to venipuncture sites for at least 5 minutes.
• Monitor platelet counts; prepare for platelet transfusion if ordered.
• Prevent falls and injury; pad side rails if the child is restless.

C. Chemotherapy Side Effect Management:

• Nausea/Vomiting: Administer prescribed antiemetics (e.g., ondansetron) 30–60 minutes BEFORE chemotherapy; offer small, frequent bland meals.
• Mucositis: Perform mouth care every 4 hours with normal saline rinse; use soft-bristled toothbrush; avoid alcohol-based commercial mouthwash; serve soft, non-acidic foods; assess for oral candidiasis (give antifungals as ordered).
• Alopecia: Prepare the child and family — reassure that hair loss is temporary and regrowth occurs after therapy ends; consider soft head coverings.
• Constipation from vincristine: Monitor bowel movements; encourage fluid intake and age-appropriate activity; administer stool softeners as ordered.

D. Pain Management:

• Assess pain using the Wong-Baker FACES scale or FLACC scale appropriate for the child's age and developmental level.
• Administer analgesics as prescribed; use non-pharmacologic pain management (distraction, positioning, guided imagery).
• Encourage age-appropriate play and therapeutic activities.

IV. FAMILY TEACHING

• Educate parents about neutropenic precautions at home: hand hygiene, food safety (no raw foods), avoidance of crowds and sick contacts, and when to seek emergency care (fever ≥38°C, unusual bleeding, extreme pallor, or difficulty breathing).
• Teach the importance of not giving any over-the-counter medications (especially aspirin, ibuprofen, or products containing aspirin) without physician approval.
• Explain the chemotherapy schedule and expected side effects; reassure that side effects such as hair loss are temporary.
• Provide emotional support; refer to the Child Life Specialist and social worker; connect the family with support groups available in Philippine Cancer Society and Philippine Children's Medical Center resources.
• Stress the importance of follow-up blood counts (CBC monitoring) and not missing chemotherapy schedules.

V. EVALUATION

• The child remains free from signs and symptoms of infection (afebrile, no new lesions) throughout hospitalization.
• No episodes of significant bleeding occur (platelet count maintained within safe parameters).
• The child tolerates chemotherapy with managed nausea; maintains at least 75% of recommended daily caloric intake.
• Parents verbalize understanding of neutropenic precautions, when to call the physician, and how to administer oral medications safely at home.
• Pain is rated ≤3/10 on the Wong-Baker FACES scale.

Answer structure

• Section I — Assessment: Subjective + Objective data including lab findings (pancytopenia, bone marrow aspiration) [1 mark]
• Section II — Priority Nursing Diagnoses: At least 2 in NANDA format, Maslow-prioritized, with 'Risk for Infection' as #1 [1 mark]
• Section III — Interventions: Neutropenic precautions + bleeding precautions + chemo side effect management (at least 6 specific interventions) [1.5 marks]
• Section IV — Family Teaching: At least 3 specific teaching points with rationale [1 mark]
• Section V — Evaluation: At least 2 measurable outcome statements [0.5 mark]

Scoring breakdown

Common mark deductions

• Writing nursing diagnoses in medical terminology (e.g., 'Leukemia' or 'Pancytopenia') — NANDA format required
• Missing the nursing priority rationale — stating 'Risk for Infection' as #1 without explaining that infection is the leading cause of death loses marks
• Generic interventions ('monitor the patient,' 'maintain safety') without specificity
• Omitting evaluation — the Nursing Process has 5 steps; missing step 5 loses marks in a 5-mark question
• Recommending live vaccines during chemotherapy — this is a critical safety error

Key phrases to include

• pancytopenia
• neutropenic precautions
• Risk for Infection — leading cause of death
• no fresh flowers/raw food
• fever = emergency
• no rectal temps
• live vaccines contraindicated
• antiemetics before chemo
• Wong-Baker FACES
• NANDA format
• Maslow prioritization
• bone marrow aspiration
• bleeding precautions
• soft toothbrush
• no aspirin/NSAIDs

Examiner tip

Inheritance pattern questions are almost always 2–3 marks. Include: (1) the pattern name, (2) who is affected and who is a carrier, (3) the percentage risk per pregnancy, and (4) at least one counselling point. This four-part structure maps perfectly to the mark breakdown.

Model answer

Hemophilia A and Sickle Cell Disease differ significantly in their inheritance patterns, which has important implications for genetic counselling:

1. Hemophilia A — X-Linked Recessive:

• The defective gene is carried on the X chromosome. Since males have only one X chromosome (XY), a single defective copy causes disease. Females (XX) are typically carriers with one normal and one defective X chromosome.
• Pattern: Carrier mother × unaffected father → 50% of sons affected, 50% of daughters are carriers.
• Counselling implication: Male children of carrier mothers have a 50% risk of being affected. Female children will not usually show disease but may be carriers. Prenatal testing (amniocentesis, CVS) is available. Carrier daughters should also be counselled about their risk of having affected sons.

2. Sickle Cell Disease — Autosomal Recessive:

• The defective HbS gene is carried on an autosome (not sex-linked); both parents must carry the sickle cell trait (HbAS) for a child to be affected (HbSS).
• Pattern: Two carrier parents (trait) × trait → 25% affected (HbSS), 50% carriers (HbAS), 25% normal (HbAA) each pregnancy.
• Counselling implication: Both parents must be carriers; neither parent shows disease (they have sickle cell trait). Each pregnancy carries a 25% (1 in 4) risk of an affected child, regardless of previous outcomes. Genetic counselling is non-directive; the nurse provides information without imposing a decision.

Answer structure

• Hemophilia A: State X-linked recessive, explain mother is carrier, sons are affected; counselling implications [1 mark]
• Sickle Cell Disease: State autosomal recessive, both parents carriers, 25% risk per pregnancy; counselling implications [1 mark]
• Key difference highlighted: sex-linked vs. autosomal; nurse's non-directive counselling role [1 mark]

Scoring breakdown

Common mark deductions

• Stating that carrier females with Hemophilia A are 'affected' — they are carriers, not typically affected
• Stating the sickle cell risk as '50%' instead of '25%' for an affected child
• Omitting the counselling implication — the question explicitly asks for both inheritance AND counselling

Key phrases to include

• X-linked recessive
• autosomal recessive
• carrier mother
• 50% of sons affected
• both parents carriers
• 25% risk per pregnancy
• non-directive counselling
• HbAS
• HbSS

Examiner tip

Patient teaching questions for iron always test four things: timing (empty stomach), enhancer (Vitamin C), inhibitor (milk), and safety (toxicity/lock away). Cover all four and you guarantee full marks.

Model answer

Complete Patient Teaching for Iron Drops (Ferrous Sulfate) at Home:

1. How to give the drops for best absorption:

• Give the iron drops between meals or on an empty stomach — this maximizes absorption in the gastrointestinal tract.
• Always give with Vitamin C (e.g., a few drops of orange juice) — Vitamin C enhances iron absorption by keeping iron in the ferrous (Fe²⁺) form.
• Do NOT give with milk, formula, or dairy — calcium in milk blocks iron absorption. Space iron doses at least 1–2 hours away from milk feeding.

2. How to give the drops safely:

• Use the dropper to place the liquid iron toward the back of the mouth or along the inner cheek — this prevents the drops from staining the baby's teeth brown.
• Wipe or rinse the child's teeth and gums gently after each dose.

3. Expected side effects — what is normal:

• The infant's stools will become dark green, tarry, or black — this is NORMAL and expected. Do not be alarmed.
• Mild constipation or stomach upset may occur; offer extra fluids and, if tolerated, dietary fiber.

4. SAFETY WARNING — the most important teaching point:

• Keep all iron preparations LOCKED AWAY and completely out of the child's reach at all times. Accidental ingestion of iron is a leading cause of poisoning death in young children in the Philippines. Even a small number of iron tablets or drops can be fatal if swallowed by a toddler.

Answer structure

• Teaching Point 1: Administration for best absorption — empty stomach, with Vitamin C, NOT with milk [1 mark]
• Teaching Point 2: Use a straw/dropper to prevent tooth staining; oral hygiene after dose [0.5 mark]
• Teaching Point 3: Expected normal side effects — dark/tarry stools, possible constipation [0.5 mark]
• Teaching Point 4: SAFETY — lock iron away; iron overdose is a leading cause of child poisoning death [1 mark]

Scoring breakdown

Common mark deductions

• Recommending giving iron WITH milk — critical error; loses the absorption mark
• Stating that dark stools are a sign of internal bleeding requiring emergency care — this is INCORRECT; dark stools from iron are expected
• Omitting the safety/poisoning teaching — this is consistently tested because it is a life-safety issue

Key phrases to include

• empty stomach
• Vitamin C / orange juice
• NOT with milk
• tooth staining
• dropper toward the back of the mouth
• dark/tarry stools — normal
• constipation
• lock iron away
• poisoning death
• leading cause of child poisoning

Examiner tip

The aspartame teaching point is the 'surprise' mark in PKU questions — many students know the low-phenylalanine diet but forget that aspartame (phenylalanine-containing artificial sweetener) is found in diet drinks and medicines. This point consistently separates high scorers from average scorers.

Model answer

Pathophysiology of PKU:
Phenylketonuria (PKU) is an autosomal recessive inborn error of metabolism. The child is born with a deficiency of the enzyme phenylalanine hydroxylase, which is responsible for converting the amino acid phenylalanine into tyrosine. Without this enzyme, phenylalanine accumulates in the blood and brain tissue, where it is toxic to developing neurons. The result, if untreated, is progressive and irreversible intellectual disability, seizures, and behavioral problems. PKU is detected through the Philippine Newborn Screening Program (RA 9288) via heel-prick blood testing done 24–72 hours after birth.

Dietary Management Teaching:

1. Lifelong low-phenylalanine diet: Strictly restrict all high-protein foods, as protein is the main dietary source of phenylalanine. Avoid: meat, poultry, fish, eggs, dairy products, regular infant formula, nuts, and legumes.
2. Use PKU special formula: Provide a special low-phenylalanine medical formula that supplies all essential amino acids (except phenylalanine) needed for normal growth and development.
3. Avoid aspartame: The artificial sweetener aspartame (found in diet sodas, sugar-free products, and some medicines) is converted to phenylalanine in the body and is strictly CONTRAINDICATED.
4. Allowed foods: Fruits, most vegetables, and specially formulated low-protein breads/pastas in controlled amounts.
5. Monitoring: Regular blood phenylalanine levels must be checked to ensure levels remain within the safe target range (2–6 mg/dL). Dietary management must continue for life — it is NOT something the child will outgrow.

Answer structure

• Pathophysiology: Autosomal recessive; phenylalanine hydroxylase deficiency → phenylalanine accumulation → brain damage/intellectual disability; detected by NBS (RA 9288) [1 mark]
• Diet Teaching Point 1: Lifelong low-phenylalanine diet — restrict high-protein foods; use special PKU formula [1 mark]
• Diet Teaching Point 2: Avoid aspartame; allowed foods; monitor blood phenylalanine levels for life [1 mark]

Scoring breakdown

Common mark deductions

• Confusing PKU with galactosemia or hypothyroidism (different NBS conditions)
• Stating the diet is only needed in infancy — PKU dietary restrictions are LIFELONG
• Not mentioning aspartame avoidance — this is a high-yield, often-tested teaching point

Key phrases to include

• phenylalanine hydroxylase deficiency
• phenylalanine accumulates
• intellectual disability
• autosomal recessive
• RA 9288
• newborn screening
• lifelong low-phenylalanine diet
• special PKU formula
• avoid aspartame
• lifelong monitoring

Do

• State the answer immediately — no preamble or restating the question
• Use the full clinical term plus abbreviation on first mention (e.g., 'Acute Lymphoblastic Leukemia (ALL)')
• Include the key qualifier if it distinguishes your answer (e.g., 'MOST common,' 'X-linked recessive,' 'leading cause of death')
• Write in a complete sentence — fragments lose marks even if the fact is correct

Don't

• Do not write lengthy paragraphs — 1 mark = 1 line
• Do not use vague language ('it is a type of cancer') without specifics
• Do not spend more than 2 minutes on a 1-mark question
• Do not start with 'In my opinion' or 'I think' — state clinical facts directly

Do

• Use a numbered list (1. and 2.) to make the two mark-earning points obvious
• Include a brief rationale or mechanism for each point — do not just list bare facts
• Use precise vocabulary: inheritance pattern names, drug names, specific lab values
• Relate the answer to the nursing implication where relevant (e.g., 'therefore the nurse must...')

Don't

• Do not write one long paragraph with two points buried inside — they may not be found by the examiner
• Do not repeat the same point in different words thinking it earns two marks
• Do not include more than 3 points — quality and accuracy matter more than quantity at 2-mark level
• Do not leave out the drug name, inheritance pattern, or other key identifier if it is the core of the question

Do

• Begin with a one-sentence overview/definition before listing your 3 points
• Use a clear numbered or lettered structure (1., 2., 3. OR A., B., C.)
• Write Intervention → Rationale pairs for all nursing care questions
• Include at least one Philippine nursing context (RA 9173, RA 9288, PhilHealth, local resources) where relevant
• Include at least one NANDA nursing diagnosis in proper 3-part format if the question involves nursing care

Don't

• Do not simply list three items without any explanation — bare lists lose rationale marks
• Do not write 5 points hoping that 3 of them are correct — examiners grade the first 3 listed; extra points do not add marks
• Do not use vague actions ('ensure safety,' 'prevent infection') without specifics
• Do not recommend contraindicated interventions (aspirin in hemophilia, cold for sickle cell crisis, iron for thalassemia)

Do

• Use CLEAR SECTION HEADINGS: I. Assessment, II. Nursing Diagnoses, III. Interventions, IV. Teaching, V. Evaluation
• State the highest-priority nursing diagnosis FIRST with explicit Maslow justification
• List at least 4–6 specific nursing interventions with at least brief rationale for each
• Include family/patient teaching as a separate section — examiners look for it specifically
• End with measurable evaluation criteria using outcome language ('the patient will...' or 'the child will remain free from...')
• Use clinical values where relevant (e.g., 'temperature ≥38°C,' 'platelet count below 50,000/mm³')

Don't

• Do not write in a single unbroken block of text — structure is essential for 5-mark questions
• Do not skip the Evaluation section — the Nursing Process has 5 steps and examiners check all 5
• Do not use medical diagnoses in the Nursing Diagnosis section
• Do not forget to apply Philippine context for long answers (RA 9173, RA 9288, PCMC, DOH programs, PhilHealth coverage)
• Do not be repetitive — each section should add NEW information, not restate the previous one
