Practice Test — Complex Conditions, Clinical Assessment, Critical
Care, Nursing Interventions & Clinical Reasoning — 190 Multiple-
Choice Questions with Answers & Detailed Rationales
Domain 1: Pediatric Patient Population (52 Questions)
Question 1
A 3-day-old neonate born at 36 weeks gestation is receiving ampicillin for suspected sepsis.
The pharmacist notes the half-life is significantly prolonged compared to older infants.
Which developmental factor best explains this finding?
A. Decreased gastric pH
B. Immature glomerular filtration rate
C. Increased body fat percentage
D. Enhanced protein binding
Correct Answer: B
Explanation: Neonatal renal clearance is markedly reduced due to immature glomerular
filtration, prolonging elimination of renally excreted drugs like ampicillin. Clinical pearl:
Always adjust renally cleared medications in neonates until GFR matures.
Question 2
A 6-month-old infant requires maintenance fluids. Weight is 7.5 kg. Using the Holliday-Segar
method, what is the appropriate 24-hour fluid volume?
A. 625 mL
B. 700 mL
C. 750 mL
D. 875 mL
,Correct Answer: C
Explanation: Holliday-Segar: 100 mL/kg/day for first 10 kg. 7.5 × 100 = 750 mL/day. Clinical
pearl: Reassess electrolytes and urine output when calculating maintenance fluids.
Question 3
A 12-year-old with sickle cell disease presents for routine care. Which prophylactic
medication is standard to prevent invasive pneumococcal disease?
A. Amoxicillin
B. Penicillin V
C. Azithromycin
D. Cefdinir
Correct Answer: B
Explanation: Daily oral penicillin V prophylaxis is standard for children with sickle cell disease
until age 5 and beyond in some guidelines. Clinical pearl: Ensure immunizations are up to
date alongside prophylaxis.
Question 4
A 4-year-old child with severe egg allergy requires influenza vaccination. Which formulation
is contraindicated?
A. Inactivated trivalent influenza vaccine
B. Live attenuated intranasal influenza vaccine
C. Recombinant influenza vaccine
D. Adjuvanted influenza vaccine
Correct Answer: B
,Explanation: Live attenuated influenza vaccine is contraindicated in severe egg allergy due to
higher egg protein content. Clinical pearl: Inactivated vaccines may be given in healthcare
settings equipped for anaphylaxis.
Question 5
A 2-year-old presents with microcytic anemia. Laboratory results show low hemoglobin, low
MCV, and low ferritin. What is the most likely diagnosis?
A. Thalassemia trait
B. Iron deficiency anemia
C. Lead poisoning
D. Sideroblastic anemia
Correct Answer: B
Explanation: Low ferritin with microcytic anemia confirms iron deficiency in children. Clinical
pearl: Ferritin is an acute-phase reactant; interpret with CRP in inflammatory states.
Question 6
A 10-year-old requires a medication dosed by body surface area (BSA). Which formula is
most commonly used in pediatric pharmacy practice?
A. DuBois formula
B. Boyd formula
C. Mosteller formula
D. Haycock formula
Correct Answer: C
Explanation: Mosteller formula (√[height(cm) × weight(kg)/3600]) is simple, accurate, and
widely used in pediatrics. Clinical pearl: Verify BSA calculations independently when dosing
chemotherapy.
, Question 7
A 5-year-old with asthma uses a metered-dose inhaler. What delivery device is essential to
ensure adequate lung deposition?
A. Nebulizer mask
B. Spacer with mouthpiece
C. Dry powder inhaler
D. Nasal cannula
Correct Answer: B
Explanation: Spacers reduce oropharyngeal deposition and improve lower airway delivery in
young children. Clinical pearl: Teach and observe inhaler technique at every visit.
Question 8
A 14-year-old presents with acne. Which medication requires baseline and periodic lipid
monitoring?
A. Doxycycline
B. Isotretinoin
C. Benzoyl peroxide
D. Clindamycin topical
Correct Answer: B
Explanation: Isotretinoin causes hypertriglyceridemia and requires baseline and periodic
lipid panels. Clinical pearl: Also monitor liver function and ensure pregnancy prevention
compliance.
