SECTION 1: BASIC WEIGHT-BASED DOSAGE CALCULATIONS — Questions 1–30
1. A pediatric patient weighing 22 kg is ordered to receive amoxicillin 40 mg/kg/day divided
into two doses. What is the individual dose?
A. 440 mg
B. 880 mg
C. 220 mg
D. 110 mg
CorreCt Answer: A
,Rationale: Daily dose = 40 mg/kg × 22 kg = 880 mg/day. Divided into two doses: 880 mg ÷ 2 =
440 mg per dose.
2. A child weighing 16 kg is prescribed cefdinir 14 mg/kg/day divided into two doses.
Calculate the amount per dose.
A. 112 mg
B. 224 mg
C. 56 mg
D. 100 mg
CorreCt Answer: A
Rationale: Daily dose = 14 mg/kg × 16 kg = 224 mg/day. Divided into two doses: 224 mg ÷ 2 =
112 mg per dose.
3. A pediatric patient weighs 34 kg and is ordered to receive ibuprofen 10 mg/kg/dose every 6
hours for fever. What is the maximum daily dose for this child?
,A. 340 mg
B. 680 mg
C. 1,020 mg
D. 1,360 mg
CorreCt Answer: D
Rationale: Each dose = 10 mg/kg × 34 kg = 340 mg. Every 6 hours = 4 doses/day. Daily dose =
340 mg × 4 = 1,360 mg/day. Note: Maximum daily ibuprofen dose is typically 40 mg/kg/day or
2,400 mg/day, whichever is lower.
4. A 5-year-old child weighing 18 kg is prescribed acetaminophen 15 mg/kg/dose every 4
hours for pain. What is the individual dose?
A. 180 mg
B. 270 mg
C. 300 mg
D. 360 mg
CorreCt Answer: B
, Rationale: Dose = 15 mg/kg × 18 kg = 270 mg per dose.
5. A child weighing 12 kg is ordered to receive ceftriaxone 50 mg/kg/day IV divided into two
doses. Calculate the volume needed if the concentration is 100 mg/mL.
A. 3 mL
B. 6 mL
C. 9 mL
D. 12 mL
CorreCt Answer: A
Rationale: Daily dose = 50 mg/kg × 12 kg = 600 mg/day. Per dose = 600 mg ÷ 2 = 300 mg.
Volume = 300 mg ÷ 100 mg/mL = 3 mL.
6. A pediatric patient weighing 8 kg is prescribed furosemide 1 mg/kg/dose IV every 12 hours.
The concentration is 10 mg/mL. Calculate the volume per dose.
A. 0.4 mL
B. 0.8 mL
