Choice Questions Covering Weight-Based Dosing, Body Surface Area, Safe Dose Ranges, IV
Infusion Rates, and Critical Clinical Applications for Pediatric Healthcare Providers
SECTION 1: BASIC WEIGHT-BASED DOSAGE CALCULATIONS (Questions 1-40)
Question 1
A pediatric patient weighs 22 kg. The healthcare provider orders amoxicillin 40 mg/kg/day
divided into two doses. What is the amount of amoxicillin in milligrams that the patient will
receive per dose?
A) 440 mg per dose
B) 880 mg per dose
C) 220 mg per dose
D) 110 mg per dose
E) 500 mg per dose
,2
CorreCt Answer: A
Rationale: Calculate total daily dose: 40 mg/kg × 22 kg = 880 mg/day. Divide by 2 doses: 880 ÷ 2
= 440 mg per dose. Option B is the total daily dose. Option C results from using 20 mg/kg.
Option D results from dividing by 4 doses. Option E is an arbitrary value.
Question 2
A child weighing 16 kg is prescribed cefdinir 14 mg/kg/day divided into two doses. How many
milligrams should the nurse administer per dose?
A) 112 mg per dose
B) 224 mg per dose
C) 56 mg per dose
D) 28 mg per dose
E) 100 mg per dose
CorreCt Answer: A
,3
Rationale: Total daily dose = 14 mg/kg × 16 kg = 224 mg/day. Per dose = 224 ÷ 2 = 112 mg.
Option B is the total daily dose. Option C results from using 7 mg/kg. Option D results from
dividing by 4. Option E is an arbitrary value.
Question 3
A pediatric patient weighing 12 kg is ordered azithromycin 10 mg/kg once daily. What volume in
mL should be administered if the medication is available as 200 mg/5 mL?
A) 2 mL
B) 3 mL
C) 4 mL
D) 5 mL
E) 6 mL
CorreCt Answer: B
Rationale: Dose = 10 mg/kg × 12 kg = 120 mg. Use ratio: 200 mg/5 mL = 120 mg/x mL → x =
(120 × 5) ÷ 200 = 600 ÷ 200 = 3 mL. Option A results from using 80 mg. Option C results from
using 160 mg. Option D results from using 200 mg. Option E results from using 240 mg.

Question 4
A child weighing 8 kg is prescribed clindamycin 20 mg/kg/day in three divided doses. The
medication is available as 75 mg/5 mL. How many mL should the nurse administer per dose?
A) 2.5 mL
B) 3.6 mL
C) 4.2 mL
D) 5.0 mL
E) 6.4 mL
CorreCt Answer: B
Rationale: Total daily dose = 20 mg/kg × 8 kg = 160 mg/day. Per dose = 160 ÷ 3 = 53.33 mg.
Volume = (53.33 × 5) ÷ 75 = 266.65 ÷ 75 = 3.56 → 3.6 mL. Option A results from using 2 doses.
Option C results from using 4 doses. Option D results from using 75 mg dose. Option E is
incorrect.
