A nurse is caring for a school-age child who weighs 35
kg. What is the child’s daily maintenance fluid
requirement?
A. 1,200 mL/day
B. 1,500 mL/day
C. 1,800 mL/day
D. 2,400 mL/day
Correct Answer: C
Rationale: Maintenance fluid requirements in pediatrics
follow the 100/50/20 rule. For the first 10 kg, the child
needs 100 mL/kg (1,000 mL). For the next 10 kg, 50
mL/kg (500 mL). For the remaining 15 kg, 20 mL/kg (300
mL). Total equals 1,800 mL/day. This calculation
prevents dehydration and supports metabolic needs in
children whose renal concentrating ability is not fully
mature.
,A nurse is caring for a preschool-age child who weighs
18 kg. What is the daily maintenance fluid
requirement?
A. 1,200 mL/day
B. 1,400 mL/day
C. 1,600 mL/day
D. 1,800 mL/day
Correct Answer: B
Rationale: Using the 100/50/20 rule: 10 kg × 100 = 1,000
mL, plus 8 kg × 50 = 400 mL. Total is 1,400 mL/day.
This method ensures accurate hydration planning and
prevents fluid overload or deficit in pediatric patients.
A nurse is caring for a toddler who weighs 13.5 kg.
What is the daily maintenance fluid requirement?
A. 1,200 mL/day
B. 1,175 mL/day
C. 1,300 mL/day
D. 1,400 mL/day
Correct Answer: B
Rationale: First 10 kg = 1,000 mL; remaining 3.5 kg × 50
mL = 175 mL. Total = 1,175 mL/day. Accurate fluid
calculation is essential in toddlers due to higher metabolic
rates and increased insensible losses.
,A nurse is preparing to administer clindamycin 10
mg/kg to a toddler weighing 30 lb. Available is 75 mg/5
mL. How many mL per dose?
A. 2 mL
B. 3 mL
C. 4 mL
D. 5 mL
Correct Answer: B
Rationale: Convert 30 lb to kg (30 ÷ 2.2 = 13.6 kg). Dose
= 136 mg. Concentration = 15 mg/mL. 136 ÷ 15 ≈ 9
mL/day divided doses; per dose calculation leads to
approximately 3 mL. Accurate weight conversion
prevents medication toxicity.
A nurse is caring for an infant weighing 6 kg. What is
the daily maintenance fluid requirement?
A. 500 mL/day
B. 600 mL/day
C. 700 mL/day
D. 800 mL/day
Correct Answer: B
Rationale: Infants use 100 mL/kg/day. 6 × 100 = 600
mL/day. Infants require higher fluids due to immature
kidneys and high metabolic demand.
, A nurse is preparing furosemide 2 mg/kg for a 12 lb
infant. Available: 10 mg/mL. How many mL per dose?
A. 0.5 mL
B. 0.8 mL
C. 1.1 mL
D. 1.5 mL
Correct Answer: C
Rationale: Convert 12 lb to kg = 5.5 kg. Dose = 11 mg.
11 mg ÷ 10 mg/mL = 1.1 mL. Accurate conversion
ensures safe diuretic administration and prevents
electrolyte imbalance.
A nurse is preparing D5W 20 mL/kg for a 57 kg
adolescent over 4 hours. What is the infusion rate?
A. 250 mL/hr
B. 285 mL/hr
C. 300 mL/hr
D. 320 mL/hr
Correct Answer: B
Rationale: 57 × 20 = 1,140 mL total. 1,140 ÷ 4 = 285
mL/hr. Correct IV rate prevents fluid overload or
dehydration.
