A child is prescribed 10 mg/kg of a medication, and the child weighs 15 kg. The medication is available as 50 mg/mL. How many milliliters should the nurse administer?
Correct Answer: 3 mL
Rationale: Calculation: 15 kg × 10 mg/kg = 150 mg. Volume = 150 mg ÷ 50 mg/mL = 3 mL. Since no options are provided, the calculated volume is noted for accuracy.
How should the nurse position a child who is about to undergo a lumbar puncture?
- A. Prone position
- B. Fowler's position

- A. An extra supply of sterile dressing
- B. An endotracheal tube and oxygen supply
- C. Equipment to administer pain medication

If the child weighs 30 kg, what is the hourly flow rate in milliliters? Use the standard 100 mL/kg/day for the first 10 kg of body weight, 50 mL/kg/day for the next 10 kg of body weight, and 20 mL/kg/day for each kilogram above 20 kg of body weight for daily maintenance.
Correct Answer: 70.83 mL/hour
Rationale: Calculation: First 10 kg = 100 mL/kg/day × 10 = 1000 mL/day; Next 10 kg = 50 mL/kg/day × 10 = 500 mL/day; Last 10 kg = 20 mL/kg/day × 10 = 200 mL/day. Total = 1000 + 500 + 200 = 1700 mL/day. Hourly rate = 1700 ÷ 24 = 70.83 mL/hour. Since no exact option is provided, the closest reasonable answer is assumed as correct based on standard practice.
