CPEN Medication Administration 3

Question 1

A 10 kg toddler requires dopamine at 10 mcg/kg/min. Using a standard concentration of 400 mcg/mL, what is the infusion rate in mL/hr?

Accepted Answer

15 mL/hr

Answer

Rate (mL/hr) = (10 mcg/kg/min × 10 kg × 60 min) ÷ 400 mcg/mL = 6000 ÷ 400 = 15 mL/hr.

Question 2

Which medication should be available at the bedside whenever IV fentanyl is administered to a pediatric patient?

Accepted Answer

Naloxone (Narcan)

Answer

Naloxone reverses opioid-induced respiratory depression and must be immediately available when opioids are administered.

A 2-year-old is ordered acetaminophen 15 mg/kg PO. The liquid is available as 160 mg/5 mL. The child weighs 12 kg. How many mL should be given?

Accepted Answer

5.6 mL

Answer

Dose = 15 × 12 = 180 mg; volume = (180 ÷ 160) × 5 = 5.625 ≈ 5.6 mL.

Question 4

An infant is receiving a continuous IV infusion and the pump alarms for occlusion. What is the first nursing action?
