Question

The nurse says her fentanyl syringe (10 mcg/mL) is running at a rate of 0.45 mL/hr on a 1.5 kg baby. What dose is this in mcg/kg/hr?

a. 3 mcg/kg/hr

b.6 mcg/kg/hr

c.0.3 mcg/kg/hr

d. 10.45 mcg/kg/hr

Answer 1

the correct answer is A 3 kcg/kg/hr

Answer 2

The dose of fentanyl in mcg/kg/hr can be calculated by multiplying the concentration of fentanyl in the syringe (10 mcg/mL) by the rate at which it is being administered (0.45 mL/hr) and then dividing by the weight of the baby (1.5 kg).

This gives us a dose of (10 mcg/mL * 0.45 mL/hr) / 1.5 kg = 3 mcg/kg/hr. So the correct answer is a. 3 mcg/kg/hr.
