A nurse is preparing to administer dopamine 5 mcg/kg/min via continuous IV infusion to a newborn who weighs 4.4 kg and has septic shock. Available in dopamine 200 mg in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.7"]
The dose of dopamine in mg/hr: 5 mcg/kg/min x 4.4 kg x 60 min/hr = 1320 mcg/hr Converted to mg: 1320 mcg/hr / 1000 mcg/mg = 1.32 mg/hr
Infusion rate in mL/hr: 1.32 mg/hr / (200 mg/250 mL) = 1.65 mL/hr Rounded off to the nearest tenth: 1.7 mL/hr

Correct Answer is ["1.7"]
Explanation
The dose of dopamine in mg/hr: 5 mcg/kg/min x 4.4 kg x 60 min/hr = 1320 mcg/hr Converted to mg: 1320 mcg/hr / 1000 mcg/mg = 1.32 mg/hr
Infusion rate in mL/hr: 1.32 mg/hr / (200 mg/250 mL) = 1.65 mL/hr Rounded off to the nearest tenth: 1.7 mL/hr
Correct Answer is ["2"]
Explanation
To calculate the number of tablets to administer, you need to divide the prescribed dose by the available dose. In this case, the prescribed dose is 0.25 mg and the available dose is 0.125 mg. Therefore, the number of tablets is:
0.25 mg / 0.125 mg = 2 tablets
The nurse should administer 2 tablets of digoxin 0.125 mg to the client.
