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 ["0.6"]
Explanation
Step 1: Determine the amount of enoxaparin in mg per mL. 60 mg ÷ 0.6 mL = 100 mg/mL
Result: 100 mg/mL
Step 2: Calculate the volume in mL needed to administer 55 mg. 55 mg ÷ 100 mg/mL = 0.55 mL
Result: 0.55 mL
Step 3: Round the result to the nearest tenth. 0.55 mL rounded to the nearest tenth = 0.6 mL
Result: 0.6 mL
The nurse should administer 0.6 mL of enoxaparin.
Correct Answer is ["8"]
Explanation
Number of tablets = (Dose per administration x Number of administrations per day) / Tablet strength
Number of tablets = (500 mg x 4) / 250 mg
Number of tablets = 2000 mg / 250 mg Number of tablets = 8
Therefore, the nursing staff should administer 8 tablets in a 24hrs.
