A nurse is preparing to administer nitroprusside 2 mcg/kg/min via continuous IV infusion to a client who weighs 75 kg. Available is nitroprusside 50 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 whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["45"]
Infusion rate in mL/h = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL) In this case, the dose is 2 mcg/kg/min and the concentration is 50 mg/250 mL or 200 mcg/mL. Therefore, the infusion rate is:
Infusion rate (mL/h) = 2 x 75 x 60 / 200 Infusion rate (mL/h) = 45
The nurse should set the IV pump to deliver 45 mL/h.

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.
Correct Answer is ["400"]
Explanation
Infusion rate (mL/hr) = 200 mL / 0.5 hr Infusion rate (mL/hr) = (200 mL/hr) *2
= 400mls/hr
