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 ["1.8"]
Explanation
Dose = Desired dose / Available dose x Volume Therefore;
Dose = (56 mg / 160 mg) x 5 mL Therefore;
Dose = 0.35 x 5 mL Dose = 1.75 mL
Round to the nearest tenth: Dose = 1.8 mL
The nurse should administer 1.8 mL
Correct Answer is C
Explanation
A. Offering the medication now to prevent saturation of the perineal pad is incorrect because the prescription specifies administering the medication only if the pad is saturated within 15 minutes. Preventative administration is not indicated.
B. Giving the medication each time the client saturates the perineal pad within 15 minutes is incorrect because the prescription states "one time only." Repeated administration is not in line with the prescription.
C. Administering the medication once if the client saturates the perineal pad within 15 minutes is correct. This interpretation aligns with the prescription's directive to give the medication one time only under the specified condition.
D. Waiting to administer the medication after the client saturates a perineal pad is incorrect because the prescription does not specify a waiting period after saturation. The medication should be given immediately if the saturation occurs within the 15-minute timeframe.
