A healthcare provider orders nitroprusside (100 mg/1 mL) 3 mcg/kg/minute for a patient weighing 154 lb. What rate (mL/hr) should the nurse program into the IV pump?
126 mL/hr
1.26 mL/hr
1260 mL/hr
12.6 mL/hr
The Correct Answer is B
First, we need to convert the patient's weight from pounds to kilograms using the conversion factor 1 kg =
2.2 lb:
154 lb / 2.2 lb/kg = 70 kg
Next, we need to calculate the dose of nitroprusside in mcg/min using the formula Dose = Weight × Dosage:
Dose = 70 kg × 3 mcg/kg/min = 210 mcg/min
Then, we need to convert the dose of nitroprusside from mcg/min to mg/hr using the conversion factor 1 mg = 1000 mcg:
210 mcg/min × 1 mg/1000 mcg × 60 min/hr = 12.6 mg/hr
Finally, we need to calculate the rate of nitroprusside in mL/hr using the formula Rate = Dose/Concentration:
Rate = 12.6 mg/hr / 100 mg/mL = 0.126 mL/hr
To round to the nearest hundredth, we get 0.13 mL/hr, which is approximately equal to 1.26 mL/hr.
Therefore, the nurse should program the IV pump to deliver nitroprusside at a rate of 1.26 mL/hr.

Correct Answer is D
Explanation
To answer this question, we need to calculate the infusion rate in mL per hour, then multiply it by the total time in hours, and finally divide it by 1000 to get the volume in litres.
The infusion rate in mL per hour is the amount of fluid that is given to a patient over a period of time. It can be calculated by dividing the total volume of fluid in mL by the total time in hours². In this case, the infusion rate is:
2.75 mL/min × 60 min/h = 165 mL/h
The total volume of fluid in mL is the infusion rate multiplied by the total time in hours. In this case, the total volume is:
165 mL/h × 7 h = 1155 mL
The volume in litres is the volume in mL divided by 1000. In this case, the volume in litres is:
1155 mL / 1000 = 1.16 L
Therefore, the correct answer is d. 1.16 L.
Correct Answer is C
Explanation
The instruction that should be given to this client for the effective management of hypertension is to take
**five tablets** of bisoprolol per day, each containing 100 mg.
This is because the new order of 500 mg of bisoprolol per day is twice as much as the current dose of 250 mg of bisoprolol per day (two and a half tablets of 100 mg each). Therefore, the client needs to double the number of tablets they take per day from two and a half to five.
