A client with angina pectoris is receiving intravenous (IV) nitroglycerin 50 mg/250 mL of D5W to be infused over 24 hours via pump. How many mL/hour should the nurse program the infusion pump?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["10"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Volume (mL) / Time (h)
Plugging in the given values, we get:
Infusion rate (mL/h) = 250 mL / 24 h
Simplifying, we get:
Infusion rate (mL/h) = 10.42 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 10 mL/h

Explanation
To calculate the number of tablets, we need to use the formula:
Number of tablets = Dose (mcg) / Strength (mcg/tablet)
First, we need to calculate the dose by multiplying the prescribed rate by the weight in kilograms. To convert the weight from pounds to kilograms, we multiply by 0.454. In this case, 154 pounds is equivalent to 69.916 kg.
Plugging in the given values, we get:
Number of tablets = 1.6 mcg/kg x 69.916 kg / 112 mcg
Simplifying, we get:
Number of tablets = 1
Correct Answer is ["30"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/h) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 3 mg/h x 500 mL / 50 mg
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h
