A client is receiving a secondary intravenous (IV) infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["83"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtt/min) = 500 mL x 20 gtt/mL / 120 min
Simplifying, we get:
Infusion rate (gtt/min) = 10000 gtt / 120 min
Dividing both sides by 120, we get:
Infusion rate (gtt/min) = 83.33 gtt/min
Rounding to the nearest whole number, we get:
Infusion rate (gtt/min) = 83 gtt/min

Correct Answer is ["3.5"]
Explanation
To calculate the total volume of diluted medication, we need to use the formula:
Total volume (mL) = Drug volume (mL) + Diluent volume (mL)
First, we need to calculate the drug volume by dividing the dose by the concentration. In this case, 1 mg of hydromorphone is equivalent to 0.5 mL of hydromorphone injection.
Plugging in the given values, we get:
Total volume (mL) = 0.5 mL + 3 mL
Simplifying, we get:
Total volume (mL) = 3.5 mL
Correct Answer is ["133"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 132 pounds is equivalent to 59.928 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 59.928 kg x 500 mL / 45000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 132.84 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 133 mL/h
