A nurse needs to administer an IV infusion at a rate of 125mL/hr. How many drops per minute should be delivered if the drop factor of the tubing set is 15gtt/mL?
31gtt/min
32gtt/min
33gtt/min
34gtt/min
The Correct Answer is A
To calculate drops per minute, the nurse should multiply the infusion rate in mL/hr by the drop factor in gtt/mL and divide by 60min/hr. In this case, the infusion rate is 125mL/hr and the drop factor is15gtt/mL so, the nurse should deliver(125mL/hrx15gtt/mL)/60min/hr=31gtt/min.

Correct Answer is B
Explanation
To calculate the infusion rate in mL/hr, the nurse should divide the total volume in mL by the total infusion time in hours. In this case, the total volume is 1000mL and total infusion time is hours so, the nurse should deliver 1000mL/8hr=125mL/hr.
Correct Answer is A
Explanation
To calculate the dose of a medication based on the client’s weight, the nurse should multiply the recommended dose by the client’s weight in kg. In this case, the recommended dose is 5 mg/kg and the client weighs 70 kg, so the nurse should administer 5 mg/kg x 70 kg = 350 mg of the medication.
