The healthcare provider prescribes furosemide 120 mg intravenously (IV) for a client with fluid overload. Furosemide is available in a vial labeled 10 mg/mL, and the recommended rate for IV administration is 40 mg/minute. The nurse should administer the medication over what length of time in minutes? (Enter numeric value only.)
The Correct Answer is ["3"]
Here's how to calculate the duration (minutes) for the nurse to administer furosemide:
Prescribed dose: 120 mg furosemide (given)
Recommended rate: 40 mg/minute (given)
We need to find the total time (minutes) required to administer the prescribed dose (120 mg) at the recommended rate (40 mg/minute).
Time (minutes) = Dose (mg) / Rate (mg/minute)
Time (minutes) = 120 mg / 40 mg/minute
Time (minutes) = 3 minutes
Therefore, the nurse should administer the medication over 3 minutes.

Correct Answer is ["0.7"]
Explanation
The nurse should administer 0.7 mL of diphenhydramine.
Here's the calculation:
Medication dosage: 35 mg (diphenhydramine)
Medication concentration: 50 mg/mL (given on the syringe label)
We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine.
Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 35 mg / 50 mg/mL
Volume to administer (mL) = 0.7 mL (round to nearest tenth)
Therefore, the nurse should administer 0.7 mL of diphenhydramine
Correct Answer is ["440"]
Explanation
The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes.
First, let’s find out how many mL should be delivered per minute.
We divide the total volume by the total time in minutes:
RateinmL/min = 110mL /15min ≈ 7.33mL/min
We need to convert this to mL/hr since we want the rate in mL/hr.
There are 60 minutes in an hour, so:
RateinmL/hr = 7.33mL/min×60 = 440mL/hr
So, the nurse should program the secondary infusion to deliver 440 mL/hr.
