A nurse is preparing to administer 0.9% sodium chloride 1,000 mL IV to infuse over 4 hr. The drop factor on the manual tubing is 12 gtt/mL. The nurse should regulate the flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["50"]
To calculate the flow rate in drops per minute (gtt/min), you can use the formula:
Flow rate (gtt/min) = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)
Given:
Volume = 1000 mL
Drop factor = 12 gtt/mL
Time = 4 hours
Convert 4 hours to minutes:
4 hours × 60 minutes/hour = 240 minutes
Then
Flow rate (gtt/min) = 1000 mL × 12 gtt/mL ÷ 240 min
Flow rate (gtt/min) = 12000 gtt ÷ 240 min
Flow rate (gtt/min) = 50 gtt/min
Therefore, the nurse should regulate the flow rate to deliver 50 gtt/min.

Correct Answer is ["100"]
Explanation
To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.
Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.
Correct Answer is ["0.8"]
Explanation
To calculate the dose of enoxaparin, we need to convert the client's weight from pounds to kilograms.
1 kg=2.2 Ib
? kg= 165Ib
=165/2.2
=75kg
Desired med is 1mg/kg
total dose to administer= 75mg
Available formulation is 30mg/0.3ml
total volume to administer
30mg=0.3ml
75mg= 75*0.3/30
=0.75ml
Rounded off to the nearest tenth = 0.8ml
