Correct Answer is ["25"]
Explanation
To answer this question, you need to use the formula:
gtt/min = (Volume x Drop factor) / Time
Plug in the given values:
gtt/min = (100 mL x 15 gtt/mL) / 60 min
Simplify and solve:
gtt/min = 1500 gtt / 60 min gtt/min = 25 gtt/min
Therefore, the nurse should set the manual IV infusion to deliver 25 gtt/min.
