A nurse is preparing to administer cefazolin IVPB over 20 min. Available is cefazolin 1 g in 100 mL of dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 15gtt/mL. The nurse should set the IV infusion 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 ["75"]
Step-by-Step Calculation
Understanding the Problem
We need to administer 100 mL of cefazolin over 20 minutes.
The drop factor of the tubing is 15 gtt/mL.
We need to calculate the drip rate in gtt/min.
Calculations
Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Total volume (mL) / Infusion time (min)
Infusion rate = 100 mL / 20 min = 5 mL/min
Calculate the drip rate:
Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)
Drip rate = 5 mL/min X 15 gtt/mL = 75 gtt/min
The nurse should set the IV infusion to deliver 75 gtt/min.

Correct Answer is ["0.6"]
Explanation
The nurse is administering diphenhydramine at a dose of 30 mg. The available concentration is 50 mg/mL.
We can set up a proportion to find out how many mL contain 30 mg:
50mg/1mL = 30mg/ xmL
Solving for x gives us:
X = 30mg×1mL / 50mg = 0.6mL
So, the nurse should administer 0.6 mL of diphenhydramine.
Correct Answer is ["35"]
Explanation
Step-by-Step Calculation
Understanding the Problem
We need to administer 840 mL of enteral nutrition over 24 hours.
We need to calculate the infusion rate in mL/hr.
Calculations
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 840 mL / 24 hr = 35 mL/hr
The nurse should set the infusion pump to deliver 35 mL/hr.
