A nurse is caring for client who is postoperative following an appendectomy and is prescribed D, lactated Ringer's at 150 mL/hr by continuous IV iinfusion for 12 hr. The drop factor of the manual IV tubing is 20 gtt/mL. The nurse should set the manual 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 ["50"]
Calculate the infusion rate in mL/min.
The infusion rate is 150 mL/hr.
To convert this to mL/min, we divide by 60: 150 mL/hr ÷ 60 min/hr = 2.5 mL/min.
Apply the drop factor to find the drip rate in gtt/min.
Drop factor of the tubing is 20 gtt/mL.
Drip rate = Infusion rate (mL/min) x Drop factor (gtt/mL) = 2.5 mL/min x 20 gtt/mL = 50 gtt/min

Correct Answer is ["7.5"]
Explanation
Determine the desired dose.
The nurse needs to administer 75 mg of diphenhydramine.
Calculate the available dose per 2.5 mL.
The available diphenhydramine is 25 mg/2.5 mL.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/2.5 mL) = 75 mg / (25 mg/2.5 mL) = 75 mg x (2.5 mL/25 mg) = 7.5 mL
Correct Answer is ["200"]
Explanation
Determine the total volume to be infused.
The nurse is preparing to administer 100 mL of ceftriaxone sodium in dextrose 5% in water.
Calculate the infusion rate in mL/hr.
The infusion time is 30 minutes, which is equivalent to 30/60 = 0.5 hours.
Infusion rate = Total volume / Infusion time = 100 mL / 0.5 hr = 200 mL/hr
