A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The IV administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)

The Correct Answer is ["21"]
To calculate the gtt/min, use the formula: gtt/min = (volume in mL x drop factor in gtt/mL) / time in min
Plug in the given values: gtt/min = (250 mL x 10 gtt/mL) / 120 min Simplify and solve: gtt/min = 2500 gtt / 120 min = 20.83 gtt/min
Round to the nearest whole number: gtt/min = 21
The nurse should regulate the infusion at 21 gtt/min

Correct Answer is ["60"]
Explanation
- Calculate the dose of lamivudine in mg: 150 mg x 2 = 300 mg
- Divide the dose by the concentration to get the volume in mL: 300 mg / 10 mg/mL = 30 mL
- Multiply the volume by the number of doses per day to get the total volume in a 24-hour period: 30 mL x 2 = 60 mL
- The nurse should administer 60 mL of lamivudine oral solution in a 24-hour period.
Correct Answer is ["0.64"]
Explanation
- Calculate the dose of methylprednisolone in mL using the formula: Dose (mL) = Ordered Dose (mg) / Available Dose (mg) x Available Volume (mL)
- Substitute the values from the question: Dose (mL) = 40 mg / 125 mg x 2 mL
- Simplify the expression: Dose (mL) = 0.64 mL
- Round to the nearest hundredth if needed: Dose (mL) = 0.64 mL
- The nurse should administer 0.64 mL of medication.
