A client is to receive a continuous infusion of insulin for diabetic ketoacidosis. at 5 units per hour. The medication is mixed: 100 units of Insulin in 100 mL of IV fluid. At what rate should the nurse set the IV pump? (Use a preceding, zero if it applies. Do not use trailing zeros. Round to the nearest tenth)
The Correct Answer is ["5"]
Determine the concentration of the insulin solution:
There are 100 units of insulin in 100 mL of IV fluid.
Concentration = 100 units / 100 mL = 1 unit/mL
Calculate the volume (in mL) needed per hour:
The client needs 5 units per hour.
Since the concentration is 1 unit/mL, this means the client needs 5 mL per hour.
Set the IV pump:
The IV pump should be set to infuse at 5 mL/hr.

Correct Answer is ["30"]
Explanation
Convert the total volume to milliliters (mL):
The volume is already given in mL: 150 mL
Convert the time to minutes:
1 hour = 60 minutes
Use the drop factor to find the drops per mL:
The drop factor is given as 12 gtt/mL.
Calculate the total drops:
Total drops = Volume (mL) x Drop factor (gtt/mL)
Total drops = 150 mL x 12 gtt/mL = 1800 gtt
Calculate the flow rate in drops per minute (gtt/min):
Flow rate (gtt/min) = Total drops / Time (minutes)
Flow rate (gtt/min) = 1800 gtt / 60 minutes = 30 gtt/min
Correct Answer is ["3"]
Explanation
Determine the Desired Dose:
The client needs 1.5 mg of alprazolam.
Determine the Available Dose:
Each tablet contains 0.5 mg of alprazolam.
Calculate the Number of Tablets:
Number of Tablets = Desired Dose / Available Dose
Number of Tablets = 1.5 mg / 0.5 mg
Number of Tablets = 3
