Answer and Explanation

The Correct Answer is ["8"]

The healthcare provider prescribes regular insulin 8 units/hour intravenously (IV).

The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline, so the concentration of insulin in the IV solution is 1 unit/mL (100 units / 100 mL).

Since the healthcare provider prescribes 8 units/hour of insulin, the nurse should program the infusion pump to deliver 8 mL/hour of the IV solution (8 units/hour / 1 unit/

Correct Answer is ["120"]

Explanation

The healthcare provider prescribes a continuous infusion of labetalol at 2 mg/minute.

Labetalol HCI Injection USP 200 mg in 200 mL of 5% Dextrose Injection, USP, is delivered to the unit. This means that for every mL of the solution, there is 1 mg of labetalol (200 mg / 200 mL = 1 mg/mL).

To administer a dose of 2 mg/minute, the nurse should program the infusion pump to deliver 120 mL/hour (2 mg/minute × 60 minutes/hour = 120 mg/hour; 120 mg/hour ÷ 1 mg/mL = 120 mL/hour).

Correct Answer is ["375"]

Explanation

To calculate the number of milliliters that remain to be infused, we can use the following formula: Volume remaining = Total volume - Volume infused

In this case, the total volume is 1000 mL and the volume infused is:

125 mL/hour x 5 hours = 625 mL So the volume remaining is:

1000 mL - 625 mL = 375 mL.
