A client receives a prescription for a single dose of midazolam 2 mg IV to be administer before a scheduled procedure. The vial is label, *4 mg/2 mL." How many mL should the nurse administer? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["1"]

Here's the breakdown:

Prescribed dose: 2 mg midazolam (given)

Vial concentration: 4 mg/2 mL (label)

We need to find the volume containing the 2 mg dose considering the concentration.

Calculation:

Volume (mL) = Dose (mg) / (Concentration (mg/mL) / 2)

We divide the concentration by 2 because we need the volume that delivers 2 mg (half the concentration).

Volume (mL) = 2 mg / (4 mg/mL / 2)

Volume (mL) = 2 mg / 2 mg/mL

Volume (mL) = 1 mL

Therefore, the nurse should administer 1 mL of midazolam to deliver the prescribed dose of 2 mg.

Correct Answer is ["200"]

Explanation

Here's why:

The entire dose (400 mg) is contained within the 200 mL bag.

The information doesn't suggest the bag needs to be emptied completely during the infusion.

Our goal is to deliver the 400 mg dose over the 1-hour infusion period.

Therefore, the nurse should program the infusion pump to deliver the entire volume of the bag (200 mL) containing the medication over the 1-hour timeframe.

Calculation:

Volume to deliver (mL/hr) = Total volume of bag (mL) / Infusion time (hours)

Volume to deliver (mL/hr) = 200 mL / 1 hour

Volume to deliver (mL/hr) = 200 mL/hr

Therefore, the nurse should program the infusion pump to deliver 200 mL/hr.

Correct Answer is ["18"]

Explanation

Here's how to calculate the rate (mL/hour) for the infusion pump:

Heparin concentration:

The medication is available in a 250 mL bag containing 20,000 units of heparin.

Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)

Heparin concentration (units/mL) = 20,000 units / 250 mL

Heparin concentration (units/mL) = 80 units/mL (round to nearest whole number)

Prescribed heparin dose: 1,400 units/hour (given)

We need to find the volume delivered per hour (mL/hour) to achieve the prescribed heparin dose (1400 units/hour) considering the concentration (80 units/mL).

Infusion rate (mL/hour) = Dose (units/hour) / Concentration (units/mL)

Infusion rate (mL/hour) = 1400 units/hour / 80 units/mL

Infusion rate (mL/hour) = 17.5 mL/hour (round to nearest whole number)

Therefore, the nurse should program the infusion pump to deliver approximately 18 mL/hour.
