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 ["100"]

Explanation

The nurse should set the infusion pump to deliver the entire 150 mL over the course of 90 minutes.

First, convert the time from minutes to hours because the rate is required in mL/hr.

90 minutes is 1.5 hours (since 1 hour = 60 minutes).

Therefore, the IV pump should be set to deliver:

Rate(mL/hr)=Time(hr)Totalvolume(mL)=1.5hr150mL

After performing the calculation, we find that the rate equals 100 mL/hr.

So, the nurse should set the infusion pump to deliver 100 mL/hr. This is rounded to the nearest whole number as per the instructions.

Correct Answer is ["3"]

Explanation

Concentration of penicillin G benzathine: 1,200,000 units/2 mL (given on the syringe label)

Prescribed dose: 1,800,000 units

We need to find the volume (in mL) that delivers the prescribed dose (1,800,000 units) considering the available concentration.

Dosage calculation:

To administer the prescribed dose, we need to find the volume that contains at least 1,800,000 units.

Since the available concentration is 1,200,000 units/2 mL, one prefilled syringe provides 1,200,000 units.

We can calculate the number of syringes needed to deliver the prescribed dose:

Number of syringes = Prescribed dose (units) / Concentration per syringe (units)

Number of syringes = 1,800,000 units / 1,200,000 units/syringe

Number of syringes = 1.5 (round up to 2 since a partial dose wouldn't be sufficient)

2 mL per syringe x 2 syringes = 4 mL

However, the prefilled syringes likely come in whole-number doses. Checking the available options:

A single prefilled syringe provides 1,200,000 units (which is not enough).

Two prefilled syringes would provide a total of 2,400,000 units (more than enough).

Therefore, to ensure at least the prescribed dose is administered, the nurse should administer 3 mL.

This is achieved by using one and a half (rounded up to two) prefilled syringes.
