Correct Answer is ["1.5"]

Explanation

Step-by-Step Calculation

Understanding the Problem

Desired dose: 75 mg hydroxyzine hydrochloride

Available concentration: 50 mg/mL

We need to find the volume to administer.

Calculations

Calculate the volume to administer:

Volume (mL) = Desired dose (mg) / Concentration (mg/mL)

Volume = 75 mg / 50 mg/mL = 1.5 mL

The nurse should administer 1.5 mL of hydroxyzine hydrochloride.

Correct Answer is ["0.5"]

Explanation

The nurse should administer 0.5 mL of epinephrine.

Step-by-Step Calculation

Understanding the Problem

Desired dose: 0.5 mg epinephrine

Available concentration: 1 mg/mL epinephrine

Setting Up the Equation

We can use the following formula:

Desired dose (mg) = Concentration (mg/mL) X Volume (mL)

We need to find the volume (mL).

Calculating the Volume

0.5 mg = 1 mg/mL X Volume (mL)

To isolate Volume, we divide both sides by 1 mg/mL:

Volume (mL) = 0.5 mg / (1 mg/mL)

Volume (mL) = 0.5 mL

The nurse should administer 0.5 mL of epinephrine.
