Correct Answer is ["0.71"]

Explanation

To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.

The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.

The desired dose is 250 mg.

So, you can use the following formula:

Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)

Volume to administer (mL) = 250 mg / 350 mg/mL

Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)

Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.

Correct Answer is ["2.3"]

Explanation

To calculate the amount of morphine (in mL) the nurse should administer, follow these steps:

Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg

Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL

Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.
