A nurse is preparing to administer fentanyl 0.5 mcg/kg via IV bolus to a client who weighs 187 lb. Available is fentanyl 50 mcg/ml. How many mi should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.9"]

Convert the client’s weight from pounds to kilograms:
- 1 kilogram (kg) = 2.2 pounds (lb)
- Weight in kg = 187 lb / 2.2 = 85 kg
Calculate the dose of fentanyl in micrograms (mcg):
- Dose = 0.5 mcg/kg × 85 kg = 42.5 mcg
Determine the volume of fentanyl to administer:
- Available concentration is 50 mcg/ml
- Volume (ml) = Dose (mcg) / Concentration (mcg/ml)
- Volume (ml) = 42.5 mcg / 50 mcg/ml = 0.85 ml
Round the answer to the nearest tenth:
- Rounded volume = 0.9 ml

Correct Answer is ["1.5"]

Explanation

First, we need to calculate the amount of cefazolin 500 mg in milligrams per milliliter (mg/mL) using the information provided:

Cefazolin concentration after reconstitution = 330 mg/mL Amount of cefazolin needed per dose = 500 mg

Now we can calculate the volume (mL) required for the dose:

Volume (mL) = Amount of cefazolin needed per dose / Cefazolin concentration after reconstitution

Volume (mL) = 500 mg / 330 mg/mL ≈ 1.52 mL

Rounded to the nearest tenth, the nurse should administer approximately 1.5 mL of cefazolin per dose.

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.
