A nurse is preparing to administer amiodarone 300 mg IV bolus over 10 min to a client. Available is amiodarone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["6"]

To calculate the volume (mL) needed to administer 300 mg of amiodarone using a concentration of 50 mg/mL, you can use the following formula:

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

In this case, the dose is 300 mg, and the concentration is 50 mg/mL:

Volume (mL) = 300 mg / 50 mg/mL = 6 mL

So, the nurse should administer 6 mL of amiodarone.

Correct Answer is ["0.9"]

Explanation

  • 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 ["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.
