A nurse is preparing to administer amikacin 5 mg/kg via intermittent IV bolus to a client who weighs 219 lb. Available is amikacin 10 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 ["50"]

Step 1 is to convert the client’s weight from pounds to kilograms, since the dosage is prescribed in mg/kg. Given that 1 kg = 2.2 lb, we calculate:

219 lb ÷ 2.2 = 99.5 kg

Rounding to the nearest whole number, the client’s weight is 100 kg.

Step 2 is to determine the total dosage of amikacin required. The prescribed dosage is 5 mg/kg, so we calculate:

5 mg/kg × 100 kg = 500 mg

Step 3 is to determine the volume to administer. The available concentration of amikacin is 10 mg/mL, so we divide:

500 mg ÷ 10 mg/mL = 50 mL

Thus, the correct amount to administer is 50 mL.

Correct Answer is ["5"]

Explanation

Step 1 is to determine the amount of medication needed. This is done by dividing the desired dose by the available dose. So, we have 200 mg ÷ 40 mg/mL = 5 mL.

So, the correct answer is 5 mL.

Correct Answer is ["2"]

Explanation

Step 1 is to determine the amount of medication in 1 mL after reconstitution. This is calculated by dividing the total available medication (1000 mg) by the total volume after reconstitution (3.4 mL):

1000 mg ÷ 3.4 mL = 294.12 mg/mL

Step 2 is to determine how many mL are needed to obtain 500 mg. This is done by dividing the required dose (500 mg) by the concentration (294.12 mg/mL):

500 mg ÷ 294.12 mg/mL = 1.7 mL

Rounding to the nearest whole number, the correct amount to administer is 2 mL.
