Answer and Explanation

The Correct Answer is ["9.4"]

Step 1 is to calculate the dose to be administered which is 300 mg. Step 2 is to calculate the concentration of the available medication which is 160 mg/5 mL. Step 3 is to calculate the volume to be administered as (300 mg ÷ (160 mg/5mL)) = 9.375 mL.

So, the correct answer is, after analyzing all steps, the nurse should administer 9.4 mL per dose (rounded to the nearest tenth).

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.

Correct Answer is ["68"]

Explanation

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

99 lb ÷ 2.2 = 45 kg

Rounding to the nearest whole number, the client’s weight is 45 kg.

Step 2 is to determine the total dosage of acetaminophen required. The prescribed dosage is 15 mg/kg, so we calculate:

15 mg/kg × 45 kg = 675 mg

Step 3 is to determine the volume to administer. The available concentration of acetaminophen is 1,000 mg/100 mL, which simplifies to 10 mg/mL. So, we divide:

675 mg ÷ 10 mg/mL = 67.5 mL

Rounding to the nearest whole number, the correct amount to administer is 68 mL.
