Correct Answer is ["2"]

Explanation

Step 1 is to convert the client’s weight from pounds to kilograms. So, the client’s weight in kg is 175 lb ÷ 2.2 lb/kg = 79.55 kg. Step 2 is to calculate the total dose of lorazepam. The total dose is 0.05 mg/kg × 79.55 kg = 3.9775 mg. Step 3 is to calculate the volume to administer. The volume is 3.9775 mg ÷ 2 mg/mL = 1.98875 mL.

So, the correct answer is 2 mL after rounding to the nearest whole number.

Correct Answer is ["50"]

Explanation

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.
