A nurse is preparing to administer lorazepam 0.05 mg/kg via IV bolus to a client who weighs 175 lb. Available is lorazepam 2 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 ["2"]

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 ["2"]

Explanation

Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 15 mg/mL.

So, we calculate 30 mg ÷ 15 mg/mL = 2 mL.

So the correct answer is 2 mL.

Correct Answer is ["1.5"]

Explanation

Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 20 mg/mL.

So, we calculate 30 mg ÷ 20 mg/mL = 1.5 mL. Rounded to the nearest tenth, this is 1.5 mL.

So the correct answer is 1.5 mL.
