A nurse is preparing to administer heparin 17,500 units subcutaneous every 12 hr. Available is heparin injection 20,000 units/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.88"]
Step 1 is to calculate the volume of heparin to be administered. The calculation is as follows: 17,500 units ÷ (20,000 units/mL) = 0.875 mL.
So, the correct answer is 0.88 mL (rounded to the nearest hundredth).

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 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.
