A nurse is preparing to administer ketorolac 30 mg IM to a client.
Available is ketorolac injection 15 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.)
The Correct Answer is ["2"]
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.

Explanation
Step 1: Calculate the volume of cefazolin needed for a 250 mg dose.
Volume of cefazolin = 250 mg ÷ 225 mg/mL = 1.11 mLStep 2: Round the answer to the nearest tenth.
1.11 mL rounded to the nearest tenth is 1.1 mL.Therefore, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride.
Correct Answer is ["5"]
Explanation
Step 1 is to calculate the total daily dose. The total daily dose is 150 mg. Step 2 is to divide the total daily dose by the number of doses. The number of doses is 3. So, the calculation is 150 mg ÷ 3 = 50 mg/dose. Step 3 is to calculate the volume to administer using the available medication concentration. The available medication concentration is 50 mg/5 mL. So, the calculation is 50 mg ÷ (50 mg/5 mL) = 5 mL.
So, the correct answer is 5 mL, after rounding to the nearest whole number.
