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.

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 ["0.75"]
Explanation
Step 1 is to convert mcg to mg. This is done by dividing the total amount of medication (750 mcg) by 1000 (since 1 mg = 1000 mcg). So, 750 mcg ÷ 1000 = 0.75 mg.
