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 ["0.5"]
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 12.5 mg ÷ 25 mg/mL = 0.5 mL.
So, the correct answer is 0.5 mL.
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.
