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 ["57"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. We know that 1 kg is approximately 2.2 lb. So, the client’s weight in kg is 178 lb ÷ 2.2 lb/kg = 80.91 kg. Step 2 is to calculate the total dose of acetylcysteine. The total dose is 140 mg/kg × 80.91 kg = 11327.4 mg. Step 3 is to calculate the volume to administer. The volume is 11327.4 mg ÷ 200 mg/mL = 56.637 mL.
So, the correct answer is 57 mL after rounding to the nearest whole number.
Correct Answer is ["8"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in units/kg. There are approximately 2.2 lb/kg, so 130 lb ÷ 2.2 lb/kg = 59.1 kg. The doctor ordered calcitonin at a dosage of & units/kg, so we multiply the client’s weight in kg by the dosage: 59.1 kg × & units/kg = & units. The medication is available at a concentration of 200 units/mL, so we divide the total units needed by the units per mL: & units ÷ 200 units/mL = & mL.
So, the correct answer is 8mL.
