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"]
To calculate the dosage of ketorolac, use the formula: D (desired dose) / H (have dose) = V (volume to be administered)
Plug in the values from the question: 30 mg / 15 mg/mL = 2 mL
Round the answer to the nearest whole number: 2 mL
The nurse should administer 2 mL of ketorolac injection to the client

Correct Answer is ["1.2"]
Explanation
Convert the client's weight from pounds to kilograms: 165 lb / 2.2 = 75 kg
Calculate the daily dose of phenobarbital in mg: 2 mg/kg/day x 75 kg = 150 mg/day
Divide the daily dose by 2 to get the per dose amount: 150 mg/day / 2 = 75 mg/dose
Use the formula D/H x V to find the volume to administer per dose: 75 mg/dose / 65 mg/mL x 1 mL = 1.15 mL/dose
Round the answer to the nearest tenth: 1.2 mL/dose
Correct Answer is ["0.75"]
Explanation
Convert mcg to mg by dividing by 1000
- 750 mcg / 1000 = 0.75 mg
Round the answer to the nearest hundredth
The nurse should administer 0.75 mg of digoxin IV bolus
