A nurse is preparing to administer oxymorphone 1.5 mg IM to a client.
Available is oxymorphone 1 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
Step 1 is to calculate the volume to administer using the formula:
Dose (mg) ÷ Concentration (mg/mL)
Given that the prescribed dose is 1.5 mg and the available concentration is 1 mg/mL, we calculate:
1.5 mg ÷ 1 mg/mL = 1.5 mL
Since the result is already rounded to the nearest tenth, the nurse should administer 1.5 mL of oxymorphone.

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.
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.
