Oxycodone hydrochloride 30 mg is ordered for a patient with pain after surgery. The patient rates the pain at a level of 8/10. Liquid oxycodone hydrochloride 20 mg/mL is available.
How many mL should be administered by the nurse?
0.5 mL
1 mL
2 mL
1.5 mL
The Correct Answer is D
This is a dosage calculation problem. To solve it, we need to use the formula:A
Desired dose ÷ Available dose × Available quantity = Quantity to give
In this case, the desired dose is 30 mg, the available dose is 20 mg/mL, and the available quantity is 1 mL. Plugging these values into the formula, we get:
30 ÷ 20 × 1 = 1.5
Therefore, the nurse should administer **1.5 mL** of liquid oxycodone hydrochloride to the patient.

Correct Answer is A
Explanation
To find the rate in mL/hr, you need to calculate the following:
- The concentration of nitroglycerin in the IV solution in mcg/mL
- The infusion rate in mL/hr using the formula: Infusion rate (mL/h) = (Dose (mcg/min) x 60 min/h) / Concentration (mcg/mL)
First, convert the concentration of nitroglycerin from mg to mcg by multiplying by 1000:
125 mg x 1000 = 125,000 mcg
Then, divide the amount of nitroglycerin by the volume of the IV solution to get the concentration in mcg/mL:
125,000 mcg / 500 mL = 250 mcg/mL
Next, plug in the values into the formula for infusion rate:
Infusion rate (mL/h) = (42 mcg/min x 60 min/h) / 250 mcg/mL
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 10.08 mL/h
Therefore, the nurse should program the IV pump to deliver **10.1 mL/h** to infuse nitroglycerin at 42 mcg/minute.
Correct Answer is D
Explanation
To find the milliliters to administer, you need to use the formula for dosage calculation:
Volume (mL) = Dose ordered (mg) / Dose available (mg) x Volume available (mL)
Since the dose ordered is 275 mg, the dose available is 500 mg, and the volume available is 2 mL, plug in these values into the formula:
Volume (mL) = 275 mg / 500 mg x 2 mL
Simplify and solve for the volume:
Volume (mL) = 1.1 mL
Therefore, the nurse should administer **1.1 mL** of Primaxin to the patient.
