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 C
Explanation
This answer is correct because BSA is the most accurate method for calculating the child's dose from the adult dose¹². BSA takes into account the child's weight and height, and reflects the physiological function and organ growth of the child beter than weight alone¹. BSA can be calculated using a nomogram or a formula based on the child's weight and height¹. The child's dose can then be calculated by multiplying the adult dose by the ratio of the child's BSA to the average adult BSA (1.73 m2)¹. For example:
Child dose by BSA = (mg/day) = Adult Dose in mg/day x BSA in m2 / 1.73
OR
Child dose by BSA = (mg/day) = Adult Dose in mg/m2 x BSA in m2
The other options are not correct because they are not accurate methods for calculating the child's dose from the adult dose. Actual body weight and ideal body weight may not account for individual variations in pharmacokinetics, pharmacodynamics, or clinical response. Actual body height is not a reliable indicator of drug dosage, as it does not reflect the body mass or organ function of the child.
Correct Answer is C
Explanation
The nurse should administer 1 mL per dose to the patient.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
30 mg / 1 mL = 30 mg / x mL
Cross-multiplying and solving for x gives:
x = 1 mL
Therefore, the nurse should administer 1 mL of Toradol injection to deliver 30 mg of the medication to the patient.
