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 D
Explanation
This answer is correct because it is based on a series of unit conversions and calculations. The nurse should follow these steps to provide safe medication to the child:
1) Convert the child's weight from pounds to kilograms by dividing by 2.2, since there are 2.2 lbs in 1 kg. The child weighs 20 kg.
2) Multiply the prescribed dose per kilogram by the child's weight in kilograms to get the total dose in milligrams. The child needs 40 mg of pyrimethamine.
3) Use the ratio given on the drug label to convert the total dose in milligrams to the volume in milliliters. The nurse can set up a proportion as follows:
1 mg / 5 mL = 40 mg / x mL
Cross-multiplying and solving for x gives:
x = 200 mL
Therefore, the nurse should administer 200 mL of medication to deliver 40 mg of pyrimethamine to the child.
4) Convert the volume in milliliters to the volume in teaspoons by dividing by 5, since there are 5 mL in 1 tsp. The nurse should administer 40 tsp of medication to the child.
5) Convert the volume in teaspoons to the volume in cups by dividing by 48, since there are 48 tsp in 1 cup. The nurse should administer 0.83 cups of medication to 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.
