Correct Answer is D

Explanation

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.

A. 25 mL/hr B. 50 mL/hr C. 100 mL/hr D. 10 mL/hr

Correct Answer is C

Explanation

To find the milliliters per hour, you need to calculate the following:

- The patient's weight in kilograms
- The dose of Principen in milligrams
- The infusion rate in milliliters per hour using the formula: Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h

First, convert the patient's weight from pounds to kilograms by dividing by 2.2:

22 lb / 2.2 = 10 kg

Next, multiply the patient's weight by the dose of Principen per kilogram to get the total dose in milligrams:

10 kg x 25 mg/kg = 250 mg

Then, use the formula for infusion rate to find how many milliliters per hour the IV pump should deliver:

Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h

Since the medication is prepared in 50 mL of solution and the infusion time is 30 minutes, plug in these values into the formula:

Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 30 min x 60 min/h

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 100 mL/h

Therefore, the nurse should administer **100 mL/h** to infuse Principen 250 mg over 30 minutes.
