A client is prescribed 25 mg/kg of a medication. The weight of the client is 42 kg.
How many milligrams (mg) of medication should be administered to achieve the total prescribed dose?

A.

1250 mg

B.

1150 mg

C.

950 mg

D.

1050 mg

Answer and Explanation

The Correct Answer is B

The nurse should administer 1050 mg of medication to achieve the total prescribed dose.
 
This answer is correct because it is based on a simple multiplication calculation. The nurse can multiply the prescribed dose per kilogram by the weight of the client in kilograms to get the total dose in milligrams, as follows:

25 mg/kg x 42 kg = 1050 mg

Therefore, the nurse should administer 1050 mg of medication to the client.

Correct Answer is A

Explanation

To set the IV pump correctly, you need to calculate the following:

  • The patient's weight in kilograms
  • The dose of Zofran in milligrams
  • The infusion rate in milliliters per hour

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

176 lb / 2.2 = 80 kg

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

80 kg x 0.15 mg/kg = 12 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 mixed in 50 mL of normal saline and the infusion time is 15 minutes, plug in these values into the formula:

Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 200 mL/h

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.
