A primary healthcare provider has prescribed 1.8 mg/kg of brentuximab for a client who has Hodgkin lymphoma and weighs 60 kg. The nurse has on hand 50 mg per 10 mL.

How many mL of medication should the nurse administer to the client?

21.6 mL

26.4 mL

54 mL

64.8 mL

Answer and Explanation

The Correct Answer is A

To calculate the dose of brentuximab in mg that the client should receive, we need to multiply the weight of the client in kg by the prescribed dose of 1.8 mg/kg:.

Dose (in mg) = Weight (in kg) x Dose (in mg/kg).

Dose (in mg) = 60 kg x 1.8 mg/kg. Dose (in mg) = 108 mg.

Now we need to calculate the volume of medication to administer. Since the medication available is 50 mg per 10 mL, we can use proportion to calculate the volume:.

50 mg is to 10 mL as 108 mg is to X mL. 50/10 = 108/X.

Cross-multiplying, we get:. 50X = 108 x 10.

X = (108 x 10)/50. X = 21.6 mL.

Therefore, the nurse should administer 21.6 mL of brentuximab to the client.

Correct Answer is C

Explanation

To calculate the drug dosage, multiply the prescribed dose per kilogram by the client’s weight in kilograms:

0.5 mg/kg x 57 kg = 28.5 mg

A. 75 mL/hr B. 150 mL/hr C. 300 mL/hr D. 450 mL/hr

Correct Answer is C

Explanation

To calculate the rate per hour, divide the amount of magnesium sulfate to be administered by the concentration of magnesium sulfate in the IV bag:

6 grams ÷ 40 grams = 0.15

Then, multiply the result by the volume of the IV bag, which is usually 1000 mL: 0.15 x 1000 mL = 150 mL

This is the amount of fluid that contains 6 grams of magnesium sulfate. To administer this amount over 30 minutes, multiply by 2 to get the rate per hour:

150 mL x 2 = 300 mL/hr.
