A nurse is preparing to administer belimumab 10 mg/kg via intermittent IV bolus to a client who weighs 136 lb. Available is belimumab 80 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["8"]

To calculate the amount of belimumab that the nurse should administer, we can use the following steps:

Convert the patient's weight from pounds to kilograms.

Multiply the patient's weight in kilograms by the dosage of belimumab (10 mg/kg) to find the total dosage required.

Determine the volume of the drug needed using the concentration of the available belimumab solution.

Given:

Patient's weight = 136 lb

Dosage of belimumab = 10 mg/kg

Available concentration of belimumab = 80 mg/mL

Let's calculate step by step:

Convert patient's weight from pounds to kilograms:

Patient's weight in kg = 136 lb × (1 kg / 2.2 lb) ≈ 61.8 kg

Calculate the total dosage required:

Total dosage = 10 mg/kg × 61.8 kg ≈ 618 mg

Determine the volume of the drug needed using the concentration of the available belimumab solution:

Volume of drug = Total dosage / Concentration of belimumab

Volume of drug = 618 mg / 80 mg/mL ≈ 7.7 mL

Rounding to the nearest whole number, the nurse should administer 8 mL of the belimumab.

Correct Answer is ["1.1"]

Explanation

To calculate the amount of cefazolin that the nurse should add to the 50 mL of 0.9% sodium chloride, we can use the following steps:

Calculate the amount of cefazolin needed to prepare the solution:

The concentration to be achieved is 225 mg/mL.
The required dose is 250 mg.

Calculate the volume of cefazolin needed:

250 mg ÷ 225 mg/mL = 1.111... mL
Rounded to the nearest tenth, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride.

Therefore, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride to prepare the solution for IV administration.

Correct Answer is ["0.4"]

Explanation

Given:

Enoxaparin dose: 40 mg

Available concentration: 100 mg/mL

Step 1: Calculate the volume of enoxaparin to be administered in mL

Volume = Enoxaparin dose / Concentration

Volume = 40 mg / 100 mg/mL

Volume = 0.4 mL

Rounding to the nearest tenth:

Volume = 0.4 mL

Therefore, the nurse should administer 0.4 mL of enoxaparin subcutaneously for the prevention of deep vein thrombosis.
