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.)
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.

Explanation
To calculate the amount of gentamicin the nurse should administer in milliliters (mL) for a client who weighs 210 lb, we can use the following steps:
Given:
Client's weight: 210 lb
Gentamicin dose: 5 mg/kg
Available concentration: 10 mg/mL
Step 1: Convert the client's weight from pounds (lb) to kilograms (kg)
Client's weight in kg = Client's weight in lb / 2.2
Client's weight in kg = 210 lb / 2.2
Client's weight in kg ≈ 95.45 kg
Step 2: Calculate the total dose of gentamicin required
Total dose = Client's weight in kg × Gentamicin dose
Total dose = 95.45 kg × 5 mg/kg
Total dose = 477.25 mg
Step 3: Calculate the volume of gentamicin to be administered in mL
Volume = Total dose / Concentration
Volume = 477.25 mg / 10 mg/mL
Volume ≈ 47.725 mL
Rounding to the nearest whole number:
Volume ≈ 48 mL
Therefore, the nurse should administer approximately 48 mL of gentamicin via intermittent IV bolus to the client who weighs 210 lb.
Correct Answer is D
Explanation
Choice A reason: This choice is incorrect because fluids should not be limited to 1000 mL daily for a client taking hydrochlorothiazide. Hydrochlorothiazide is a diuretic that causes the body to lose water and salt through urine. Limiting fluids can lead to dehydration, electrolyte imbalance, and kidney damage. The client should drink enough fluids to prevent thirst and dry mouth, and follow the doctor's advice on fluid intake.
Choice B reason: This choice is incorrect because this medication is not best taken at night for a client taking hydrochlorothiazide. Hydrochlorothiazide can cause frequent urination, which can disrupt the sleep cycle and cause fatigue. The client should take this medication in the morning or at least 4 hours before bedtime to avoid nocturia (nighttime urination).
Choice C reason: This choice is incorrect because dairy products should not be avoided while on this medication for a client taking hydrochlorothiazide. Hydrochlorothiazide can lower the level of calcium in the blood, which can cause muscle weakness, cramps, and osteoporosis. Dairy products are a good source of calcium and can help prevent calcium deficiency. The client should consume adequate amounts of calcium and vitamin D, and have their blood calcium level checked regularly.
Choice D reason: This choice is correct because the client should consume high potassium foods such as bananas and oranges while on this medication. Hydrochlorothiazide can lower the level of potassium in the blood, which can cause irregular heartbeat, muscle weakness, and numbness. Potassium-rich foods can help prevent potassium deficiency and maintain normal heart and muscle function. The client should also have their blood potassium level checked regularly and avoid salt substitutes that contain potassium.
