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.

Correct Answer is C
Explanation
Choice A reason: This is incorrect. Dry cough and nose bleed are not common side effects of gemfibrozil. They may indicate other conditions, such as allergies, infections, or bleeding disorders.
Choice B reason: This is incorrect. Constipation and dry skin are not common side effects of gemfibrozil. They may be caused by dehydration, dietary factors, or other medications.
Choice C reason: This is correct. Abdominal pain and jaundice are serious side effects of gemfibrozil. They may indicate liver damage, which can be fatal if not treated promptly. The client should report these symptoms to the prescriber immediately.
Choice D reason: This is incorrect. Hirsutism and flatulence are not common side effects of gemfibrozil. They may be associated with hormonal imbalances, digestive disorders, or other causes.
Correct Answer is ["48"]
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.
