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 mL"]

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 D

Explanation

Choice A reason: This choice is incorrect because checking the apical heart rate before taking calcium channel blockers is not necessary for most patients. Calcium channel blockers are a group of medications that relax and widen blood vessels, lower blood pressure, and slow the heart rate. They are used to treat conditions such as hypertension, angina, and arrhythmias. The nurse should check the apical heart rate only if the patient has a history of bradycardia (slow heart rate) or heart block (a problem with the electrical conduction of the heart).

Choice B reason: This choice is incorrect because calcium channel blockers do not cause increased blood pressure, but rather lower it. Blurred vision is not a common side effect of calcium channel blockers, and it may indicate other problems, such as eye infection, glaucoma, or stroke. The nurse should instruct the patient to report any changes in vision, but not to associate them with calcium channel blockers.

Choice C reason: This choice is incorrect because calcium channel blockers do not affect cholesterol levels, and the time of day they are taken does not matter. Cholesterol is a type of fat that circulates in the blood and can build up in the arteries, causing atherosclerosis (hardening and narrowing of the arteries). Cholesterol levels are influenced by diet, exercise, genetics, and other medications, such as statins. The nurse should advise the patient to follow a healthy lifestyle and take any prescribed medications for cholesterol control.

Choice D reason: This choice is correct because grapefruit juice can interact with some calcium channel blockers, such as nifedipine, verapamil, and diltiazem, and increase their blood levels and effects. This can cause serious side effects, such as low blood pressure, dizziness, headache, flushing, and edema (swelling). The nurse should warn the patient to avoid grapefruit juice and any products that contain grapefruit while taking calcium channel blockers.

Correct Answer is ["2500 mL"]

Explanation

The nurse needs to administer 2.5 L of 0.45% sodium chloride IV over 24 hours.

We know that 1 L is equal to 1000 mL.

So, 2.5 L is equal to 2.5 x 1000 mL/L = 2500 mL

Therefore, the nurse should administer 2500 mL over 24 hours.
