A nurse is preparing to administer voriconazole 6 mg/kg via intermittent IV bolus to a client who weighs 127 lb. Available is voriconazole 5 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 ["69"]
To calculate the amount of voriconazole to be administered, we can follow these steps:
Convert the client's weight from pounds to kilograms.
Calculate the total amount of voriconazole needed based on the client's weight.
Determine the volume of the medication to be administered based on the concentration of the available solution.
Let's proceed with the calculations:
Converting the client's weight from pounds to kilograms:
Client's weight = 127 lb
1 lb ≈ 0.453592 kg
Client's weight ≈ 127 lb 0.453592 kg/lb ≈ 57.61 kg
Calculating the total amount of voriconazole needed:
Voriconazole dose = 6 mg/kg 57.61 kg ≈ 345.66 mg
Determining the volume of the medication to be administered:
Available voriconazole concentration = 5 mg/mL
Volume to be administered = 345.66 mg / 5 mg/mL ≈ 69.132 mL
Rounding to the nearest whole number, the nurse should administer 69 mL of voriconazole.

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 is incorrect because a dry cough is not a common or serious side effect of hydralazine. A dry cough is more likely to occur with angiotensin-converting enzyme (ACE) inhibitors, which are another class of antihypertensive drugs.
Choice B reason: This is incorrect because hydralazine does not cause a low heart rate. In fact, hydralazine can cause a reflex increase in heart rate as a result of lowering the blood pressure. This is why hydralazine is often given with a beta-blocker, which can slow down the heart rate.
Choice C reason: This is incorrect because hydralazine does not interact with birth control. However, the nurse should advise the client to use effective contraception while taking hydralazine, as this medication can cause fetal harm if used during pregnancy.
Choice D reason: This is correct because hydralazine can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, and falls. The nurse should instruct the client to avoid getting up too quickly and to ask for assistance if needed.
