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.

Correct Answer is ["800"]
Explanation
This choice is correct because it is the result of dividing the volume of the bolus (200 mL) by the time of the infusion (15 minutes) and multiplying by 60 minutes per hour. The formula for calculating the rate of the pump is:
Rate = (Volume/Time) x 60
Therefore, the rate of the pump is:
Rate = (200 mL/ 15 min) x 60 = 800 mL/hr
Correct Answer is D
Explanation
Choice A reason: This choice is incorrect because insulin is not commonly given to all hospitalized clients. Insulin is a hormone that lowers blood sugar levels in the body. It is only given to clients who have diabetes or other conditions that cause high blood sugar, such as pancreatitis, sepsis, or steroid therapy. The nurse should explain the indication and purpose of insulin to the client and not make false or misleading statements.
Choice B reason: This choice is incorrect because the client did not likely develop diabetes prior to hospitalization, but are just now being diagnosed. Diabetes is a chronic condition where the body either does not produce enough insulin or does not use it properly, resulting in high blood sugar levels. Diabetes can be diagnosed by measuring the blood sugar levels, the hemoglobin A1c levels, or the oral glucose tolerance test. The nurse should not assume or imply that the client has diabetes without proper testing and confirmation.
Choice C reason: This choice is incorrect because the client did not develop type 1 diabetes and will not need insulin for the rest of their life. Type 1 diabetes is an autoimmune condition where the body destroys the insulin-producing cells in the pancreas, leading to a complete lack of insulin. Type 1 diabetes usually develops in childhood or adolescence, and requires lifelong insulin therapy. The nurse should not diagnose or predict the client's condition without evidence or authority.
Choice D reason: This choice is correct because glucocorticoid steroid medications can cause temporary hyperglycemia. Glucocorticoids are anti-inflammatory drugs that suppress the immune system and reduce inflammation. They are used to treat conditions such as multiple sclerosis, asthma, rheumatoid arthritis, and allergic reactions. However, they can also increase the blood sugar levels by stimulating the liver to produce more glucose and reducing the sensitivity of the cells to insulin. The nurse should inform the client that the insulin is needed to control the blood sugar levels while they are on steroid therapy, and that the insulin dose may be adjusted or discontinued when the steroids are tapered or stopped.
