What labs would indicate a client may need a prescription for an HMG-CoA reductase inhibitor, such as atorvastatin?
High lipid levels
Blood glucose of 60
Platelets over 150,000
Low INR
The Correct Answer is A
Choice A reason: This is correct because high lipid levels, such as cholesterol and triglycerides, are a risk factor for cardiovascular disease. HMG-CoA reductase inhibitors, also known as statins, lower the production of cholesterol in the liver and reduce the risk of heart attack and stroke.
Choice B reason: This is incorrect because blood glucose of 60 is not related to the need for an HMG-CoA reductase inhibitor. Blood glucose of 60 is below the normal range and may indicate hypoglycemia, which is a low blood sugar level. Hypoglycemia can cause symptoms such as dizziness, confusion, sweating, and hunger.
Choice C reason: This is incorrect because platelets over 150,000 are not related to the need for an HMG-CoA reductase inhibitor. Platelets are blood cells that help with clotting and prevent bleeding. The normal range of platelets is 150,000 to 450,000 per microliter of blood. Platelets over 150,000 are within the normal range and do not indicate a problem.
Choice D reason: This is incorrect because low INR is not related to the need for an HMG-CoA reductase inhibitor. INR stands for international normalized ratio and is a measure of how long it takes the blood to clot. The normal range of INR is 0.8 to 1.2. Low INR means the blood clots faster than normal and may indicate a risk of thrombosis, which is a blood clot in a vein or artery.

Explanation
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 ["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.
