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.

Correct Answer is ["83"]
Explanation
To calculate the IV flow rate in drops per minute, we can use the following formula:
IV flow rate (gtt/min) = (Volume to be infused in mL drop factor) / Time in minutes
Given:
Volume to be infused = 250 mL
Drop factor = 10 gtt/mL
Time = 30 minutes
Using the formula:
IV flow rate = (250 mL 10 gtt/mL) / 30 min
IV flow rate ≈ (2500 gtt) / 30 min
IV flow rate ≈ 83.33 gtt/min
Rounding to the nearest whole number, the nurse should set the manual IV flow rate to deliver 83 gtt/min.
Correct Answer is ["2.8"]
Explanation
Convert the patient's weight from pounds to kilograms:
154 lb ÷ 2.2 = 70 kg
Calculate the dose of pentamidine:
4 mg/kg × 70 kg = 280 mg
Determine the volume to be administered:
We have 100 mg/mL concentration of pentamidine.
280 mg ÷ 100 mg/mL = 2.8 mL
Therefore, the nurse should administer 2.8 mL of pentamidine to the client.
