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

Answer and Explanation

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 B

Explanation

Choice A reason: This is incorrect because 30 minutes is too long to wait for reassessing a client with chest pain. Nitroglycerin has a rapid onset of action and should relieve chest pain within 5 minutes. If not, the client may need another dose or emergency care.

Choice B reason: This is correct because 5 minutes is the appropriate time to reassess a client after administering nitroglycerin sublingual. The nurse should check the client's blood pressure, heart rate, and pain level. If the pain persists, the nurse should follow the protocol for giving another dose or calling for help.

Choice C reason: This is incorrect because 1 hour is too long to wait for reassessing a client with chest pain. Nitroglycerin has a short duration of action and may need to be repeated every 5 minutes for up to 3 doses. Waiting for an hour may put the client at risk of worsening cardiac ischemia or infarction.

Choice D reason: This is incorrect because 15 minutes is too long to wait for reassessing a client with chest pain. Nitroglycerin should have an effect within 5 minutes. If the pain is not relieved by then, the client may need another dose or emergency care.

Correct Answer is ["150"]

Explanation

To calculate the IV pump rate for the 0.9% sodium chloride 1,200 mL IV to infuse over 8 hours, we can use the following formula:

IV pump rate (mL/hr) = Total volume (mL) / Time (hr)

Using the given values:

Total volume = 1,200 mL

Time = 8 hours

Plugging these values into the formula:

IV pump rate = 1,200 mL / 8 hr

IV pump rate = 150 mL/hr

So, the nurse should set the IV pump to deliver 150 mL/hr to infuse the 1,200 mL of 0.9% sodium chloride over 8 hours.
