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 D
Explanation
Choice A reason: This choice is incorrect because sulfa allergy is not a priority assessment for the nurse to make prior to giving nifedipine. Sulfa allergy is a hypersensitivity reaction to drugs that contain sulfonamide, such as antibiotics, diuretics, or antidiabetic agents. Sulfa allergy can cause symptoms such as rash, itching, fever, or anaphylaxis. Nifedipine does not contain sulfonamide and does not cross-react with sulfa drugs. The nurse should ask the client about any drug allergies and document them, but sulfa allergy is not relevant to nifedipine.
Choice B reason: This choice is incorrect because aPTT is not a priority assessment for the nurse to make prior to giving nifedipine. aPTT stands for activated partial thromboplastin time, which is a measure of how long it takes the blood to clot. It is used to monitor the effect of anticoagulant drugs, such as heparin, that prevent blood clots. Nifedipine does not affect the blood clotting time and does not interact with anticoagulant drugs. The nurse should check the aPTT only if the client is taking anticoagulant drugs and has signs of bleeding or clotting.
Choice C reason: This choice is incorrect because hemoglobin is not a priority assessment for the nurse to make prior to giving nifedipine. Hemoglobin is a protein in the red blood cells that carries oxygen to the tissues and organs of the body. Hemoglobin levels can be affected by conditions such as anemia, dehydration, or blood loss. Nifedipine does not affect the hemoglobin levels or the oxygen delivery. The nurse should monitor the hemoglobin levels and the signs of anemia, such as fatigue, pallor, or shortness of breath, but they are not related to nifedipine.
Choice D reason: This choice is correct because blood pressure is the priority assessment for the nurse to make prior to giving nifedipine. Nifedipine is a calcium channel blocker that lowers blood pressure and relaxes the blood vessels. It is used to treat conditions such as hypertension, angina, and Raynaud's phenomenon. However, nifedipine can cause side effects such as hypotension (low blood pressure), dizziness, headache, flushing, and edema (swelling). The nurse should check the client's blood pressure before giving nifedipine and withhold the dose if the blood pressure is too low. The nurse should also monitor the client's blood pressure and the signs of hypotension, such as fainting, weakness, or chest pain.
Correct Answer is ["25"]
Explanation
To calculate the IV flow rate in drops per minute (gtt/min) for the administration of clindamycin, we can follow these steps:
First, we need to determine the total number of minutes for the infusion, which is given as 1 hour:
1 hour × 60 minutes/hour = 60 minutes
Next, we calculate the total number of drops needed for the infusion:
The total volume to be infused is 100 mL.
The drop factor is 15 gtt/mL.
100 mL × 15 gtt/mL = 1500 gtt
Calculate the IV flow rate in drops per minute:
1500 gtt ÷ 60 min = 25 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 25 gtt/min.
