The nurse is providing an educational workshop about coronary artery disease (CAD) and its risk factors. The nurse explains to participants that CAD has many risk factors, some that can be controlled and some that cannot. What risk factors should the nurse list that can be controlled or modified?

A. Gender, obesity, family history, and smoking

B. Inactivity, stress, gender, and smoking

C. Cholesterol levels, hypertension, and smoking

D. Stress, family history, and obesity

Correct Answer: C
Rationale: Cholesterol levels, hypertension, and smoking are controllable risk factors for CAD. Managing these factors through lifestyle changes and medical interventions can help reduce the risk of developing coronary artery disease.

A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching?

• A. Avoid alcohol while taking this medication.
• B. Take the medication with a full meal.
• C. Increase your intake of high-fiber foods.
• D. Avoid exposure to sunlight.

Correct Answer: A
Rationale: The correct instruction for the client prescribed with methotrexate is to avoid alcohol while taking this medication. Methotrexate can cause liver toxicity, and alcohol consumption can further exacerbate this risk. It is crucial for patients to abstain from alcohol to prevent adverse effects on the liver. Therefore, instructing the client to avoid alcohol is a key component of safe medication use and management of rheumatoid arthritis.

The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct Answer: B
Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?

• A. Prevents indigestion associated with the ingestion of spicy foods.
• B. Binds with phosphorus in foods and prevents absorption.
• C. Promotes stomach emptying and prevents gastric reflux.
• D. Buffers hydrochloric acid and prevents gastric erosion.

Correct Answer: B
Rationale: Sevelamer (RenaGel) binds with phosphorus in foods to prevent its absorption, which is why it should be taken with meals. By taking RenaGel with meals, it can effectively bind with phosphorus from food, reducing the amount of phosphorus absorbed by the body, thus helping to manage hyperphosphatemia in clients with ESRD. Choices A, C, and D are incorrect because RenaGel's primary action is to bind with phosphorus in foods, not related to preventing indigestion, promoting stomach emptying, or buffering hydrochloric acid.

A patient with systemic lupus erythematosus (SLE) is prescribed hydroxychloroquine. What is the most important instruction the nurse should give?

• A. Report any vision changes immediately.
• B. Take the medication with milk.
• C. Avoid high-fat foods.
• D. Increase intake of green leafy vegetables.

Correct Answer: A
Rationale: The correct instruction for a patient prescribed hydroxychloroquine, especially in the context of systemic lupus erythematosus (SLE), is to report any vision changes immediately. Hydroxychloroquine can potentially cause retinal damage, so prompt reporting and ophthalmologic evaluation are essential in preventing irreversible eye complications. Choices B, C, and D are incorrect because they do not address the significant adverse effect of hydroxychloroquine on vision. Taking the medication with milk, avoiding high-fat foods, or increasing intake of green leafy vegetables are not relevant to the primary concern of monitoring for visual changes.
