Pharmacology for LPN

Correct Answer: A

Rationale: The correct answer is to avoid foods high in vitamin K. Clients taking warfarin (Coumadin) should maintain a consistent intake of vitamin K to keep the medication's effectiveness stable. Foods high in vitamin K, such as leafy greens, can interfere with the anticoagulant effects of warfarin. Therefore, it is crucial for clients to avoid these foods to ensure the therapeutic effects of warfarin. Choices B, C, and D are incorrect because increasing dairy products, limiting fiber intake, or increasing protein intake do not directly impact the effectiveness of warfarin therapy and are not necessary dietary modifications for clients on this medication.

Correct Answer: C

Rationale: Following a cardiac catheterization, a common complication to monitor for is bleeding or hemorrhage at the catheter insertion site. Hemorrhage is a significant concern due to the potential for rapid blood loss, leading to hypovolemic shock and other serious complications. Monitoring for signs of bleeding, such as swelling, hematoma, or drop in hemoglobin levels, is crucial for timely intervention. Hypertension is not a common complication post-cardiac catheterization; instead, hypotension may occur due to vasovagal response or bleeding. Hyperglycemia is not typically associated with cardiac catheterization unless the client has pre-existing diabetes or stress-induced hyperglycemia.

Correct Answer: B

Rationale: Yellow or blurred vision can be a sign of digoxin toxicity. These visual disturbances are concerning as they indicate a potential adverse reaction to the medication. Recognizing this symptom promptly is crucial to prevent serious complications. Increased appetite, increased urination, and diarrhea are not typically associated with digoxin toxicity. Therefore, option B is the correct choice in this scenario.

Correct Answer: B

Rationale: Grilled salmon is the correct choice for a client with coronary artery disease on a low-fat, low-cholesterol diet because it is low in saturated fat and high in omega-3 fatty acids, which are beneficial for heart health. Whole milk, fried chicken, and bacon and eggs are higher in saturated fats and cholesterol, making them less suitable choices for this client. Whole milk is high in saturated fat, while fried chicken and bacon and eggs are sources of both saturated fat and cholesterol, which can negatively impact heart health in clients with coronary artery disease.

Correct Answer: C

Rationale: Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. Hypokalemia is a serious electrolyte imbalance that can cause various cardiac and muscular issues. Therefore, the nurse should promptly report hypokalemia to the healthcare provider for appropriate management. Choices A, B, and D are incorrect because weight gain, dry cough, and increased appetite are not typically associated with furosemide use and are not immediate concerns that require urgent reporting.
