Pharmacology for LPN

Correct Answer: B

Rationale: Oatmeal with fresh fruit is a suitable choice for a client with coronary artery disease on a low-cholesterol diet as it is low in cholesterol and provides heart-healthy benefits. Eggs and bacon, cream of chicken soup, and grilled cheese sandwich are higher in cholesterol and may not be as heart-healthy for this client. Eggs and bacon are high in cholesterol, cream of chicken soup may contain saturated fats, and a grilled cheese sandwich typically contains high amounts of fat and cholesterol, making them less suitable choices for a client with coronary artery disease on a low-cholesterol diet.

Correct Answer: B

Rationale: The correct answer is B. Crossing the legs can further impede blood flow in clients with PAD, worsening symptoms. Avoiding leg crossing helps maintain adequate blood flow and reduces the risk of complications associated with peripheral artery disease. Choices A, C, and D are incorrect because elevating the legs, wearing tight compression stockings, and applying heat can exacerbate symptoms in PAD by restricting blood flow or causing potential harm.

Correct Answer: A

Rationale: Being NPO (nothing by mouth) for 6 to 8 hours before a cardiac catheterization is crucial to prevent complications such as aspiration during the procedure. This helps ensure the safety and accuracy of the test results by minimizing the risk of food or liquid in the stomach interfering with the procedure. Choice B is incorrect because the client will need to lie still during the procedure to ensure its accuracy. Choice C is incorrect as the client is typically required to lie flat for a few hours after the test, not several hours. Choice D is incorrect as the client is usually not allowed to drink fluids immediately before the test to prevent complications.

Correct Answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration can also help reduce the risk of kidney problems associated with metformin use. Choices A, B, and D are incorrect. While it's generally recommended to take metformin with food to reduce stomach upset, monitoring for signs of hypoglycemia is more relevant for other antidiabetic medications, and a metallic taste in the mouth is not a common side effect of metformin.

Correct Answer: B

Rationale: Administering anticoagulants as prescribed is crucial in preventing the complication of pulmonary embolism in clients with deep vein thrombosis. Anticoagulants help prevent the formation of new clots and the enlargement of existing ones, thereby reducing the risk of a pulmonary embolism. Encouraging ambulation as tolerated is beneficial for preventing complications related to immobility, but it is not the primary intervention to prevent pulmonary embolism in this case. Applying cold compresses to the affected area may help with pain and swelling but does not address the prevention of pulmonary embolism. Encouraging the use of incentive spirometry is more relevant in preventing respiratory complications such as atelectasis, not specifically pulmonary embolism.
