Pharmacology for LPN

Correct Answer: A

Rationale: Clients prescribed with warfarin (Coumadin) need to maintain a consistent intake of vitamin K and avoid sudden increases in foods rich in vitamin K as it can interfere with the effectiveness of the medication. Choice A, 'I will avoid eating foods high in vitamin K, like spinach and broccoli,' is the correct statement indicating an understanding of the medication. This choice demonstrates knowledge of the importance of consistent vitamin K intake to prevent fluctuations in warfarin's effectiveness. Choices B, C, and D are incorrect. Choice B suggests a substitution that is not advised without consulting a healthcare provider. Choice C is incorrect as stopping warfarin suddenly can lead to serious health risks. Choice D is unsafe and incorrect since doubling the dose is not the correct action if a dose is missed.

Correct Answer: A

Rationale: Increased shortness of breath with exertion is a concerning symptom in a client with chronic stable angina as it may indicate inadequate oxygen supply to the heart muscle, suggesting a worsening condition. This could be a sign of reduced blood flow to the heart, leading to increased work for the heart during exertion, resulting in increased shortness of breath. Choice B, improved tolerance to activity, is incorrect as it would indicate a positive response to treatment. Choice C, decreased frequency of chest pain, is incorrect as it would also suggest an improvement in the client's condition. Choice D, stable blood pressure readings, are not indicative of a worsening condition in chronic stable angina.

Correct Answer: B

Rationale: Corrected Rationale: Beta blockers are medications that can cause bradycardia by slowing down the heart rate. It is essential to monitor for this side effect in clients receiving beta blockers, as it can lead to serious complications such as decreased cardiac output and hypotension. Choices A, C, and D are incorrect because beta blockers are not expected to cause tachycardia (fast heart rate), hypertension (high blood pressure), or hyperglycemia (high blood sugar levels).

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: B

Rationale: The correct answer is B. A persistent dry cough is a common side effect of ACE inhibitors and should be reported to the healthcare provider. This symptom can indicate a potential issue with the medication that may require adjustment or discontinuation. Choices A, C, and D are incorrect. Taking the medication at bedtime or with meals is not a specific instruction for ACE inhibitors. Increasing potassium-rich foods in the diet is not directly related to ACE inhibitor therapy and may not be suitable for all patients.
