Pharmacology for LPN

Correct Answer: B

Rationale: Before administering a beta blocker, it is crucial to check the apical pulse. Beta blockers have the potential to slow down the heart rate, making it essential to assess the pulse rate to ensure it is within the safe range before giving the medication. Checking the serum potassium level (choice A) is important when administering certain medications, but it is not specifically required before giving a beta blocker. Oxygen saturation (choice C) and pupil reaction to light (choice D) are not directly related to monitoring parameters for beta blocker administration.

Correct Answer: B

Rationale: Fresh vegetables are a suitable choice for clients on a low-sodium diet as they are naturally low in sodium and provide essential nutrients. In contrast, canned soup, processed cheese, and pickled vegetables tend to be high in sodium, which is not recommended for individuals with heart failure and on a low-sodium diet. Fresh vegetables are also rich in fiber, vitamins, and minerals, making them a healthier option compared to the other choices provided.

Correct Answer: A

Rationale: The correct instruction to reinforce is to 'Report any chest pain or discomfort to your health care provider.' This is crucial because chest pain post-angioplasty can indicate complications that need immediate attention. Choice A is incorrect because returning to work immediately may not be advisable after angioplasty, as the client needs time to recover. Choice B is incorrect because avoiding all physical activity for 2 weeks may not be necessary; instead, gradual resumption of activities is usually recommended. Choice D is incorrect because aspirin should be taken as prescribed by the healthcare provider, not just when chest pain occurs.

Correct Answer: C

Rationale: The most critical instruction for a client after a myocardial infarction is to continue taking prescribed medications even if they feel well. This is essential in preventing another myocardial infarction or other complications. Discontinuing medications prematurely can be detrimental to the client's recovery and may increase the risk of further cardiovascular events. Choices A, B, and D are incorrect because engaging in sexual activity, physical activity, or returning to work are important aspects of the client's recovery, but not as crucial as ensuring medication compliance to prevent further cardiac issues.

Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.
