Correct Answer: B

Rationale: The correct answer is B: 'Monitor for signs of bleeding.' Clopidogrel is an antiplatelet medication, not an anticoagulant. Clients taking clopidogrel should be monitored for signs of bleeding due to its antiplatelet effects. Choice A is incorrect because clopidogrel is not an anticoagulant. Choice C is incorrect as clopidogrel should not be stopped abruptly but as directed by a healthcare provider. Choice D is irrelevant since foods rich in vitamin K are more of a concern with anticoagulant medications like warfarin, not antiplatelet medications like clopidogrel.

Correct Answer: A

Rationale: The correct answer is to check INR levels. Before administering warfarin, it is crucial to check the INR levels to ensure they are within the therapeutic range. This helps to prevent complications such as bleeding or clotting. Choice B, administering it with food, is incorrect as warfarin should typically be taken on an empty stomach. Choice C, monitoring blood glucose, is unrelated to the administration of warfarin. Choice D, assessing liver function, is important but not the immediate action required before administering warfarin.

Correct Answer: A

Rationale: The correct answer is to limit intake of processed foods. Processed foods are often high in sodium, which goes against the goal of a low-sodium diet. Fresh fruits and vegetables are recommended for a low-sodium diet due to their natural low sodium content. The use of accessory muscles and monitoring for allergic reactions are not related to dietary modifications for a low-sodium diet.

Correct Answer: A

Rationale: The correct answer is to monitor for withdrawal symptoms. This is a priority because individuals with a history of substance abuse are at risk of experiencing withdrawal symptoms when the substance is no longer used. Monitoring for withdrawal symptoms is crucial to ensure the client's safety and to manage any potential complications related to substance withdrawal. Encouraging social activities, scheduling regular follow-ups, and providing educational materials are also important aspects of care, but they are not as critical as monitoring for withdrawal symptoms in this immediate scenario.

Correct Answer: D

Rationale: The correct answer is D: Airborne. Tuberculosis is spread through small droplets that remain airborne for longer periods, hence requiring airborne precautions. Choice A - Contact precautions are used for diseases spread by direct or indirect contact. Choice B - Droplet precautions are for diseases transmitted by large respiratory droplets that can travel short distances. Choice C - Protective isolation is not necessary for tuberculosis, as it is not spread through contact with the client.
