A nurse is providing discharge teaching for a client prescribed warfarin. What should be included in the teaching?

Correct Answer: D

Rationale: The correct answer is D. When a client is prescribed warfarin, they should be educated to report any unusual bleeding or bruising promptly. Choices A, B, and C are incorrect. Avoiding foods rich in vitamin K is not necessary when taking warfarin, as long as intake remains consistent. Warfarin does not need to be taken with meals, and aspirin should not be taken for pain relief due to its blood-thinning effects, which can increase the risk of bleeding when combined with warfarin.

Correct Answer: B

Rationale: The correct recommendation to prevent hypoglycemic episodes in a client with diabetes who reports frequent episodes is to monitor blood glucose levels frequently. By monitoring blood glucose levels, the nurse can make necessary adjustments to insulin dosage and diet to maintain blood sugar levels within the target range. Increasing protein intake (Choice A) is not directly related to preventing hypoglycemia; it is more important to focus on balancing carbohydrates and insulin. Increasing the dose of insulin (Choice C) without proper monitoring can lead to further hypoglycemic episodes. Similarly, reducing carbohydrate intake (Choice D) should be done cautiously as carbohydrates are a main source of energy and sudden reduction can cause hypoglycemia in diabetic patients.

Correct Answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.

Correct Answer: A

Rationale: When a patient is exhibiting signs of acute myocardial infarction (AMI), the priority action is to call for emergency assistance immediately. This ensures that the patient receives prompt and appropriate care, including interventions such as administering oxygen, nitroglycerin, and monitoring cardiac rhythm. Administering nitroglycerin should only be done if prescribed by a healthcare provider after assessment and confirmation of AMI. Monitoring the patient's cardiac rhythm is important but not the initial action needed in this critical situation. Administering oxygen and preparing for an ECG are important interventions but should follow the immediate step of calling for emergency assistance.

Correct Answer: A

Rationale: The correct answer is A. Pursed-lip breathing is a nursing consideration for patients with COPD as it helps improve oxygenation and reduces air trapping. While administering bronchodilators and corticosteroids (choice B) is part of the treatment plan, it is typically done by healthcare providers. Monitoring oxygen saturation and arterial blood gases (ABGs) (choice C) is important but not a direct nursing consideration. Teaching the patient how to use an inhaler (choice D) is relevant but not specific to COPD care.
