A CVA (stroke) patient goes into respiratory distress and is placed on a ventilator. The client's daughter arrives with a durable power of attorney and a living will that indicates there should be no extraordinary life-saving measures. What action should the nurse take?

Correct Answer: B

Rationale: In this situation, the nurse should notify the healthcare provider. The healthcare provider needs to be informed to review the legal documents provided by the patient's daughter, such as the durable power of attorney and living will, which specify the patient's wishes regarding life-saving measures. The healthcare provider will be responsible for making the appropriate decision based on the legal documents and the patient's current condition. Referring to the risk manager (choice A) is not necessary as the issue at hand pertains to the patient's medical care. Discontinuing the ventilator (choice C) without healthcare provider input could go against the patient's wishes and legal documents. Reviewing the medical record (choice D) may not provide immediate guidance on the current situation and the patient's preferences regarding life-saving measures.

Correct Answer: D

Rationale: Before providing care to an anxious client, it is crucial for the nurse to first re-assess the client's situation. By re-assessing, the nurse can understand the underlying cause of the client's anxiety, which will help in tailoring appropriate care interventions. Re-assessment ensures that care provided is individualized and addresses the client's specific needs, promoting effective and client-centered care delivery. Diverting the client's attention (Choice A) may not address the root cause of the anxiety. Calling for additional help (Choice B) may be necessary in some situations but should not be the first action. Documenting the planned action (Choice C) should come after re-assessing the client's situation to ensure accurate documentation based on the current assessment.

Correct Answer: B

Rationale: An irregular heart rate is a critical sign of hyperkalemia, a serious condition that can lead to life-threatening cardiac arrhythmias. Stopping the infusion promptly is crucial to prevent further complications. The healthcare professional should inform the healthcare provider immediately for further evaluation and management. Choice A is incorrect because pain at the IV site is common and may not necessitate stopping the infusion. Choice C is incorrect as swelling at the IV site may indicate a local reaction but is not a reason to stop the infusion. Choice D is incorrect as an elevated blood pressure alone is not a direct indication to stop the infusion of IV potassium chloride.

Correct Answer: B

Rationale: Monitoring the client's respiratory rate and effort is essential to evaluate the effectiveness of oxygen therapy and prevent complications such as respiratory depression. This intervention helps the nurse promptly detect any deterioration in the client's respiratory status and take necessary actions to ensure the client's safety. Encouraging continuous oxygen use (Choice A) may lead to oxygen toxicity. Setting the oxygen flow rate at a specific level (Choice C) without individual assessment can be inappropriate and potentially harmful. Teaching the client to avoid wearing wool blankets (Choice D) is unrelated to the safe use of oxygen therapy.

Correct Answer: B

Rationale: Engaging in moderate exercise for 30 minutes daily is a crucial lifestyle modification for managing hypertension. Regular physical activity helps lower blood pressure, improve cardiovascular health, and overall well-being. It is recommended to engage in activities like brisk walking, cycling, or swimming to achieve these benefits. Choices A, C, and D are incorrect. Limiting sodium intake, avoiding a diet high in saturated fats, and reducing alcohol consumption are also important lifestyle modifications for hypertension management, but engaging in moderate exercise is the most appropriate initial instruction for this client.
