Correct Answer: B

Rationale: The correct answer is B: Opioid medications given as needed. Opioids are indicated for managing dyspnea and restlessness in palliative care by providing relief from symptoms. They act as potent analgesics and can help decrease the distress associated with difficult breathing and restlessness. Respiratory therapy treatments (A) and incentive spirometry treatments (C) may not address the immediate discomfort caused by dyspnea and restlessness. Increased hydration (D) may not directly alleviate the symptoms and could potentially worsen the patient's discomfort.

Correct Answer: A

Rationale: The correct answer is A: sepsis. Sepsis is the most common cause of acute kidney injury in critically ill patients due to the systemic inflammatory response causing renal hypoperfusion. Sepsis leads to a decrease in renal blood flow, resulting in acute kidney injury. Fluid overload (B) can contribute to renal dysfunction but is not the primary cause in critically ill patients. Medications (C) can cause kidney injury, but sepsis is more prevalent. Hemodynamic instability (D) is a consequence of sepsis and can lead to acute kidney injury, making it an indirect cause.

Correct Answer: B

Rationale: The correct answer is B: Cluster nursing activities so that the patient has uninterrupted rest periods. Rationale: 1. Clustering nursing activities allows for uninterrupted rest periods, essential for improving sleep quality and addressing disturbed sensory perception. 2. Administering sedatives or opioids (Option A) can lead to drug dependence, tolerance, and adverse effects in older adults. 3. Silencing alarms (Option C) compromises patient safety by impeding timely monitoring and response to critical events. 4. Eliminating assessments (Option D) between 0100 and 0600 disregards the necessity of monitoring vital signs and assessing patient condition around the clock.

Correct Answer: C

Rationale: The most appropriate nursing action in this scenario is choice C: Provide support for the patient’s decision and ensure comfort measures. This is because the patient is in hospice care, indicating a focus on comfort and quality of life rather than aggressive treatments. By respecting the patient’s decision and providing comfort measures, the nurse promotes dignity and autonomy. Choices A and B are not suitable as they go against the patient's wishes and may cause distress. Choice D, while important, is not the immediate priority when the patient is not in pain and has chosen to refuse food and fluids. Overall, choice C aligns with the principles of hospice care and prioritizes the patient's comfort and autonomy.

Correct Answer: D

Rationale: Rationale: D is correct because the synergy model focuses on individualized care based on patients' unique needs. This model emphasizes tailoring nursing competencies to address these needs, promoting holistic care. A is incorrect as certification is not a requirement. B involves family inclusion but does not capture the core concept. C mentions collaboration but does not specifically address individualized care.
