Correct Answer: A

Rationale: The correct answer is A: Implement environmental modifications to promote sleep hygiene. Delirium is often triggered by environmental factors like noise, light, and disruption of sleep. By optimizing the environment for rest and minimizing stimuli, the patient's delirium can improve. This approach focuses on addressing the root cause rather than just managing symptoms. Choice B is incorrect because antipsychotic medications can worsen delirium and are not recommended as first-line treatment. Choice C is not the priority as ruling out focal deficits may be important but does not directly address the delirium. Choice D is incorrect as benzodiazepines can exacerbate delirium and are not recommended due to their potential to worsen cognitive function.

Correct Answer: C

Rationale: The correct answer is C because independence for the elderly means they have the freedom to make choices and decisions about their own lives. This empowers them to live according to their preferences and values. Choice A is incorrect because it doesn't consider individual circumstances; choice B is important but doesn't capture the essence of independence; choice D is too broad and doesn't specifically address the concept of personal autonomy and agency for the elderly.

Correct Answer: C

Rationale: In a postpartum client who presents with severe abdominal pain, nausea, and vomiting, it is crucial to assess for signs of peritonitis or surgical abdomen. These signs may include rebound tenderness, guarding, rigidity, and fever. Peritonitis is a serious condition that may require immediate surgical intervention. Administering antiemetic medication, encouraging clear fluids, or providing a heating pad may not address the underlying cause of the symptoms and delay appropriate treatment. Assessing for signs of peritonitis or surgical abdomen is crucial for prompt identification and management of the client's condition.

Correct Answer: D

Rationale: The correct answer is D: Temporal lobe. Memory and learning are primarily associated with the temporal lobe, specifically the hippocampus. Damage to this area due to stroke can lead to memory loss and impaired learning capacity. Frontal lobe (A) is involved in decision-making and problem-solving. Parietal lobe (B) is responsible for sensory processing. Occipital lobe (C) is related to visual processing. Therefore, the temporal lobe is the most likely site of brain damage in this scenario based on the symptoms presented.

Correct Answer: C

Rationale: The correct answer is C because encouraging the patient to ask questions and express concerns promotes patient empowerment and active participation in self-care. This approach fosters communication, understanding, and collaboration between the nurse and patient, leading to better medication adherence. Choice A is incorrect as it lacks patient involvement. Choice B is helpful but does not necessarily empower the patient. Choice D is directive and does not encourage active participation or empowerment.
