Correct Answer: A

Rationale: Step 1: Electroconvulsive therapy (ECT) is a treatment for severe depression and other mental health disorders. Step 2: Current biological theory suggests that ECT produces changes in brain chemistry, specifically neurotransmitters, leading to improved mood. Step 3: The correct answer (A) aligns with this theory by explaining how ECT impacts brain chemistry to alleviate symptoms. Step 4: Answer B is incorrect as ECT is not used as punishment but as a therapeutic intervention. Step 5: Answer C is incorrect as ECT is not primarily used to interrupt brain impulses causing hallucinations and delusions. Step 6: Answer D is incorrect as ECT does not shock the brain into re-establishing normal electrical patterns but rather affects neurotransmitter levels.

Correct Answer: C

Rationale: The correct answer is C: Medications the patient has recently taken. This information is crucial because certain medications can cause symptoms of delirium or exacerbate confusion in elderly patients. By reviewing the patient's recent medications, healthcare providers can identify potential drug-induced causes of confusion and adjust the treatment accordingly. Choice A (Evidence of spasticity or flaccidity) is incorrect because these symptoms are more related to neurological conditions such as stroke or spinal cord injury, not specifically delirium. Choice B (The patient’s level of motor activity) is not as relevant in distinguishing delirium from other problems as medication history, as motor activity can be influenced by various factors. Choice D (Level of preoccupation with somatic symptoms) is also less relevant compared to medication history in differentiating delirium, as somatic symptoms may not always directly indicate the underlying cause of confusion in elderly patients.

Correct Answer: D

Rationale: The correct answer is D because focusing on the feelings suggested by the delusion can help the patient process and manage their emotions underlying the delusion. By addressing the emotions, the nurse can help the patient gain insight into the delusion and reduce its intensity. Confronting the delusion (A) may lead to resistance and reinforcement. Refuting the delusion with logic (B) may further alienate the patient. Exploring reasons for the delusion (C) may not directly address the emotional component.

Step 6: Answer D is incorrect as ECT does not shock the brain into re-establishing normal electrical patterns but rather affects neurotransmitter levels.

Correct Answer: B

Rationale: The correct answer is B because it emphasizes the nurse's role in actively working with the patient to address interpersonal problems. The nurse's initial role is to provide support and assistance to the patient in resolving their issues collaboratively. Choice A focuses on medical treatment and collaboration with the doctor, not specifically addressing interpersonal problems. Choice C solely emphasizes the role of medications in improving the patient's well-being, neglecting the interpersonal aspect. Choice D suggests passing off the responsibility to other professionals, which contradicts the nurse's initial role as a source of help for the patient. In summary, choice B is correct because it highlights the nurse's active involvement in solving the patient's interpersonal problems.
