Correct Answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.

Correct Answer: D

Rationale: When assessing a client's self-expectations about weight loss, it is crucial to inquire about what the client considers a realistic weekly weight loss goal. This question helps in understanding the client's perception and expectations regarding the weight loss journey, enabling the establishment of achievable goals. Choices A, B, and C do not directly address the aspect of setting realistic goals for weight loss. While questioning about changing eating habits, feelings about losing weight, or the importance of weight loss are relevant, they do not specifically focus on setting achievable goals, which is essential for effective weight management.

Correct Answer: A

Rationale: After a lung resection, such as the removal of the left lower lobe for lung cancer, closed chest drainage is a common post-operative measure to help drain any excess air or fluid from the chest cavity. A tracheostomy is not typically needed for this procedure, so choice B is incorrect. Similarly, a mediastinal tube is not routinely inserted following a left lower lobe lung resection, making choice C incorrect. Percussion vibration and drainage are not indicated for this type of surgery, so choice D is also incorrect. Therefore, the correct answer is closed chest drainage.

Correct Answer: A

Rationale: The correct answer aligns with the ANA's definition of the psychiatric nursing role. According to the ANA, psychiatric nursing is a specialized area of nursing practice that incorporates theories of human behavior as its foundational science and utilizes the self as its essential art. This definition emphasizes the importance of understanding human behavior and leveraging therapeutic communication and relationships to provide effective care for individuals with mental health concerns. Choices B, C, and D are incorrect because they do not accurately represent the ANA-defined role of psychiatric nursing. Psychiatric nurses primarily focus on delivering holistic care, promoting mental health, and supporting individuals with mental health challenges using evidence-based practices and therapeutic interventions.

Correct Answer: D

Rationale: According to the Code of Ethics for Nurses, the nurse should try to make the client as comfortable as possible but refuse to assist in death. It is not within the scope of nursing practice to assist in death, even if requested by the client. Choice A is incorrect as advance directives do not directly relate to the client's request for assistance in dying. Choice B is inappropriate as passing the responsibility to another nurse does not address the ethical dilemma at hand. Choice C is incorrect because instructing the client that only a physician can legally assist in suicide does not address the ethical considerations involved in the request. Therefore, the most appropriate action for the nurse is to provide comfort measures while upholding ethical standards and not participating in ending the client's life.
