Correct Answer: C

Rationale: The correct answer is C because it addresses the patient's anxiety by providing clear communication and involving the patient in the care process. By explaining the turning procedure, inspecting the skin, and providing comfort through lotion application, the nurse establishes trust and promotes a sense of control for the patient. This approach helps alleviate anxiety by keeping the patient informed and engaged in their care. Choice A is incorrect because limiting family visitation may not directly address the patient's anxiety. Choice B is incorrect as it focuses on routine information rather than directly addressing the patient's anxiety. Choice D is incorrect because suctioning the endotracheal tube may cause discomfort and does not address the underlying anxiety issue.

Correct Answer: B

Rationale: The correct answer is B: Caring practices. In this situation, the patient and her husband are dealing with complex medical conditions and emotional distress. Caring practices involve providing compassionate, empathetic, and supportive care to the patient and her family members during this difficult time. The nurse needs to show sensitivity, understanding, and emotional support to help them cope with their situation. Clinical judgment (A) is important but not the primary focus in this scenario. Collaboration (C) is essential in the interdisciplinary team, but caring practices take precedence in addressing the emotional needs. Response to diversity (D) is also important, but in this case, the focus is more on providing compassionate care rather than addressing cultural or social diversity issues.

Correct Answer: B

Rationale: The correct answer is B: Hypoventilation and respiratory acidosis. When a patient overdoses on sedatives, it can lead to respiratory depression causing hypoventilation. Hypoventilation results in retention of CO2, leading to respiratory acidosis. This is because the body is not effectively exhaling CO2, causing an increase in carbonic acid levels and a decrease in blood pH. The other choices are incorrect because hyperventilation would lead to respiratory alkalosis (Choice A), hypoventilation does not cause respiratory alkalosis (Choice C), and normal oxygen levels do not indicate the acid-base imbalance caused by sedative overdose (Choice D).

Correct Answer: A

Rationale: Rationale: A: Education on protection of human subjects is crucial for nurses to understand ethical principles when conducting research studies. It ensures compliance with ethical guidelines and protection of research participants. B: Participation of staff nurses on ethics committees is not directly related to conducting research studies and may not specifically involve protection of human subjects. C: Written descriptions of how nurses participate in ethics programs do not necessarily focus on research studies and may not cover the specific ethical considerations required in research. D: Written policies and procedures related to response to ethical issues are important but may not provide the necessary knowledge on protection of human subjects for conducting research studies.

Correct Answer: B

Rationale: The correct answer is B: Intravenous fluids. In the scenario of a small bowel obstruction, a PAOP of 1 mm Hg indicates hypovolemia requiring fluid resuscitation to improve cardiac output and tissue perfusion. The low urine output suggests inadequate renal perfusion, further supporting the need for fluids. Diuretics (choice A) would worsen the hypovolemia. Negative inotropic agents (choice C) decrease cardiac contractility, which is not indicated in this scenario. Vasopressors (choice D) are used for hypotension, not for hypovolemia. Therefore, the most appropriate intervention is to administer intravenous fluids to address the hypovolemia and improve tissue perfusion.
