Correct Answer: B

Rationale: The correct answer is to stop the transfusion (Choice B). The symptoms described - chills, headache, and low back pain - are indicative of a transfusion reaction. The priority action is to immediately stop the transfusion to prevent further complications such as more severe reactions like hemolytic reactions or anaphylaxis. Administering acetaminophen (Choice A) may help with symptoms but does not address the underlying cause. Slowing the transfusion rate (Choice C) may not be sufficient if a serious transfusion reaction is occurring. Administering antihistamines (Choice D) is not the priority in this situation; stopping the transfusion takes precedence to ensure patient safety.

Correct Answer: A

Rationale: The correct answer is the hospital ethics committee. This committee is specifically designed to address and resolve ethical conflicts in patient care. It comprises professionals from various disciplines who can provide guidance and support in navigating ethical dilemmas. Choice B, the quality improvement committee, focuses on enhancing the quality of care provided but may not be equipped to handle ethical conflicts. Choice C, the chaplain, offers spiritual and emotional support but may not have the expertise to resolve ethical dilemmas. Choice D, the director of nursing, is responsible for nursing operations and may not be the appropriate resource for addressing ethical conflicts.

Correct Answer: D

Rationale: Corrected Question: When a client with heart failure is prescribed enalapril, monitoring for hyperkalemia is essential. Enalapril is an angiotensin-converting enzyme (ACE) inhibitor that can lead to an increase in potassium levels in the blood. This adverse effect can be serious and potentially life-threatening. Choices A, B, and C are incorrect because enalapril does not typically cause hypertension, hypokalemia, or hyperglycemia as adverse effects. It's essential for healthcare providers to be vigilant in monitoring potassium levels when clients are on ACE inhibitors like enalapril.

Correct Answer: D

Rationale: The recommended approach for handling aggressive behavior in a mental health setting is to maintain eye contact, offer clear choices, and set boundaries. This approach can help de-escalate the situation by establishing communication and structure. Choice A is incorrect as encouraging physical activity may not be suitable during an aggressive episode. Choice B is incorrect because avoiding eye contact can hinder communication and resolution. Choice C is also incorrect as pharmacological interventions should not be the immediate go-to method for managing aggression unless absolutely necessary.

Correct Answer: B

Rationale: The correct answer is B because chest physiotherapy (CPT) helps reduce respiratory infections by loosening mucus in the lungs. Choice A is incorrect because coughing may temporarily increase during CPT treatments as mucus is being cleared. Choice C is incorrect because postural drainage is typically performed before meals. Choice D is incorrect because while CPT can help manage symptoms and improve lung function in COPD, it does not cure the disease.
