Correct Answer: A

Rationale: The correct answer is A because assessing the structure of the family (who comprises the family) is not the last step in family assessment. The rationale is that understanding the family structure is essential at the beginning of the assessment process to identify key relationships and support systems. Assessing interaction among family members helps to understand dynamics and relationships within the family. Assessing communication is crucial to identify roles and patterns of interaction. Ongoing assessment is necessary as family dynamics can evolve throughout the illness. Therefore, A is false as family structure assessment is an important initial step, not the last step.

Correct Answer: A

Rationale: The correct answer is A: Vaccine. Smallpox is a contagious and potentially deadly disease caused by the variola virus. The smallpox vaccine is the most effective way to prevent and control the spread of smallpox. By obtaining adequate quantities of the smallpox vaccine, the ED nurse manager can protect healthcare workers and the public from contracting the virus in case of a smallpox bioterrorism event. Atropine (B) is used to treat certain types of nerve agent poisoning, not smallpox. Antibiotics (C) are ineffective against viruses like smallpox. Whole blood (D) is not specifically needed for smallpox treatment.

Correct Answer: A

Rationale: The correct answer is A because PE should be suspected in patients with unexplained cardiorespiratory complaints and risk factors for VTE. This is important because PE can present with nonspecific symptoms, making it crucial to consider it in the differential diagnosis. Explanation: 1. PE can present with various symptoms, including dyspnea, chest pain, and hemoptysis, but these are not present in all patients. 2. Bradycardia and hyperventilation are not classic symptoms of PE, as it can present with tachycardia and other respiratory findings. 3. Critically ill patients are actually at higher risk for VTE and PE, so prophylaxis is typically recommended. In summary, choice A is correct because it emphasizes the importance of considering PE in patients with cardiorespiratory complaints and risk factors for VTE, while the other choices contain inaccuracies or incomplete information.

Correct Answer: D

Rationale: The correct answer is D because a patient with a history of fluid overload due to heart failure is at the greatest risk of developing acute kidney injury. Heart failure can lead to decreased kidney perfusion causing acute kidney injury. In this scenario, the patient's fluid overload exacerbates the situation, further compromising kidney function. Choice A is incorrect as aminoglycosides can cause kidney injury but the duration of 6 days is less concerning compared to chronic fluid overload from heart failure in choice D. Choice B is incorrect because controlled hypertension does not directly increase the risk of acute kidney injury. Choice C is incorrect as the patient being discharged 2 weeks earlier after aminoglycoside therapy does not necessarily indicate a higher risk compared to chronic fluid overload.

Correct Answer: C

Rationale: The correct answer is C because inquiring about specific cultural rituals and preferences shows respect for the patient's cultural beliefs and values. By asking about these aspects, the nurse can provide care that aligns with the patient's cultural background, promoting comfort and understanding. This action also demonstrates a commitment to individualized care. Choice A is incorrect because standardized care may not always be culturally appropriate. Choice B is incorrect as avoiding discussions about death can hinder effective communication and support. Choice D is incorrect as advising families to strictly follow hospital guidelines may overlook the importance of cultural considerations in end-of-life care.
