Correct Answer: D

Rationale: The correct answer is D because the patient with a history of violent behavior poses a potential risk to the nurse's safety. Temporarily withdrawing expressions of warmth is important to establish boundaries and ensure safety. Choice A involves an angry patient, but the risk of violence is higher with a history of violent behavior. Choices B and C do not indicate immediate safety concerns.

Correct Answer: A

Rationale: The correct answer is A because the 19-year-old white female patient standing 2 feet in front of the nurse would likely feel uncomfortable with close personal space. Younger individuals tend to value personal space more and may feel more uncomfortable with proximity. Standing 2 feet away is closer than the social distance zone, leading to potential discomfort. Choice B is incorrect because the 40-year-old African-American male patient is sitting next to the nurse, which indicates a level of comfort with proximity. Choice C is incorrect because the 60-year-old Latin-American female patient who is seated across from the nurse is at a comfortable distance for interaction. Choice D is incorrect because the 82-year-old patient from France who is lying in bed with the nurse sitting next to the bed is likely in a more intimate setting where close personal space is expected.

Correct Answer: C

Rationale: The correct answer is C. It is crucial for healthcare professionals to maintain professional boundaries with patients to ensure ethical practice and prevent potential harm. By telling the patient that the relationship must remain professional, the nurse sets clear boundaries and maintains the integrity of the therapeutic relationship. This approach protects both the patient and the nurse from potential ethical violations. Choice A is incorrect because encouraging the behavior could lead to boundary violations and harm the therapeutic relationship. Choice B is not the most appropriate immediate action as it does not address the situation directly with the patient. Choice D is also not the best course of action as transferring the patient does not address the underlying issue of maintaining professional boundaries.

Correct Answer: B

Rationale: The correct answer is B: Perform a needle thoracotomy with a 14- to 16-gauge catheter needle. Rationale: 1. Tension pneumothorax is a life-threatening emergency where air accumulates in the pleural space, causing lung collapse and increased pressure in the chest. 2. The standard treatment for tension pneumothorax is needle thoracostomy, which involves inserting a large-bore needle into the chest to release the trapped air. 3. In this scenario, Mr. U is in respiratory distress despite receiving high-flow oxygen, indicating a significant problem with ventilation that requires immediate intervention. 4. Performing a needle thoracotomy will rapidly decompress the tension pneumothorax, relieving pressure on the heart and lungs, and improving respiratory function. 5. This action takes precedence over other options such as removing the occlusive dressing, initiating CPR, or calling for intubation equipment, as immediate decompression is crucial in managing tension pneumoth

Correct Answer: A

Rationale: Answer A is correct because active listening involves using nonverbal cues such as leaning forward, focusing on the speaker's face, and nodding slightly to show that you are engaged and understanding the message. Leaning forward demonstrates interest, focusing on the face shows attentiveness, and nodding indicates acknowledgment. These actions encourage the speaker to continue sharing and feel heard. Choices B, C, and D are incorrect: B: Avoiding eye contact can make the speaker feel ignored or disconnected, which goes against the principles of active listening. C: Anticipating what the speaker is trying to say and finishing their sentences is not active listening; it can be seen as interrupting and not allowing the speaker to express themselves fully. D: Asking probing questions and directing the conversation towards obtaining specific information efficiently is not active listening. It can come across as controlling the conversation rather than actively listening to the speaker.
