Correct Answer: A

Rationale: The correct answer is A: Epinephrine. In anaphylaxis, epinephrine is the medication of choice due to its rapid onset of action and ability to reverse severe allergic reactions. It acts by constricting blood vessels, increasing heart rate, and opening airways. This helps counteract the dangerous drop in blood pressure and airway constriction seen in anaphylaxis. Digoxin, theophylline, and furosemide are not appropriate for anaphylaxis as they do not address the immediate life-threatening symptoms of anaphylaxis.

Correct Answer: C

Rationale: The correct answer is C because assessing the patient's pain level is the priority when caring for a patient with a brain tumor about to begin radiation treatments. Pain management is crucial in providing comfort and ensuring the patient's well-being during treatment. Teaching the patient about what to expect and addressing any pain promptly are essential steps in delivering effective care. Padding the side rails (choice A) is important for patient safety, but it is not the priority in this situation. Isolating the patient (choice D) is unnecessary unless there is a specific medical indication. Teaching the patient what to expect (choice B) is important but assessing and managing pain take precedence to ensure the patient's comfort and safety during treatment.

Correct Answer: B

Rationale: The correct answer is B: Disturbed body image. The client's concern about the external fixation device making his leg look ugly indicates a disturbance in his perception of his own body image. This diagnosis focuses on the client's feelings and emotions related to his appearance, which can impact his self-esteem and psychological well-being. Rationale: 1. Impaired physical mobility (A) is not the most appropriate diagnosis in this scenario as the client's concern is related to the appearance of his leg, not his ability to move. 2. Risk for infection (C) is not the best choice because the client's concern is not directly related to the risk of infection but rather to the aesthetic aspect of his leg. 3. Risk for social isolation (D) is not the most suitable diagnosis as the client's concern is more about his own perception of his appearance rather than the potential impact on his social interactions.

Correct Answer: D

Rationale: The correct answer is D because asking the patient about their usual sleep patterns and onset of difficulty resting is crucial to understand the situation fully. This helps to identify any potential underlying issues contributing to the sleep disturbance. Choice A is incorrect as it dismisses the patient's concerns. Choice B is not as effective as directly addressing the patient's sleep issues. Choice C delays the assessment, potentially missing important information. By choosing answer D, the nurse can gather valuable information to address the patient's sleep problem effectively.

Correct Answer: D

Rationale: The correct answer is D because interviewing a client suspected of being a victim of abuse involves critical thinking in assessment by gathering relevant information, analyzing the situation, and making informed decisions. This activity helps identify potential risks and ensures the client's safety. On the other hand, options A and C involve implementing orders and diagnosing conditions, respectively, which are more related to clinical decision-making rather than assessment. Option B focuses on education, which is not directly linked to assessment activities.
