Correct Answer: D

Rationale: In this scenario, the client's recent weight loss and subsequent pregnancy could lead to concerns about weight regain and body image. The most appropriate nursing diagnosis is 'Potential Situational Low Self-Esteem (related to fear of weight regain and pregnancy).' This diagnosis reflects the client's potential emotional response to the fear of losing the progress achieved through weight loss and dealing with changes in body image due to pregnancy. Options A and C imply that low self-esteem is already present, which is not supported by the information given. Option B is not as suitable as the client's self-esteem issues are more related to the fear of weight regain and pregnancy, making option D the best choice.

Correct Answer: B

Rationale: When assisting a client in gaining insight into anxiety, it is crucial to explore the events that lead to increased anxiety. By asking the client to describe these events, the nurse can help the client recognize patterns and triggers, leading to a better understanding of their anxiety. Option A is incorrect because it refers to triggers rather than exploring the events leading to anxiety. Option C is incorrect as it focuses on relaxation techniques rather than delving into the root causes of anxiety. Option D is inappropriate as addressing resistive behavior may not foster a supportive therapeutic environment for the client.

Correct Answer: B

Rationale: The correct answer is 'Fainting.' Tricyclic antidepressants can cause fainting and hypotension as adverse effects. Shortness of breath (Choice A) is not a common side effect of tricyclics. Large intestine ulcers (Choice C) are not typically associated with tricyclic antidepressants. Distal muscular weakness (Choice D) is not a common adverse effect of tricyclics but is commonly associated with other medications.

Correct Answer: B

Rationale: In the orientation phase of a nurse-client relationship, the significant event is the identification of transference phenomenon. Transference phenomena are intensified in relationships with authority figures like nurses and physicians. Positive transferences may include a desire for affection and dependency, while negative transferences may involve hostility and competitiveness. It is crucial to recognize and address these transferences before progress and positive changes can be made in the working stage. The other choices are incorrect; the establishment of roles may occur in the working phase, placing the client within their family structure is not a key event in the orientation phase, and client agreement on the nurse's authority is not the primary focus during this phase.

Correct Answer: A

Rationale: When a client becomes extremely somnolent with respiratory depression after being given an opiate drug, the physician is likely to order the administration of naloxone (Narcan). Naloxone is an opiate antagonist that attaches to opiate receptors, blocking or reversing the action of narcotic analgesics. Choices B, C, and D are incorrect. Labetalol is a beta blocker used for hypertension, neostigmine is an anticholinesterase agent used to treat myasthenia gravis and reverse neuromuscular blockade, and thiothixene is an antipsychotic agent used for psychiatric conditions.
