Correct Answer: C

Rationale: Delusions often generate fear and isolation, so the nurse should help the client participate in activities that avoid focusing on the false belief and encourage interaction with others.

Correct Answer: B

Rationale: The correct answer is B: "Report any muscle stiffness or unusual movements immediately." This information is crucial because muscle stiffness or unusual movements may indicate extrapyramidal symptoms (EPS), a potential side effect of risperidone that requires immediate attention. Choice A is less critical as regular blood tests are important but not as urgent as identifying EPS. Choice C is irrelevant as tyramine interactions are not associated with risperidone. Choice D is incorrect as weight gain is more common than weight loss with risperidone.

Correct Answer: B

Rationale: The correct answer is to monitor the client's vital signs and weight. This intervention is crucial in assessing the severity of the client's condition and planning appropriate care. Vital signs and weight monitoring help in evaluating the client's physiological status and identifying any immediate concerns related to anorexia nervosa. Choices A, C, and D are important aspects of care for a client with anorexia nervosa; however, during the initial 24 hours of hospitalization, monitoring vital signs and weight takes precedence as it provides essential data for the client's ongoing management and treatment.

Correct Answer: D

Rationale: A fever (D) may indicate neuroleptic malignant syndrome (NMS), a potentially fatal complication of antipsychotics. The healthcare provider should be contacted before administering the next dose of Haldol. Dizziness when standing (A), shuffling gait and hand tremors (B), and urinary retention (C) are all adverse effects of Haldol that, while concerning, do not pose immediate life-threatening risks compared to the potential severity of NMS indicated by a fever.

Correct Answer: C

Rationale: The correct answer is C because the client's unresponsiveness and inability to cooperate with emetic therapy indicate the need for gastric lavage. Gastric lavage is a procedure used to remove toxic substances from the stomach in cases where the patient is unresponsive or unable to cooperate. Choice A is incorrect as the time of ingestion alone does not indicate the need for gastric lavage. Choice B, although indicating a significant overdose, does not directly necessitate gastric lavage. Choice D is incorrect as it provides information about the possible psychological motivation for repeated suicide attempts, but it is not directly related to the immediate need for gastric lavage in this scenario.
