Correct Answer: A

Rationale: The correct answer is A. Expressing that life is without purpose can indicate deepening depression or suicidal ideation, which requires immediate attention. While sweating, fatigue, drowsiness, nausea, and loss of appetite can be side effects of duloxetine (Cymbalta), they do not indicate the same level of urgency as a statement suggesting deepening depression or suicidal ideation.

Correct Answer: A

Rationale: The correct answer is to stay with the client and ensure her safety. Ensuring the client's safety is the top priority when a client expresses suicidal ideation. Staying with the client can help prevent self-harm while further assessment and interventions are arranged. Choice B is incorrect because simply informing the client that she is safe in the hospital does not address the immediate need for safety. Choice C is incorrect as while documentation is important, it is not the priority when a client's safety is at risk. Choice D is also incorrect as encouraging the client to join a group therapy session is not appropriate when the client is in crisis and expressing suicidal thoughts.

Correct Answer: D

Rationale: The correct answer is D because achieving normal electrolyte balance is critical in clients with anorexia nervosa. Electrolyte imbalances can lead to serious, life-threatening complications such as cardiac arrhythmias and organ failure. While establishing normal eating patterns (choice A) and verbalizing feelings about food and weight (choice B) are important aspects of treatment, addressing electrolyte balance takes precedence due to the immediate risks associated with imbalances. Additionally, setting a weight gain goal of 2 pounds per week (choice C) may not be appropriate initially as rapid refeeding can also lead to electrolyte imbalances and other complications.

Correct Answer: B

Rationale: The most important nursing intervention during the first 48 hours for a client with anorexia nervosa is monitoring vital signs and electrolytes (B) to assess for life-threatening complications. This helps in early detection of any physiological imbalances that could lead to serious consequences. Providing high-calorie, high-protein meals (A) is important for nutritional rehabilitation but comes after ensuring the client's physical stability. Encouraging the client to talk about feelings (C) and observing for signs of purging (D) are relevant aspects of care but are not as critical as monitoring vital signs and electrolytes in the initial phase of treatment.

Correct Answer: A

Rationale: The correct answer is A: "It may take 4-6 weeks for the medication to be effective." SSRIs like fluoxetine typically take 4-6 weeks to reach their full effect, so clients should be informed to expect a gradual improvement in symptoms. Choice B is incorrect because fluoxetine is usually taken in the morning to prevent sleep disturbances. Choice C is incorrect as there is no specific need to avoid consuming dairy products while taking fluoxetine. Choice D is incorrect because clients should never stop taking antidepressants abruptly, as it can lead to withdrawal symptoms and worsening of the condition.
