A nurse is providing care for a patient with anorexia nervosa who has refused to eat. What is the nurse's priority intervention?
- A. Provide a structured meal plan and encourage the patient to eat.
- B. Allow the patient to skip meals to avoid overwhelming them.
- C. Focus on addressing body image concerns before eating.
- D. Monitor the patient's weight closely without intervention.
Correct Answer: A
Rationale: The correct answer is A: Provide a structured meal plan and encourage the patient to eat. This is the priority intervention because patients with anorexia nervosa often have a distorted perception of their body and food intake. By providing a structured meal plan, the nurse can help the patient establish a healthy eating routine. Encouraging the patient to eat is crucial to prevent further malnutrition and complications.
Choice B is incorrect because allowing the patient to skip meals can worsen their condition and reinforce unhealthy behaviors. Choice C is incorrect because addressing body image concerns should be done in conjunction with addressing the patient's nutritional needs. Choice D is incorrect because monitoring weight without intervening to address the underlying issue of refusal to eat is not sufficient in managing anorexia nervosa.
A history reveals that a patient virtually stopped eating 5 months ago and lost 25% of body weight. The nurse says, 'Describe what you think about your present weight and how you look.' Which response would be most consistent with anorexia nervosa?
- A. I'm fat and ugly.'
- B. What I think about myself is my business.'
- C. I'm grossly underweight, but I cover it well.'
- D. None of the above.
Correct Answer: A
Rationale: The correct answer is A. This response is most consistent with anorexia nervosa because it reflects a distorted body image common in individuals with this condition. Anorexia nervosa is characterized by an intense fear of gaining weight and a distorted body image, leading to extreme weight loss and restrictive eating habits. Choice B suggests a lack of insight or denial, which is not typical of anorexia nervosa. Choice C acknowledges being underweight but does not reflect the negative body image associated with anorexia nervosa. Choice D is incorrect as option A aligns with the characteristic body image distortion seen in anorexia nervosa.
The intervention of highest priority for a client with stage 3 Alzheimer's disease is to:
- A. Provide a stimulating environment
- B. Maintain hydration and nutrition
- C. Set limits on behavioral disinhibition
- D. Promote self-care activities
Correct Answer: B
Rationale: The correct answer is B because maintaining hydration and nutrition is crucial for the client's overall well-being and health in stage 3 Alzheimer's. Dehydration and malnutrition can lead to serious complications. Providing a stimulating environment (choice A) may be beneficial but not the highest priority. Setting limits on behavioral disinhibition (choice C) may be challenging due to the progression of the disease. Promoting self-care activities (choice D) may not be feasible as the client's cognitive abilities decline. Maintaining hydration and nutrition is essential for the client's survival and quality of life.
A supervisor observes inconsistency in the psychiatric-mental health nurse's behavior toward a patient; the nurse is unreasonably concerned, overly kind, or irrationally hostile. The most appropriate explanation is that the nurse is displaying:
- A. countertransference
- B. empathic resonance
- C. splitting behavior
- D. transference
Correct Answer: A
Rationale: Countertransference involves the nurse's emotional reactions to the patient based on personal unconscious feelings, leading to inconsistent behavior.
When a victim of sexual assault is discharged from the emergency department, the nurse should:
- A. Notify the patient's family of the event to ensure support for the patient.
- B. Offer to stay with the patient until stability is regained.
- C. Advise the patient to try not to think about the assault.
- D. Provide referral information verbally and in writing.
Correct Answer: D
Rationale: The correct answer is D because providing referral information verbally and in writing ensures that the victim has access to appropriate resources for follow-up care and support. This step is crucial in helping the victim navigate the emotional and physical aftermath of the assault.
A: Notifying the patient's family without the patient's consent could violate the patient's privacy and autonomy.
B: While offering to stay with the patient shows support, it may not always be feasible and may not address the victim's long-term needs.
C: Advising the patient to try not to think about the assault is dismissive of their trauma and does not provide constructive support.
