Which disorder is associated with persons with a body weight that is normal or even slightly above average?
- A. Pica.
- B. Bulimia.
- C. Obesity.
- D. Anorexia nervosa.
Correct Answer: B
Rationale: The correct answer is B: Bulimia. Individuals with bulimia nervosa typically have a normal or slightly above average body weight due to the cycle of binge eating and purging behaviors. This is because they consume large amounts of food during binges but then engage in compensatory behaviors such as vomiting or excessive exercise to prevent weight gain. In contrast, choices A (Pica) and D (Anorexia nervosa) are associated with low body weight. Choice C (Obesity) is characterized by excess body weight. Bulimia is the only disorder in the list where individuals can have a normal or slightly above average body weight due to the nature of their eating behaviors.

- C. Waxy flexibility"¦continue treatment with antipsychotic drugs
- D. Akathisia"¦administer PRN diphenhydramine (Benadryl) PO
Correct Answer: A
Rationale: The correct answer is A: A dystonic reaction"¦administer PRN IM benztropine (Cogentin). This patient is exhibiting symptoms of acute dystonia, a extrapyramidal side effect of haloperidol. Dystonic reactions are characterized by sustained muscle contractions causing abnormal postures. Benztropine is an anticholinergic medication that helps alleviate these symptoms by blocking the neurotransmitter acetylcholine. Administering benztropine is the appropriate treatment for acute dystonia.
Summary of other choices:
B: Tardive dyskinesia"¦seek a change in the drug or its dosage - Tardive dyskinesia is a side effect that occurs after long-term antipsychotic use, not acutely like in this case.
C: Waxy flexibility"¦continue treatment with antipsychotic drugs - Waxy flexibility is a symptom of catatonia, not a side effect of antipsychotic medications
Which of the following is an effective communication technique that should be included in the teaching plan for the family members of a woman in whom Alzheimer's disease has been diagnosed recently?

Complex language or sentences may be difficult for the patient to comprehend.
Choice B is incorrect because encouraging the client to sit during interactions does not directly relate to effective communication techniques. Choice C is incorrect as changing key words can lead to further confusion and may not aid in understanding. Choice D is incorrect because using hand gestures may not always effectively convey the message and can potentially cause more confusion for individuals with Alzheimer's disease.

Which of the following is the most important initial intervention for a patient with bulimia nervosa?
- A. Provide a structured mealtime environment with supervision.
- B. Encourage the patient to participate in support groups immediately.
- C. Administer antianxiety medications as prescribed.
- D. Assess the patient's family dynamics and home environment.
Correct Answer: A
Rationale: The correct answer is A: Provide a structured mealtime environment with supervision. This is the most important initial intervention for a patient with bulimia nervosa because it addresses the immediate health concern of disordered eating behavior. By providing a structured mealtime environment with supervision, the patient can establish regular eating patterns, learn healthier eating habits, and reduce the risk of purging behaviors. This intervention also helps in restoring proper nutrition and addressing any underlying issues related to food and eating.
Choice B is incorrect because support groups may be beneficial but are not the most critical initial intervention. Choice C is incorrect as antianxiety medications do not directly address the disordered eating behavior. Choice D is also incorrect as assessing family dynamics and home environment is important but not as crucial as addressing the immediate eating disorder symptoms.
