Which symptom is most closely associated with the onset of anorexia nervosa?
- A. Excessive eating followed by purging.
- B. Obsession with calorie intake and extreme weight loss.
- C. Compulsive exercising to burn calories.
- D. Binge eating episodes with a lack of control.
Correct Answer: B
Rationale: The correct answer is B because an obsession with calorie intake and extreme weight loss is a hallmark symptom of anorexia nervosa. Individuals with anorexia nervosa typically have a distorted body image and an intense fear of gaining weight. This leads them to restrict their food intake severely, leading to extreme weight loss.
Choice A is incorrect because excessive eating followed by purging is more characteristic of bulimia nervosa, not anorexia nervosa. Choice C is incorrect as compulsive exercising is more commonly associated with another eating disorder called orthorexia nervosa. Choice D is incorrect as binge eating episodes with a lack of control are symptoms of binge eating disorder, not anorexia nervosa.

A victim of rape says, "My family is not very supportive."Â Which belief contributes to a negative family response?
- A. No one asks to be raped.
- B. Rape is an act of aggression.
- C. Rape should not be discussed.
- D. Anyone is a potential rape victim.
Correct Answer: C
Rationale: The correct answer is C: Rape should not be discussed. This belief contributes to a negative family response because it promotes silence and stigma around the topic of rape, leading to lack of support and understanding for the victim. By not discussing rape, the victim may feel isolated, ashamed, and unable to seek help or share their experience. Choices A and B are incorrect as they acknowledge the victim's innocence and the violent nature of rape. Choice D is incorrect as it recognizes the reality that anyone can be a victim, but it does not directly address the issue of discussing rape within the family.
It is a secondary dementia indicated by loss of recent memory and disorientation to time and place.
- A. Alzheimer's disease.
- B. Vascular dementia.
- C. Lewy body dementia.
- D. None of the above.
Correct Answer: A
Rationale: The correct answer is A: Alzheimer's disease. Alzheimer's disease is a common type of dementia characterized by progressive cognitive decline, including loss of recent memory and disorientation to time and place. This is due to the accumulation of amyloid plaques and neurofibrillary tangles in the brain. Vascular dementia (B) is caused by reduced blood flow to the brain, leading to cognitive impairment. Lewy body dementia (C) is characterized by the presence of abnormal protein deposits called Lewy bodies in the brain. Choosing D (None of the above) would be incorrect as Alzheimer's disease specifically matches the description provided in the question.
Impaired environmental interpretation syndrome related to metabolic disorders is a condition that affects how the body processes nutrients and energy.
- A. Impaired environmental interpretation related to metabolic disorders.
- B. Impaired environmental interpretation related to cognitive disorders.
- C. Impaired environmental interpretation related to sensory disorders.
- D. None of the above.
Correct Answer: A
Rationale: The correct answer is A because the term "environmental interpretation" refers to how the body processes external stimuli, which can be affected by metabolic disorders. Choice B is incorrect as cognitive disorders do not directly impact environmental interpretation. Choice C is incorrect as sensory disorders specifically affect sensory processing, not environmental interpretation. Choice D is incorrect as option A accurately reflects the relationship between impaired environmental interpretation and metabolic disorders.
A highly suspicious patient who has delusions of persecution about being poisoned has refused all hospital meals for 3 days. Which of the following interventions would be most appropriate under these circumstances?
- A. Feed the patient via tube, involuntarily via court order if needed.
- B. Offer to taste each food item on the tray yourself while he watches.
- C. Allow the patient to contact a local restaurant to deliver his meals.
- D. Allow him supervised access to use food vending machines in the hospital lobby.
Correct Answer: D
Rationale: Step 1: In this scenario, the patient is refusing hospital meals due to delusions of being poisoned, indicating a lack of trust.
Step 2: By allowing supervised access to food vending machines in the hospital lobby, the patient can choose his own food, promoting autonomy and trust-building.
Step 3: This intervention respects the patient's autonomy while ensuring access to food.
Step 4: In contrast, feeding via tube involuntarily (Option A) violates autonomy, tasting food yourself (Option B) doesn't address the issue of trust, and ordering from a restaurant (Option C) may not be feasible or safe in a hospital setting.
Summary: Option D is the most appropriate as it balances patient autonomy and safety, addressing the refusal of hospital meals effectively.
