Explanation

Excessive weight loss, defined as maintaining a body weight less than 85% of what is expected, is a primary criterion for anorexia nervosa.
Amenorrhea, the absence of menstruation, is a classic physiological sign resulting from the hormonal disruptions caused by severe malnutrition and low body fat.
Abdominal distention, along with constipation and bloating, is a common gastrointestinal symptom due to delayed gastric emptying, a direct result of starvation.

Option B: The weight loss in anorexia nervosa is characteristically severe or significant, not 'mild'. Although a slow pulse (bradycardia) is a correct sign, the inaccuracy of the weight loss description makes this option wrong.
Option C: While compulsive behaviors and intense fear of weight gain are core psychological components of the disorder, nausea is not a specific or primary diagnostic symptom. Patients often suppress feelings of hunger rather than feeling nauseous.
Option D: Patients with anorexia nervosa typically have a slow pulse (bradycardia) due to a lowered metabolic rate as the body tries to conserve energy. An increased pulse (tachycardia) is the opposite of what is expected.

Clinical Relevance

Nursing practice connection: Use the key finding related to Diagnostic criteria and clinical manifestations of Anorexia Nervosa to guide bedside assessment, documentation, and the next nursing action.
Recognizing the specific physical signs of starvation in anorexia nervosa, such as severe weight loss, amenorrhea, and bradycardia, is crucial for early intervention and preventing life-threatening complications.
Nurses must monitor for cardiac arrhythmias and severe electrolyte imbalances, which are significant risks associated with the disorder.
What if? If a patient presents with binge eating and purging but maintains a normal or above-normal body weight, the diagnosis would shift from anorexia nervosa to bulimia nervosa. The key differentiator is the presence of significantly low body weight in anorexia.

How to Approach the Question

First, identify the core concept of the question, which is the 'most specific' signs and symptoms for diagnosing anorexia nervosa.
Recall the hallmark diagnostic criteria for anorexia nervosa, which include significant weight loss, an intense fear of gaining weight, and a disturbed body image, leading to specific physiological consequences.
Evaluate each option against these criteria. Look for the combination that includes the most accurate and defining features.
Eliminate options that contain incorrect information. For example, 'mild weight loss' is incorrect because the weight loss is severe, and an 'increased pulse' is incorrect because bradycardia is expected.
Select the option that best represents the classic triad of physical findings associated with the disorder.
