Which of the following physical manifestations would you expect to assess in a patient suffering with Anorexia Nervosa?
bradycardia, hypotension, hypothermia
tachycardia, hypotension, hypothermia
bradycardia, hypertension, hyperthermia
tachycardia, hypertension, hyperthermia
The Correct Answer is A
A. Bradycardia, hypotension, hypothermia: Severe caloric restriction in anorexia nervosa slows metabolic and cardiovascular function, leading to low heart rate, low blood pressure, and decreased body temperature. These changes reflect the body’s adaptation to prolonged starvation and energy conservation.
B. Tachycardia, hypotension, hypothermia: Increased heart rate is not typical in the early or chronic phases of anorexia nervosa unless dehydration or other medical complications are present. Bradycardia is more commonly observed.
C. Bradycardia, hypertension, hyperthermia: Hypertension and elevated body temperature are not characteristic of anorexia nervosa. Hypotension and hypothermia are more consistent with prolonged malnutrition and decreased metabolic activity.
D. Tachycardia, hypertension, hyperthermia: Elevated heart rate, high blood pressure, and hyperthermia are more consistent with hypermetabolic states or infection rather than anorexia nervosa. These vital sign changes are atypical for chronic starvation.

Correct Answer is D
Explanation
A. "This child has symptoms of the early stages of autistic disorder.": Autism spectrum disorder typically presents with deficits in social communication, repetitive behaviors, and restricted interests rather than hyperactivity alone. Constant motion by itself does not indicate autism.
B. "This child's behavior indicates possible symptoms of oppositional defiant disorder.": Oppositional defiant disorder involves persistent patterns of defiant, disobedient, and hostile behavior toward authority figures. Hyperactivity or inability to sit still is not a defining feature.
C. "This child has symptoms of attention deficit hyperactivity disorder.": While hyperactivity is a hallmark of ADHD, a diagnosis cannot be made based on a single observation or parental report. Comprehensive evaluation over time and across settings is required.
D. "This child's behavior must be evaluated according to developmental norms.": Children’s activity levels vary with age and developmental stage. Comparing behavior to developmental expectations allows identification of typical versus concerning patterns and determines if further assessment is warranted.
Correct Answer is D
Explanation
A. Food is rapidly ingested without proper mastication: Rapid eating may contribute to gastrointestinal discomfort or increased calorie intake, but it does not directly cause dental deterioration or enamel erosion.
B. Poor dental and oral hygiene leads to dental caries: While poor oral hygiene can exacerbate dental problems, enamel erosion in patients who purge is primarily due to chemical exposure rather than hygiene practices alone.
C. Purging causes the depletion of dietary calcium: Purging may affect overall nutritional status, but the loss of calcium is not the direct cause of visible dental erosion. Tooth enamel damage occurs through chemical means rather than mineral depletion.
D. The emesis produced during purging is acidic and corrodes the tooth enamel: Repeated vomiting exposes teeth to gastric acid, which is highly erosive. The acid softens and wears away enamel over time, leading to dental deterioration, sensitivity, and increased risk of cavities.
