In the school health office you repeatedly see a 16-year-old female for complaints of bloating, fullness in the abdomen, and fatigue. You notice that over the past three months she has lost 14 pounds and is now below her minimal ideal body weight.
 
  When you ask about her eating habits she wants to eat healthy and is now a vegetarian. You suspect: 1. Anorexia nervosa.
   2. Loss of weight due to diet.
   3. Lower weight is common for an athlete.
   4. Natural weight loss in an adolescent due to peer pressure.

Question 2

  a. heart failure.
  b. dehydration.
  c. preeclampsia.
  d. sodium overload.

Answer to Question 1

1

Rationale: Anorexia results from a fear of gaining weight and may result from restrictive eating. A change to healthy eating habits or even following a balanced vegetarian diet should not result in excessive weight loss. Being in good physical condition from engaging in athletics may change weight disposition from adipose tissue to muscle, but should not result in extreme weight loss. Peer pressure is a common underlying cause for weight loss among adolescents, but excessive weight loss is a sign of a medical or psychological problem.

Answer to Question 2

C
After 20 weeks of gestation, marked edema, hypertension, and proteinuria are symptoms of preeclampsia. In nonpregnant individuals, edema may be a sign of heart failure or sodium over-load. Dehydration does not cause edema.
