Psychiatric Assessment and Fundamentals Q 29



A characteristic that would suggest to Nurse Anne that an adolescent may have bulimia would be:
  
     A. Frequent regurgitation & re-swallowing of food.
     B. Previous history of gastritis
     C. Badly stained teeth
     D. Positive body image
    
    

Correct Answer: C. Badly stained teeth

Dental enamel erosion occurs from repeated self-induced vomiting. Patients with bulimia nervosa who purge by vomiting often brush their teeth immediately after purging, which can accelerate dental erosion. The clinician should instruct the patients who persist in vomiting to rinse their mouths with water or fluoride rather than brushing their teeth within 30 minutes of each episode.

Option A: A review of systems in patients with bulimia nervosa demonstrates sore throat, irregular menstruation, constipation, headache, fatigue, lethargy, abdominal pain, and bloating. When conducting a physical exam on a patient with diagnosed or suspected bulimia nervosa, obtain the height, weight, vital signs, and orthostatic blood pressures. It is also necessary to examine a patient’s skin, mouth, and abdomen. A neurological examination is essential to check for primary neurological causes of weight loss or vomiting before diagnosing bulimia nervosa.
Option B: Bulimia nervosa can lead to a variety of general medical complications, including metabolic alkalosis, dehydration, constipation, and cardiac arrhythmias. The most common cause of metabolic alkalosis in patients with bulimia nervosa is fluid volume depletion, for which saline administration is indicated in addition to the cessation of the purging behavior.
Option D: Common physical exam signs associated with bulimia nervosa include hypotension, dry skin, parotid gland swelling, dental erosion, and calluses on the dorsal aspect of the hand (known as “Russel’s sign.”) Bulimia nervosa can also be associated with hair loss, edema, and epistaxis.
