The nurse is assessing a client who has been recently diagnosed with an eating disorder. Which of the following findings during the assessment indicates the client is suffering from bulimia nervosa? (Select all that apply.)
1. Potassium level is 3.3 mEq/L
2. Apical pulse is 56 beats per minute
3. Absent gag reflex
4. Lanugo noted
5. BMI is 17
1, 3
Rationale: Clients who suffer from bulimia nervosa often have low serum levels of potassium and chloride related to laxative abuse and vomiting. They have an absent or poor gag reflex. Their heart rate is more likely to be increased because they often abuse central nervous system stimulants to avoid weight gain. People who have anorexia nervosa will have a decreased heart rate due to a decreased metabolism. Clients with anorexia have BMIs equal to or less than 17.5. People with anorexia nervosa frequently develop a fine hair growth across their body called lanugo.
