The nurse is preparing a teaching plan for a client diagnosed with bulimia nervosa. What would be included in the teaching plan?
- A. Change eating locations frequently
- B. Consume no more than 2000 to 3000 calories/day.
- C. Eat alone to concentrate on food intake.
- D. Consume high-caloric foods.
Correct Answer: B
Rationale: Included in the teaching plan should be that the client will consume no more than 2000 to 3000 calories/day divided among three meals plus or minus snacks. There should be a restriction of eating locations. Binging takes place when the client with bulimia is alone and when there is a low potential for being discovered. Consuming low-caloric foods may create less anxiety and reduce the potential for purging.
The nurse is providing a teaching seminar to a group of teenagers on the subject of healthy eating. A scale is used to calculate body mass index (BMI) for each individual participant. A participant asks the nurse if a BMI of 25 is normal.
- A. A BMI of 25 is normal.
- B. The BMI formula does not include ratio of fat to muscle mass.
- C. BMI is just one tool for healthy lifestyle.
- D. Keeping your BMI below 30 is ideal.
Correct Answer: C
Rationale: The healthy interpretation of BMI ranges from 18.5 to 24.9. Knowing that teenagers are very susceptible to eating disorders and desire for thinness, the nurse takes the focus off the number (25) and addresses healthy lifestyle. BMI is only one tool used for anthropometric data collection. Ratio of fat to lean muscle mass is not included in BMI. A BMI of 30 is indicative of obesity and would not be considered ideal.
A nurse is assessing a female client who has recently drastically decreased the amount of food and number of calories consumed each day. Which assessment finding is most indicative of a client who is experiencing severe malnutrition?
- A. Amenorrhea
- B. Weight loss
- C. Body mass index (BMI) of 18
- D. High serum potassium level
Correct Answer: A
Rationale: Severe malnutrition causes the cessation of menstruation in females. Weight loss is expected with curtailing of calories but does not indicate severe malnutrition. BMI of 18 is low and indicates being underweight but not significant for severe malnutrition. In severe malnutrition, potassium levels are dangerously low.
