Final answer:
A nurse should teach that morbid obesity is defined as a BMI over 40 and that obesity can lead to numerous health conditions. Incorrect information about average body fat percentage and osteoporosis should be excluded, but the relationship between coronary artery disease and waist size is important to include.
Step-by-step explanation:
When teaching a female adult client who is obese about disease management, a nurse should provide accurate and relevant information. One important aspect to include is that morbid obesity is measured as a BMI over 40. While average body fat percentage for women can vary, the statement that it is 15% is inaccurate, as normal averages are higher than this. Obesity does not directly cause osteoporosis, but it can lead to other health complications such as type 2 diabetes, coronary heart disease, and hypertension, among others. Importantly, coronary artery disease risk does indeed increase with larger waist sizes, and the risk escalates significantly for women with a waist size exceeding 81.28 cm (32 in). Therefore, correct information to be included by the nurse would focus on the relationship between obesity and health risks rather than inaccurate body fat percentages or conditions not directly caused by obesity.
