Final answer:
The key intervention for an anorexia nervosa patient at 60% of ideal body weight could include weighing them twice weekly, though a comprehensive care plan would involve multiple elements tailored to the individual's needs. For assessing BMI, categorizations can range from underweight to obese, which can indicate various health and nutritional concerns.
Step-by-step explanation:
The appropriate intervention for a nurse to include in the plan of care for a client with anorexia nervosa who is at 60% of ideal body weight involves multiple aspects. One of the interventions might be 'c. Weigh the client twice weekly.' Regularly monitoring the client's weight is essential to gauge recovery progress and ensure that the treatment plan is effective. However, it is also vital that this is done in a controlled and supportive environment to avoid any unnecessary stress for the client. Other interventions, such as those focused on nutrition, hydration, and vital signs monitoring, may also be needed, but the specifics of these would be tailored to the individual's needs. It is worth noting that recovery from eating disorders like anorexia nervosa generally involves a combination of medical, nutritional, and psychological interventions. Concerning the BMI assessment and associated health concerns: An adult with a BMI of 41 kg/m^2 would be classified as having morbid obesity. An adult with a BMI of 24 kg/m^2 falls within the normal weight range. An adult with a BMI of 17 kg/m^2 is considered underweight. A child with a BMI of 27 kg/m^2 could be overweight or obese, depending on age and growth percentiles. The nutrients that provide energy for the body are carbohydrates, fats, and proteins.
