Final answer:
The patient whose weight decreased from 50 kg to 45 kg may be prioritized for admission due to the significant percentage of body weight lost. Other health-related factors should also be considered. Understanding the severity of eating disorders and proper categorization of obesity by BMI is critical for diagnosis and treatment.
Step-by-step explanation:
The choice of which patient should be admitted to an inpatient eating-disorder unit can be subjective and complex. However, from a medical perspective, priority is often given to patients who are most at risk due to their current state. In the context of the weights provided, we might need to consider both the absolute weight loss as well as the percentage of body weight lost. The patient who went from 50 kg to 45 kg has experienced a 10% loss of their body weight, which, proportionally, could represent a more significant health risk than the other options that show less percentage of total body weight loss. It is also essential to consider other factors, such as vital signs, mental status, any comorbid conditions, and how the weight loss has affected their health overall.
Healthcare professionals need to monitor patients with eating disorders closely due to risks such as electrolyte imbalances, mental health issues, and other complications. A person experiencing anorexia nervosa might have been closely depicted in the scenario described, showcasing the extreme weight loss and serious health consequences.
Regarding obesity, morbid obesity is diagnosed with a BMI ≥ 35 kg/m² with health problems or a BMI of ≥ 40 kg/m² but < 45 kg/m², whereas the classification of being underweight, normal weight, or overweight is based on the BMI values provided. The importance of accurate diagnosis and proper treatment can't be overstated, as they are critical steps towards recovery.
