Which body part percentage is used for weight estimation in an amputee's arm?

In estimating weight for an amputee's arm, the percentage of a person's total body weight that corresponds to an arm is typically around 5.0%. This value is utilized in clinical settings to help assess nutritional needs, monitor weight changes, and adjust dietary plans for individuals who have experienced limb loss.

Understanding how much weight is represented by each body part is crucial for making accurate assessments and providing appropriate care for amputees. Since the arm accounts for approximately 5% of total body weight, it serves as a useful baseline for those in renal nutrition and related fields when considering weight calculations and adjustments in therapeutic diets.

The percentages mentioned in the other options do not accurately reflect the weight contribution of an amputee's arm and would lead to incorrect estimations. Maintaining accurate estimates ensures that treatment plans are effective and tailored to the individual's needs.
