Final answer:
Bryant's traction is used for children who weigh less than 20 pounds, and it is essential to match pediatric treatments to a child's size for safety and effectiveness.
Step-by-step explanation:
Bryant's traction is a specific type of skin traction used in pediatrics, particularly for managing certain fractures or orthopedic abnormalities in children. The correct answer is B) Than 20 pounds. This method is generally reserved for younger patients, specifically children who weigh 20 pounds or less. After children surpass this weight, other methods of traction or treatment may be more appropriate due to changes in body size and weight distribution.
Understanding the appropriate age and weight for different pediatric treatments is essential in medicine and healthcare. Bryant's traction takes into account the patient's growth stage to ensure that the treatment is both safe and effective for the child's current size. This careful consideration helps avoid complications that might arise from using a method suited to smaller or lighter children on those who have outgrown the technique.
