According to the material, which restriction applies to an athlete with one kidney?

• A. No contact or collision
• B. Full contact or collision
• C. Requires medical clearance
• D. Not specified

Answer: (A)

Protecting an athlete with one kidney hinges on preventing blunt trauma to the kidneys, which would be especially dangerous with a single kidney. The material prescribes no contact or collision, meaning there should be no activities where direct blows to the torso could occur. This restriction minimizes the risk of kidney injury from hits, contusions, or lacerations, which could have serious or life-threatening consequences when only one kidney is present.
