Which practice helps prevent tissue death during cryotherapy?

• A. Be aware of other impairments
• B. Never apply for > 20 minutes
• C. Perform frequent skin checks
• D. Use heating agent first

Answer: (C)

Monitoring the skin during cryotherapy is essential to prevent tissue death because frostbite can develop before you notice problems. Regular skin checks let you spot early warning signs—paleness or a waxy appearance, numbness, tingling, or loss of sensation—and you can halt or adjust treatment before irreversible damage occurs. While considering patient factors and following protocol timings matters, the key protective step is frequent, real-time observation of the treated area. The other options don’t directly guard against tissue death: being aware of other impairments helps overall safety but doesn’t catch frostbite in progress; a fixed time limit isn’t reliably safe for every individual or situation; and applying a heating agent first counteracts the purpose of cooling.
