Which of the following is a contraindication to applying cooling agents?

• A. Open wound
• B. Healthy skin
• C. Normal sensation
• D. Good circulation

Answer: (A)

When using cooling agents, the goal is to safely reduce pain, edema, and metabolic demand in intact tissue. An open wound disrupts the protective skin barrier and tissue is more susceptible to temperature-related injury. Cooling over a wound can worsen tissue damage, slow healing, and potentially mask signs of complications. Therefore an open wound is a contraindication. Intact skin, normal sensation, and good circulation are compatible with cold therapy, provided you monitor closely and limit duration.
