Which of the following is NOT a common factor delaying wound healing?

• A. Diabetes with poor glycemic control
• B. Adequate nutrition and hydration
• C. Smoking
• D. Edema

Answer: (B)

Wound healing slows when tissue oxygen delivery, perfusion, and nutrient availability are compromised, or when infection and inflammation run unchecked. Diabetes with poor glycemic control impairs immune cell function and blood flow, which slows healing. Smoking reduces oxygen delivery to tissues through vasoconstriction and carbon monoxide binding, delaying repair. Edema raises interstitial pressure and hinders diffusion of nutrients and oxygen to cells, also delaying healing. Adequate nutrition and hydration, on the other hand, provide the substrates for collagen formation, immune function, and cell replication, supporting wound healing rather than delaying it. So the option describing adequate nutrition and hydration is not a delaying factor.
