**Question:** Steroid is injurious to wound when given

**Core Concept:** Steroids are a class of hormones that play a significant role in various physiological processes, including inflammation, immune response, and tissue repair. However, their prolonged use can have detrimental effects on wound healing.

**Why the Correct Answer is Right:** Steroids exert their effects through binding to specific receptors, which leads to suppression of the inflammatory response, cellular proliferation, and collagen synthesis. This suppression can lead to impaired wound healing and increased risk of complications, such as delayed healing, increased infection, and scar tissue formation.

**Why Each Wrong Option is Incorrect:**

A. **Option A:** Inappropriate focus on a single aspect (wound healing) without considering the overall effects of steroids on the body.
B. **Option B:** Mentioning the wrong option (inflammation) without explaining its relevance to the overall effect of steroids on wound healing.
C. **Option C:** Focusing on the immunosuppressive effects of steroids without considering their broader implications on wound healing.
D. **Option D:** Mentioning the wrong aspect (collagen synthesis) without discussing its relationship to the overall effect of steroids on wound healing.

**Clinical Pearl / High-Yield Fact:** Prolonged corticosteroid therapy can lead to impaired wound healing, which is a crucial consideration when treating patients with chronic wounds or those undergoing surgical intervention.

**Correct Answer:** B. **Option B:** Mentioning the wrong option (inflammation) without explaining its relevance to the overall effect of steroids on wound healing. Inflammation is a crucial part of the wound healing process, involving cellular recruitment, proliferation, and remodeling. Suppression of inflammation can lead to delayed wound healing and increased risk of infection.
