A 30-year-old firefighter suffers extensive third-degree burns over his arms and hands. This patient is at high risk for developing which of the following complications of wound healing?
**Question:** A 30-year-old firefighter suffers extensive third-degree burns over his arms and hands. This patient is at high risk for developing which of the following complications of wound healing?
A. Infection
B. Delayed healing
C. Contracture
D. Scarring
**Core Concept:** Third-degree burns involve the destruction of the dermal and epidermal layers of the skin, leading to impaired wound healing and increased risk of complications.
**Why the Correct Answer is Right:** Extensive third-degree burns can lead to impaired wound healing due to the destruction of the skin layers responsible for providing structural support, blood supply, and immune protection. These patients are at higher risk for complications as compared to those with first or second-degree burns.
**Why Each Wrong Option is Incorrect:**
A. Infection: While infections can occur in burn wounds, the correct answer (B) focuses on the more severe complications related to impaired wound healing in third-degree burns.
B. Delayed healing: In third-degree burns, the impaired wound healing is already noted, making this option less relevant than the correct answer (C).
C. Contracture: Although contractures can occur in burns, the question specifically focuses on complications related to impaired wound healing, making option C less focused than option C (Contracture).
D. Scarring: While scarring is a possible complication in burn wounds, the correct answer (D) emphasizes the importance of impaired wound healing in third-degree burns, making option D less relevant.
**Why the Correct Answer (C) is Right:** Contractures develop due to the destruction of the dermis, which is responsible for maintaining skin flexibility and elasticity. In third-degree burns, the impaired wound healing leads to impaired skin regeneration, increased risk of contractures, and other complications.
**Clinical Pearl:** Early wound care and management, including debridement, skin grafting, and appropriate antibiotics, are crucial to minimize complications in patients with third-degree burns.
