Choose the right Sequence of Wound healing process?

Appeared in: PGIMS Rohtak NO - 2017

Explanation

The correct sequence of wound healing involves four overlapping phases: Haemostasis, Inflammatory, Proliferative, and Maturation.
Haemostasis is the immediate response to injury, where blood vessels constrict and a clot forms to stop bleeding.
The Inflammatory phase follows, characterized by the arrival of white blood cells (neutrophils and macrophages) to clean the wound of debris and bacteria.
The Proliferative phase is the rebuilding stage, involving the formation of new blood vessels (angiogenesis), granulation tissue, and collagen deposition to fill the wound.
The final Maturation (or Remodeling) phase involves the reorganization of collagen to increase the tensile strength of the scar, a process that can last for more than a year.

Option A: This option incorrectly places the inflammatory phase after maturation. The inflammatory response is an early event that must occur before tissue rebuilding and maturation.
Option C: This option incorrectly starts with the proliferative phase. The body must first control bleeding (haemostasis) and clean the wound (inflammation) before it can begin to rebuild tissue.
Option D: This option incorrectly places haemostasis as the third step. Haemostasis is the immediate, initial response to injury to prevent blood loss.

Clinical Relevance

Nursing practice connection: Knowing Phases of Wound Healing helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A nurse's understanding of the healing stages is crucial for accurate wound assessment and choosing appropriate dressings and interventions for each phase.
Factors like infection, poor nutrition (especially low protein and vitamin C), and inadequate blood supply can delay or stall the healing process, requiring specific nursing interventions like nutritional support and infection control.
What if? If a wound in the proliferative phase shows signs of a new infection (e.g., increased purulent drainage, erythema), the healing process will revert to the inflammatory phase. This significantly delays closure and requires prompt antimicrobial intervention.

How to Approach the Question

This is a factual recall question about a fundamental physiological process.
First, identify the keywords in the question: 'right Sequence' and 'Wound healing'.
Recall the logical order of events that occur after an injury. The first priority is always to stop the bleeding.
Step 1: Stop bleeding (Haemostasis).
Step 2: Clean the area of debris and prevent infection (Inflammatory).
Step 3: Rebuild the damaged tissue (Proliferative).
