Explanation

Normal saline is the recommended cleansing agent for pressure ulcers because it is a non-cytotoxic solution.
Being isotonic, it has the same salt concentration as body fluids, which prevents damage to the delicate cells required for healing, such as fibroblasts.
It effectively removes wound debris and exudate without causing irritation or disrupting the natural healing process.
Guidelines for wound care consistently advocate for using non-cytotoxic cleaners like normal saline for clean, granulating wounds.

Option A: Hydrogen peroxide (H₂O₂) is a cytotoxic agent. Its oxidizing action damages healthy fibroblasts and new granulation tissue, which are essential for wound repair, thereby delaying the healing process.
Option B: Dettol is a chemical antiseptic that is too harsh for an open wound bed. It is cytotoxic, causes chemical irritation, and impedes the natural healing process.
Option C: Glutaraldehyde is a high-level disinfectant used for sterilizing medical equipment. It is extremely toxic to human tissue and must never be applied to a wound.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Selection of appropriate cleansing solution for pressure ulcers as background academic context rather than a clinical decision trigger.
Choosing the correct cleansing solution is a fundamental nursing responsibility that directly impacts wound healing outcomes, prevents further tissue damage, and enhances patient comfort.
Using an inappropriate, cytotoxic solution can delay healing, increase the patient's risk for a secondary infection, and prolong hospitalization and recovery time.
What if? If the pressure ulcer showed signs of a confirmed, severe infection with a high bacterial load, a healthcare provider might temporarily prescribe a specific antimicrobial wound cleanser. However, once the infection is controlled, care would revert to using normal saline for routine cleaning.

How to Approach the Question

First, identify the core task in the question: selecting a cleaning agent for a 'pressure ulcer'.
Recall the primary principle of healing wound care: the goal is to clean the wound while protecting the new, healthy tissue (granulation tissue and fibroblasts).
Evaluate each option based on its intended use and chemical properties. Categorize them as either gentle (isotonic) or harsh (antiseptic/disinfectant).
Recognize that Normal Saline is an isotonic solution, meaning it matches the body's own fluid composition, making it gentle and non-damaging (non-cytotoxic).
Identify H₂O₂, Dettol, and Glutaraldehyde as chemical agents designed to kill microorganisms. This aggressive action is harmful to the delicate cells involved in healing, making them cytotoxic in this context.
Eliminate the cytotoxic options, as they would impede healing. This process of elimination leaves Normal Saline as the only safe and effective choice for routine cleaning.
