A nurse is caring for a preschooler who has a gastrostomy tube. Which of the following actions should the nurse take?

The nurse must prioritize skin integrity around the gastrostomy tube. This involves understanding gastric acid irritation and appropriate cleansing techniques to prevent chemical dermatitis or infection. Knowledge of pediatric skin care and gastrostomy site maintenance is essential for safe nursing practice. Choice A rationale . Transparent dressings trap moisture and heat against the skin, promoting fungal growth and maceration. This environment increases the risk of infection and skin breakdown. Breathable dressings or leaving the site open to air is generally preferred for healing. Choice B rationale . Barrier ointments, such as zinc oxide, protect the peristomal skin from corrosive gastric secretions. These fluids contain digestive enzymes that cause rapid epidermal breakdown. Providing a physical barrier prevents moisture-related skin damage and keeps the surrounding area intact. Choice C rationale . Hydrogen peroxide is cytotoxic and destroys healthy granulation tissue, significantly delaying the healing process. Routine cleaning should be performed with mild soap and water or normal saline. Avoiding harsh chemicals preserves the integrity of the newly forming skin. Choice D rationale . Tension on the gastrostomy tube can cause pressure necrosis of the gastric mucosa and the abdominal wall. Excessive pulling also increases the risk of tube displacement. The tube should be secured loosely to allow for slight natural movement.
