The nurse places Dakin’s solution in a wound for which purpose?
Chemical debridement
Healing
Phagocytosis
Primary intention
The Correct Answer is A
Choice A rationale
Dakin’s solution is an antiseptic containing sodium hypochlorite, used in chemical debridement to clean wounds and remove dead tissue. It helps to reduce the bacterial load and prepares the wound bed for healing by removing non-viable tissue.
Choice B rationale
While Dakin’s solution aids in the overall healing process by cleaning the wound, it does not directly cause healing. Healing is a complex process involving tissue regeneration and repair, which Dakin’s solution supports indirectly.
Choice C rationale
Phagocytosis is a part of the immune response where cells engulf and digest pathogens and debris. Dakin’s solution does not induce phagocytosis but can reduce the microbial load, making it easier for immune cells to clear the wound.
Choice D rationale
Primary intention refers to the direct healing of a wound with minimal tissue loss, typically through suturing. Dakin’s solution is not used for primary intention but for treating wounds that are already open and require cleaning.

Correct Answer is C
Explanation
Choice A rationale
Filling the pack and refreezing it is part of preparing the ice pack but not a necessary step in the application process itself.
Choice B rationale
Covering the pack with plastic wrap is not recommended as it could potentially cause harm by trapping the cold and leading to frostbite.
Choice C rationale
Using a light cover, such as a thin towel, over the ice pack is necessary to protect the skin while still allowing the cold to reach the injured area effectively.
Choice D rationale
Using small ice cubes is a method to create an ice pack but does not pertain to the application process on the skin.
Correct Answer is C
Explanation
Choice A rationale
Elastic adhesive tape is not the best option for a patient experiencing skin irritation from tape removal because it may cause further irritation when removed.
Choice B rationale
Karaya paste is primarily used as a skin barrier and adhesive for ostomy appliances, not for securing dressings, especially in cases of skin irritation.
Choice C rationale
Montgomery straps are designed for situations where frequent dressing changes are needed. They allow the dressing to be changed without removing the adhesive straps each time, minimizing skin irritation.
Choice D rationale
Paper tape is less irritating to the skin than elastic adhesive tape, but it still requires removal with each dressing change, which can irritate sensitive skin.
