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 A
Explanation
Choice A rationale
The second stage of wound healing is proliferation, which occurs after the initial hemostasis phase. During proliferation, the wound begins to be rebuilt with new, healthy granulation tissue. This tissue is rich in collagen, which forms a foundation for new tissue growth. Capillaries grow across the wound, bringing oxygen and nutrients that are essential for healing. New skin cells begin to form over this granulation tissue, which is a critical component of the healing process.
Choice B rationale
Maturation is the third and final stage of wound healing. It follows the proliferation stage and involves the remodeling of collagen, which strengthens the tissue and restores its normal function. During maturation, the new tissue slowly gains strength and flexibility. Here, the collagen fibers reorganize, the tissue remodels and contracts, and the healed wound becomes more resilient. This stage can take a long time, sometimes up to a year or more, depending on the wound’s severity and the patient’s overall health.
Choice C rationale
Inflammation is indeed the second stage of wound healing. It is a natural part of the healing process and involves controlling bleeding, preventing infection, and enabling the migration of healing cells to the wound area.
Choice D rationale
Remodeling is the last stage of wound healing, not the second. It occurs after the wound has closed and involves the long-term strengthening and formation of scar tissue.
Correct Answer is B
Explanation
Choice A rationale
A contusion, commonly known as a bruise, is characterized by bleeding under the skin, causing discoloration and swelling. It does not involve a break in the skin and therefore does not match the description of the wound with torn skin tissue.
Choice B rationale
A laceration refers to a deep cut or tear in the skin or flesh. Because the nurse discovered torn skin tissue, this type of wound is consistent with the client’s injury described in the scenario.
Choice C rationale
An abrasion is a wound caused by superficial damage to the skin, usually no deeper than the epidermis. It is typically caused by a scrape against a rough surface and is not associated with torn skin tissue.
Choice D rationale
A puncture is a small hole caused by a long, pointed object, such as a nail or needle. This type of wound usually does not result in torn skin tissue but rather a deeper, more narrow penetration.
