Which type of wound debridement is Dakin’s solution used for?
Autolytic debridement
Sharp debridement
Enzymatic debridement
Chemical debridement
The Correct Answer is D
Choice A:
es and moisture to digest necrotic tissue. While Dakin's solution can support this process by maintaining a moist wound environment, it does not directly cause autolytic debridement.
Choice B:
Sharp debridement involves the use of a scalpel, scissors, or other sharp instrument to remove dead tissue. Dakin's solution does not perform this function.
Choice C:
Enzymatic debridement involves the use of a topical application of enzymes to break down necrotic tissue. Dakin's solution does not contain these enzymes.
Choice D:
This is the correct choice. Dakin's solution, a sodium hypochlorite-based solution, is used for chemical debridement¹. It can be used to irrigate the wound bed or as the solution for wet-to-moist dressing, effectively cleansing away wound debris and helping create the ideal environment for healing.

Correct Answer is B
Explanation
Choice A rationale
A contusion, commonly known as a bruise, is characterized by skin discoloration due to trauma that causes bleeding under the skin. It does not result in a raised scar, which is why it is not the correct term to describe the patient's condition.
Choice B rationale
A keloid is an overgrowth of scar tissue that forms at the site of a healed skin injury. Keloids are more common in people with darker skin tones, such as African Americans, and are characterized by a raised, firm, and sometimes itchy or painful scar that extends beyond the original wound boundaries. This description matches the nurse's assessment of the patient's scar.
Choice C rationale
A laceration refers to a deep cut or tear in the skin or flesh. Because the nurse is assessing a scar, not a fresh wound, laceration is not the appropriate term for documentation.
Choice D rationale
A hematoma is a localized collection of blood outside the blood vessels, usually in liquid form within the tissue. This term would not be used to describe a raised scar, making it an incorrect choice for documentation.
Correct Answer is D
Explanation
Choice A rationale
A headache is a nonspecific symptom and can be associated with many conditions. It is not typically indicative of internal hemorrhage, which is more likely to present with hemodynamic changes.
Choice B rationale
While a rising pulse is a sign of internal hemorrhage due to the body’s attempt to maintain cardiac output, the blood pressure would typically fall, not rise, as the blood volume decreases.
Choice C rationale
Lethargy and a falling pulse are signs of decreased cardiac output, but in the case of internal hemorrhage, the blood pressure would usually fall, not rise, due to the loss of blood volume.
Choice D rationale
Restlessness, a rising pulse, and falling blood pressure are classic signs of internal hemorrhage. The body responds to blood loss by increasing heart rate to maintain perfusion, but as volume continues to decrease, blood pressure falls.
