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 C
Explanation
Choice A rationale
Dry gauze is absorbent, but it is not the best option for promoting hemostasis in a heavily draining wound. It may adhere to the wound bed, causing pain and potential damage when removed.
Choice B rationale
Transparent dressings allow for easy monitoring of the wound but do not provide the necessary absorption for heavy drainage. They are also not specifically designed to promote hemostasis.
Choice C rationale
Alginate dressings are made from seaweed derivatives and are highly absorbent, which makes them suitable for wounds with heavy drainage. They also help to promote hemostasis by assisting with blood clot formation, making them an appropriate choice for this scenario.
Choice D rationale
Hydrogel dressings provide moisture to the wound and promote autolytic debridement but are not the best choice for heavy drainage. They do not have the absorptive capacity needed for a wound that is actively bleeding.
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.
