The nurse applies a moisture-retentive dressing to a client's wound. The nurse understands that the main advantage of this dressing, rather than a wet dressing, is its ability to:
Provide autolytic debridement.
Decrease epidermal resurfacing.
Enhance the absorption of topical medications.
Promote the formation of a protective scab that traps excess exudate.
Promote the formation of a protective scab that traps excess exudate.
The Correct Answer is A
Choice A rationale
Autolytic debridement is the natural process by which the body breaks down and removes dead tissue. Moisture-retentive dressings create an optimal environment for this process, facilitating wound healing.
Choice B rationale
Decreasing epidermal resurfacing is not a recognized benefit of moisture-retentive dressings. These dressings aim to promote healing, not inhibit epidermal growth.
Choice C rationale
While moisture-retentive dressings can help with the absorption of topical medications, this is not their main advantage. The primary benefit is creating a conducive environment for autolytic debridement.
Choice D rationale
Promoting the formation of a protective scab that traps excess exudate is not the main advantage of moisture-retentive dressings. In fact, these dressings help manage exudate and reduce the risk of infection without forming a scab.

Correct Answer is B
Explanation
Choice A rationale
A CPP within normal limits ranges from 60 to 80 mm Hg, so a value of 40 mm Hg is not within this range.
Choice B rationale
A CPP of 40 mm Hg is considered low and indicates inadequate cerebral blood flow, which can result in brain ischemia and damage.
Choice C rationale
The reading of 40 mm Hg is considered accurate, as it reflects the current CPP of the client.
Choice D rationale
A CPP of 40 mm Hg is not high but low, indicating compromised cerebral perfusion.
Correct Answer is B
Explanation
Choice A rationale
Cushing triad is a late sign of increased ICP, characterized by bradycardia, hypertension, and irregular respirations, appearing after other symptoms like decreased LOC.
Choice B rationale
Decreased LOC is one of the earliest signs of increased ICP as it reflects the brain's response to pressure changes, alerting the need for immediate intervention.
Choice C rationale
Headache can be an early sign but is not as sensitive or specific as changes in LOC when assessing for increased ICP.
Choice D rationale
Coma is a late sign of significantly increased ICP, indicating severe brain dysfunction, often following initial symptoms like decreased LOC.
