A client with increased intracranial pressure has a cerebral perfusion pressure (CPP) of 40 mm Hg. This CPP reading is considered:

Low.

Inaccurate.

Within normal limits.

High.

Answer and Explanation

The Correct Answer is A

Choice A rationale

A cerebral perfusion pressure (CPP) of 40 mm Hg is considered low, as the normal range for CPP is typically between 60 and 80 mm Hg. Low CPP can lead to inadequate blood flow to the brain.

Choice B rationale

An accurate CPP reading is crucial for assessing intracranial pressure and cerebral blood flow. A reading of 40 mm Hg is not typically considered inaccurate.

Choice C rationale

A CPP of 40 mm Hg is not within normal limits, as it is significantly below the normal range.

Choice D rationale

A CPP of 40 mm Hg is not high; it is considered low and requires medical attention.

Correct Answer is D

Explanation

Choice A rationale

Interactive dressings are designed to interact with the wound environment to promote healing. These can include dressings that release medication or create an optimal moisture balance. They are not typically used for acutely inflamed and oozing skin lesions.

Choice B rationale

Passive dressings are protective covers that keep the wound clean and protected from external contaminants. They do not have additional properties to manage wound exudate or inflammation.

Choice C rationale

Protective dressings are generally used to shield wounds from further injury or contamination. They do not specifically address the needs of an oozing and inflamed lesion.

Choice D rationale

Occlusive dressings are designed to maintain a moist wound environment, which can aid in the healing of oozing wounds. They can also provide a barrier to external contaminants and help manage exudate effectively, making them suitable for acutely inflamed and oozing lesions.

A. Papule. B. Vesicle. C. Wheal. D. Pustule.

Correct Answer is D

Explanation

Choice A rationale

A papule is a small, raised, solid pimple or swelling on the skin, often forming part of a rash. It does not typically contain pus and is not associated with impetigo, which is characterized by pustules.

Choice B rationale

A vesicle is a small fluid-filled blister on the skin, usually containing clear fluid. Impetigo typically presents with pustules rather than vesicles.

Choice C rationale

A wheal is a raised, itchy area of skin that is often a sign of an allergic reaction. It is not characteristic of impetigo, which involves pustules.

Choice D rationale

Impetigo is a highly contagious bacterial skin infection that usually presents with pustules, which are raised lesions containing pus. These pustules can rupture and form a yellowish crust, which is a hallmark of impetigo.
