A client who has suffered a stroke is unable to maintain respiration and is intubated and placed on mechanical ventilator support.

What portion of the brain is most likely responsible for the inability to breathe?

Brain stem.

Parietal lobe.

Occipital lobe.

Frontal lobe.

Answer and Explanation

The Correct Answer is A

Choice A rationale

The brain stem controls vital functions, including respiration. Damage to the brain stem, especially the medulla oblongata, can impair respiratory control, leading to the need for mechanical ventilation.

Choice B rationale

The parietal lobe is responsible for sensory processing and does not directly influence respiratory functions. Damage here would more likely affect sensation and spatial awareness.

Choice C rationale

The occipital lobe is primarily responsible for visual processing. Injury to this area would result in visual deficits rather than impaired respiration.

Choice D rationale

The frontal lobe is involved in cognitive functions, voluntary movement, and speech production, but it does not control respiration. Damage here would affect higher cognitive functions and motor planning.

Correct Answer is B

Explanation

Choice A rationale

The temporal lobe is primarily responsible for processing auditory information and is involved in memory formation. It plays a crucial role in hearing, language comprehension, and storing visual memories. It is not primarily responsible for abstract thought.

Choice B rationale

The frontal lobe is the largest of the cerebral lobes and is primarily involved in higher cognitive functions such as abstract thought, decision-making, problem-solving, and planning. It also plays a significant role in controlling voluntary movements, speech production, and emotional regulation.

Choice C rationale

The parietal lobe is involved in processing sensory information such as touch, temperature, and pain. It plays a role in spatial orientation and perception, as well as integrating sensory input to form a coherent understanding of the environment. It is not the largest lobe nor the one controlling abstract thought.

Choice D rationale

The occipital lobe is primarily responsible for processing visual information. It interprets visual stimuli from the eyes and helps in recognizing objects, shapes, and colors. It is not involved in abstract thought or higher cognitive functions.

A. Provide autolytic debridement. B. Decrease epidermal resurfacing. C. Enhance the absorption of topical medications. D. Promote the formation of a protective scab that traps excess exudate. E. Promote the formation of a protective scab that traps excess exudate.

Correct Answer is A

Explanation

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.
