Which cerebral lobe is the largest and controls abstract thought?

Temporal.

Frontal.

Parietal.

Occipital.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

Choice A rationale

A CPP of 40 mm Hg is considered low and indicates inadequate cerebral perfusion pressure, which requires immediate medical intervention.

Choice B rationale

A low CPP indicates compromised cerebral blood flow, leading to potential brain ischemia and damage.

Choice C rationale

A reading of 40 mm Hg is not inaccurate if it reflects the actual CPP of the client.

Choice D rationale

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

A. Dysfunction of the spinal accessory nerve. B. Dysfunction of the acoustic nerve. C. Dysfunction of the facial nerve. D. Dysfunction of the vagus nerve. E. Dysfunction of the vagus nerve.

Correct Answer is D

Explanation

Choice A rationale

The spinal accessory nerve (cranial nerve XI) controls the sternocleidomastoid and trapezius muscles, which are responsible for movements of the head and shoulders. Dysfunction in this nerve would not affect the gag reflex.

Choice B rationale

The acoustic nerve (cranial nerve VIII) is responsible for hearing and balance. Dysfunction in this nerve would lead to hearing loss and balance issues, not an absent gag reflex.

Choice C rationale

The facial nerve (cranial nerve VII) controls muscles of facial expression and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. Dysfunction here results in facial paralysis or weakness but not in the absence of a gag reflex.

Choice D rationale

The vagus nerve (cranial nerve X) innervates muscles of the pharynx and larynx, which are involved in swallowing and the gag reflex. Dysfunction in the vagus nerve would result in an absent gag reflex, which is why the nurse determines this as the issue.
