Which cerebral lobe is the largest and controls abstract thought?
Temporal.
Frontal.
Parietal.
Occipital.
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 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 D
Explanation
Choice A rationale
Gently pressing the bones on the neck does not effectively test for neck rigidity, which is a common indicator of meningeal irritation or inflammation. This method may detect tenderness or bony abnormalities but not rigidity.
Choice B rationale
Moving the head toward both sides primarily assesses range of motion and flexibility. While reduced range of motion can be noted, this method doesn't specifically test for the resistance characteristic of neck rigidity.
Choice C rationale
Lightly tapping the lower portion of the neck to detect sensation tests for sensory nerve function but is not relevant to assessing muscle tone or rigidity, which is related to motor nerve and muscular response.
Choice D rationale
Moving the head and chin toward the chest is a proper technique to test for neck rigidity. This maneuver can elicit pain or resistance in cases of meningeal irritation, providing a reliable assessment for rigidity.
