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 D
Explanation
Choice A rationale
Signs of medication overdose in Parkinson's disease typically include hallucinations, confusion, and dyskinesia (involuntary movements), rather than slurred speech and drooling. These symptoms are more associated with disease progression.
Choice B rationale
Increasing the medication dose might help in early or middle stages, but slurred speech and drooling indicate more advanced disease stages. Adjusting the dose might not address these specific symptoms effectively.
Choice C rationale
An exacerbation in Parkinson's disease would typically involve a worsening of existing symptoms like tremors, rigidity, and bradykinesia (slowness of movement). Slurred speech and drooling suggest a more chronic progression rather than an acute exacerbation.
Choice D rationale
In the late stages of Parkinson's disease, symptoms can include significant motor dysfunction, slurred speech, and excessive drooling due to impaired swallowing and muscle control. These are signs of advanced disease progression.
Correct Answer is D
Explanation
Choice A rationale
Fever is typically regulated by the hypothalamus, a part of the brain that controls body temperature. Dysfunction of the lower brain stem does not typically cause fever.
Choice B rationale
Visual disturbances are often related to issues with the visual cortex or optic pathways, which are not part of the lower brain stem.
Choice C rationale
Gait alteration is typically associated with dysfunction in the cerebellum or motor pathways, rather than the lower brain stem.
Choice D rationale
Hypoxia, or decreased oxygen levels, can be a critical concern with lower brain stem dysfunction as the lower brain stem controls vital autonomic functions such as respiration and heart rate.
