A fifty-five year-old man suffered a left frontal lobe CV

The frontal lobe of the brain is responsible for higher-level cognitive functions, including emotional regulation, personality traits, social behavior, decision-making, and judgment, as well as motor function control. A cerebrovascular accident (CVA) involving the left frontal lobe frequently results in noticeable alterations in emotional expression, mood stability, impulse control, and social conduct. While motor deficits can occur if the primary motor cortex is affected, behavioral and personality changes are hallmark manifestations uniquely linked to frontal lobe injury. The nurse must closely monitor the client for emotional lability, agitation, apathy, or uncharacteristic behavioral shifts to ensure safety, tailor therapeutic communication, and provide appropriate supportive care during the recovery phase.

Option B: Hearing functions and auditory processing are localized within the temporal lobes of the brain, not the frontal lobe.

Option C: Visual processing occurs primarily in the occipital lobe, whereas appetite regulation is managed by the hypothalamus within the diencephalon.

Option D: Facial muscle control is regulated by the motor cortex and cranial nerves (CN VII), but emotional and behavioral alterations are primary hallmark symptoms of frontal lobe damage.
