The wife of a 65-year-old man tells the nurse that she is concerned because she has noticed a change in her husband's personality and ability to understand. He also cries very easily and becomes angry. The nurse recalls that the cerebral lobe responsible for these behaviors is the __________ lobe.
Correct Answer: A
Rationale: The correct answer is A: Frontal lobe. The frontal lobe is responsible for personality, emotional expression, decision-making, reasoning, and problem-solving. Changes in personality, emotional instability, and difficulty with understanding can indicate dysfunction in the frontal lobe. The other lobes (parietal, occipital, temporal) are primarily involved in different functions such as sensory processing (parietal), visual processing (occipital), and memory, language, and auditory processing (temporal). In this case, the symptoms described by the wife suggest a problem with the frontal lobe, making it the correct choice.
