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.

Frontal

Occipital

Temporal

Parietal

Answer and Explanation

The Correct Answer is A

A.   The frontal lobe is responsible for a variety of functions, including personality, behavior, judgment, and emotional regulation. It also plays a key role in problem-solving and decision-making. Changes in these areas, such as the emotional instability (crying and anger) described in the question, are often linked to frontal lobe dysfunction.
B.   The occipital lobe is primarily responsible for visual processing. Damage or issues in the occipital lobe typically affect vision, such as causing blindness or visual disturbances, rather than emotional or behavioral changes like those described in the scenario.
C.   The temporal lobe is involved in processing auditory information, memory, and language. While damage to the temporal lobe can affect memory or speech, it is not primarily responsible for the emotional and personality changes described in the scenario. Temporal lobe damage is more commonly associated with memory loss or issues with speech.
D.   The parietal lobe is responsible for sensory information and spatial awareness. While damage here can lead to problems with spatial orientation or sensation, it is not directly responsible for emotional regulation or changes in personality and behavior like those described in the question.

Correct Answer is C

Explanation

A. While alcohol consumption and stress are risk factors, they are not as directly correlated to heart disease as smoking, hypertension, obesity, diabetes, and high cholesterol.

C. Smoking, hypertension, obesity, diabetes, and high cholesterol. These are well-established major risk factors for heart disease, directly impacting cardiovascular health.

A. Hormonal changes causing vasodilation resulting in hypotension B. Atrophy of the muscles causing venous insufficiency C. Peripheral blood vessels become more rigid producing a rise in systolic blood pressure. D. Narrowing of the inferior vena cava causing, bilateral lower extremities varicosities

Correct Answer is C

Explanation

A. Hormonal changes can occur, but they typically do not cause significant vasodilation or hypotension in the elderly.
B. Atrophy of the muscles causing venous insufficiency. While venous insufficiency can occur in aging, muscle atrophy is not the primary factor in this issue.
C. Peripheral blood vessels become more rigid producing a rise in systolic blood pressure. This is a common and expected finding in the elderly due to arteriosclerosis, leading to increased systolic blood pressure.
D. The inferior vena cava does not typically narrow with age, and varicosities are more likely due to vein elasticity changes, not narrowing.
