A nurse is performing a neurological assessment on a client at home. During the assessment, the nurse notices that the client has a flat affect.
Which lobe of the brain is responsible for a person's affect?
Frontal lobe.
Occipital lobe.
Parietal lobe.
Temporal lobe.
The Correct Answer is A
Choice A rationale
The frontal lobe is responsible for various high-level cognitive functions, including the regulation of emotions and affect. It plays a crucial role in personality expression, decision-making, and moderating social behavior. Damage or dysfunction in the frontal lobe can lead to changes in personality and affect, including a flat affect.
Choice B rationale
The occipital lobe is primarily responsible for processing visual information. It is located at the back of the brain and is not involved in regulating emotions or affect. Therefore, it does not play a role in the client’s flat affect.
Choice C rationale
The parietal lobe is involved in processing sensory information such as touch, temperature, and pain. It also plays a role in spatial orientation and motor control. However, it is not directly involved in regulating emotions or affect. Thus, it does not contribute to the client’s flat affect.
Choice D rationale
The temporal lobe is involved in processing auditory information and is critical for memory and language comprehension. While it plays a role in emotion processing, it is not the primary lobe responsible for affect. The frontal lobe has a more direct impact on emotional regulation and affect.

Correct Answer is B
Explanation
Choice A rationale
Dysfunction in the cerebrum would likely result in different types of posturing, such as decorticate posturing, rather than decerebrate. The cerebrum is involved in controlling voluntary motor functions and damage here typically does not lead to decerebrate posturing.
Choice B rationale
Dysfunction in the brain stem results in decerebrate posturing, characterized by rigid extension of the arms and legs, downward pointing of the toes, and backward arching of the head. The brain stem is crucial for controlling basic life functions and its impairment leads to severe motor response issues.
Choice C rationale
Dysfunction in the spinal column typically does not lead to decerebrate posturing but may lead to different types of paralysis or movement issues depending on the location and severity of the damage.
Choice D rationale
Dysfunction in the motor cortex usually leads to abnormalities in voluntary movement, muscle tone, and coordination rather than decerebrate posturing which is more linked to brain stem issues.
Correct Answer is B
Explanation
