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","C","D"]
Explanation
Choice A rationale
Tachycardia is not a symptom of Cushing's triad; it is often associated with other conditions such as stress or heart problems.
Choice B rationale
Bradypnea is a hallmark of Cushing's triad, indicating decreased respiratory rate due to increased intracranial pressure.
Choice C rationale
Hypertension is a key component of Cushing's triad, caused by increased intracranial pressure leading to elevated blood pressure.
Choice D rationale
Bradycardia, or a slower than normal heart rate, is a symptom of Cushing's triad, resulting from increased pressure in the brain affecting the heart rate.
Choice E rationale
Pupillary constriction is not typically associated with Cushing's triad; it is usually related to other neurological conditions.
Correct Answer is B
Explanation
Choice A rationale
Temporal lobe damage affects auditory processing and memory rather than visual stimuli interpretation, impacting functions like language comprehension and memory formation.
Choice B rationale
Occipital lobe is the primary visual processing center of the brain, responsible for interpreting visual stimuli. Damage to this lobe impairs visual perception and recognition, aligning with the symptoms described.
Choice C rationale
Frontal lobe injury affects executive functions, behavior, and motor skills, not visual stimuli interpretation. Symptoms include problems with planning, movement, and personality changes rather than visual processing issues.
Choice D rationale
Parietal lobe processes sensory information such as touch, temperature, and pain, and helps in spatial orientation. It does not primarily interpret visual stimuli, making it less relevant to the described visual interpretation difficulty.
