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 C
Explanation
Choice A rationale
Tactile agnosia is the inability to recognize objects through touch, not vision. This condition affects the somatosensory cortex, impacting tactile processing.
Choice B rationale
Ataxia involves the loss of full control of bodily movements and coordination, not the inability to identify objects visually. It typically results from cerebellar dysfunction.
Choice C rationale
Visual agnosia is the inability to recognize familiar objects by sight despite having intact visual functioning. This condition often results from damage to the occipital or temporal lobes.
Choice D rationale
Positive Romberg sign indicates balance issues, typically seen when a client sways or falls when standing with eyes closed. It does not pertain to visual recognition deficits.
Correct Answer is B
Explanation
Choice A rationale
The Romberg test does not assess motor ability. Motor ability tests typically involve assessing muscle strength, coordination, and movement.
Choice B rationale
The Romberg test is used to assess balance. It evaluates the client's ability to maintain a steady position with eyes closed, indicating the integrity of the proprioceptive and vestibular systems.
Choice C rationale
The Romberg test does involve coordination, but its primary focus is on balance rather than coordination alone. Coordination tests usually involve tasks requiring fine motor control.
Choice D rationale
The Romberg test does not assess muscle strength. Muscle strength tests involve evaluating the force generated by muscles during contraction.
