A female client has a neurological deficit involving the limbic system. Specific to this type of deficit, the nurse would document which of the following information related to the client’s behavior.
A. Is disoriented to person, place, and time.
B. Affect is flat, with periods of emotional lability.
C. Cannot recall what was eaten for breakfast today.
D. Demonstrate inability to add and subtract; does not know who is the president.
Correct Answer: B. Affect is flat, with periods of emotional lability.
The limbic system is responsible for feelings (affect) and emotions. While the limbic system was initially suggested to be the sole neurological system involved in regulating emotion, it is now considered only one part of the brain to regulate visceral, autonomic processes. In general, the limbic system assists in various processes relating to cognition; including spatial memory, learning, motivation, emotional processing, and social processing.
Option A: The cerebral hemispheres, with specific regional functions, control orientation. The frontal lobe further divides into a superior, middle, and inferior frontal gyrus, primary motor cortex, and orbital area. These areas combine to control our executive and motor functions. It controls judgment, problem-solving, planning, behavior, personality, speech, writing, speaking, concentration, self-awareness, and intelligence. The parietal lobe is posterior to the central sulcus and anterior to the parieto-occipital sulcus. This lobe controls perception and sensation. The occipital lobe is posterior to the parieto-occipital sulcus and superior to the tentorium cerebelli. This lobe interprets vision, distance, depth, color, and facial recognition. The temporal lobe is inferior to the lateral fissure and further divides into a superior, middle, and inferior temporal gyrus. This lobe controls language comprehension, hearing, and memory.
Option C: Recall of recent events is controlled by the hippocampus. The hippocampus, parahippocampal region of the medial temporal lobe, and the neocortical association have been shown through the autopsy and imaging studies to be essential for memory processing. Impairment of short-term memory leading up to an inability to form new memories occurs when there is bilateral damage to the above-mentioned regions.
Option D: Calculation ability and knowledge of current events relates to the function of the frontal lobe. The frontal lobe further divides into a superior, middle, and inferior frontal gyrus, primary motor cortex, and orbital area. These areas combine to control our executive and motor functions. It controls judgment, problem-solving, planning, behavior, personality, speech, writing, speaking, concentration, self-awareness, and intelligence.
