How is muscle tone assessed in the motor examination component of the neurologic exam?
Press to flip
Muscle tone is assessed through inspection, palpation, and functional testing during the motor examination.
What is the primary purpose of the CNIM mock exam according to the lecture notes?
The primary purpose of the CNIM mock exam is to act as a diagnostic tool to assess current knowledge level, identify areas that need improvement, and evaluate progress over time.
What is the significance of the Babinski sign in a reflex examination?
The presence of the Babinski sign may indicate dysfunction of the central nervous system, such as an upper motor neuron lesion.
What does the presence of hyperreflexia indicate in a neurological exam?
Hyperreflexia indicates a possible upper motor neuron lesion.
What are signs of a lower motor neuron lesion as observed in a neurologic exam?
Signs of a lower motor neuron lesion include atrophy, hyporeflexia, and fasciculations.
Which cranial nerves are primarily assessed during a cranial nerve examination?
Cranial nerves 3 through 12 are primarily assessed during a cranial nerve examination.
What is the MRC strength scale used for in the neurologic examination?
The MRC strength scale is used to determine muscle strength during the motor examination.
Why should questions on the mock exam not be answered if completely unsure of the answer?
Unanswered questions prevent skewed results which give a more accurate assessment of actual knowledge.
Why should you focus on keywords when categorizing questions during the mock exam?
Focusing on keywords helps categorize questions into topics like anatomy and guidelines, making it easier to understand and answer correctly.
What are some recommended study techniques for preparing for the CNIM exam?
Recommended study techniques include understanding why answers are correct or incorrect and reviewing central nervous system pathology lectures.
What should guide the neurological examination in clinical practice according to the lecture?
The neurological examination should be guided by patient history and symptoms, focusing on specific structures at risk during procedures.
How do upper motor neuron lesions differ from lower motor neuron lesions in the context of reflexes?
Upper motor neuron lesions are characterized by hyperreflexia, while lower motor neuron lesions are characterized by hyporeflexia.
How does the neurologic exam help in intraoperative neuromonitoring?
The neurologic exam helps prevent false negatives in intraoperative neuromonitoring by assessing preoperative and intraoperative status.
What is the role of the Mental Status component in a neurological exam?
The Mental Status component involves observing the patient's orientation and mental clarity as part of the assessment.
Why is coordination and gait testing important, and why is it not commonly done pre-op?
Coordination and gait testing are important for a comprehensive neurologic exam, but they are not commonly done pre-op because other aspects are prioritized.
