Neurological System Questions Questions
Question 1 of 4
The nurse will document which reflex is present when there is dorsiflexion of the great toe with fanning of other toes?
Correct Answer: B
Rationale: The Babinski reflex, characterized by dorsiflexion of the great toe and fanning of the other toes, is abnormal in adults and indicates damage to the corticospinal tract. This reflex is normal in infants but disappears as the nervous system matures. Its presence in adults suggests neurological pathology.
Question 2 of 4
A neurologist asks a patient to stick out the tongue. Which cranial nerve (CN) is being tested?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 4
A patient becomes startled when the alarm rings for a fire drill. After reassuring the patient that there is no danger, an assessment is completed. Which finding may be related to a sympathetic response?
Correct Answer: D
Rationale: A sympathetic response, or fight-or-flight reaction, includes decreased gastrointestinal activity, leading to diminished bowel sounds. Wheezing, confusion, and incontinence are not typical sympathetic responses. Understanding the autonomic nervous system helps explain physiological changes during stress.
Question 4 of 4
What is a common neurotransmitter?
Correct Answer: D
Rationale: Acetylcholine, GABA, and serotonin are all common neurotransmitters. Acetylcholine is involved in muscle activation and memory, GABA is an inhibitory neurotransmitter that reduces neuronal excitability, and serotonin regulates mood, appetite, and sleep. The diversity of neurotransmitters allows for complex regulation of nervous system functions.
