Neurological System Questions Questions
Question 1 of 9
Describe the structure of the spinal cord:
Correct Answer: C
Rationale: Spinal cord: grey matter inside (nuclei), white matter outside (tracts), dorsal root sensory. [Level: Knowledge]
Question 2 of 9
Which action can the RN delegate to the unlicensed assistive personnel to reduce fatigue for a patient recovering from a stroke at mealtimes?
Correct Answer: C
Rationale: UAP can cut food, aiding energy conservation. A requires skill, B/D are RN/UAP but less fatigue-specific. [Level: Application]
Question 3 of 9
Which neuroglial cells are involved in the production and circulation of cerebrospinal fluid in the central nervous system?
Correct Answer: D
Rationale: Ependymal cells line ventricles and produce/circulate CSF in the CNS. [Level: Knowledge]
Question 4 of 9
Muscle tissue is innervated by both the somatic motor and autonomic nervous systems. Which type(s) of muscle tissues is(are) innervated by the autonomic nervous system?
Correct Answer: D
Rationale: The autonomic nervous system (ANS) controls involuntary muscles. Skeletal muscle is somatic (voluntary), while smooth and cardiac muscles are involuntary and ANS-innervated. Thus, D is correct. [Level: Knowledge]
Question 5 of 9
A 34-year-old woman presents with neck pain. She is accompanied by her husband, who says she appears to have right-turning, tremor-like movement of the neck. The patient describes the pain as muscle spasm-like, and states that her symptoms improve with rest and sleep. She has recently begun taking Citalopram due to being diagnosed with major depressive disorder. She denies any alcohol or illicit drug use. On physical examination, there is right head turning with left lateral head tilt. Jerky head tremor is noted, with spasm and hypertrophy of the left sternocleidomastoid muscle. Which of the following is most likely the diagnosis?
Correct Answer: B
Rationale: Sustained neck posturing (torticollis) with spasms and hypertrophy suggest cervical dystonia, possibly drug-induced (citalopram). Myoclonus is brief, Huntington’s involves chorea, and tics are suppressible.
Question 6 of 9
Which statement regarding color vision is correct?
Correct Answer: B
Rationale: Color perception depends on the ratio of stimulation of red, green, and blue cones. TMP13 pp. 653-654
Question 7 of 9
Which one of the following describes saltatory conduction:
Correct Answer: D
Rationale: Saltatory conduction, where the action potential jumps between nodes of Ranvier in myelinated fibers, is faster than continuous conduction in unmyelinated fibers.
Question 8 of 9
Two primary agents of cellular communication are
Correct Answer: D
Rationale: Hormones (endocrine) and neurotransmitters (nerve-derived) are key communicators. [Level: Comprehension]
Question 9 of 9
During transmission across a typical chemical synapse,
Correct Answer: D
Rationale: An action potential causes vesicle release of neurotransmitters into the synaptic cleft, which then bind to postsynaptic receptors to transmit the signal.
