Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
Bitemporal hemianopia is caused by:
Correct Answer: C
Rationale: Bitemporal hemianopia results from optic chiasm compression, commonly by pituitary tumors (C). Optic nerve lesions (A) cause unilateral loss, optic tract (B) causes homonymous hemianopia, and occipital lesions (D) affect cortical vision. C is correct.
Question 2 of 5
The following is true about the vestibular system:
Correct Answer: D
Rationale: Vestibular system affects balance, not muscle tone directly (A). Semicircular canals detect angular acceleration (not linear, B), utricle detects linear (not rotational, C). Damage causes vertigo (D, correct). D is true.
Question 3 of 5
Which structure is associated with the embryologic development of the peripheral nervous system?
Correct Answer: A
Rationale: The neural crest (A) gives rise to the peripheral nervous system (PNS), including sensory and autonomic ganglia. The neuraxis (B) is the central nervous system (CNS) axis, rhombencephalon (C) forms brainstem and cerebellum (CNS), and neural tube (D) forms the CNS. A is correct.
Question 4 of 5
Which layer of the meninges surrounds and supports the sinuses that form the route through which blood drains from the CNS?
Correct Answer: A
Rationale: The dura mater (A) forms and supports venous sinuses (e.g., superior sagittal) for CNS blood drainage. The arachnoid mater (B) and subarachnoid space (C) handle CSF, and pia mater (D) adheres to the brain. A is correct.
Question 5 of 5
Which of these structures is not under direct control of the peripheral nervous system?
Correct Answer: A
Rationale: The peripheral nervous system (PNS) controls peripheral structures. The trigeminal ganglion (A) is a sensory relay, not directly controlled by PNS motor output. Gastric plexus (B), sympathetic chain (C), and cervical plexus (D) are PNS autonomic/somatic effectors. A is the least directly controlled.
