Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
One of the 31 pairs of nerves that originate on the spinal cord from posterior and anterior roots.
Correct Answer: B
Rationale: Spinal nerves are 31 pairs formed by anterior (motor) and posterior (sensory) roots exiting the spinal cord. Action potentials are signals, Guillain-Barré is a disorder, and nervous system is too broad.
Question 2 of 5
Any stress that changes a controlled condition; any change in the internal or external environment that excites a sensory receptor, a neuron, or a muscle fiber.
Correct Answer: D
Rationale: A stimulus is any change (e.g., light, pressure) that activates sensory receptors, neurons, or muscles. Enteric plexuses are digestive nerves, axoplasm is axon cytoplasm, and synaptic cleft is a synapse gap.
Question 3 of 5
An extension of a neuron that conducts a nerve impulse toward a synapse; may be myelinated or unmyelinated.
Correct Answer: A
Rationale: A nerve fiber (axon) conducts impulses toward a synapse. Myelin sheath insulates, axon is a synonym, and effectors are targets.
Question 4 of 5
A malignant tumor that consists of immature nerve cells (neuroblasts); occurs most commonly in the abdomen and most frequently in the suprarenal glands.
Correct Answer: B
Rationale: Neuroblastoma is a malignant tumor of immature neuroblasts, common in children’s adrenal glands. Axoplasm is axon cytoplasm, action potential is a signal, and axosomatic is a synapse.
Question 5 of 5
Movement in which a part of the body moves inferiorly.
Correct Answer: D
Rationale: Depression is the anatomical movement of a body part downward (e.g., shoulder). Action potential is a signal, astrocytes are glia, and interneurons are neurons.
