Health Assessment Neurological System NCLEX Questions Questions
Question 1 of 5
Gaps in the myelin sheath are called _______.
Correct Answer: A
Rationale: Nodes of Ranvier are small gaps in the myelin sheath along the axon of a neuron. These gaps allow for the rapid conduction of nerve impulses through a process called saltatory conduction, where the action potential 'jumps' from one node to the next. This increases the speed and efficiency of neural communication. Nodes of Ranvier are essential for proper nerve function and are found in both the peripheral and central nervous systems.
Question 2 of 5
The part of the brain responsible for coordinating all your movements is the:
Correct Answer: B
Rationale: The cerebellum is responsible for coordinating voluntary movements, balance, and posture. It receives sensory input from the spinal cord and other parts of the brain to fine-tune motor activities. The cerebellum ensures smooth and precise movements by integrating information about body position and muscle activity. Damage to the cerebellum can result in uncoordinated movements, balance issues, and difficulties with fine motor skills.
Question 3 of 5
Collections of nerve cell bodies inside the PNS are called:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Sally has a brain injury; she knows what she wants to say but can't vocalize the words. The part of her brain that deals with the ability to speak is the:

Question 5 of 5
You are caring for a patient who is preoperative and is NPO. The patient takes carbamazepine (Tegretol), 200 mg PO BID for a seizure disorder. Which of the following actions should you take?
Correct Answer: A
Rationale: It is important to continue the oral carbamazepine to maintain therapeutic blood levels and to prevent seizure activity. You should notify the anesthesiologist and should give the patient the carbamazepine with a sip of water. Carbamazepine is not available IV. Withholding the carbamazepine may reduce the therapeutic blood level and cause seizure activity. Administering a reduced dose of carbamazepine may reduce the therapeutic blood level and cause seizure activity.
