Review of Systems Neurological Questions Questions
Question 1 of 5
As the action potential swings down,
Correct Answer: A
Rationale: During the repolarization phase of an action potential, potassium ions move out of the axon, restoring the negative charge inside the neuron. This efflux of potassium ions helps return the membrane potential to its resting state after depolarization. The movement of potassium ions is facilitated by voltage-gated potassium channels, which open in response to the change in membrane potential.

Question 4 of 5
While obtaining a patient's medical history, you find that the patient is taking levodopa/carbidopa (Sinemet) for Parkinson's disease. Which of the following information in the patient's health history alerts you to take further action?
Correct Answer: C
Rationale: The combination of levodopa and carbidopa, both dopamine-replacement drugs, can cause changes in intraocular pressure. Providers should not prescribe this drug combination for patients who have glaucoma, and in this case, the patient's drug therapy requires adjustment. Pancreatic disorders are not a contraindication for levodopa/carbidopa; instead, caution is required when using it with patients who have peptic ulcer disease. Hearing impairment is not a contraindication for levodopa/carbidopa; instead, it can cause a variety of vision disturbances.

A 26 year-old man was in a motor vehicle accident and suffered a complete spinal cord injury to L3. The nurse assesses the patient for loss of motor function in the:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
