Two days following a spinal cord injury, a patient asks continually about the extent of impairment that will result from the injury. What is the best response by the nurse?
- A. You will have more normal function when spinal shock resolves and the reflex arc returns.'
- B. The extent of your injury cannot be determined until the secondary injury to the cord is resolved.'
- C. When your condition is more stable, MRI will be done to reveal the extent of the cord damage.'
- D. Because long-term rehabilitation can affect the return of function, it will be years before we can tell what the complete effect will be.'
Correct Answer: B
Rationale: Secondary injury resolution is necessary to assess the full extent of the injury.

With an action potential, depolarization of the axomembrane is recorded as the gates open, allowing ________ to flow into the axon.
- A. potassium ions
- B. H+ ions
- C. sodium ions
- D. all of the above
Correct Answer: C
Rationale: During the depolarization phase of an action potential, voltage-gated sodium channels open, allowing sodium ions to flow into the axon. This influx of positively charged ions causes the membrane potential to become more positive, leading to the rapid rise in voltage observed during an action potential. Sodium ion influx is essential for initiating and propagating nerve impulses.
In the context of brain imaging, what does FMRI stand for?
- A. fast moving recovery imaging
- B. first moveable recording indicator
- C. flexible motion resistance indicator
- D. functional magnetic resonance imaging
Correct Answer: D
Rationale: Functional Magnetic Resonance Imaging (fMRI) is a brain imaging technique that measures brain activity by detecting changes in blood flow. When a brain region is active, it consumes more oxygen, and fMRI captures this increased blood flow. This non-invasive method is widely used in neuroscience to study brain function and map neural activity during various tasks. fMRI has revolutionized our understanding of the brain's organization and function.
During the patient's process of grieving for the losses resulting from spinal cord injury, what should the nurse do?
- A. Help the patient to understand that working through the grief will be a lifelong process
- B. Assist the patient to move through all stages of the mourning process to acceptance
- C. Let the patient know that anger directed at the staff or the family is not a positive coping mechanism
- D. Facilitate the grieving process so that it is completed by the time the patient is discharged from rehabilitation
Correct Answer: A
Rationale: Grieving is a long-term process requiring ongoing support.
Cell bodies for the motor supply of the facial nerve lie
- A. Hypothalamus
- B. Midbrain
- C. Floor of the third ventricle
- D. Pons
Correct Answer: D
Rationale: The motor nucleus of the facial nerve is located in the pons. It controls muscles of facial expression, such as the orbicularis oculi and buccinator.
Which of the following is not a side effect of dopamine agonists?
- A. Drowsiness
- B. Nausea
- C. Impulse control disorder
- D. Livedo reticularis
Correct Answer: D
Rationale: Livedo reticularis is not a side effect of dopamine agonists. Common side effects include drowsiness, nausea, and impulse control disorders.
