The nurse is caring for a patient who has a spinal cord injury at the level of C-6. The patient displays the following symptoms: loss of motor function on the ipsilateral side of the injury, loss of temperature and pain sensation on the contralateral side. What type of injury did this individual most likely suffer?
Posterior cord injury
Anterior cord injury
Central cord injury
Brown-Sequard injury
The Correct Answer is D
A. Posterior cord injury usually affects proprioception rather than causing a distinctive pattern of motor and sensory loss.
B. Anterior cord injury generally impacts motor function and temperature and pain sensation bilaterally, not in a hemisection pattern.
C. Central cord injury primarily affects motor function in the upper extremities and is not characterized by ipsilateral motor and contralateral sensory loss.
D. Brown-Sequard syndrome typically presents with motor function loss on the same (ipsilateral) side of the injury and loss of pain and temperature sensation on the opposite (contralateral) side, making this the most likely diagnosis.

Correct Answer is C
Explanation
A. While anxiety can cause gastrointestinal symptoms, the context of this patient’s experience with seizures indicates that it is specifically related to the seizure disorder rather than an independent anxiety issue.
B. The sensation of "butterflies" is not typically related to hunger, as hunger is more commonly associated with physical feelings of emptiness or pain rather than a specific butterfly sensation.
C. An aura is a perceptual disturbance experienced by some patients with seizure disorders that precedes a seizure. It can manifest as various sensations, including gastrointestinal feelings like "butterflies," which serve as a warning sign that a seizure is imminent.
D. A postictal sign refers to the state of confusion or altered consciousness following a seizure, rather than sensations experienced prior to the seizure.
Correct Answer is C
Explanation
A. While lung injury could occur in traumatic situations, it is not the primary reason for mechanical ventilation in the context of a spinal cord injury.
B. A history of smoking may affect lung health but does not directly justify the immediate need for mechanical ventilation following a spinal cord injury.
C. The nerves that control lung function may be injured in a cervical spinal cord injury, particularly at higher levels like C3-C5, leading to respiratory muscle paralysis and necessitating mechanical ventilation to support breathing.
D. While unconsciousness may complicate breathing, the primary concern is the loss of function in the spinal cord nerves controlling respiration.
