A 17-year old was injured after diving into shallow water. He was transported to the emergency department where imaging indicated he suffered a spinal cord injury. Based on this information, what mechanism likely caused the spinal cord injury?
hyperextension
compression
flexion-rotation
flexion
The Correct Answer is B
Choice A Rationale: hyperextension is when the neck is bent backward beyond its normal range of motion. This can happen in a rear-end collision or a fall on the back of the head.
Choice B Rationale: A spinal cord injury occurs when there is damage to the spinal cord or the surrounding structures, such as the vertebrae, ligaments, or discs. The most common cause of spinal cord injury is trauma, which can result from direct impact, penetration, or excessive force on the spine. Diving into shallow water can cause compression of the spine, which means that the vertebrae are pushed together and squeeze the spinal cord. This can damage the nerve fibers and disrupt the communication between the brain and the body. Compression injuries can affect any part of the spine, but are more common in the cervical and thoracic regions.
Choice C Rationale: flexion-rotation is when the neck is bent and twisted at the same time. This can happen in a sports injury or a violent assault.
Choice D Rationale: This is when the neck is bent forward beyond its normal range of motion. This can cause the posterior part of the vertebral column to compress and fracture, while the anterior part of the spinal cord is stretched and injured. This can happen in a head-on collision or a fall on the face. A flexion-rotation is when the neck is bent and twisted at the same time.

Correct Answer is D
Explanation
Choice A Rationale: Guillain-Barre syndrome does not typically cause enlargement of parotid and salivary glands, leading to drooling.
Choice B Rationale: Obstructed blood flow to the brain is not the primary cause of the described symptoms in Guillain-Barre syndrome.
Choice C Rationale: Deficiency of thiamine and pyridoxine in the central nervous system is not a characteristic feature of Guillain-Barre syndrome.
Choice D Rationale: In Guillain-Barre syndrome, demyelination affects cranial nerves responsible for swallowing and the gag reflex, leading to difficulties in swallowing secretions and drooling.
Correct Answer is ["A","B","D"]
Explanation
Choice A Rationale: A weakened gag reflex is a potential complication of a cervical spinal cord injury and can lead to difficulties in swallowing and increased risk of aspiration.
Choice B Rationale: Hyperthermia can occur as a result of autonomic dysfunction associated with spinal cord injuries, especially when the injury is at a high cervical level.
Choice C Rationale: Absence of bowel sounds is not typically associated with cervical spinal cord injuries but may be seen in lower spinal cord injuries.
Choice D Rationale: Hypotension is a potential complication due to impaired autonomic regulation in cervical spinal cord injuries.
Choice E Rationale: Polyuria is not typically associated with cervical spinal cord injuries but may occur in cases of lower spinal cord injuries affecting bladder function.
