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.

Explanation
Choice A Rationale: "You sound overwhelmed, can you tell me more?" is an empathetic response that encourages the caregiver to express their feelings and concerns. It opens the door for effective communication and understanding.
Choice B Rationale: "It will take time, but lots of people do it" may be true, but it does not directly address the caregiver's emotional state or offer support.
Choice C Rationale: "What do you think will be the hardest thing to handle?" is a probing question that can help identify specific concerns, but it may not be the most appropriate initial response.
Choice D Rationale: "The entire healthcare team will manage most of the disease process" does not acknowledge the caregiver's emotions and concerns and may not provide the needed support.
Correct Answer is C
Explanation

Choice B Rationale: Removing the sequential compression device once a shift may require clarification or education but is not a significant medical concern.
Choice C Rationale: Hypoactive bowel sounds can indicate a potential bowel obstruction or paralytic ileus, which is a significant medical concern in clients with Guillain-Barre Syndrome and should be reported to the physician.
Choice D Rationale: A Glasgow Coma Score of 15 is within the normal range and would not typically require reporting to the physician in the context of Guillain-Barre Syndrome.
