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 A
Explanation
Choice A Rationale: some medications that are used to calm down people with dementia can have serious side effects, especially for older adults. One of these side effects is an increased risk of experiencing a stroke, which can be life-threatening.
Choice B Rationale: Increased blood pressure can be a side effect of some medications used to calm patients with dementia, but it may not be the primary reason for not prescribing such medications. Furthermore, some medications can lower blood pressure, not increase it.
Choice C Rationale: Increased risk for infection is not typically a reason to avoid medications to calm dementia patients.
Choice D Rationale: is partially true because some medications can increase the risk for falls, but this is not the main reason why they are avoided.
Correct Answer is A
Explanation
Choice A Rationale: Sitting the client at a 90-degree angle (upright position) helps prevent orthostatic hypotension and cardiovascular complications in clients with spinal cord injuries by improving venous return and cardiac output.
Choice B Rationale: Administering 2000 liters of fluid is an inappropriate intervention, and the volume mentioned is excessive.
Choice C Rationale: Applying compression socks may help prevent deep vein thrombosis (DVT) but does not address cardiovascular complications related to sitting position.
Choice D Rationale: Maintaining blood pressure exactly at 110/80 is not a feasible or appropriate intervention.
