A nurse is caring for a patient who was involved in a motor vehicle accident.The patient is alert and oriented and reports a loss of consciousness immediately after the accident.
Which of the following additional symptoms should the nurse assess the patient for? (Select All that Apply.)

Choice A rationale
A traumatic brain injury (TBI) can indeed disrupt cellular function and cause blood vessel damage. This can lead to a range of potential effects, from temporary changes in brain function to long-term complications or even death.
Choice B rationale
Damage to brain tissue from decreased pressure shock waves is not typically associated with TBI. This type of injury is more commonly associated with blast injuries, such as those caused by explosions.
Choice C rationale
While increased blood supply and edema (swelling) can occur in the area of a brain injury, they are typically responses to the injury rather than direct consequences of the TBI itself. These processes can contribute to further damage and complications.
Choice D rationale
A TBI does not typically lead to increased synaptic connections. In fact, the injury can cause loss of neurons and synapses, which can lead to long-term cognitive and functional impairments.

Choice A rationale

Hyperoxia, or high oxygen levels, can cause unfavorable outcomes for a client who has a traumatic brain injury and is being mechanically ventilated. Too much oxygen can lead to oxygen toxicity and cause damage to the lungs and other organs, including the brain.
Choice B rationale
A platelet count of 250,000/mm^3 is within the normal range and would not typically cause unfavorable outcomes for a client who has a traumatic brain injury and is being mechanically ventilated.
Choice C rationale
A hemoglobin level of 16 g/dL is within the normal range and would not typically cause unfavorable outcomes for a client who has a traumatic brain injury and is being mechanically ventilated.
Choice D rationale
A Glasgow Coma Scale score of 16 is not possible as the maximum score is 15. A higher score indicates a less severe injury, so it would not typically cause unfavorable outcomes for a client who has a traumatic brain injury and is being mechanically ventilated.
