A nurse is caring for a client who has a traumatic brain injury and is being mechanically ventilated. Which of the following can cause unfavorable outcomes for this client?
Hyperoxia
Platelet count 250,000/mm^3
Hemoglobin 16 g/dL
Glasgow Coma Scale 16
The Correct Answer is A
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.

Correct Answer is A
Explanation
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.
Correct Answer is C
Explanation
Choice A rationale
Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. It does not cause a sensation of tightness around the torso.
Choice B rationale
Lhermitte’s sign is a symptom of multiple sclerosis and other neurological conditions where a person feels an electric shock-like sensation running down the spine and into the limbs. It does not cause a sensation of tightness around the torso.
Choice C rationale
The sensation of tightness around the torso in a patient with multiple sclerosis is often referred to as the “MS hug”. It is caused by a lesion or an area of active inflammation within the spinal cord.
Choice D rationale
Paroxysmal spasms are a type of muscle spasm experienced by some people with multiple sclerosis. These spasms are usually painful and involve the muscles of the legs, but they do not cause a sensation of tightness around the torso.
