Q2 An older adult patient is brought by their spouse to the Family Practice Clinic with an inability to speak normally. The patient is then transferred to the hospital due to a suspected stroke. The nurse practitioner, while explaining to an NP student, discusses that the presentation is most likely indicative of an ischemic stroke. Why does the NP emphasize that ischemia, as opposed to hypoxia, is often more severe in terms of its impact on brain function and patient outcomes?
Group of answer choices
Ischemic brain injury is typically reversible with prompt medical intervention, while hypoxic brain injury often results in irreversible damage.
Ischemia does not result in the accumulation of toxic metabolites, unlike hypoxia.
Ischemic brain injury involves both reduced oxygen and nutrient supply, causing more severe tissue damage.
Hypoxic brain injury often leads to more inflammation than ischemic brain injury, contributing to worse outcomes.
