Final answer:
After an ischemic stroke, nursing care during immediate recovery should include positioning to avoid hypoxia, which helps minimize brain swelling and reduce further injury. Administering hypertonic IV solutions may be done under medical guidance to control edema. Early mobilization is also crucial but only when the patient is stable.
Step-by-step explanation:
After a major ischemic stroke, a possible complication is cerebral edema. During the immediate recovery period, nursing care should include positioning to avoid hypoxia. This is because proper positioning can help minimize brain swelling and reduce the potential for further injury. Maximizing PaCO2 is not advised as elevated CO2 levels can lead to cerebral vasodilation and potentially increase intracranial pressure. While administering hypertonic IV solutions may help to control edema, it must be done carefully under strict medical guidance to manage the osmotic gradient and avoid rapid shifts in fluids that could worsen outcomes. Initiating early mobilization depends on the stability of the patient and the extent of neurological impairment; it is important, but not in the 'immediate' post-stroke period where the focus is on stabilizing the patient and managing life-threatening complications.
