Your patient has increased intracranial pressure due to a tumor, causing vasogenic edema. Which of the following drugs would you expect to be ordered to treat this specific process?

A. Corticosteroids is correct because vasogenic edema results from increased permeability of the blood-brain barrier, often associated with tumors, abscesses, or inflammation. Corticosteroids, such as dexamethasone, stabilize the blood-brain barrier, reduce capillary permeability, and help decrease edema around the tumor, thereby lowering intracranial pressure (ICP). B. Mannitol is incorrect because while it is an osmotic diuretic that reduces ICP, it is more effective for cytotoxic or general cerebral edema, not specifically for vasogenic edema caused by a tumor. Mannitol works by creating an osmotic gradient that draws fluid from the brain into the bloodstream. C. Furosemide is incorrect because it is a loop diuretic that reduces fluid volume systemically and can lower ICP indirectly, but it does not target the underlying mechanism of vasogenic edema. It is not the drug of choice for tumor-related edema. D. IV fluids is incorrect because administering IV fluids does not treat edema and may even exacerbate cerebral swelling if not carefully managed. Fluid management focuses on maintaining adequate perfusion without worsening ICP, but IV fluids are not a treatment for vasogenic edema.
