What condition should a patient receiving nitroprusside for hypertensive emergency be assessed for?

When a patient is administered nitroprusside for a hypertensive emergency, the primary concern is the potential for significant drops in blood pressure, leading to a hypotensive crisis. Nitroprusside is a potent vasodilator that rapidly lowers blood pressure, so careful monitoring is essential. If the drug's effects are not appropriately managed, it can lead to excessive hypotension, which may result in inadequate perfusion to vital organs and could have serious consequences such as organ failure or shock. Consequently, assessing the patient for signs of hypotension is crucial in ensuring the safe use of nitroprusside.
