What clinical finding is associated with hydralazine toxicity?

A. Seizure: Seizures are not a common manifestation of hydralazine toxicity. While severe hypotension could contribute to CNS symptoms, seizures are not a typical or expected clinical finding with this medication. B. Hypertension: Hydralazine is a direct vasodilator used to lower blood pressure. Hypertension is not associated with hydralazine toxicity; instead, excessive hypotension may occur if the drug effect is too strong. C. Tachycardia: Tachycardia is a common clinical finding associated with hydralazine toxicity. The vasodilation caused by hydralazine can lead to reflex sympathetic stimulation, resulting in an increased heart rate as the body attempts to maintain cardiac output and blood pressure. D. Constipation: Constipation is not related to hydralazine use or toxicity. This adverse effect is not expected and does not indicate toxicity from the medication.
