ANS: A
Drug actions and interactions are common among elderly persons and predispose this population to delirium. Delirium is characterized by an abrupt onset of fluctuating levels of awareness, clouded consciousness, perceptual disturbances, and disturbed memory and orientation. The patient takes lorazepam on a PRN basis, so withdrawal is unlikely. Hypotensive episodes or problems with renal function may occur associated with the patient's drug regime, but interactions are more likely the problem.
