During her assessment, a nurse identifies that an older adult client with mild neurocognitive disorder is showing symptoms of delirium after being given sleeping pills. What should be the immediate action?

A. Monitoring vital signs and cognitive status is important, but it is not sufficient as an immediate response when delirium is suspected to be medication-induced. Waiting without intervention could worsen the client’s condition. B. Administering more sleeping pills would exacerbate delirium and increase the risk of adverse effects such as sedation, falls, respiratory depression, or further cognitive decline. This action is unsafe. C. Encouraging increased fluid intake may help overall health but does not address the acute cause of delirium. It is insufficient as an immediate intervention. D. Discontinuing the sleeping pills and consulting the healthcare provider is the safest and most appropriate immediate action. Older adults with neurocognitive disorders are particularly sensitive to sedative-hypnotic medications, and these drugs are a common precipitating factor for delirium. Stopping the causative medication and seeking medical guidance allows for rapid assessment, prevention of complications, and adjustment of the treatment plan.
