A client who recently received a prescription for ramelteon to treat sleep deprivation reports experiencing several side effects since taking the drug. Which side effect should the nurse report to the healthcare provider?

A. Mild sedation is a common side effect of ramelteon and typically does not require immediate medical attention. It may improve with continued use as the body adjusts to the medication. B. Somnambulism (sleepwalking) is a less common but potentially serious side effect of ramelteon. It can pose safety risks to the client, and the healthcare provider should be notified promptly to assess the severity and determine if the medication needs to be adjusted or discontinued. C. A change in the sleep-wake cycle is a common intended effect of ramelteon as it helps regulate sleep patterns. However, if the change is extreme or disruptive, it may warrant further evaluation by the healthcare provider. D. Dizziness reported after the initial dose is a common side effect of ramelteon and usually diminishes with continued use. It may not require immediate medical attention unless it persists or worsens.
