What action should a nurse prioritize for a client experiencing an acute episode of vertigo?

In the context of a client experiencing an acute episode of vertigo, prioritizing the action of raising the upper side rails of the client's bed serves a critical purpose in ensuring the client's safety. Vertigo can lead to dizziness and a sensation of spinning, increasing the risk of falls and potential injury. By raising the side rails, the nurse is providing an immediate measure to prevent the client from accidentally falling out of bed, thereby enhancing safety during this disorienting time.

While assessing for nausea and vomiting is important, and instructing the client to avoid sudden movements can also help reduce symptoms, ensuring that the client remains safe in bed takes precedence during an acute episode. Requesting medication might be necessary for long-term management, but safe containment during an active episode is the top priority. Therefore, enhancing safety through physical measures, such as raising bed rails, is considered the most urgent nursing action in this situation.
