A nurse manager is reviewing the rate of medication errors on a surgical floor and finds that it is 20% above the national average. After setting a standard of care, which of the following actions should the nurse manager take first using the quality improvement process?

The correct action for the nurse manager to take first is to observe staff medication administration procedures (choice C). By observing the procedures directly, the nurse manager can identify potential areas of error and understand the root causes of the high medication error rate. This step is crucial in the quality improvement process as it provides firsthand insight into the workflow and allows for targeted interventions to be developed based on actual observations.

Choice A is incorrect as collecting data related to medication errors should come after observing the procedures to ensure the data collected are relevant and reflective of the actual practices. Choice B is incorrect because re-evaluating staff performance should be based on concrete observations rather than assumptions. Choice D is incorrect as requiring staff to complete a review module may not address the specific issues leading to the high error rate.
