What is the first step a nurse should take when a medication error is identified?

The first step a nurse should take when a medication error is identified is to assess the patient. This action is critical because the patient's safety and well-being are the top priorities. By assessing the patient, the nurse can determine if there are any immediate adverse effects or complications resulting from the medication error. This assessment can include vital signs monitoring, evaluating the patient's current condition, and noting any symptoms that may have arisen due to the error.

Taking prompt action in assessing the patient allows for timely interventions, which can mitigate harm. It is essential to establish how the error has affected the patient, whether through direct side effects of the wrong medication, the impact of an omitted dose, or any potential harmful interactions. This assessment forms the foundation for further actions, such as notifying healthcare providers, providing treatment if necessary, and implementing an appropriate response plan.

Following this initial patient assessment, other actions like notifying the patient, informing the pharmacy, and documenting the error can be taken. However, the immediate focus should always be on the patient's condition to ensure their safety and provide necessary care.
