A nurse discovers that a medication error occurred during the previous shift but was not documented. The patient received double the prescribed dose of a cardiac medication and experienced mild hypotension that resolved without intervention. What is the most appropriate action for the nurse to take?

Legal and ethical standards require reporting all medication errors via incident report and chart documentation, regardless of outcome, to ensure patient safety and compliance. Other options omit necessary reporting steps.

Understanding the Priority: Accountability and System Safety
When a medication error is discovered, the primary obligations are to ensure patient safety, maintain professional accountability, and contribute to system-level prevention. The fact that the patient’s mild hypotension resolved without intervention does not negate the need for a formal report. A medication error, defined as any preventable event that may cause or lead to inappropriate medication use or patient harm, is a patient safety event that must be captured by the healthcare system. Research on patient safety event reporting emphasizes that proper documentation is crucial not for punitive reasons, but to analyze patterns and implement preventive actions to stop errors from recurring ^[1]. The immediate clinical outcome in this single case is secondary to the systemic risk the error represents.

Analyzing the Options: Why a Dual Action is Required
The nurse’s actions must align with both clinical documentation standards and risk management protocols. Let’s break down why the correct approach involves two distinct but complementary steps.

- Option 1 (Report verbally but do not document): This is incorrect and creates a dangerous gap. A verbal report alone is not a reliable part of the legal medical record. Without documentation, there is no objective, retrievable data on the event for future quality improvement reviews. Studies on healthcare professionals’ knowledge and practices regarding error reporting highlight that a lack of formal, standardized reporting is a major barrier to patient safety, particularly when systems are not standardized ^[2]. A failure to document undermines the entire purpose of having a reporting system.

- Option 2 (Document in the chart only): This is incomplete and violates standard risk management procedures. The patient’s medical chart is a clinical tool that should contain factual information about the patient’s condition—in this case, the episode of mild hypotension. However, it is not the appropriate place for a confidential analysis of the error’s root cause. An incident report (or safety event report) is a separate, confidential document used for internal quality assurance. Its purpose is to analyze the event and design preventive actions, which is a core function of a mature safety culture ^[1]. These two documentation processes serve different functions and one cannot replace the other.

- Option 3 (Complete an incident report and document per facility policy): This is the correct and most comprehensive action. It fulfills the dual ethical and professional duty. The nurse must objectively document the clinical findings in the patient’s chart (e.g., “Patient found with blood pressure 85/50 mmHg at 0800, asymptomatic. Previous shift medication record reviewed, noting a double dose of [cardiac medication] was administered at 0600. Provider notified.”). Concurrently, the nurse must complete an incident report to trigger a system-level review. This aligns with the finding that healthcare professionals’ knowledge and practices must be channeled through proper reporting structures to strengthen patient safety ^[2]. The report is about the event, not the individual, and is a critical tool for identifying latent system failures.

- Option 4 (Discuss with the previous nurse first): This is incorrect because it delays essential actions and misplaces the priority. While collegial communication is valuable for clarifying what happened, the immediate priority is patient assessment and reporting through official channels. The previous shift nurse may not be available, and any discussion does not replace the obligation to document and report through the facility’s established system. The system is designed to capture events regardless of individual conversations, ensuring a consistent and non-punitive approach to safety ^[1].

Integrating the Clinical and Systemic Rationale
The nurse’s role in this scenario is a direct application of the principles found in safety event reporting systems. The launch of an online platform for reporting patient safety events, as described in one study, was specifically designed to capture details surrounding events and the initial response to them, with the ultimate goal of creating preventive actions ^[1]. By completing an incident report, the nurse provides the raw data for this process. Simultaneously, the knowledge that medication errors are a leading cause of preventable harm globally underscores why every error, regardless of immediate patient outcome, must be formally documented and reported ^[2]. A resolved episode of mild hypotension today could be a catastrophic event tomorrow if the same system failure is allowed to persist. The nurse’s documentation in the patient’s chart provides a clear clinical picture, while the incident report provides the confidential analysis needed to correct the underlying system defect.
