A nurse observes a colleague who appears to be under the influence of alcohol during a night shift. The colleague's speech is slurred, there is a strong odor of alcohol, and the colleague has made two medication errors in the past hour. What is the nurse's most appropriate immediate action?

Patient safety is the highest priority when a colleague shows signs of impairment (slurred speech, alcohol odor, medication errors). Immediate notification to the charge nurse/supervisor ensures removal from patient care and activation of protocols. Other options delay action and risk patient harm.

Correct Answer: 4. Immediately notify the charge nurse or nursing supervisor and remove the colleague from patient care

Analysis of the Clinical Scenario
This question addresses the critical nursing responsibility of ensuring patient safety when a colleague is impaired. The scenario presents clear, objective signs of impairment: slurred speech, a strong odor of alcohol, and, most critically, two medication errors in the past hour. This combination of physical signs and direct evidence of patient harm elevates the situation from a suspicion to an immediate safety emergency.

Why Immediate Removal and Reporting is the Only Correct Action
The nurse practice act and professional standards in every jurisdiction mandate that a nurse's primary duty is to protect the public. When a colleague's impairment creates an imminent threat to patient safety, the obligation is not to counsel, diagnose, or monitor the colleague, but to act decisively to safeguard patients. The presence of medication administration errors is the definitive factor here. This is not a vague suspicion; it is an active, ongoing patient safety crisis.

The systematic review by Zhao et al. (2026) provides a powerful, evidence-based context for this urgency ^[1]. Their work highlights that medication administration errors are a major cause of adverse events, and that even when safety systems like double-checking are in place, adherence is inconsistent and often omitted when clinical demands compete. In this scenario, the impaired colleague is not simply failing to follow a policy; their compromised cognitive and motor function has already defeated the safety net, resulting in actual errors. The review's finding that nurses' adherence to safety procedures is vulnerable to competing demands underscores why a colleague's impairment is so dangerous—it represents a complete breakdown of the individual's ability to function within the safety system. Removing the colleague from patient care is the only way to immediately halt the cascade of potential harm that the systematic review identifies as a major cause of adverse events ^[1].

Critique of the Incorrect Options

- Option 1: Documenting and reporting at the end of the shift. This is a dangerously passive approach. The systematic review's findings on medication errors make it clear that every moment the impaired nurse remains in a patient care role carries a high risk of a new, preventable adverse event ^[1]. Delaying intervention for hours is a failure to protect patients from an immediate threat.

- Option 2: Confronting the colleague directly. While direct communication is often valued in nursing, it is inappropriate in this context. A nurse under the influence may become defensive, agitated, or deny the situation, leading to a confrontation that delays the essential step of securing patient safety. The nurse's role is not to investigate or extract a confession, but to report the objective observations to a supervisor who has the authority to manage the personnel issue.

- Option 3: Continuing to monitor the colleague. This option fails to recognize that the threshold for action has already been crossed. The documentation of two medication errors is not a baseline for further observation; it is the sentinel event that demands immediate termination of the colleague's patient care duties. Continued monitoring implies a tolerance of the ongoing risk, which is ethically and legally indefensible.

Clinical and Regulatory Reasoning
The most appropriate immediate action is a two-part process: (1) ensure the colleague is removed from any direct patient care responsibilities, and (2) immediately notify the charge nurse or nursing supervisor. This sequence prioritizes patient safety above all else. The supervisor then assumes the responsibility for further investigation, securing safe transport for the colleague, and managing the legal and employment implications. The nurse's documentation of the objective observations (slurred speech, alcohol odor, specific medication errors) should occur as soon as possible after the immediate safety actions are taken, creating a clear, factual record of the events that triggered the intervention. This approach directly addresses the core problem identified in the literature: that systems and individual vigilance are both required to prevent the medication errors that cause patient harm ^[1].
