Patient Safety Guidelines Flashcards

A nurse administers a medication via nasogastric tube and notices that the patient's oxygen saturation drops from 98% to 91% immediately after flushing. The tube placement had been confirmed by pH testing earlier that shift. What is the most likely explanation and appropriate immediate action?

Answer: The tube has migrated into the bronchus since the last check; remove the tube immediately and notify the physician

NG tube migration into the bronchial tree can occur even after initial correct placement, particularly with patient movement, coughing, or vomiting. A sudden drop in oxygen saturation following tube flushing is a sentinel sign of pulmonary instillation. The tube must be removed immediately to stop further aspiration, and the physician must be notified. While chest X-ray is the gold standard for confirmation, immediate removal takes priority over imaging when clinical signs of aspiration are present. pH testing only confirms acidity at the time of testing and does not guarantee ongoing correct placement.

During a WHO Surgical Safety Checklist 'Time Out,' a scrub technician raises a concern that the laterality marked on the patient's left knee does not match the imaging studies, which show pathology on the right knee. The surgeon insists the mark is correct and asks the team to proceed. What is the most appropriate action according to patient safety best practice?

Answer: Halt the procedure and escalate through the chain of command until the discrepancy is resolved with supporting documentation

The WHO Surgical Safety Checklist exists precisely to catch wrong-site surgeries before irreversible harm occurs. When a team member raises a laterality discrepancy during Time Out, the procedure must be halted — this is a mandatory stop-point, not advisory. Escalation through the chain of command (charge nurse, department head, risk management) is required when the surgeon overrides a safety concern. Proceeding without resolving documented discrepancies constitutes a preventable never event. Patient safety culture mandates that any team member has the authority and obligation to halt a procedure when patient safety is at risk, regardless of hierarchy.

A patient on anticoagulation therapy is found on the floor after an unwitnessed fall. They are alert, oriented, and report no head pain. Neurological exam is intact. Which statement best reflects evidence-based patient safety management for this specific population?

Answer: Anticoagulated patients require mandatory CT head imaging after any fall, even without symptoms, due to the elevated risk of occult intracranial hemorrhage

Patients on anticoagulation (e.g., warfarin, DOACs, heparin) are at significantly elevated risk for occult intracranial hemorrhage following head trauma, even in the absence of symptoms. A lucid interval followed by rapid neurological deterioration is a recognized pattern in subdural hematoma. Current evidence-based guidelines and many institutional protocols require CT head imaging for anticoagulated patients after any fall with potential head impact, regardless of symptom status. Prophylactic reversal without imaging or indication is inappropriate and introduces its own risk of thromboembolism.

A healthcare facility is implementing a new electronic medication administration record (eMAR). During the transition week, nurses discover that the system defaults to weight-based dosing in pounds rather than kilograms for pediatric patients, opposite to the hospital's policy. Three near-miss events are reported in 48 hours. What is the primary system-level safety intervention?

Answer: Immediately suspend use of the eMAR for pediatric patients and revert to paper-based MAR until the system is corrected

Three near-miss events in 48 hours from a single system-design flaw constitutes a high-severity patient safety signal. The hierarchy of safety controls prioritizes elimination and substitution over administrative controls like training or double-checks. Relying on manual conversion introduces additional human error risk, and relying on pharmacist reconciliation as a sole backstop is insufficient for a known systematic error. Immediate suspension of the unsafe system for the affected population is the appropriate system-level response. This also triggers a mandatory rapid-cycle safety review before the system can be reactivated for pediatric use.

A patient with known penicillin allergy documented in their chart receives amoxicillin-clavulanate prescribed for a urinary tract infection. The patient has an anaphylactic reaction. During root cause analysis, it is discovered the prescribing physician saw the allergy alert but overrode it because the patient had tolerated a cephalosporin previously. Which systems-level finding is the most critical contributor to this event?

Answer: Alert fatigue from excessive low-priority override prompts diminished the weight given to a high-priority allergy warning

While knowledge gaps and individual errors contributed, root cause analysis in patient safety focuses on system-level contributors. Alert fatigue — caused by excessive, undifferentiated clinical decision support alerts — is a well-documented systemic problem that causes clinicians to routinely override alerts, including critical ones. When a system fails to stratify alerts by severity, high-priority warnings (e.g., life-threatening allergy) are mentally processed with the same weight as minor, nuisance alerts. This is a design failure of the CDSS, not primarily an individual knowledge failure. Pharmacy's role is a contributing factor but not the primary systems finding when the prescriber consciously overrode a documented allergy.

A patient is being transferred from the ICU to a step-down unit. The ICU nurse gives a verbal handoff but does not use a structured SBAR tool. The step-down nurse, new to the unit, does not receive information about a recent change in the patient's vasopressor wean status. The patient deteriorates 90 minutes after transfer. Which patient safety principle most directly applies to preventing this class of event?

Answer: Standardized handoff tools reduce information loss during care transitions by creating a shared mental model between sender and receiver

Care transitions are among the highest-risk moments for information loss and adverse events. Structured handoff tools such as SBAR (Situation, Background, Assessment, Recommendation) or I-PASS create a shared mental model that reduces omission errors by providing both sender and receiver with a predictable information architecture. The evidence base for structured handoffs in reducing adverse events is robust. While closed-loop communication (Option A) is valuable and complements structured handoffs, it is a communication technique, not the primary tool for preventing information omission at transitions. Accountability for handoff quality is shared, not solely on the sender, making Option C incorrect.
