Why High-Alert Medications & Error Prevention matters
High-Alert Medications & Error Prevention is one of the most tested areas because medication errors are among the most preventable causes of patient harm.
Sample Practice Questions (5)
1. A "root cause analysis" (RCA) in pharmacy error investigation:
- Identifies the underlying system failures that contributed to the error, not just the individual who made it
- Determines which employee to terminate
- Calculates the financial cost of the error
- Is performed only for errors reported to the FDA
2. The ISMP recommends that which high-alert medication class should have automatic dose limits ("hard stops") programmed into infusion pumps?
- Opioids and anticoagulants (heparin)
- Antacids and stool softeners
- Multivitamins and iron supplements
- Antihistamines and cough suppressants
3. Confusion between vinCRIStine (IV only) and vinBLAStine has led to fatal errors. ISMP recommends that vincristine be:
- Dispensed in a minibag (NOT a syringe) and labeled "FOR IV USE ONLY — FATAL IF GIVEN INTRATHECALLY"
- Stored at room temperature to differentiate from vinblastine
- Given only in oral form to prevent IV errors
- Colored red to distinguish it from vinblastine

- NOT be available as floor stock in patient care areas — it should only be available as premixed solutions
- Be stored alongside normal saline for convenience
- Be available in all patient care areas in concentrated vials
- Be administered by IV push for rapid correction
5. An "independent double-check" in pharmacy means:
- A second person independently verifies the drug, dose, and patient without being told the expected answer
- The same technician checks their own work twice
- The patient checks the label before leaving
- The software automatically checks for errors
