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

4. ISMP recommends that concentrated potassium chloride (KCl) for injection should:

  • 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
