Sample questions from this domain
These are real, source-cited questions from our bank. For a scored, timed run, take the Patient Safety Quiz.
1. Which statement correctly defines a high-alert medication?
- A. A drug that is involved in errors more often than any other medication
- B. A drug that must always be stored in a locked safe with a perpetual inventory
- C. A drug that requires REMS program enrollment before dispensing
- D. A drug that bears a heightened risk of causing significant patient harm when it is used in error ✓
Answer: D. ISMP defines high-alert medications as drugs that bear a heightened risk of causing significant patient harm when used in error. Mistakes with these drugs are not necessarily more common, but the consequences of an error are clearly more devastating. That is why they warrant special safeguards.
2. Which class of drugs appears on the ISMP List of High-Alert Medications in Acute Care Settings?
- A. Neuromuscular blocking agents such as succinylcholine, rocuronium, and vecuronium ✓
- B. Proton pump inhibitors such as omeprazole
- C. HMG-CoA reductase inhibitors such as atorvastatin
- D. Topical antifungals such as clotrimazole
Answer: A. Neuromuscular blocking agents are on the acute care high-alert list because accidental administration to a patient who is not mechanically ventilated causes paralysis and death. The list also includes classes such as insulin, opioids, antithrombotics, and concentrated electrolytes. PPIs, statins, and topical antifungals are not high-alert classes.
3. Which specific medication did ISMP add to its List of High-Alert Medications in Acute Care Settings in the 2024 update?
- A. Naloxone injection
- B. Tolvaptan
- C. Tranexamic acid injection ✓
- D. Alprostadil
Answer: C. ISMP added tranexamic acid injection to the specific medications section of the 2024 acute care list. Vials are often confused with look-alike anesthetic vials stored in surgical areas, and accidental neuraxial injection is a potent neurotoxin with roughly 50 percent mortality. Naloxone, tolvaptan, and alprostadil were suggested by survey respondents but were not added.
