About this test
Patient Safety and Quality Assurance is Domain 3 of the PTCE and the second-largest at 23.75% of the 2026 exam. It's also the domain most directly tied to your day-one duties: preventing the errors that hurt patients.
This quiz covers high-alert and look-alike/sound-alike (LASA) medications, error-prevention strategies like Tall Man lettering and barcode scanning, the situations that require pharmacist intervention (DUR alerts, OTC recommendations, suspected misuse), event-reporting systems including MedWatch and VAERS, common prescription error types, and infection-prevention procedures.

Key concepts to know
When a technician must escalate
Any drug utilization review alert, therapeutic substitution question, OTC recommendation, suspected adverse drug event, immunization follow-up concern, or patient question about drug selection must go to the pharmacist. The exam loves scenarios that test whether you know where the technician's scope ends.
LASA and Tall Man lettering
Pairs like hydrOXYzine/hydrALAZINE, predniSONE/prednisoLONE and NIFEdipine/niCARdipine are separated on shelves and distinguished with Tall Man capitals. Know the strategy and the classic pairs.
Reporting systems
MedWatch is the FDA's program for adverse events and product problems; VAERS handles vaccine adverse events; ISMP runs voluntary error-reporting programs. Root-cause analysis and CQI processes turn individual reports into system fixes.
