Learn classes before drugs — one suffix unlocks ten names — then attach indications and warnings to the class, not the molecule.Suffixes → classes: the highest-yield table in the domainInteraction families the exam actually tests (1.2, 1.3)Scenario questions cluster around a handful of mechanisms: two drugs that both thin blood (anticoagulant + NSAID), two that both depress breathing (opioid + benzodiazepine), two that both raise serotonin, duplicated therapy inside one class (two NSAIDs — the classic 1.2 item), and grapefruit or azole antifungals boosting a statin. When a stem lists two drugs, ask “what do these have in common?” — the overlap IS the answer.Storage, stability, and the cold chain (1.4, 1.7, 1.8)Stability (1.7) is NEW emphasis on the 2026 outline: reconstituted suspensions carry short beyond-use dates, insulin in use follows the label’s day count, and anything past its BUD is a non-dispensable return — storage ranges above follow USP packaging-and-storage conventions; the label always wins.… ### Federal Requirements (18.75% of the exam) Knowledge areas: 2.1 Hazardous handling & disposal; 2.2 Controlled prescriptions & DEA schedules; 2.3 Controlled-substance operations; 2.4 Restricted drug programs; 2.5 FDA recalls; 2.6 DSCSA track & trace Practice: https://ptcbready.com/quiz/federal-law The smallest domain, and the most memorizable: hazardous handling (2.1), controlled substances end to end (2.2, 2.3), restricted programs (2.4), recalls (2.5), and the supply chain (2.6). Every fact below was checked against the current CFR or FDA text.DEA schedules (2.2)DEA forms (2.3)Recall classes (2.5)The legislation timelineDSCSA (2.6) is the 2026outline’s headline addition: package-level product identifiers, transaction data between authorized trading partners, and quarantine-then-investigate for suspect product. Most prep sites still don’t cover it; the quiz bank here has a full DSCSA area.… ### Patient Safety & Quality Assurance (23.75% of the exam) Knowledge areas: 3.1 High-alert & look-alike drugs; 3.2 Error-prevention strategies; 3.3 Pharmacist-intervention triggers; 3.4 Event reporting; 3.5 Prescription-error types; 3.6 Infection prevention Practice: https://ptcbready.com/quiz/patient-safety The second-largest domain tests systems, not trivia: which drugs deserve extra process (3.1), how errors are prevented structurally (3.2), when the pharmacist must step in (3.3), where events get reported (3.4), how errors are classified (3.5), and hygiene standards (3.6).High-alert classes (3.1)LASA pairs with Tall Man lettering (3.1, 3.2)Prevention mechanics the exam names (3.2, 3.5)Who gets the report (3.4)Pharmacist-intervention triggers (3.3): DUR alerts, adverse-event reports, OTC recommendations, therapeutic substitution, suspected misuse, adherence problems, post-immunization reactions, and any new allergy or interaction flag. The tech’s job is recognizing the trigger and routing it — never resolving it. Infection prevention (3.6) is process hygiene: hand-washing between patients, PPE for compounding, and cleaning counting trays (notably after penicillins) and counters on schedule.… ### Order Entry & Processing (22.5% of the exam) Knowledge areas: 4.1 Calculations & sig codes; 4.2 Administration equipment & supplies; 4.3 NDC, lot & expiration; 4.4 Returns & non-dispensable stock Practice: https://ptcbready.com/quiz/order-entry Where the math lives (4.1 — drilled in the calculations chapter below), plus the physical goods: administration supplies (4.2), package identity (4.3), and what may go back on the shelf (4.4).Sig codes — the high-yield dozen (4.1)NDC structure (4.3)FDA assigns a 10-digit NDC in 4-4-2, 5-3-2, or 5-4-1; billing systems pad a zero to a standardized 11-digit 5-4-2.DAW codes (4.1)Returns (4.4): sealed, in-date stock that never left the pharmacy may return to shelf; anything dispensed to a patient, expired, or recalled routes to reverse distribution or quarantine — never back to stock. Lot number + expiration travel with every return decision (4.3), which is why the exam pairs those two areas.… ### Calculations — the cluster that decides pass/fail Knowledge areas: 1.4 Doses, forms & routes; 4.1 Calculations & sig codes; 4.2 Administration equipment & supplies Practice: https://ptcbready.com/pharmacy-tech-math Calculation items concentrate in areas 1.4, 4.1, and 4.2 and behave differently from recall: they’re slow, they chain, and they punish setup errors. These two worked examples come straight from the engine that generates the trainer’s infinite stream — every number recomputes, every step lands on the answer.The conversions to burn inThe full chart (with worked trap rows and the printable) lives on the conversions page; the must-memorize set is marked row by row.
