9.2 Last-Week Review Map

9.2 Last-Week Review Map

The final week is for consolidation, calm, and confirming the exact numbers the CER exam loves to test. Build your map from the official HSPA content outline, your error log, and your timed-set scores — not from new books. The CER blueprint weights the reprocessing workflow heavily, so allocate review time by impact.

A 7-day plan keyed to CER weight

The numbers distractors exploit

Most wrong CER answers attack a precise value. Lock these in:

• Point-of-use precleaning must begin immediately after the procedure, before bioburden dries.
• Leak testing is performed before manual cleaning/immersion to detect channel breaches.
• MEC test strips verify HLD potency before each use, with results logged.
• Drying: forced filtered/instrument air plus 70-90% isopropyl alcohol flush, then store in a drying/storage cabinet; many facilities follow hang-time limits (commonly cited as 7 days or up to ~31 days in validated drying cabinets, per IFU and facility policy).

Mix domains so you can switch fast

The exam interleaves topics; it will not tell you the next item is about drying versus documentation. So after the early targeted days, switch to mixed sets that force you to jump between cleaning chemistry, automated endoscope reprocessor (AER) operation, transport, storage, and quality monitoring. This trains the mental gear-shift you need on test day.

Use a one-line rule per recurring miss. Good final-week rules look like:

• "Clean before disinfect — soil blocks HLD; never reverse the order."
• "Leak test first, fully, with the scope angulated through all positions."
• "Damaged scope or failed leak test → remove from service, tag, send for repair."
• "AER cycle aborts → do not assume disinfection; reprocess from cleaning."

What NOT to do in the last week

• Do not start a new textbook, video series, or question bank you have never used; unfamiliar formats add anxiety without coverage.
• Do not cram the night before — fatigue costs more points than one more review hour gains.
• Do not drill only your strong areas because they feel good; that is comfort, not progress.
• Do not memorize one vendor's IFU as if it were universal — the correct exam answer is almost always "follow the manufacturer's IFU," because reprocessing parameters are device-specific. A scenario where two scopes need different cleaning adapters is testing exactly this principle: adapters and channel maps differ by model, so an adapter that fits a gastroscope may not seal a bronchoscope channel, leaving it uncleaned.

A one-page memory sheet to rebuild from memory each morning

The most efficient final-week drill is the blank-page reproduction: each morning, write the standard reprocessing sequence and its critical parameters from memory, then check it against your notes. If you can reproduce it cold, it is exam-ready; the gaps you leave blank are exactly where to spend the day's review.

Reproduce this skeleton:

1. Point-of-use precleaning — wipe exterior, flush channels with IFU detergent immediately, before drying.
2. Leak test — before immersion; angulate through all positions; failed test removes scope from service.
3. Manual cleaning — IFU detergent, correct adapters and brushes, brush every channel, soak per IFU time.
4. Rinse — remove detergent residue.
5. High-level disinfection or sterilization — verify MEC before use; observe full contact time and temperature.
6. Rinse and dry — critical/final rinse water, forced filtered air, 70-90% alcohol flush.
7. Storage — vertical hang or validated drying cabinet, documented.

Standards bodies to keep straight

The exam may attribute a practice to the wrong authority as a distractor. Map each source so you do not misattribute:

When a stem and an answer conflict, the IFU is the tiebreaker; when the IFU is silent, defer to AAMI ST91 and your facility policy. Memorizing this hierarchy answers a surprising share of "which is the BEST source" items without any rote fact recall. A final last-week habit: each evening, run a five-minute self-quiz on the numbers table above without looking — MEC frequency, leak-test timing, drying-cabinet hang times, point-of-use timing.

These few values appear repeatedly across cleaning, disinfection, and storage items, so a candidate who has them automatic recovers several scored questions that a fuzzy recall would lose, and does it in seconds rather than burning the pacing clock.
