CIS Specialty Instrumentation Sets Questions and Answers 2 — Questions and Answers
Question 1: What is a key consideration when assembling an orthopedic total joint replacement instrument set?
- Instruments can be placed randomly
- Instruments must be organized by surgical sequence with proper sizing progression and balanced weight (Correct answer)
- Only implants need to be included
- No special organization required
Correct answer: Instruments must be organized by surgical sequence with proper sizing progression and balanced weight
Sets must be organized by surgical sequence with sizing progressions, heavy items balanced across trays, and weight within limits for effective sterilization.
Total joint sets require sequential organization by surgical steps, sizing progressions in clear order, heavy components distributed across trays to stay within 25-pound limits, and trial versus final implants in separate containers.
Question 2: Why do ophthalmic instruments require separate handling from general surgical instruments?
- They are more expensive
- Their extremely delicate tips and precision mechanisms can be damaged by standard handling processes (Correct answer)
- They do not need sterilization
- They react with standard instruments
Correct answer: Their extremely delicate tips and precision mechanisms can be damaged by standard handling processes
Ophthalmic instruments have extremely fine tips and precision mechanisms that can be damaged by mechanical forces and handling practices appropriate for standard instruments.
Ophthalmic instruments require tip protection (tips as fine as 0.1mm), separate processing from heavier instruments, gentle cleaning methods, individual holders, magnified inspection, and lightweight specialized trays.
Question 3: What special processing is required for neurosurgical craniotomy instruments?
- No special processing
- Meticulous bone debris removal from drill components and sharp-edge verification on curettes and dissectors (Correct answer)
- Only alcohol wiping
- Always disposable
Correct answer: Meticulous bone debris removal from drill components and sharp-edge verification on curettes and dissectors
Craniotomy instruments require thorough bone debris removal from drill burrs and edge verification on curettes and dissectors for safe work near brain tissue.
High-speed drill burrs accumulate bone paste in flutes that is extremely difficult to remove. Curette edges must be sharp since dull instruments require more force near brain tissue. Bipolar forceps tips must be precisely aligned for accurate cautery of delicate cerebral vessels.
Question 4: How should loaner or consignment instrument sets be processed upon arrival?
- Use directly as received
- Inspect, decontaminate, assemble, and sterilize through the facility's standard cycle (Correct answer)
- Only sterilize if visibly dirty
- The vendor handles sterilization
Correct answer: Inspect, decontaminate, assemble, and sterilize through the facility's standard cycle
All loaner instruments must be received with adequate time for complete inspection, decontamination, assembly, and sterilization regardless of vendor claims.
Facilities should require 24-48 hours advance delivery. All items undergo complete reprocessing regardless of vendor claims. IFUs must accompany the set. Many facilities require BI testing for loaner sets. Instruments arriving without adequate time should not be used.
Question 5: What is the purpose of a preference card or pick list for specialty instrument sets?
- To display the manufacturer's catalog
- To document the specific instruments and supplies a surgeon requires for a particular procedure (Correct answer)
- To track repair history
- To calculate procedure cost
Correct answer: To document the specific instruments and supplies a surgeon requires for a particular procedure
Preference cards document each surgeon's specific instrument, supply, and equipment requirements, ensuring correct specialty sets are prepared for each case.
Preference cards document instrument sets, supplemental instruments, supplies, sutures, and equipment needs for each surgeon and procedure. Accurate cards reduce case delays, instrument returns, and unnecessary opening of sterile items.
Question 6: What challenge does processing instruments from bariatric surgery present?
- Identical to standard instruments
- Extended-length instruments require longer cleaning brushes, specialized tray configurations, and thorough lumen cleaning (Correct answer)
- Cannot be sterilized
- Only require external cleaning
Correct answer: Extended-length instruments require longer cleaning brushes, specialized tray configurations, and thorough lumen cleaning
Bariatric instruments are extended-length, requiring longer brushes, specialized trays, and extra attention to ensure complete cleaning of longer channels.
Extended instruments may be 50% longer than standard versions, requiring purpose-built brushes, custom trays, more flushing solution for longer lumens, and adjusted loading patterns. They are also heavier, contributing to weight limits being reached sooner.
