- DExam table surface
About this question
Which items need sterilization rather than routine low-level disinfection? CCMA infection-control questions test the Spaulding-style idea: critical instruments that enter sterile tissue or the bloodstream need a higher kill standard than noncritical surfaces. Read the wording and clinical context closely; those details determine the NHA CCMA competency being tested.
This item asks you to identify what requires sterilization after invasive procedure use. Instruments that enter a sterile field generally require sterilization that destroys all microorganisms including spores, not just a wipe with disinfectant. Disinfection reduces many pathogens but does not reliably kill all spores. Clean first, then disinfect or sterilize based on item risk. For sterilization vs disinfection invasive instruments, compare the best choice with its closest look-alike before moving to the next practice item.
Reveal answer & explanationShow
Correct answer
- ABlood pressure cuff
- BStethoscope diaphragm
- CProcedure instrument entering sterile fieldCorrect
- DExam table surface
Basic rationale
Instruments contacting sterile tissue or entering invasive fields require sterilization.
Option explanations
- A: Noncritical equipment is typically disinfected, not sterilized.
- B: Usually cleaned with low-level disinfectant.
- C: Correct. Critical instruments require sterilization.
- D: Environmental surfaces are disinfected.
Deep Analysis
Core logic
Reprocessing level depends on intended contact risk. Critical instruments require sterilization to eliminate microbial burden adequately.
Distractor analysis
A: Incorrect because blood pressure cuffs are noncritical items and usually disinfected. B: Incorrect because stethoscopes are generally low-level disinfected. D: Incorrect because exam tables are environmental surfaces requiring disinfection.
Exam trap
Classify by patient contact level, not by how serious the case feels.
Memory tip
Critical instrument equals sterilization.
