Question

which of the following procedures will the medical assistant use to clean blood pressure cuffs and reflex hammers?

multiple choice

sterilization

purification

ultrasonic cleaning

disinfection

sanitization

Explanation:

Classify the medical instruments

Using the Infection Control Protocols knowledge point, we classify blood pressure cuffs and reflex hammers. Under the Spaulding classification system, these are noncritical items because they only come into contact with intact skin.

Determine the required level of infection control

Using the Aseptic Procedures knowledge point, noncritical items that touch only intact skin do not require sterilization or high-level disinfection. Instead, they require low-level disinfection or sanitization. Specifically, standard clinical guidelines state that blood pressure cuffs and reflex hammers should be sanitized (or cleaned with a low-to-intermediate level disinfectant) to remove pathogens and organic matter. Sanitization is the process of reducing the number of microorganisms on a clean surface to a safe level.

Evaluate the given options

• sterilization: Destroys all microbial life; used for critical items (e.g., surgical instruments).
• purification: Not a standard clinical term for instrument reprocessing.
• ultrasonic cleaning: A method of sanitization/pre-cleaning using sound waves, typically for delicate jointed instruments before sterilization.
• disinfection: Destroys pathogenic microorganisms but not necessarily spores; typically used for semi-critical items or hard surfaces.
• sanitization: The washing/cleaning process that reduces microbes to safe levels; standard for noncritical items like blood pressure cuffs and reflex hammers.

Answer:

• (A) sterilization
• (B) purification
• (C) ultrasonic cleaning
• (D) disinfection
• (E) sanitization (Correct answer)
