MNT Infection Control & Sterilization

Question 1

What is the correct order of instrument processing in a medical nail care setting?

Accepted Answer

Clean, disinfect, sterilize

Answer

Instruments must first be cleaned (removing visible debris), then disinfected (eliminating most pathogens), and finally sterilized (destroying all microorganisms including spores) for the highest level of safety.

Question 2

What type of sterilization is most commonly used for metal nail care instruments?

Accepted Answer

Autoclave (steam sterilization under pressure)

Answer

Autoclaves use pressurized steam at 121°C (250°F) for 15-30 minutes to achieve sterilization, killing all microorganisms including bacterial spores. This is the gold standard for reusable metal instruments.

Question 3

What are Standard Precautions in healthcare settings?

Accepted Answer

Infection control practices applied to all patient care regardless of suspected or confirmed infection status

Answer

Standard Precautions assume all blood and body fluids are potentially infectious, requiring hand hygiene, PPE, safe injection practices, and proper instrument processing for every client encounter.

Question 4

What should a medical nail technician do if they accidentally cut a client's skin during a procedure?

Accepted Answer

Stop the procedure, apply pressure with sterile gauze, clean the wound with antiseptic, apply appropriate dressing, and document the incident

Answer

Any breach of skin integrity requires immediate attention: stop work, control bleeding, clean the wound, apply sterile dressing, document the incident, and follow bloodborne pathogen exposure protocols if applicable.

Question 5

What is the purpose of biological indicator (spore test) monitoring for autoclaves?

Accepted Answer

To verify that the autoclave is actually achieving sterilization by testing with highly resistant bacterial spores

Answer

Biological indicators contain spores of Geobacillus stearothermophilus, one of the most heat-resistant organisms. If these spores are killed, the autoclave is confirmed to be achieving true sterilization.
