Which of the following adjectives best describes a surgical procedure that is free of microbial contaminants?
a. Disinfected
b. Sanitized
c. Degermed
d. Aseptic

Guida verificata passo dopo passo

Step 1: Understand the meaning of each adjective related to microbial control. 'Disinfected' refers to the process of eliminating many or all pathogenic microorganisms, except bacterial spores, on inanimate objects.

Step 2: 'Sanitized' means reducing the number of microorganisms to a safe level as judged by public health standards, often used for cleaning surfaces or utensils.

Step 3: 'Degermed' refers to the removal of microbes from a limited area, such as skin, typically by mechanical means combined with antiseptics.

Step 4: 'Aseptic' describes a condition or procedure that is completely free of microbial contamination, often used in surgical or laboratory settings to prevent infection.

Step 5: Since the question asks for the adjective that best describes a surgical procedure free of microbial contaminants, identify that 'aseptic' is the correct term because it implies the absence of all microbes during the procedure.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Aseptic Technique

Aseptic technique refers to procedures performed under conditions that prevent contamination by pathogens or microbes. In surgery, aseptic conditions ensure that the environment, instruments, and personnel do not introduce microbes, maintaining sterility throughout the procedure.

Disinfection vs. Sterilization

Disinfection involves reducing or eliminating pathogenic microorganisms on surfaces but may not kill all spores. Sterilization, often implied by aseptic conditions, means complete removal or destruction of all microbial life, including spores, which is critical for surgical procedures.

Types of Disinfectants

Sanitization and Degerming

Sanitization reduces microbial numbers to safe public health levels, often on inanimate objects, while degerming is the mechanical removal of microbes from skin or tissue, such as handwashing. Neither guarantees a completely microbe-free environment like aseptic conditions do.
