What is the purpose of a surgical hand scrub compared to routine hand hygiene?
Answer: It reduces microbial counts for an extended period to minimize surgical site infection risk
A surgical hand scrub achieves a prolonged reduction in microbial flora on the hands, providing extended protection in case a glove tears during a surgical procedure.
Which of the following is a correct description of contact transmission of infection?
Answer: Direct physical contact or indirect contact via contaminated objects (fomites)
Contact transmission occurs through direct physical contact with an infected person or indirect contact with contaminated surfaces or objects known as fomites.
A patient with active pulmonary tuberculosis should be placed in which type of room?
Answer: An airborne infection isolation room (AIIR) with negative air pressure
Active pulmonary tuberculosis requires an airborne infection isolation room (AIIR) with negative air pressure to prevent airborne particles from escaping into the corridor.
Which of the following is considered high-level disinfection?
Answer: Soaking semi-critical items in glutaraldehyde solution
High-level disinfection, achieved by soaking semi-critical items in chemical agents such as glutaraldehyde, destroys all microorganisms except high numbers of bacterial spores.
The 'susceptible host' link in the chain of infection refers to which concept?
Answer: A person whose immune defenses cannot prevent infection
A susceptible host is an individual whose immune system is unable to resist infection due to factors such as age, immunocompromised status, or underlying disease.
