Pneumonia acquired in a hospital setting
ExplanationNosocomial infections are those acquired in healthcare facilities.
#2
What is the primary goal of hand hygiene in healthcare settings?
To prevent the spread of infection
ExplanationHand hygiene reduces the transmission of pathogens.
#3
Which of the following is an example of a bloodborne pathogen?
Hepatitis B virus
ExplanationBloodborne pathogens are transmitted through blood.
#4
What is the recommended method for disposing of sharps, such as needles and scalpels, after use?
Place them in a puncture-resistant container labeled as biohazardous waste
ExplanationProper disposal reduces the risk of needlestick injuries and exposure to bloodborne pathogens.
#5
Which of the following is NOT an example of a healthcare-associated infection (HAI)?
Influenza contracted in a community setting
ExplanationHAIs are acquired in healthcare settings.
#6
Which of the following is an example of a barrier precaution used in infection control?
Wearing gloves during patient care
ExplanationBarrier precautions create a physical barrier between the healthcare worker and potentially infectious material.
#7
Which of the following is an example of aseptic technique?
Using sterile gloves during surgery
ExplanationAseptic techniques aim to prevent contamination.
#8
What is the purpose of sterilization in infection control?
To kill all microorganisms including spores

#9
What is the recommended duration for surgical hand scrubbing with an antimicrobial soap?
2 minutes
ExplanationTwo minutes is the standard duration for effective surgical hand scrubbing.
#10
Which of the following is NOT a method of transmission for healthcare-associated infections (HAIs)?
Vector-borne transmission
ExplanationHAIs are not typically transmitted via vectors.
#11
What is the primary mode of transmission for Clostridioides difficile (C. diff) infection?
Contact transmission
ExplanationC. diff is primarily transmitted through contact with contaminated surfaces or objects.
#12

ExplanationIsolation precautions are part of Transmission-Based Precautions.
#14
What is the purpose of using barriers such as gloves, gowns, and masks in infection control?
To prevent the transmission of infectious agents
ExplanationBarriers create a physical barrier between healthcare workers and pathogens.
#15
Which of the following is an example of a High-Level Disinfectant (HLD)?
Ethylene oxide gas
ExplanationHLDs are capable of killing all microorganisms, including spores.
#16
What is the purpose of environmental cleaning in infection control?
To eliminate microorganisms from surfaces and equipment
