#1
Which of the following is a common mode of transmission for healthcare-associated infections (HAIs)?
Direct contact
ExplanationTransmission occurs through physical contact with infected individuals or contaminated surfaces.
#2
What is the primary purpose of hand hygiene in infection control?
To reduce the spread of microorganisms
ExplanationHand hygiene helps to minimize the transfer of harmful microorganisms from one person to another.
#3
Which of the following is an example of a Healthcare-associated infection (HAI)?
Pneumonia acquired during hospitalization
ExplanationPneumonia developed while hospitalized is an example of an HAI, indicating infection acquired during healthcare delivery.
#4
What is the recommended duration for handwashing with soap and water according to WHO guidelines?
At least 20 seconds
ExplanationWashing hands for a minimum of 20 seconds effectively removes dirt and pathogens, as per WHO recommendations.
#5
What is the term used to describe an infection acquired by a patient while receiving treatment in a healthcare facility?
Hospital-acquired infection
ExplanationInfections contracted during healthcare interventions are termed hospital-acquired infections, emphasizing their association with healthcare settings.
#6
Which organization provides guidelines and recommendations for infection control practices in healthcare settings?
World Health Organization (WHO)
ExplanationWHO offers comprehensive guidelines to promote effective infection control in healthcare environments.
#7
What is the appropriate action to take if a healthcare worker experiences a needlestick injury while providing care?
Report the incident immediately and seek medical evaluation
ExplanationPrompt reporting and medical evaluation are crucial to prevent potential infections following a needlestick injury.
#8
Which of the following is NOT a mode of transmission for Clostridioides difficile infection (CDI)?
Airborne transmission
ExplanationCDI primarily spreads through fecal-oral route and contact with contaminated surfaces, not through airborne particles.
#9
What is the recommended personal protective equipment (PPE) for healthcare workers when entering the room of a patient with known or suspected tuberculosis (TB)?
Gloves, gown, N95 respirator, and eye protection
ExplanationThese PPE items are necessary to minimize exposure to airborne TB pathogens and prevent infection transmission.
#10
What is the purpose of isolation precautions in infection control?
To prevent the transmission of infectious agents between patients and healthcare workers
ExplanationIsolation precautions aim to contain infectious agents, preventing their spread between patients and healthcare staff.
#11
Which of the following is an example of a Standard Precaution for infection control?
Properly disposing of sharps in designated containers
ExplanationProper disposal of sharps reduces the risk of needlestick injuries and potential transmission of infections.
#12
What is the role of environmental cleaning in infection control?
To reduce the number of microorganisms on surfaces
ExplanationThorough cleaning of surfaces helps to eliminate pathogens, reducing the risk of transmission and maintaining a hygienic environment.
#13
What is the recommended method for sterilizing heat-sensitive medical devices?
Ethylene oxide gas sterilization
ExplanationEthylene oxide gas sterilization is effective for heat-sensitive devices, ensuring complete microbial eradication.
#14
Which of the following is a characteristic of a surgical site infection (SSI)?
May require antibiotic treatment and surgical intervention
ExplanationSSIs often necessitate antibiotic therapy and sometimes additional surgical procedures to resolve the infection and prevent complications.
#15
Which of the following is a characteristic of a central line-associated bloodstream infection (CLABSI)?
Can lead to serious complications such as sepsis
ExplanationCLABSI complications can be severe, including systemic infections like sepsis, highlighting the importance of prevention measures.
