1. Which statement best defines hand hygiene as a fundamental
component of infection prevention and control in healthcare settings?
A. The process of wearing gloves whenever a healthcare worker contacts a
patient
B. The practice of removing or reducing microorganisms on the hands
through appropriate handwashing or hand antisepsis
C. The process of sterilizing all equipment before patient contact
D. The practice of using antibiotics before performing invasive procedures
Answer: B. The practice of removing or reducing microorganisms on the
hands through appropriate handwashing or hand antisepsis
,Rationale: Hand hygiene includes actions such as handwashing with soap
and water and using an appropriate alcohol-based hand rub to remove or
reduce microorganisms on the hands. It is one of the most important
measures for preventing transmission of infections in healthcare
environments.
2. Which microorganism transmission pathway is most directly
interrupted by effective hand hygiene?
A. Transmission through contaminated hands between patients and surfaces
B. Transmission through inherited genetic material
C. Transmission through ultraviolet radiation
D. Transmission through mosquito reproduction
Answer: A. Transmission through contaminated hands between patients
and surfaces
Rationale: Healthcare workers' hands can become contaminated through
contact with patients, body fluids, equipment, and environmental surfaces.
Effective hand hygiene interrupts this chain of transmission by removing or
killing microorganisms before they are transferred elsewhere.
3. According to the World Health Organization's concept of the “Five
Moments for Hand Hygiene,” when should a healthcare worker
perform hand hygiene immediately before touching a patient?
,A. After touching the patient's surroundings
B. After removing personal protective equipment only
C. Before touching a patient
D. Only after completing all patient care activities
Answer: C. Before touching a patient
Rationale: The first WHO hand hygiene moment is “before touching a
patient.” This protects the patient from microorganisms that may be
present on the healthcare worker's hands.
4. Which situation represents the WHO “before a clean or aseptic
procedure” moment for hand hygiene?
A. Before inserting a urinary catheter
B. After shaking a patient's hand
C. After leaving the patient's room without touching anything
D. Before entering the hospital cafeteria
Answer: A. Before inserting a urinary catheter
Rationale: Aseptic procedures require protection against introducing
microorganisms into normally sterile body sites or vulnerable areas. Hand
hygiene must therefore be performed immediately before such procedures.
5. Which of the following is an example of the WHO “after body fluid
exposure risk” moment?
, A. Before reading a patient's medical record
B. After handling a wound dressing contaminated with wound drainage
C. Before entering the hospital
D. After attending a staff meeting
Answer: B. After handling a wound dressing contaminated with wound
drainage
Rationale: Hand hygiene is required after body fluid exposure or exposure
risk because microorganisms from body fluids can contaminate the
healthcare worker's hands and subsequently spread to other people or
surfaces.
6. A nurse finishes taking a patient's blood pressure and then leaves the
bedside. Which WHO hand hygiene indication applies most directly?
A. Before touching a patient
B. Before a clean procedure
C. After touching a patient
D. Before touching the patient's surroundings
Answer: C. After touching a patient
Rationale: Hand hygiene should be performed after patient contact to
remove microorganisms acquired during care and prevent their transfer to
other patients, healthcare workers, equipment, or environmental surfaces.
