1. Which of the following is the absence of disease-producing microorganisms?
A. Sepsis
B. Asepsis
C. Contamination
D. Isolation
ANS: B
Asepsis is the absence of microorganisms that produce disease. It might also be defined as
the prevention of infection by maintaining sterile conditions. Sepsis, conversely, is the
presence of pathogenic microorganisms or their toxins in blood or tissues.
PTS: 1
2. Microorganisms move from place to place by various means in a cyclical manner. What are the five elements in the
cycle of infection? A. Reservoir, exit, transmission, infection, and susception
B. Isolation, wound, contamination, infection, and sterilization
C. Infection, contamination, decontamination, transmission, and exit D.
Susception, reservoir, wound, isolation, and exit
ANS: A
Microorganisms require a place where they can grow and reproduce (reservoir), a means
by which they can leave the host (exit), a mode of passage from one person to another
(transmission), the ability to enter a person (infection), and a host who is susceptible to
them (susception).
PTS: 1
3. What are the most common modes of transmission of pathogenic microorganisms?
A. Gloves, masks, and gowns
B. Tables, chairs, and beds
C. Water and food
D. Contact, droplet, airborne
ANS: DTEST BANK FOR PIERSON AND FAIRCHILD'S PRINCIPLES AND TECHNIQUES OF PATIENT CARE 6TH EDITION
BY FAIRCHILD
The primary means of transmission of pathogenic microorganisms are through contact,
droplets, and the air. The healthcare worker must be aware of the barriers (such as gloves,
masks, and gowns) used to prevent transmission of pathogens via each of these modes.
PTS: 1
4. What is the term used to describe practices that render and keep objects and areas free of all microorganisms,
preventing the spread of infection to a patient?
A. Surgical asepsis
B. Medical asepsis
C. Hospital asepsis
D. Clinical asepsis
ANS: A
Surgical asepsis techniques are used to exclude all microorganisms before they can enter a
surgical wound or contaminate a sterile field prior to or during surgery. Techniques of
medical asepsis, on the other hand, are designed to keep pathogens confined to a specific
area, object, or person.
PTS: 1
5. What is the most important activity that caregivers should perform before and after contact with a patient to control
infection?
A. Documentation
B. Hand hygiene
C. Linen changing
D. Gown changing
ANS: B
The most common method of pathogen transmission is by direct contact; therefore, the
habitual use of proper hand hygiene techniques is the single most effective way to protect
the patient and the caregiver.
PTS: 1
6. Which of the following are advantages of hand rubbing with alcohol-based rubs? A. It is more accessible than sinks.
B. It requires less time to use than soap and water.
C. It causes less damage to the skin than soap and water when an emollient has been added.
D. All of the above are advantages.
ANS: D
Hand rubbing, especially using alcohol-based rubs from a wall-mounted dispenser, has
several advantages over hand washing. For example, it requires less time to use, it is more
effective than soap and water, it is more accessible than sinks, it reduces bacterial counts
on hands significantly, and it often causes less damage to the skin than soap and water. [Show Less]
