B) The infection was not present at the time of admission.
C) The six elements of the chain of infection remain intact.
D) The patient is colonized with drug-resistant organisms.: B
2. What are the 6 elements in the chain of infection?: 1) An infectious agent or pathogen (e.g.,
bacteria, viruses, fungi, protozoa).
2) A reservoir or source for pathogen growth (e.g., humans, animals, food, water, insects, inanimate objects).
3) A portal of exit from the reservoir (e.g., skin and mucous membranes, respiratory tract, urinary tract, gastrointestinal
tract, reproductive tract, and blood).
4) A mode of transmission (e.g., hands of health care workers, equipment used within the environment, droplet nuclei).
5) A portal of entry to the host (e.g., skin and mucous membranes, respiratory tract, urinary tract, gastrointestinal tract,
reproductive tract, and blood).
6) A susceptible host.
3. It is determined that the patient has developed a health care-associated
infection of Pseudomonas pneumonia that developed from the presence of
contaminated water and a dirty health care environment. What measures can
be taken to help break the chain of infection? (Select all that apply.)
A) Performing hand hygiene before and after contact with the patient
B) Discarding standing water and rinsing cups after use.
C) Teaching the patient and family about the source and transmission of infec-
tions, the reason for susceptibility, and infection-control principles
D) Having the patient wear an oxygen mask: A B C
4. Aseptic technique: refers to practices and procedures that help reduce the risk for infection. The two types
of aseptic technique nurses practice are medical and surgical asepsis.
5. Medical Aesepsis: also known as clean technique, includes procedures that reduce the number of organisms
and prevent their transfer.
Examples are of principles of hand hygiene, barrier techniques (e.g. applying gloves or gowns), and routine environ-
mental cleaning

6. Surgical Asepsis: Surgical technique and aseptic practices maintain an area that is free from pathogenic
organisms, serve to isolate an operative area from the unsterile environment, and maintain a sterile field for surgery
and invasive procedures.
7. ________ reduces the number of microorganisms present
Medical asepsis or Surgical asepsis: Medical Asepsis
8. Eliminates microorganisms from an area.
Medical asepsis or Surgical asepsis: Surgical Asepsis
9. Risk factors for health care-acquired infection include:: Exposure to microorganisms
within a health care facility
A patient's length of stay
Persons with chronic illness
Persons with compromised immunity
Multiple invasive treatments
Treatment with multiple antibiotics for long periods of time
10. A patient is discharged home with a follow-up plan for continued weekly
chemotherapy treatments on an outpatient basis. Three days later, the patient
has increased weakness and refuses to eat. Concerned, the patient's family
brings the patient to the hospital. It is a busy Friday night in the emergency
room, and the patient sits in an overcrowded waiting room for 3 hours before
being seen by a physician. An intravenous line (IV) is started to improve the
patient's fluid and electrolyte status, and blood is drawn for further testing.
A) Being discharged home
B) Having chemotherapy
C) Being malnourished
D) Overcrowded health care facility

sweat), nonintact skin, and mucous membranes
12. What are standard percautions?: are for the care of all patients regardless of risk or presumed
infection status. Standard precautions are the primary strategies for prevention of infection transmission and apply to

contaminated with these potentially infectious materials.

airflow room.

ling transmission of infection?: Hand hygiene

hand hygiene and ________.: Wear Gloves
21. What are the 5 instances in which the RN should perform hand hygiene?: 1)
Before touching a patient
, Infection Control (ISB & Post Tests)

2) Before clean/aseptic procedures (e.g. insertion of invasive devices, hygiene care),
3) After body fluid exposure/risk (e.g. contacted during bathing, dressing changes, specimen collection),
4) After touching a patient
5) After touching patient surroundings (e.g. overbed table, bed linen, IV pump). Also perform hand hygiene after
removing gloves.
22. According to the Centers for Disease Control and Prevention (CDC) Guide-
lines, an alcohol-based hand rub is used for routine decontamination in which
of the following situations? Select all that apply.
A) When a patient's mucus accidentally gets on the nurse's hand.
B) Before having direct contact with patients.
C) After contact with objects in the immediate vicinity of a patient.
D) After a patient develops a skin tear and blood is present on both the patient
and the nurse's hands.
E) After removing gloves.: B C E
23. What should the nurse inspect on their hands before performing HH (Hand
Hygiene): Inspect surface of hands for breaks or cuts in skin or cuticles
