According to the animation, surgical infections account for what percentage of nosocomial infections?
20%
2.
As a health care worker, I am keenly aware of how important it is to avoid harming my patients. I worry about inadvertently transmitting an infectious disease to an already compromised individual. According to the CDC, what is the MOST important thing I can do to avoid this?
Wash my hands before interacting with any patient.
A dog develops a diarrheal disease after drinking water from a creek during a hike with his owner. Which of the following best describes this method of disease transmission?
vehicle transmission
Epidemiology is defined as the study of
where and when a disease occurs, and how it is transmitted.

8.
Expected prevalence of a disease is
the expected occurrence of a disease based on past observations.
The following choices list several types of diseases, along with factors that may contribute to their emergence. Which disease and associated factor do NOT match?
emergence of avian influenza A (H5N1): use of antibiotics
The health of the patient
should be the primary concern of the healthcare worker.
How can health care workers reduce the occurrence of nosocomial infections?
Practice more stringent aseptic techniques
9.
How can surgeons help to limit nosocomial infections?
They should perform surgeries and invasive procedures only when absolutely necessary.
10.
How might a patient who is not being treated with an antibiotic still be exposed to an antibiotic?
Antibiotics can be used in aerosols, thereby entering the environment.
11.
If a disease occurs at a fairly stable rate, it is said to be
endemic.
12.
If a patient notices a healthcare worker not following suggested precautions,
they should immediately bring it to the attention of the healthcare worker.
13.
In the last segment of the animation, how many regions of the world experience the pandemic during April of year four?
Five
14.
In the last segment of the animation, when does the first epidemic occur?
January of year three
15.
In the sixth segment of the animation, why is the disease epidemic in North America?
The disease occurs at a higher rate than what would normally be expected in this region.
16.
Koch's postulates established criteria for proving that a specific organism causes a specific disease. Which of the following is NOT one of the criteria given by Koch's postulates?
The pathogen must be isolated from inoculated animals and must be different from the original organism.
17.
Malaria is an infectious disease caused by infection with a protozoan. In certain tropical regions, malaria is constantly present. We would say that malaria is a(n) _________ disease in these regions.
endemic
18.
A patient acquires an infection by touching a contaminated door handle. Which mode of transmission best describes this scenario?
indirect contact transmission
19.
Plague is transmitted through the bite of an infected flea. Which of the following best describes this mode of transmission?
vector transmission
20.
What is the role of epidemiology?
To learn how to treat and prevent various diseases.
21.
What type of nosocomial infection is likely to arise from intravenous catheterizations?
Bacteremia
When aerosols containing pathogens spread disease from a distance of less than one meter, it is considered
contact transmission.
23.
Which is an example of vehicle disease transmission?
The presence of Listeria on undercooked chicken served for dinner
24.
Which of the following characteristics of a catheter should be considered, to help minimize the spread of nosocomial infections?
Single-use
25.
Which of the following is a fungal zoonosis that can be transmitted by direct contact?
ringworm
26.
Which of the following is an example of the symbiotic relationship known as mutualism?
E. coli within the large intestine
27.
Which of the following is classified as a latent disease?
shingles
28.
Which of the following is considered a major category of transmission of disease?
Contact, vehicle, and vector transmission
29.
Which of the following statements about the development of infectious diseases is correct?
The period of convalescence is the time during which the person regains health and fully recovers (back to the pre-disease state).
30.
Which of the following statements concerning pathology, infection, and disease is true?
Pathology refers to the study of structural and functional changes that occur in the body as a result of a disease.
31.
Which of the following statements is true regarding hand washing?
Frequent and proper hand washing should be routinely done by patients and by healthcare workers, both prior to and after interaction.

33.
Which of the following would be considered a fomite?
An infected toy
34.
Which of the following would be considered a vector?
A fly carrying disease from fecal matter to food
35.
Why are invasive procedures likely to increase the risk of nosocomial infections?
These procedures allow microbes from the skin to enter the bloodstream of the patient....
