MODULE 1-INFECTION CONTROL
EXAM
Why is it critical for health care workers to apply infection control practices in the
workplace? - Correct Answers -Failure to prevent the spread of an infectious disease
can cause unnecessary pain, suffering, and even death. Regulatory standards have
been developed to prevent pathogens from being passed from patient to patient, staff to
patient, patient to staff, or staff to staff.
What theories and discoveries led up to microbiology as we know it today? - Correct
Answers -The significant discovery was the microscope. It was invented by Anton van
Leeuwenhoek in the 1600s. In the 1800s, Louis Pasteur, a French biochemist and
physicist, used the microscope to develop the germ theory, which stated that specific
microorganisms called bacteria cause specific diseases in both humans and animals.
Name and describe the characteristics of each of the five types of infectious microbes.
Include examples of diseases caused by each type - Correct Answers -* Bacteria are
one-celled plants and can be either pathogenic or nonpathogenic. Bacteria are
characterized by their shapes; they can be round, rod, or spiral. Diseases: abscesses,
boils, wound infections, urinary tract infections, pneumonia, rheumatic fever, severe
sore throat, tuberculosis, tetanus, whooping cough, food poisoning, diphtheria, typhoid
fever, syphilis, and cholera.
* Viruses are the smallest of the microbes. Viruses are not whole cells, and they depend
on host cells for food, nutrients, and a means of reproduction. Diseases: common cold,
flu, pneumonia, chicken pox, croup, hepatitis B, AIDS, measles, mumps, warts, herpes,
and polio.
* Fungi are a large group of simple plants. Two forms of fungi are potential pathogens:
yeasts and molds. Yeasts are one-celled and molds are multi-celled plants. Both are
present everywhere. Diseases: ringworm, scalp and skin infections, systemic infections.
* Rickettsia are smaller than bacteria and have rod or spherical shapes. Rickettsia must
live in other cells. Diseases: several types of typhus and Rocky Mountain spotted fever.
* Protozoa are the only microorganisms classified as animals. They are one-celled,
plentiful in the environment, and reside in and on the body. Diseases: dysentery,
trichomonas, toxiplasmosis, pneumonia, and malaria.
What are the elements in the chain of infection, and how can it be broken? - Correct
Answers -* The infectious agent
* Reservoir host of the agent
* Portal of exit from the host
