Multiple Choice
1. Which of the following would be a sign of an infection?
A. muscle aches
B. headache
C. fever (Measurable with a thermometer, Objective not subjective)
D. nausea
2. Which of the following is an example of a noncommunicable infectious disease?
A. infection with a respiratory virus
B. food poisoning due to a preformed bacterial toxin in food (Nontransferable person to
person)
C. skin infection acquired from a dog bite
D. infection acquired from the stick of a contaminated needle
3. During an oral surgery, the surgeon nicked the patient’s gum with a sharp instrument.
This allowed Streptococcus, a bacterium normally present in the mouth, to gain access to

er as
heart). Which type of disease is this?
co

eH w
B. nosocomial
o.
C. vectors
D. zoonotic rs e

4. Which period is the stage of disease during which the patient begins to present general
signs and symptoms?
A. convalescence
o
B. incubation
aC s
C. illness
vi y re
D. prodromal
5. A communicable disease that can be easily transmitted from person to person is which
type of disease?
A. contagious
ed d
B. iatrogenic
ar stu
C. acute
D. nosocomial
6. Which of the following is a pathogen that could not be identified by the original Koch’s
is
postulates?
A. Staphylococcus aureus
Th
B. Pseudomonas aeruginosa
C. Human immunodeficiency virus
D. Salmonella enterica serovar Typhimurium
7. Pathogen A has an ID50 of 50 particles, pathogen B has an ID50 of 1,000 particles, and
sh
pathogen C has an ID50 of 1 × 106 particles. Which pathogen is most virulent?
A. pathogen A (Most extreme, harmful)
B. pathogen B
C. pathogen C
8. Which of the following choices lists the steps of pathogenesis in the correct order?
