1. The smallest microorganisms capable of causing infection are:
A) Bacteria
B) Fungi
C) Viruses
D) Protozoa
, Page 2 of 207
Answer: C
Viruses are the smallest microorganisms, ranging from 0.02 to 0.3 micrometers. They are obligate
intracellular parasites that require a host cell to replicate and are not affected by antibiotics.
2. Which type of microorganism causes infections such as tuberculosis and leprosy?
A) Gram-positive bacteria
B) Gram-negative bacteria
C) Acid-fast bacteria

3. The time between the invasion of a pathogen and the appearance of symptoms is called the:
A) Prodromal period
B) Incubation period
C) Convalescent period
D) Acute period
Answer: B
The incubation period is the time between the initial entry of a pathogen into the body and the
appearance of the first signs or symptoms of infection. This period varies widely depending on the
pathogen.

A) An infected patient
B) A contaminated surgical instrument
, Page 4 of 207
C) A droplet from a cough
D) An insect vector
Answer: B
A fomite is an inanimate object that can transmit infectious agents. Contaminated surgical instruments,
linens, and medical equipment are common fomites in healthcare settings.
5. The chain of infection requires which of the following elements?
A) Pathogen, reservoir, portal of exit
B) Mode of transmission, portal of entry
C) Susceptible host
D) All of the above
Answer: D
The chain of infection requires all six elements: pathogen (infectious agent), reservoir, portal of exit, mode
of transmission, portal of entry, and susceptible host. Breaking any link prevents infection.
