The nurse works with a female client who recently developed an infection of
Staphylococcus aureus while in the hospital. In this case, S. aureus is which component
in the chain of infection?
A)Host
B)Environmental reservoir
C)Agent
D)Portal
Ans: C
Feedback: The agent, or the microbe that causes the disease, is the "what" of the
epidemiologic triangle. The host, or the organism that is harboring the infectious agent,
is the "who" of the triangle. The environment, which includes those external factors that
cause or allow disease transmission, is the "where" of the triangle. Other necessary
elements include a portal of exit from the host, environmental reservoirs, transmission,
and a portal of entry to a new host.
,Several levels of public health surveillance are necessary to protect the nation's health.
At what level are healthcare providers and health facilities required to report certain
infectious diseases?
A) Local
B) State
C) Federal
D) International
Ans: B
Feedback: Local reporting mechanisms are community specific. At the state level,
healthcare providers and health facilities are required to report certain infectious
diseases to state health departments. At the federal level, the Department of Health and
Human Services (DHHS) is the US public health infrastructure that develops policies to
protect the nation's health. The Centers for Disease Control and Prevention (CDC) also
is a partner with the World Health Organization (WHO) through the Global Outbreak
Alert and Response Network and the WHO Surveillance and Response system, which
provide international epidemic alerts and responses.
A client with tuberculosis sneezes in the waiting room and infects several other clients
who are sitting on the other side of the room. Which mechanism of transmission is
involved in this case?
A) airborne
B) droplet
C) Direct Contact
D) Indirect Contact
Ans: A
,Feedback: Airborne transmission occurs when microorganisms are carried in the air in
small particles, called droplet nuclei, at distances that exceed a few feet. Droplet
transmission theoretically is a form of contact transmission; the mechanism of transfer
of the pathogen to the host is quite distinct from either direct or indirect transmission.
Therefore, droplet transmission is considered a separate route of transmission. Droplets
are generated from the source person primarily during coughing, sneezing, or talking
and are propelled a short distance (<3 feet) through the air and deposited on the
conjunctivae, nasal mucosa, or mouth of another person. Direct contact occurs through
direct body surface-to-body surface contact and physical transfer of microorganisms
between a susceptible host and an infected or colonized person (or animal). Indirect
contact involves contact of a susceptible host with a contaminated intermediate
inanimate object, called a vehicle, such as a contaminated surgical instrument, needle,
toy, soiled clothing, or bed linen.
Vehicles also include food, water, and contaminated hands that are not washed. Indirect
contact also includes vector transmission.
Vectors are animal or insect carriers of infectious agents.
The student-nurse discusses transmission that involves contact of a susceptible host
with a vehicle. Based on the chain of infection links, which exemplifies a vehicle?
A)Animals
B) Insects
C) Reptiles
D) Water
Ans: D

intermediate inanimate object, called a vehicle, such as a contaminated surgical
instrument, needle, toy, soiled clothing, or bed linen. Vehicles also include food, water,

transmission. Vectors are animal or insect carriers of infectious agents.
Chloroquine-resistant malaria occurs in most of Africa, the Middle East, and Asia and
all of the South Pacific islands. This type of disease occurrence is known as:
A) Endemic
B) Epidemic
C) Pandemic
D) Outbreak
Ans: A
Feedback: an endemic disease, infection, or infectious agent occurs when it becomes
prevalent within a population or geographic area. An epidemic or outbreak refers to a
significant increase in an infection or infectious disease beyond the expected (endemic)
level in a certain population and/or geographic area. A pandemic is an epidemic that
generally spreads worldwide. The use of "outbreak" in this text is synonymous with
epidemic
A nurse is preparing to travel to Asia to assist with care of clients suffering from
chloroquine-resistant malaria. The type of disease occurrence is this nurse becoming
involved with if this disease also occurs in most of Africa, the Middle East, and the South
Pacific islands is an Endemic.
A 16-year-old client visits the community health clinic with concerns that she may have
a sexually transmitted infection (STI). She asks whether STIs are treatable. STIs that are
easily treated and curable include: (Select all that apply.)
