Answer Section
MULTIPLE CHOICE
1. ANSWER: 3
Patients acquire infection by contact with other patients, family members, and healthcare
equipment. But most infection among patients is spread through the hands of healthcare workers.
Hand washing interrupts the transmission and should be done before and after all contact with
,patients, regardless of the diagnosis. When the hands are soiled, healthcare staff should use
antibacterial soap with warm water to remove dirt and debris from the skin surface. When no
visible dirt is present, an alcohol-based rub should be applied and allowed to dry for 10 to 15
seconds.
2. ANSWER: 3
Patients are exposed to microbes by contact (direct contact, airborne, or otherwise) with other
patients, family members, and contaminated healthcare equipment. Some of these are pathogenic
(cause illness) and some are nonpathogenic (do not cause illness). But most microbes causing
infection among patients are spread by direct contact on the hands of healthcare workers.
3. ANSWER: 1
Scrupulous hand washing is the most important part of medical asepsis. Donning gloves,
applying sterile drapes before procedures, and wearing a protective gown may be needed to
ensure asepsis, but they are not the mostimportant aspect because microbes causing most
healthcare-related infections are transmitted by lack of or ineffective hand washing.
4. ANSWER: 4
Some people might harbor a pathogenic organism, such as the human immunodeficiency virus
within their body, and yet do not acquire the disease/infection. These individuals, called carriers,
have no outward sign of active disease, yet they can pass the infection to others. A pathogen is an
organism capable of causing disease. A fomite is a contaminated object that transfers a pathogen,
such as pens, stethoscopes, and contaminated needles. A vector is an organism that carries a
pathogen to a susceptible host through a portal for entry into the body. An example of a vector is
a mosquito or tick that bites or stings.
5. ANSWER: 2
The organisms responsible for measles and tuberculosis, as well as many fungal infections, are
spread through airborne transmission. Neisseria meningitidis, the organism that causes
meningitis, is spread through droplet transmission. Pathogens that cause diarrhea, such
as Clostridium difficile, are spread by direct contact. The common cold can be spread by indirect
contact or droplet transmission.
6. ANSWER: 1
Thrush in this patient is an example of an endogenous, nosocomial infection. This type of
infection arises from suppression of the patients normal flora as a result of some form of
treatment, such as antibiotics. Normal flora usually keep yeast from growing in the mouth. In
exogenous nosocomial infection, the pathogen arises from the healthcare environment. A latent
infection causes no symptoms for long periods. An example of a latent infection is human
immunodeficiency virus infection. A primary infection is the first infection that occurs in a
patient.
7. ANSWER: 3
The stage of decline occurs when the patients immune defenses, along with any medical
therapies (in this case antibiotics), are successfully reducing the number of pathogenic microbes.
As a result, the signs and symptoms of infection begin to fade. Incubation is the stage between
the invasion by the organism and the onset of symptoms. During the incubation stage, the patient
does not know he is infected and is capable of infecting others. The prodromal stage is
characterized by the first appearance of vague symptoms. Convalescence is characterized by
tissue repair and a return to heal as the organisms disappear.
8. ANSWER: 1
,To maintain sterile technique, the nurse should close the patients door and limit the number of
persons entering and exiting the room because air currents can carry dust and microorganisms.
Sterile gloves, not clean gloves, should be used to handle sterile equipment. Placing nonsterile
syringes on the sterile field contaminates the field. One foot, not 6 inches, is required between
people and the sterile field to prevent contamination.
9. ANSWER: 3
The classic signs of inflammation, a secondary defense against infection, are erythema (redness)
and localized heat. The secondary defenses phagocytosis (process by which white blood cells
engulf and destroy pathogens) and the complement cascade (process by which blood proteins
trigger the release of chemicals that attack the cell membranes of pathogens) do not produce
visible findings. Immunity is a tertiary defense that protects the body from future infection.
10. ANSWER: 2
The patient is most likely experiencing an allergic response to the antibiotic. IgE is the antibody
primarily responsible for this allergic response. The antibodies IgA, IgG, and IgM are not
involved in the allergic response. IgA antibodies protect the body from in fighting viral and
bacterial infections. IgG antibioties are the only type that cross the placenta in a pregnant women
to protect her unborn baby (fetus). IgM are the first antibodies made in response to infection.
11. ANSWER: 2
Intravenous administration of immunoglobulin G provides the patient with passive immunity.
Immunoglobulin G does not provide cell-mediated, humoral, or active immunity. Passive
immunity occurs when antibodies are transferred by antibodies from an immune host, such as
from a placenta to a fetus. Passive immunity is short-lived. Active immunity is longer lived and
comes from the host itself. Humoral immunity occurs by secreted antibodies binding to antigens.
Cell-mediated immunity does not involve antibodies but rather fight infection from macrophages
that kills pathogens.
12. ANSWER: 1
More than 200 viruses are known to cause the common cold. These viruses mutate too rapidly to
develop a vaccine. Although some researchers are focusing efforts on a vaccine for HIV
infection, others continue to research the common cold.
13. ANSWER: 2
Fever, a common defense against infection, increases water loss; therefore, additional fluid is
needed to supplement this loss. Acetaminophen and a tepid bath are not necessary for this low-
grade fever because fever is beneficial in fighting infection. Adequate rest, not necessarily
bedrest, is necessary with a fever.
14. ANSWER: 3
Nonpetroleum-based lotion is preferred because it prevents the absorption of latex proteins
through the skin, which can cause latex allergy. Both types of lotion prevent the skin from drying
and becoming chafed. Neither prevents microorganisms from adhering to the skin.
15. ANSWER: 3
In a surgical setting, hands should be washed for 2 to 6 minutes, depending on the type of soap
used.
16. ANSWER: 2
Patients who require airborne isolation are served meals on disposable dishes and trays. To
dispose of the tray, the nurse inside the room must wear protective garb and place the tray and its
, contents inside a special isolation bag that is held by a second healthcare worker at the patients
door. The items must be placed on the inside of the bag without touching the outside of the bag.
17. ANSWER: 2
APIC guidelines dictate that 3 to 5 mL of liquid soap is necessary for effective hand washing.
18. ANSWER: 4
The nurse should rub the antiseptic hand solution over all surfaces of the hands until the solution
dries, usually 10 to 15 seconds, to ensure effectiveness.
19. ANSWER: 2
Protective isolation is used to protect those patients who are unusually vulnerable to organisms
brought in by healthcare workers. Such patients include those with low white blood cell counts,
with burns, and undergoing chemotherapy. Some hospital units, such as neonatal intensive care
units and labor and delivery suites, also use forms of protective isolation.
20. ANSWER: 2
The gloves should be thrown away because the gloves are likely to be contaminated from an
outside source. The supplies do not have to be thrown away because they have not been
contaminated.
21. ANSWER: 2
The gloves are removed first because they are usually the most contaminated PPE and must be
removed to avoid contamination of clean areas of the other PPE during their removal. The gown
is removed second, then the mask or face shield, and finally, the hair covering.
22. ANSWER: 3
If a nurse becomes exposed to body fluid, she should first wash the area, tell another nurse she is
leaving the area, contact the infection control or employee health nurse immediately, and
complete an incident report. It is most important to remove the source of contamination (body
fluid) as soon as possible after exposure to help prevent the nurses from becoming infected. The
other activities can wait until that is done.
MULTIPLE RESPONSE
1. ANSWER: 3, 4
Standard precautions should be instituted with all clients whenever there is a possibility of
coming in contact with blood, body fluids (except sweat), excretions, secretions, mucous
membranes, and breaks in the skin (e.g., while inserting a peripheral IV). When interviewing a
client, if the disease is not spread by air or droplets, there is no likelihood of the nurses
encountering body fluids. If the disease is spread by air or droplets, then droplet or airborne
precautions would be needed in addition to standard precautions. If giving a complete bed bath
or performing oral hygiene, the nurse would need to use standard precautions (gloves); if merely
assisting a client to perform those ADLs, it is not necessary. No exposure to body fluids is likely
when helping a client to ambulate after surgery.
2. ANSWER: 1, 3, 4
Nutrition, hygiene, rest, exercise, stress reduction, and immunization protect the body against
infection. Illness, injury, medical treatment, infancy or old age, frequent public contact, and
various lifestyle factors can make the body more susceptible to infection.
3. ANSWER: 1, 3, 4
Hand washing requires at least 15 seconds of washing, which includes lathering all surfaces of
the hands and fingers to be effective. The fingers should be held lower than the wrists.
4. ANSWER: 1, 3, 4
