NURS 316 Unit 5 questions with correct answers
A hospital client was swabbed on admission for an ARO and has just
been informed that MRSA is present in his groin. The client has a
normal core temp and WBC count. This client is experiencing:
A. Infection
B. Proliferation
C. Colonization
D. Inflammation Correct Answer-C. Colonization(14)
Which most accurately describes the characteristics of saprophytes?
They:
A. Derive energy from decaying organic matter
B. Are beneficial components of human microflora
C. Have RNA or DNA, but never both
D. Are capable of spore production Correct Answer-A. Derive energy
from decaying organic matter(14)
--- Saprophytes are free-living organisms obtaining their growth from
dead or decaying organic material in the environment. They are not
necessarily spore producing, and they are not typical components of
human microflora. Because most are bacterial or fungal, they contain
both RNA and DNA.
Which of the following are accurate characteristics of prions? Select all
that apply.
A. Disease usually progresses slowly.
B. The primary manifestation includes ataxia and dementia
,C. Prions are protease sensitive
D. Prions tent to aggregate into amyloid-plaques in the brain
E. Prions lack reproductive functions so are not very harmful to humans
Correct Answer-A. Disease usually progresses slowly.
B. The primary manifestation includes ataxia and dementia
D. Prions tent to aggregate into amyloid-plaques in the brain(14)
Which of the following outpatients are at great risk for developing
Treponema pallidum, the cause of syphilis? Select all that apply.
A. A homeless adolescent female performing oral sex for money
B. A male who frequents clubs catering to exotic dancers and sexual
favours.
C. A homosexual male couple who have had a monogamous relationship
for the past 20 years
D. An older adult female living in a condo who regularly has sex with 3-
4 men a week. Correct Answer-A. A homeless adolescent female
performing oral sex for money
B. A male who frequents clubs catering to exotic dancers and sexual
favours.
D. An older adult female living in a condo who regularly has sex with 3-
4 men a week. (14)
Chlamydiaceae have characteristics of both viruses and bacteria and are
a rather common sexually transmitted infectious organism. After entry
into the host, they transform into a reticulate body. The health care
provider should monitor which of the following clients for this possible
infection? Select all that apply.
,A. An adult male who raises a number of exotic birds in his home
B. A drug abuser looking to share needles/syringes
C. A newborn with a noticeable eye infection
D. A teenager who swims in the lake regularly. Correct Answer-A. An
adult male who raises a number of exotic birds in his home
B. A drug abuser looking to share needles/syringes
C. A newborn with a noticeable eye infection(14)
--- Chlamydiaceae are in the form of an elementary body when
infectious and outside of the host cell. Once an organism enters the cell,
it transforms into a large reticulate body. This undergoes active
replication into multiple elementary bodies, which are then shed into the
extracellular environment to initiate another infectious cycle.
Chlamydial diseases of humans include sexually transmitted genital
infections (Chlamydophilia trachomatis); ocular infections and
pneumonia of newborns (C. trachomatis); upper and lower resp tract
infections in peds and young adults (C. pneumoniae); and respiratory
disease acquired from infected birds (C. psittaci)
A client has been diagnosed with Coxiella burnetii infection. She asked
the nurse how she got this disease. The nurse's response is:
A. Probably while walking outside without your shoes on
B. While swimming in an unsanitary pond
C. Drinking contaminated milk
D. Eating undercooked fish Correct Answer-C. Drinking contaminated
milk(14)
--- In humans, Coxiella infection produces a disease called Q fever,
characterized by a nonspecific febrile illness often accompanied by
, headache, chills, arthralgias, and mild pneumonia. The organism
produces a highly resistant spore like stage that is transmitted to humans
when contaminated animal tissue is aerosolized (eg during meat
processing) or by ingestion of contaminated milk
A public health nurse notes an increase in regional throat cancer cases.
Upon epidemiological studies, many of the throat cancer clients also had
oral exposure to human papillomavirus (HPV), This exposure to HPV
would be considered by:
A. Deep penetration of open lesions
B. Direct contact with infected secretions
C. Ingestion of HPV through the GI tract
D. Accidental aspiration and inhalation of pathogens. Correct Answer-B.
Direct contact with infected secretions(14)
Which of the following would be considered an example of transmitting
an infection from person to person through shared inanimate objects
(fomites)?
A Malaria from mosquito bites
B. HIV from a contaminated IV drug user needle
C. Tuberculosis from inhalation of air after a cough
D. Typhoid from traveling to a third-world country. Correct Answer-B.
HIV from a contaminated IV drug user needle(14)
Although bacterial toxins vary in their activity and effects on host cells,
a small amount of gram-negative bacteria endotoxin:
