A nurse removes a central line access device once the patient no longer requires
intravenous (IV) antibiotics. This action is an example of which strategy to prevent
antimicrobial resistance established by the Centers for Disease Control and Prevention
(CDC)?
A. Preventing transmission
B. Proper diagnosis
C. Preventing infection
D. Prudent antibiotic use - Answer -C. Preventing infection
The CDC's campaign to prevent the development of antimicrobial resistance in hospitals
focuses on four approaches: (1) prevent infection, (2) diagnose and treat infection
effectively, (3) use antimicrobials wisely, and (4) prevent transmission. Expeditious
removal of invasive devices, such as IV catheters, and restricting these devices to
essential use are examples of the CDC's strategy to prevent infection.
A first episode of OM that occurs within 3 months of life increases risk of recurrent OM.
Recurrent OM is three episodes within the past 3 months or four episodes within the
past year.
When an otoscopic examination is performed on an older adult patient, the tympanic
membrane may be:
A pinker than that of a younger adult.
B thinner than that of a younger adult.
C whiter than that of a younger adult.
D more mobile than that of a younger adult. - Answer -C
During otoscopy, the tympanic membrane of an older adult may be whiter in color than
that of a younger adult. The tympanic membrane may also appear more opaque and
dull. A yellow-amber eardrum color occurs with otitis media with effusion. A red color
occurs with acute otitis media. The tympanic membrane of an older adult may be thicker
compared with that of a younger adult. Hypomobility is an early sign of acute otitis
media.
The tympanic membrane of a child with acute otitis media would be:
A flat and slightly pulled in at the center.
B mobile and would flutter with the Valsalva maneuver.
C bulging with a distinct red color.
D shiny and translucent, with a pearly gray color. - Answer -C
, The tympanic membrane would be bulging and red with acute otitis media. A normal
tympanic membrane is flat and slightly pulled in at the center. A normal tympanic
membrane is mobile and flutters with the Valsalva maneuver. A normal tympanic
membrane is shiny and translucent, with a pearly gray color.
If the tympanic membrane has white dense areas, the examiner suspects:
A perforation from a ruptured membrane.
B scarring from recurrent ear infections.
C serous fluid from serous otitis media.
D a fungal infection. - Answer -B
White dense areas indicate scarring on the tympanic membrane from recurrent ear
infections. Dark oval areas indicate perforation from a ruptured tympanic membrane. Air
or fluid levels or air bubbles indicate serous fluid from serous otitis media. Black or white
dots indicate a fungal infection.
Which of the following instructions by the nurse is most appropriate for a client using
contact lenses who is diagnosed with bacterial conjunctivitis?
A. Discard all opened or used lens care products
B. Disinfect contact lenses by soaking in a cleaning solution for 48 hours
C. Put all cosmetics in a plastic bag for 1 week to kill any bacteria before resuing
D. Disinfect all lens care products with the prescribed antibiotic drops for 1 week after
infection - Answer -A. Discard all opened or used lens care products
The client who wears contact lenses and develops an eye infection should discard all
open or used lens care products and cosmetics to decrease the risk of reinfection from
contaminated products.
A patient has acquired an infection while in the hospital. The nurse identifies this type of
infection as what?
A. Superinfection
B. Suprainfection
C. Nosocomial infection
D. Resistant infection - Answer -C. Nosocomial infection
Nosocomial infections are acquired by patients while in the hospital. Superinfection and
suprainfection are terms used to describe the emergence of drug resistance.
Which are examples of the improper use of antibiotic therapy? (Select all that apply.)
A. Using surgical drainage as an adjunct to antibiotic therapy
B. Treating a viral infection
C. Basing treatment on sensitivity reports
