ANSWERS A+ GRADED. Buy Quality Materials!
body fluid specimen types
blood, urine, CSF, genital specimens, synovial (joints), pleural (lungs), pericardial
(heart), and peritoneal (abdominal)
blood specimens
most often analyzed in the microbiology lab, usually for presence of bacteria
MLA role in collecting blood specimens
collecting, labelling, handling, processing, and storing specimens
urine specimens
used to test for common pathogens in the upper and lower urinary tract; frequently
submitted for culture and sensitivity testing
culture and sensitivity (C&S)
a request for a urine culture to find out which organisms are causing infection and to
find out if these organisms are sensitive to commonly used antibiotics
CSF specimens
pathogens often fastidious and affected by temperature; refrigeration will kill these
pathogens and result in a false-negative result
CSF analysis
requested STAT to help diagnose acute bacterial meningitis, an infection of the
meninges (membranes surrounding the brain and spinal column)
sputum
a pus that accumulates deep within the lungs of a patient with pneumonia, TB, or other
lower respiratory tract infection; produced only when disease is present
bronchial washings
saline washes done by a physician to obtain specimens from the lower bronchi
synovial fluid
from the joints
pleural fluid
the build-up of excess fluid between the layers of the pleura outside the lungs
pleura
thin membranes that line the lungs and the inside of the chest cavity
pericardial fluid
from around the heart
peritoneal fluid
from the abdominal cavity
genital specimens
collected on swabs for testing of bacterial vaginosis and yeast
NAAT (nucleic acid amplification test)
molecular technique used to detect a virus or a bacterium; cervical, urethral, and urine
specimens collected for chlamydia and gonorrhea testing
stool specimens
, used to identify parasites, pathogenic viruses, and pathogenic bacteria found in the GI
tract
diarrhea
most common symptom of GI tract infection
dysentery
diarrhea accompanied by cramping abdominal pain in varying degrees of severity
GI pathogens
salmonella, shigella, campylobacter, E.coli
bacteria causing diarrhea
vibrio, yersinia, aeromonas
ova and parasite (O&P) testing
done to determine whether a patient has an enteric parasite
wound specimens
obtained by aspirate using small needle and syringe; swabs typically contain normal
flora contamination
ways for tissue specimens to be processed:
sent to "atomic pathology" for documentation and analysis (fixed in 10% formalin); if
infection is suspected, sent to microbiology for C&S (not in formalin); sent to reference
lab for analysis
what causes superficial infections of the skin, hair, and nails
dermatophytes
MLA responsibilities in microbiology
collecting blood specimens and instructing patients on how to collect a urine specimen,
stool specimen, and sputum specimen
commensal bacteria
organisms that live in or on a human body that don't harm
specimen labelling
specimen source and/or specific site along with patient info
bacteremia
bacteria in the blood; blood infection
septicemia
microorganisms or their toxins in the blood
sepsis
overwhelming, unregulated response by the body to the blood infection that triggers
inflammatory responses that can lead to tissue damage, organ failure, and death;
leading cause of death by infection
symptoms of septicemia
fever, chills, malaise, low BP, changes in mental status
fever of unknown origin (FUO)
persistent fever with no obvious cause
blood culture collection: critical situations in need of rapid antibiotic
administration
2-3 cultures; 1 right after another; from different sites
blood culture collection: for FUO
2-3 cultures; 1 right after another; from different sites; if negative after 24-48hrs, 2 more
cultures from different sites
