body fluids Flashcards
. The primary purpose of serous fluid is to:
lubricate serous membrane
The membrane that lines the wall of cavity is the:
parietal
During normal production of serous fluid, the slight excess of fluid is:
absorbed by the lymphatic system
Production of serous fluid is controlled by:
capillary oncotic pressure
capillary hydrostatic pressure
capillary permeatibility
An increase in the amount of serous fluid is called a/an:
effusions
Pleural fluid is collected by:
thoracentesis
Caused by increased hydrostatic pressure
exudate
Caused by increased capillary permeability
transudate
Caused by decreased oncotic pressure
transudate
Caused by congestive heart failure
transudate
Malignancy related
exudate
Tuberculosis related
transudate
Endocarditis related
exudate
clear apearance
transudate
Fluid: serum protein and lactic dehydrogenase ratios are performed on serous fluids:
to classify transudates and exudates
Which of the following requires the most additional testing?
exudate
An Additional test performed on pleural fluid to classify the fluid as a transudate or
exudate is the:
fluid; cholesterol ratio
A milky-appearing pleural fluid indicates:
thoracic duct leakage and chronic inflammation
Which of the following best represents a hemothorax?
Blood HCT: 30 Fluid HCT: 20
All of the following are normal cells seen in pleural fluid, except:
mesothelioma cells
. A different observation of pleural fluid associated with tuberculosis is:
decreased mesothelial cells
All of the following are characteristics of malignant cells, except:
absence of nucleoli
A pleural fluid pH of 6.0 indicates:
esophageal rupture
. Plasma cells seen in pleural fluid indicate:
tubercolosis infection
A significant cell found in pericardial or pleural fluid that should be referred to
cytology is a:
mesothelioma cell
Another name for a peritoneal effusion is:
ascites
A test performed primarily on peritoneal lavage fluid is a/an:
rbc count
The recommended test for determining whether peritoneal fluid is a transudate or an
exudate is th
Serum ascites albumin gradient
Differentiation between bacterial peritonitis and cirrhosis is done by performing a/an:
absolute neutophil count
. Detection of the CA 125 tumor marker in peritoneal fluid indicates:
ovarian cancer
Chemical tests primarily performed on peritoneal fluid include all of the following,
except:
amylase
Cultures of peritoneal fluid are incubated:
aerobically and anaerobically
What is the primary cause of the normal increase in amniotic fluid as a pregnancy
progresses?
fetal urine
Which of the following is not a reason for decreased amounts of amniotic fluid?
fetal failure to begin swallowing
Why might a creatinine level be requested on an amniotic fluid
Differentiate amniotic fluid from maternal urine
Amniotic fluid specimens are placed in amber-colored tubes prior to sending them to
the laboratory to prevent the destruction of:
bilirubin
How are specimens for FLM testing delivered to and stored in the laboratory?
Delivered on ice and refrigerated
Why are amniotic specimens for cytogenetic analysis incubated at 37oC prior to
analysis?
To prolong fetal cell viability and integrity
A significant rise in the OD of amniotic fluid at 450 nm indicates the presence of which analyte?
Bilirubin
Plotting the amniotic fluid OD on a Liley graph represents the severity of hemolytic disease of the newborn. A value that is plotted in zone II indicates what condition of the fetus?
Moderately affected fetus that requires close monitoring
The presence of a fetal neural tube disorder may be detected by:
Increased maternal serum alpha- fetoprotein
