Question | Answer |
Liver is the major site of storage for | iron, glycogen and lipids |
liver plays an important role in getting rid of waste products such as | bilirubin ammonia and urea |
Indicators of metabolic function decreased albumin functions are due to | decreased synthesis by the liver |
ascites is due to | decreased oncotic pressure |
increased prothrombin time is | increased clotting time |
most clotting factors are produced by | the liver |
ammonia is very toxic to the | brain |
bilirubin is derived from the breakdown of | hemoglobin |
a majority of enzymes are | intracellular |
when tissue damage occurs enzymes are released | into the plasma |
the most sensitive tests for the liver are | enzyme tests |
hemoglobin in RBCs forms | heme + iron + protein |
heme is converted to | unconjugated (indirect) bilirubin |
unconjugated (indirect) bilirubin is ____ and will attach to ________ to be transported to the __________ | insoluble albumin liver |
unconjugated bilirubin can not be excreted in the _______ in this form | urine |
bilirubin is transported to the liver and combines with ______ by the enzyme to form | glucuronic acid glucuronyl transerase conjugated (direct) bilirubin |
conjugated (direct) bilirubin is water _________ | soluble |
the majority of conjugated bilirubin produced in the liver is transported into the | bile ducts and intestinal tract |
in the GI tract bacterial enzymes convert the conjugated bilirubin to | uroilinogen |
urobilinogen forms ______ which gives the feces its brown color | urobilin |
Total bilirubin reference range | 1.0mg/dL or less |
urine bilirubin reference range should be | negative |
signs and symptoms of jaundice serum bilirubin is | greater than 3mg/dL |
signs and symptoms of jaundice serum appearance is | icteric |
prehepatic jaundice is also known as | hemolytic jaundice |
hepatic jaundice involves the _______ conversion of unconjugated bilirubin to conjugated bilirubin by the liver | decreased |
posthepatic jaundice is also known as | obstructive jaundice |
in pre and post hepatic jaundice the function of the liver | is not impaired |
In prehepatic jaundice an increased destruction of _______ exceeds the ability of the liver to conjugate and excrete bilirubin. | RBCs |
Causes of prehepatic jaundice are | hemolytic anemias transfusion reactions hemolytic disease of newborn |
lab findings for prehepatic jaundice include ______ total bilirubin ______ indirect or unconjugated bilirubin ______urine bilirubin ______fecal urobilinogen ______retic count | increased: total bilirubin increased: indirect or unconjugated bilirubin negative: urine bilirubin increased: fecal urobilinogen increased: retic count |
Hemolytic Disease of the Newborn is usually due to the _____ incompatibility of the mother and child | Rh |
_____ levels of indirect bilirubin due to excessive breakdown of baby's RBCs | increased |
when baby's unconjugated bilirubin levels reach greater than ___________ bilirubin is either unbound or loosely bound to albumin | 15-20mg/dL |
loosely bound of unbound unconjugated bilirubin has a high affinity for | brain and CNS tissue |
bilirubin deposited in the brain tissue causes irreversible brain damage called | kernicterus |
monitor baby's _____ as well as ______ levels very closely | albumin bilirubin |
hepatic jaundice is the failure to | conjugate bilirubin |
hepatic jaundice has defective transport | in or out of hepatocyte |
hepatic jaundice lab values _______ depending on disease process | vary |
hepatic retention jaundice is the defective transport of _______ into _________ | bilirubin hepatocyte |
hepatic retention jaundice Physiologic jaundice of newborn | baby's glucuronyl transferase system not fully developed, especially in premies |
hepatic retention jaundice Chronic liver disease | liver eventually loses its ability to conjugate |
Lab findings for Hepatic Retention Jaundice ____indirect bilirubin urine bilirubin ______ | increased negative |
