Lab Values Flashcards
What are labs utilized for
screening
diagnosis
monitoring
what factors can affect labs
age
gender
race
pregnancy
food ingestion
What are we examining in a CBC
RBC
Hbg
Hct
MCV
MCH
MCHC
RDW
Platelet
WBC
What is being counted in the RBC
of circulating RBCs in 1mm3 of blood
What do RBCs carry
o2
what do RBCs contain
Hemoglobin molecules
what can a high WBC indicate
congenital heart disease
severe COPD
polyctheremia vera
leukemia
hodgkin disease
What is measured when we look at hemiglobin
measurement of total amnt of Hbg in the blood
What could high Hbg indicate
erthoryocytosis
congenital heart failure
severe COPD
polycythermia vera
severe dehydration
What could low Hbg indicate
anemia
hemoglobinopathy
cirrhosis
hemolytic anemia
hemorrhage
dietary defiency
bone marrow failure
prosthectic valves
renal disease
normal pregnancy
rheumatoid arthiritis
lymphoma
leukiemia
Hodgkin disease
What is an indirect measurement of RBC # & volume
Hematocrit
what is part of routine testing & anemia evaluation
hematocrit
what could high hematocrit indicate
erthrocytosis
congenital heart disease
severe COPD
polycythermia vera
severe dehydration
what could low hematocrit indicate
anemia
hemogloinopathy
cirrhosis
hemolytic anemia
hemorrhage
dietary deficiency
bone marrow failure
prosthetic valves
renal disease
normal pregnancy
rheumatodi arthritis
lymphoma
leukemia
hodgkin disease
What is anemia
a decrease in # of RBCs (erythrocytes)
what can contribute to anemia
impaired RBC production
blood loss
RBC destruction
Combo of all 3
Can we give lovonox or enaxoprin to a pt with a platelet count of 100,000 or lower
no
Why are we not able to take lovonox or enaxoprin w/ a platelet count of 100,000 or lower
because the pt is not able to clot blood very well and we do not want to slow down the clotting process
what could high platelet count indicate (thrombocytosis)
malignant disorders, polycythemia, post splenectomy syndromes, rheumatoid arthiritis, iron deficiency anemia
What if the thrombocyte level is above 1 million
pt is @ risk of clotting
what if thrombocyte level is greater than 600,000
potential for issues
what could low thrombocyte count indicate
hypersplenism, hemmorrhage, immune thrombocytopenia, leukemia, thrombic thrombocytopenia, Graves disease, inherited disorder, DIC, pernicious, anemia, hemolytic anemia, cancer, chemotherapy, infection
what do thrombocyte counts below 50,000 indicate
significant bleeding
