17
Q

Can we give lovonox or enaxoprin to a pt with a platelet count of 100,000 or lower

A

no

18
Q

Why are we not able to take lovonox or enaxoprin w/ a platelet count of 100,000 or lower

A

because the pt is not able to clot blood very well and we do not want to slow down the clotting process

19
Q

what could high platelet count indicate (thrombocytosis)

A

malignant disorders, polycythemia, post splenectomy syndromes, rheumatoid arthiritis, iron deficiency anemia

20
Q

What if the thrombocyte level is above 1 million

A

pt is @ risk of clotting

21
Q

what if thrombocyte level is greater than 600,000

A

potential for issues

22
Q

what could low thrombocyte count indicate

A

hypersplenism, hemmorrhage, immune thrombocytopenia, leukemia, thrombic thrombocytopenia, Graves disease, inherited disorder, DIC, pernicious, anemia, hemolytic anemia, cancer, chemotherapy, infection

23
Q

what do thrombocyte counts below 50,000 indicate

A
