important Flashcards
THROMBO-CYTOPENIA
reduction of platelets below 150 × 10 /L or 150 000 per mcL.
The causes of platelet disorders
impaired production, increased destruction, or abnormal distribution.
Platelet disorders can be inherited, but the vast majority of them are acquired.
The causes of acquired disorders include autoimmune diseases, increased platelet consumption, splenomegaly, marrow suppression, bone marrow failure, and the ingestion of certain foods, herbs, and drugs.
immune thrombo-cytopenic purpura (ITP) and therapy
The most common acquired thrombo-cytopenia is a syndrome of abnormal destruction of circulating platelets
Multiple therapies are used to manage the client with ITP, such as corticosteroids or splenectomy.
heparin use
ife-threatening condition called heparin-induced thrombo- cytopenia (HIT) or heparin-induced thrombo-cytopenia and thrombosis syndrome (HITTS).
Heparin must be discontinued when HITTS is first recognized,
which is usually if the patient’s platelet count has fallen 50% or more from its baseline
or if a thrombus forms while the client is on heparin therapy.
thrombosis-cytopenia goals
(1) have no gross or occult bleeding,
(2) maintain vascular integrity, and
(3) manage home care to prevent any complications related to an increased risk for bleeding.
nursing diagnoses for thrombocytopenia
Potential for bleeding as evidenced by inherent coagulopathy
* Potential for impaired oral mucous membrane integrity as evidenced by decrease in platelets and treatment regimen
* Inadequate knowledge as a result of insufficient information,insufficient knowledge of resources
clinical manifestations
Could be asymptomatic
Bleeding: mucosal or cutaneous, gingival bleeding
when platelet count is low, rbc can leak out of the blood vessels and into skin causing petechiae and a lot of them results in a bruise called purpura
Labs – cbc including platelet count
Bone marrow aspiration and biopsy
diagnostic
bone marrow aspiration and biopsy
2) cbc including platelet count
3) specific laboratory studies
therapy for immune thrombocytopenia purpura
Corticosteroids
* Intravenous immunoglobulin
(IVIG)
Splenectomy
* Platelet transfusions
(if life-threatening)
* Immunosuppressives
(e.g., rituximab [Rituxan],
cyclosporine)
Hemophilia
an X-linked recessive genetic disorder caused by defective or deficient
coagulation factor.
The two major forms of hemophilia, which can occur in mild to severe forms, are hemophilia A (classic hemophilia, factor VIII deficiency) and hemophilia B (Christmas disease, factor IX deficiency).
Von Willebrand disease
is a related disorder involving a deficiency of the von Willebrand coagulation protein.
hemophilia therapy
Replacement of deficient clotting factors is the primary means of supporting a patient with hemophilia.
In addition to treating acute crises, replacement therapy may be given before surgery and before dental care as a prophylactic measure.
Home management
is a primary consideration for the client with hemophilia because the disease follows a progressive, chronic course.
patient teaching for haemophilia
The patient with hemophilia must be taught to recognize disease-related problems and to learn which problems can be resolved at home and which require hospitalization.
DISSEMINATED INTRAVASCULAR COAGULATION DIC
is a serious bleeding and thrombotic
disorder results from abnormally initiated and accelerated clotting which can lead to uncontrollable hemorrhage
