DIC Flashcards
With minor vessel injury, primary hemostasis is achieved:
usually within seconds
In vivo, the primary activator of the coagulation cascade occurs via the
extrinsic pathway
Common to both the intrinsic and the extrinsic pathway is:
factor X
The nurse is caring for a patient with cirrhosis of the liver. The nurse notes fresh blood starting to ooze from the patients rectum and intravenous site. The nurse contacts the provider expecting an order for:
vitamin K injections
A patient with a history of pulmonary embolism is being worked up for a potential coagulopathy that increases the risk for clotting. The nurse understands that the provider may order a test for
protein C deficiency
The nurse understands that when clots breakdown in a patient with a hematological disorder, that which value will increase?
fibrin split products
The patient is admitted with anemia caused by blood loss and thrombocytopenia. His platelet count is 22,000/microliter. The patient is scheduled for a transfusion of RBCs and a transfusion of platelets. The nurse should:
give the platelets before the RBCs.
The patient has a platelet count of 9,000/microliter. The nurse realizes that:
the patient is at great risk for fatal hemorrhage
The patients platelet count is 35,000/microliter. The provider orders the administration of 10 units of single-donor platelets. After transfusion, the nurse can expect the patients platelet count to be:
between 85,000/microliter and 135,000/microliter
The patient is admitted with anemia and active bleeding. The nurse suspects intravascular disseminated coagulation (DIC). Definitive diagnosis of DIC is made by evidence of:
an increased D-dimer level.
In caring for the patient who has a coagulopathy, the nurse should: (Select all that apply.)
a. assess fluids for occult blood.
c. limit invasive procedures.
e. weigh dressings to assess blood loss.
Accepted treatments for disseminated intravascular coagulation (DIC) may require: (Select all that apply.)
a. platelet infusions.
b. administration of fresh frozen plasma.
c. cryoprecipitate.
d. packed RBCs.
