What lab testing results are indicative of DIC?
Decrease levels: -Fibrogen

The nurse is reviewing the laboratory test results of a child diag-
nosed with disseminated intravascular coagulation (DIC). Which
of the following would the nurse interpret as indicative of this
disorder?

The nurse is caring for a postpartum patient admitted to the
intensive care unit with a diagnosis of disseminated intravascular
coagulation (DIC). What is the drug of choice to treat this problem?
A.) Heparin
A. Heparin
B. Urokinase
C. Aspirin
D. Warfarin
In the ICU, a postsurgical client has developed sepsis and is being
treated with multiple medications. During the mid-morning as-
sessment, which finding leads the nurse to suspect the client may
be developing a complication called disseminated intravascular
coagulation (DIC)? Select all that apply.
D) Hemorrhage from the surgical site requiring deep pressure
A) Headaches associated with light sensitivity
dressings
B) Oozing from all previous puncture and intravenous sites
C) Decreased O2 saturation and diminished breath sounds in
lower lobes
D) Hemorrhage from the surgical site requiring deep pressure
dressings
E) Urine from the Foley catheter is bloody
A healthy, primiparous (first-time) mother delivered a healthy in-
fant several hours ago, but the mother has experienced postpar-
tum hemorrhage. Which of the following disorders is most likely to
underlie the client's excessive bleeding after delivery?
A) Disseminated intravascular coagulation
A) Disseminated intravascular coagulation
B) Hemophilia A
C) Von Willebrand disease
D) Thrombotic thrombocytopenic purpura (TTP)
-It prevents the clotting phase from being completed which inhibits
the breakdown of fibrinogen.
What is the concept behind heparin for PT with DIC?
- It also helps avoid hemorrhage by preventing the body from
depleting entire stage of coagulation factors.
-Directly related to bleeding problems such as:
What are some acute clinical manifestations of DIC? Petechia, Purpura, oozing from puncture sites or severe hemor-
rhaging.
-Tissue factors released from necrotic place/fetal tissue or amni-
How does DIC happen in postpartum hemorrhaging?
otic fluid my enter the circulation, inciting DIC.
What is a common cause of DIC? -Sepsis
