Unit 4 Chapter 33 Heparin Induced Thrombocytopenia

Question 1

What is the Antidote for Heparin

Answer 1

Protamine Sulfate

Question 2

What is another name for Heparin Drip?
A. Unfractionated heparin therapy.
B. Warfarin Assisted therapy
C. Anti-fibrinogen Therapy
D. Enoxaparin therapy

Answer 2

A. Unfractionated heparin therapy.

Question 3

Why would a Health Care a Provider prescribe Unfractionated heparin therapy(Heparin Drip)?

Answer 3

Some patients with a confirmed diagnosis of an existing blood clot are started on a regimen of IV UFH therapy.

The health care provider prescribes UFH to prevent further clo tting, which often develops in the presence of an existing clot, and to prevent enlargement of the existing clot.

Question 4

What should be assessed or monitored before initiating a Heparin Drip?

Answer 4

Before UFH administration;

a baseline prothrombin time (PT), activated partial thromboplastin time (APTT or aPTT),

international normalized ratio (INR), complete blood count (CBC) with platelet count, urinalysis, stool for occult blood, and creatinine level are required.

Notify the primary health care provider if the platelet count is below 100,000 to 120,000/mm3, depending on agency protocol.

Question 5

Which of the following Signs and Symptoms would warrant immediate attention during Unfractionated heparin therapy(UHF)?

A. normal abdominal sounds
B. Regurgitation
C. Ecchymosis
D. Jaundice

Answer 5

C. Ecchymosis

Monitor the patient for signs and symptoms of bleeding, including hematuria, frank or occult blood in the stool, ecchymosis, petechiae, altered mental status (indicating possible cranial bleeding), or pain (especially abdominal pain, which could indicate abdominal bleeding).

Assess patient for signs and symptoms of bleeding, which include hematuria, frank or occult blood in the stool, ecchymosis (bruising), petechiae, an altered level of consciousness, or pain.

If bleeding occurs, stop the anticoagulant immediately and call the health care provider or Rapid Response Team!

Question 6

Your patient has been on a heparin drip for more than a week. Which of the following complications do suspect to occur?
A. Heparin-Induced-Thrombocytopenia
B. Fat embolism
C. Air Embolism
D. Amniotic Embolism

Answer 6

A. Heparin-Induced-Thrombocytopenia

^IS A RARE CONDITION

result from the development of antiplatelet bodies within 6 to 14 days after the beginning of treatment. Platelets aggregate into “white clots” that can cause thrombosis, usually in the form of an acute arterial occlusion. **The health care provider discontinues heparin administration if severe heparin-induced thrombocytopenia (HIT) (platelet count <150,000), or “white clot syndrome,” occurs.

Question 7

What is another name for white clot syndrome?

Answer 7

Heparin Induced Syndrome

Question 8

Which of the following lab values is clinical finding of HIT?
a. platelet count 90,000
b. red blood cell 4.4mm
c. white blood cell 7,000
d creatnine 2.3

Answer 8

a. platelet count 90,000

The health care provider discontinues heparin administration if** severe heparin-induced thrombocytopenia (HIT) (platelet count <150,000), or “white clot syndrome,” occurs.** L

Question 9

What is the treatment for HIT, would they require anticoagulant therapy?
A. no
B. yes

Answer 9

Patients with HIT still need anticoagulation but with another
anticoagulation medication type like
-argatroban,
-lepirudinor,
-bivalirudin
(Angiomax).

Question 10

S/s of HIT

Answer 10

Symptoms of HIT include DVT’s and PE’s
