Q

what happens in patients with Multiple Myeloma?

A

Because of the large number of malignant plasma cells, an abnormal antibody called M-protein becomes the most prominent protein in the blood

Q

What is found in the urine of patients with MM and how is this dangerous?

A

Q

Signs and Symptoms of Multiple Myeloma?

A
  • -Hypercalcemia (dues to release of calcium due to breakdown of the bones)
  • -renal failure
  • -bone lesions
  • -Bone pain may be first symptoms
CRAB and A/G reverse: 
C - Calcium (hypercalcemia)
R - Renal Failure ( increase globulin)
A - Anemia
B - Bone Pain 
--A/G Reverse: Albumin decreases, Gloobulin increases

Q

Causes of Thrombocytopenia

A
  • -Hypersplenism-overactive spleen function that results from splenomegaly. Causes RBC to be destroyed, leukopenia, and thrombocytopenia.
  • -Autoimmune disease
  • -Hypothermia
  • -Viral or bacterial infections that cause disseminated intravascular coagulation (DIC)
  • -Heparin-Induced Thrombocytopenia (HIT)
  • -HIV
  • -Drugs
  • **Splenomegaly: enlarged spleen, can result in abnormalities w/ in the blood

Q

Petechia vs Purpura

A

Petechia: Small bleeds that are less than 3mm (small red dots)

Purpura: Reddish-purple bleeds that are greater than 3 mm (looks like bruises)

Q

Ecchymosis vs Epistaxis

A

Ecchymosis: Ecchymosis occurs when blood leaks from a broken capillary into surrounding tissue under the skin. This causes discoloration. Large, soft tissue bleeding

Epistaxis: aka nose bleeds; acute hemorrhage of the nostril, nasal cavity, or nasopharynx

Q

Thrombus vs. Embolus

A

Thrombus: A stationary clot that is attached to a vessel wall

Embolus: A thrombus that has detached from the vessel wall and is traveling through the bloodstream.

Q

What causes alterations in the process of coagulation?

A

Vitamin K deficiencies

17
Q

Why is Vitamin K important

A
  • It assists is not hemorrhaging or bleeding out
  • *Vitamin K is necessary for synthesis and regulation of prothrombin, the procoagulant factors (II, VII, IX, X), and anticoagulant factors proteins C and S**
18
Q

Hemostasis

A

stopping the flow of blood, keeping blood within the damaged vessels. One of the first steps in the wound healing process

19
Q

Vitamin K deficiency causes problems in what major organ and how does this affect the body?

A

Liver; Liver disease causes a broad range of hemostasis disorders:

  • -Defects in coagulation
  • -Fibrinolysis (prevents blood clots from growing and becoming problematic by breaking clots down)
  • -Platelet number and function
20
Q

Vasculitis

A

Inflammation of blood vessels

21
Q

Disseminated Intravascular Coagulation (DIC)

A

Complex, acquired disorder in which clotting and hemorrhage simultaneously occur

22
Q

Disseminated Intravascular Coagulation (DIC) is not a disease but a sign of an underlying disorder.
True/False

A

True

23
Q

Treatment for Disseminated Intravascular Coagulation (DIC)

A

Removing the stimulus that causes it
