Q

Disorders Associated with Erythrocytes: Name the description of the disorder below:

• Disorder characterized by RBC and hemoglobin and hematocrit levels below normal range
• Causes delivery of insufficient amounts of oxygen to tissues and cells

A

Anemia

17
Q

Average adult has approximately 6 liters (12 pints) of total blood volume
WHAT CONDITION CAN RESULT IF NOT ENOUGH BLOOD VOLUME?

A

HYPOVOLEMIC ANEMIA OR BLOOD LOSS ANEMIA

18
Q

Oliguria – (small amount of urine- less than 400 ml in 24 hours) AND IS ASSOCIATED IN THE SLIDES WITH WHAT DISORDER?

A

HYPOVOLEMIC ANEMIA/SHOCK

19
Q

THREE STAGES OF SHOCK:

WHAT STAGE OF SHOCK IS (also called compensated, or nonprogressive), when low blood flow (perfusion) is first detected.
S/S: confused with cool and clammy skin, decreased urinary output

A

STAGE 1

20
Q

THREE STAGES OF SHOCK
WHICH STAGE of shock is irreversible, the length of time that poor perfusion has existed begins to take a permanent toll on the body’s organs and tissues.
Patient becomes unconscious. The endpoint of This stage is patient death.

A

STAGE 3

21
Q

Where is the intrinsic factor located and what causes it to be absent?
A LACK OF INTRINSIC FACTOR CAUSES PERNICIOUS ANEMIA.
HAPPENS OFTEN AFTER GASTRIC SURGERY!

A

Intrinsic factor is a protein that helps your intestines absorb vitamin B12. It is made by cells in the stomach lining. Intrinsic factor binds to vitamin B12. VITAMIN B12 IS NEEDED FOR RBC TO FORM AND GROW.
PERNICIOUS ANEMIA IS CAUSED BY NOT GETTING ENOUGH VIT B12

22
Q

What is the medical management of sickle cell anemia?

A

Increase fluids (at least 8 glasses of fluid daily)
More fluid means lower viscosity/thickness
 Analgesics
Pain control is necessary during crisis – morphine and
hydromorphone (Dilaudid)

23
Q

What is a Blood disorder characterized by hyperplasia (overgrowth) of the bone marrow with Manifestations of Overproduction of circulating erythrocytes (erythrocytosis), granulocytes, and platelets?
It is characterized by an ^ of RBC in bloodstream, ^ hemoglobin and hyper viscosity, excess wbc and platelets.

A

Polycythemia (erythrocytosis)
There is an ^ of bleeding disorders

24
Q

MM and NI for Polycythemia (erythrocytosis)
+Reduction of blood viscosity
+Repeated Phlebotomy – removal of 500 to 2000 ml of blood until Hct level is maintained at 45-48%
What are the normal values for HCT and HGB?

A

HCT 35-45%
HGB 12-18

25
Q

Potentially fatal condition - Severe reduction in the number of granulocytes (basophils, eusinophils and neutrophils)
WBC extremely low (leukopenia) - less than 200/mm3
adverse medication or toxicity is primary cause Chemotherapy
Radiation
Neoplastic disease

A

Agranulocytosis

26
Q

Malignant disorder of the hematopoietic system
= EXCESSIVE number of ABNORMAL LEUKOCYTES accumulate in the bone marrow and lymph nodes
=Normal WBC in the bone marrow and replaced with abnormal numbers and forms rapidly dividing cells which then spread to circulation and infiltrate lymph nodes, spleen and other organs

A

Leukemia

27
Q

Condition in which the number of platelets is reduced below 150,000/mm3

Most common cause of increased destruction of platelets is Idiopathic thrombocytopenia purpura ITP– auto immune disease

A

THROMBOCYTOPENIA
MEDICATION: Corticosteroid therapy
Heartburn and Moon-face common with long term USE

28
Q

Hereditary coagulation disorder, characterized by absence of certain blood-clotting factors.
= Hemophilia A – more common – factor VIII is absent
= Hemophilia B (Christmas disease) much rare – factor IX is absent
= X-linked hereditary trait

A

HEMOPHILIA

S/S:
Internal and external bleeding
(petechiae and echymosis)
Hemarthrosis (bleeding into joint)

29
Q

Inherited bleeding disorder characterized by abnormally SLOW
coagulation of blood, episodes of GI bleeding, epistaxis and gingival bleeding.
• Similar to hemophilia; not limited to males

Desmopressin (DDAVP) – treatment of choice

A

VON WILLEBRAND’S DISEASE

Clinical manifestations/assessment
• Spontaneous episodes of • GI bleeding
• Epistaxis
• Gingival bleeding

Desmopressin (DDAVP) – treatment of choice

30
Q

-Grave coagulopathy resulting from overstimulation of clotting and anticlotting processes in response to disease or injury.
-Due to sepsis, blood transfusions, liver failure, cancer (especially leukemia), and even giving birth
-When clotting factors are “used up” or the body realizes
there are clots… there is excessive / abnormal bleeding
BLEEDING- CLOTTING- BLEEDING- CLOTTING….

A

Disseminated intravascular coagulation (DIC)
• There will be prolonged bleeding!!!

31
Q

COMPARE THESE AND GET THEM STRAIGHT!

Lymphangitis
ET= Inflammation of one or more lymphatic vessels
S/S= Fine red streaks from the affected area
M/M= Avoid injections and IVs on the affected side

A

Lymphedema
ET= Due to compression or obstruction of return of lymph, Accumulation of lymph in the soft tissue. For example> radical mastectomy
S/S= Massive edema and tightness of affected extremity and Pain
M/M= diuretics
NI= Elevate extremity affected

32
Q

Compare these two:

Hemophilia
• Etiology/pathophysiology
• A serious, lifelong bleeding disorder inherited as an X-linked recessive disorder

A

Idiopathic Thrombocytopenic Purpura
• Etiology/pathophysiology
• A marked decrease in the amount of circulating platelets with
resultant bleeding beneath the skin and Platelet count drops below 20,000.

33
Q

Aldosterone actions..

A

It’s a strong vasoconstrictor
Retain water and salt in kidneys which ^ body water = increase in BP
