Normal WBC count
5,000-10,000
A WBC count greater than 10,000 means
leukocytosis
Inflammation or infection

Plasma is made of
water
sugar
protein
albumin
What medication is used to treat and prevent polycythemia?
Hydroxurea
What occurs in polycythemia?
Transport of RBC's slows down Viscosity increases Ruby red color High risk for DVT May have excess Ca+
What disease destroys RBC’s
Malaria and receiving the wrong Rh factor
Iron deficiency anemia
Result when the dietary intake of iron is inadequate for hgb synthesis
Most common cause of iron deficiency anemia in men and post menopausal women is
Bleeding (ulcers, gastritis, or GI tumors)
Most common cause of iron deficiency anemia in pre menopausal women is
menorrhagia and pregnancy with inadequate iron supplementation
S/S of anemia
Fatigue Malaise Pallor Weakness Dyspnea Tachycardia Dizziness Orthopnea
A person with iron deficiency anemia may have what kind of tongue?
Smooth, sore and red
How to take oral iron supplements
Increase vitamin C intake
Take on empty stomach
Antacids/dairy products should be avoided
Drink liquid solutions thru straw
S/E of iron supplements
Constipation
Cramping
N/V
Dark green/black stools
What is aplastic anemia?
Bone marrow is replaced by fat. Most cases are idiopathic
What is the treatment for aplastic anemia?
Bone marrow transplant
S/S of aplastic anemia
Fatigue Pallor Purpura Dyspnea Weakness
Aplastic anemia can be manged with immunosuppressive therapy commonly using
Cyclosporine
Antihemocyte globulin (ATG)
Removes the immunologic function that prolongs anemia and allows bone marrow to recover
Megaloblastic anemia is caused by
Deficiencies if vitamin B12 and folic acid
Nursing interventions for aplastic anemia
Observe for tissue hypoxia/bleeding
Good oral hygiene
No IM or SC injections
Neurologic manifestations occur in which kind of anemia
Vitamin B12 deficiency
S/S of folic acid and vitamin b 12 deficiency anemia
Extremely pale
Paresthesia in extremities
Difficulty maintaining balance
Proprioception
What is the classic method of determining the cause of vitamin B12 deficiency
Schilling test
What is the Schilling test?
Oral dose of radioactive vitamin B12, followed by nonradioactive vit B12. If no radioactive is present in urine, the cause is GI malabsorption. If the radioactive is present in urine the cause is not ilieal disease or pernicious anemia
How is folic acid deficiency treated
Increase folic acid intake 1mg daily
Folic acid is administered IM only to people with
Malabsorption problems
Absence of intrinsic factor is treated by
Monthly IM injection of vitamin B12 for life
What can cause/trigger a sickle cell crisis?
Cold Dehydration Fatigue Menstruation ETOH Acidosis
Sickle cell is associated with
Tacycardia
Cardiac murmurs
Cardiomegaly
Patients with sickle cell anemia are susceptible to
infection pneumonia osteomyelitis leg ulcers priaprism
