Decreased RBC/renal disease/bone marrow
Rbc distruction - sickle cell anemia
126
Increased risk for anemia:
iron deficiency from poor nutrition
menorrhagia (heavy period bleeding) from menstrual,
sickle cell anemia,
trauma from excessive bleeding,
lack of erythropoietin from renal disease,
immunosuppression- from leukemia or lymphoma and medication therapy that depresses bone marrow activity.
127
S/s of anemia
The quicker the onset the more serious the condition.
Slowly becoming anemic may adapt to low hemoglobin levels:
common symptoms fatigue, weakness, skin pallor, tachycardia, shortness of breath. – severe may need to consider cardiovascular implications- heart pump faster in attempt to make up for low oxygen. Most common found in active adults, who will show a sign of anemia.
128
Tests for anemia
```
➢ Tests:
hemoglobin,
hematocrit,
RBC indices
, reticulocyte count,
iron studies,
Mcv- size of RBCs
serum vitamin B12 are looked over.

```
131
: type of anemia that occurs hemolysis outside RBC
o Genetic, Burns, radiation, drugs, toxins, autoimmune disease, transfusion reactions and bacterial infections can all cause.
o Enlarged spleen from removing damages RBCs.

Vitamin B12 Anemia:
141
- Deficiency of RBC’s due to impaired cellular regulation of bone marrow
And injury to pre-cursor cells
Due to bone marrow damage
Aplastic anemia
142
the body's immune system stops red blood cells from forming or causes them to clump together.
Treated with Immunosuppressant, steroids, splenectomy
Immunohemolytic anemia-
143
• Is an inherited disease whereby hemoglobin synthesis is missing either the alpha or beta chain of the hemoglobin molecule. Resulting in hemoglobin production being deficient and weak, hypochromic RBCs are formed and labeled target cells (bull eye appearance).
blood disorder involving less than normal amounts of an oxygen-carrying protein and fewer RBC than normal.
If children get this young, rarely live to adulthood, most common in Asians from China, Philippines and Thailand.
Thalassemia
144
What causes Thalassemia
Four genes causes alpha chain formation, with either one, two, three, or all four may cause the thalassemia conditions.
If all 4 are defective, the result is labeled alpha thalassemia major and is fatal, most commonly in utero.
145
Findings of Thalassemia
➢ Findings: mild to moderate anemia, bone marrow hyperplasia, bronze skin coloring-
more serious results in heart failure, liver and spleen dysfunction from increased RBC destruction, sever anemia, and fractures to long bones, ribs .
146
- form of anemia caused by genetic defect in RBC metabolism.
Contracted most commonly from medication that caused inflammatory disorder.
It is more common in males as it is on the X chromosome, usually Mediterranean or African people.
A condition causing red blood cells to break down in response to certain medications, infections, or other stressors.

Aka
Hereditary Spherocytosis
Also known as congenital hemolytic anemia and
151
Hereditary Spherocytosis findings
Findings:
starts in utero or early infancy exhibits anemia and hyperbilirubinema, higher severity so does jaundice appearance.
Gallstones develop young, and Aplastic crises are the most serious complication.
152
Hereditary Spherocytosis tests
➢ Test: family history, blood smear, no single test to identify.
153
➢ Hematological changes in older adults
➢ Decrease in blood volume with lower levels of plasma proteins
➢ Bone marrow produces fewer blood cells
➢ RBC, WBC counts lower
➢ Lymphocytes less reaction to antigens, lose immune function
➢ Hemoglobin levels fall after middle-age
154
FINDINGS IN HEMATOLOGIC DISORDERS NORMAL CHANGES IN THE OLDER ADULT SIGNIFICANCE/ALTERNATIVES
Nail Beds (for Capillary Refill) Pallor or cyanosis may indicate a hematologic disorder.
Thickened or discolored nails
Hair Distribution Thin or absent hair on the trunk or extremities may indicate poor PERFUSION to a particular area.
Progressive loss of body hair is a normal facet of aging. A relatively even pattern of hair loss that has occurred over an extended period is not significant.
Older adults also have decreased pubic hair as a result of age-related hormone changes.
Skin Moisture Skin dryness may indicate any of a number of hematologic disorders.
Skin dryness is a normal result of aging.
Skin moisture is not usually a reliable indicator of an underlying pathologic condition in the older adult.
Skin Color Skin color changes, especially pallor and jaundice, are associated with some hematologic disorders.
Pigment loss and skin yellowing are common changes associated with aging.
Pallor in an older adult may not be a reliable indicator of anemia. Laboratory testing is required.
Yellow-tinged skin in an older adult may not be a reliable indicator of increased serum bilirubin levels. Laboratory testing is required.
155
