Blood Loss Anemia Flashcards
1
Q
Increased RBC Loss or Destruction Include Which Types of Anemia’s?
A
ACUTE OR CHRONIC BLOOD LOSS DUE TO: 1. Hemorrhage or Trauma 2. GI Bleed or Menstrual (Menorrhagia) INCREASED HEMOLYSIS: 1. Defective Hgb-- Sickle cell anemia
2
Q
c Blood Loss Anemia the Body Activates Compensatory Mechanisms, How does it work?
A
- @ detection of Hypoxia the body tries to get back to homeostasis by compensation.
- Circulating blood vol decreases–> leads to Cardiac Output drop
3. Comp Mech activates resulting in: Increased HR Increased BP Increased RR Peripheral vessels & vessels in Liver constrict which increases circulating volume
- Fluid shift Interstitial–>Vascular: Diluting blood & reducing blood viscosity
- Increased erythropoietin
- If hemorrhage persists Comp Mech is less effective & this increases risk for Shock & Circulatory Failure.

Q
What do labs & S/S look like during Compensation Activation?
A
- In early hemorrhage RBC’s are normal size & shape.
RBC count, Hgb, & Hct may look normal. - During fluid shift in the C.M. activation RBC, Hgb, & Hct drop
4
Q
What are some Diagnostic tests we can perform for Acute Blood Loss Anemia?
A
BP HR RR Urine Output Hct & Hgb (Hct does not accurately indicate blood loss)
5
Q
How do we know where the pt is bleeding in Acute Blood Loss Anemia?
A
The pt is bleeding somewhere in the body & it is a medical emergency. 1. Cranial vault 2. Pericardium or pleural space 3. Musculoskeletal compartments. a. Dark/coffee-like=lower bleed b. Light=upper bleed Bleeding into the GI tract is detected by: 1. Fecal occult blood in stool. a. Dark=Upper GI b. Light=Lower GI 2. Melena p longer bleeding 3. **Loss of RBC Volume**
6
Q
As an RN what are my duties for a pt with Acute Blood Loss Anemia?
A
MONITOR: 1. Hematologic labs 2. Urine Output 3. Cardiovascular Indicators 4. Integument changes(Bleeding specifically) 5. Pain Description TRANSFUSION: 1. Safely 2. Monitor fluid for overload & transfusion reaction
