Anemia Flashcards
CRITICAL THINKING: 1. Be familiar c components of labs & diagnostic studies 2. Track values over time 3. Prioritize significant manifestations for further investigation 4. Distinguish normal from abnormal and benign from serious 5. Evaluate the whole pt
1
Q
What is Anemia?
A
- Decrease in Total Body RBC(erythrocyte) Volume
- Decreased Hgb Protein
- Decreased Hct & RBC count
- Most Common Blood Disorder
2
Q
Anemia Compensatory Mechanism:
Acute Blood Loss Anemia
A
- @ the detection of Hypoxia the body tries to get back to homeostasis by compensation.
- Circulating blood volume decreases which leads to decreased Cardiac Output
- Comp Mech activates resulting in:
Increased HR
Increased BP
Increased RR
Peripheral vessels & 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
Risk Factors: Anemia
A
Poor Health Maintenance: 1. Smoking 2. Excessive Alcohol Intake 3. Poor Dietary Pattern 4. Sedentary Lifestyle Alterations in Hematologic System: 1. Medications 2. Diseases 3. Behavioral Patterns 4. Family Hx 5. Surgical Interventions
4
Q
Transfusion Therapy
A
- Severe reactions occur during 1st 50 mL
- Stay c pt for 1st 15–30 minutes
- Whole Blood
- Packed RBC’s (PRBC’s)
- Platelets
- Fresh Frozen Plasma (FFP)
5
Q
Whole Blood & PRBC’s Transfusion
A
- Infuse c Normal Saline Only
- Complete Transfusion in 4 Hours
- Never add Drugs to blood
6
Q
Platelet Transfusion
A
- Client c Platelet count less than 20,000 or 80,000 is actively bleeding
- Filter can be used
- Infuse in 15–30 Minutes
7
Q
Fresh Frozen Plasma Transfusion
A
- INDICATION:
a. Clotting Factor Deficiency
b. Liver Disease
c. DIC
d. PT or PTT greater than 1.5 times normal - Infuse over 20–30 minutes
- Use filter for infusion
8
Q
Physical Assessment:
A
SUBJECTIVE DATA: 1. Presenting symptoms 2. Chief complaint 3. Family Hx OBJECTIVE DATA: 1. Physical exam (H-->T) 2. Vital Signs 3. Labs
9
Q
How to document chief complaint
A
In pt’s own words:
- Elimination pattern
- Activity–exercise pattern
- Sleep–rest pattern
- Cognitive–perceptual pattern
10
Q
What type of presenting symptoms of anemia?
A
- FATIGUE & weakness #1 common
- SOB also common
- Increasing illness
- Fevers & decreased WBC
- Unusual bleeding
a. Problems c platelet
b. Thrombocytes
c. Clotting Mechanism - Pallor
- Tachycardia & Tachypnea c Dyspnea
- Vertigo/Dizziness especially when standing
- Headache & Irritability
- Decreased Hgb, Hct, & RBC
11
Q
Labs & Diagnostics
A
- CBC
a. Hgb b. Hct c. Total RBC’s d. Reticulocyte count - Serum Vitamin B12 & Folate Levels
- Iron
- Hgb Electrophoresis Analysis
- Schilling Test
- Bone Marrow Aspiration
12
Q
Severity of Anemia
A
Based on Hgb
1. Normal = 12–16 g/dL
- Mild Anemia = 10–12
- Moderate Anemia = 7–11
- Severe Anemia = HtC <25%
13
Q
Care Interventions for Anemia
A
- Resolve Hypoxemia
- Replace Blood Volume
- Determine Underlying Cause
RESOLVE–>REPLACE–>DETERMINE
14
Q
Nursing Role for Anemia pt
A
- PREVENT complications secondary to decreased O2 carrying capacity.
- ASSESS/Identify underlying causes
- MONITOR: Symptoms, Lab changes, Physical changes
- INITIATE Interventions unique to Dx
15
Q
Patient Teaching & DC Priorities for pt c Anemia
A
- Dietary restrictions
- Fatigue management
- Medications
- Disease prevention
- Safety
- Reportable clinical manifestations
