Anemia Flashcards
Why is anemia a disease of perfusion?
> > there aren’t enough RBC’s to carry adequate oxygen to tissue
-manifestation of something else
Anemai for men vs women
- Hg < 12 g/dL in women
- Hg < 13.5 g/dL in men (or 14 g/dL, per Iggy)
anemia a manifestation of
something else
anemia is temporary or permanent
either
labs for anemia
- CBC
- RBC’s (4-6 M cells/mcL)
- Hemoglobin (14-18g/dL/ 12-16 g/dL)
- Hematocrit (42-52%/ 37-47%)
- *Reticulocytes (0.5 – 2%)
- MCV (Mean Corpuscular Volume) (80-95)
normal HGB ranges
14-18g/dL/ 12-16 g/dL
normal hematocrit
42-52%/ 37-47%
normal reticulocytes
0.5 – 2%
Normal RBC
4-6 M cells/mcL
what is a reticulocyte
immature RBC
Why do I care about reticulocytes in relation to anemia
-Insight into whether the problem is production (low reticulocytes) or destruction (high- don’t have enough time to mature)
What does MCV stand for and what is the normal range
Mean Corpuscular Volume 80-95
Microcytic anemia is problem with
not having enough iron, RBC are too small
Macrocytic anemia is problem with
DNA synthesis, doesn’t have enough Folic Acid
–>cell continues to grow b/c DNA synthesis is slow
3 types of hemolytic anemia
- Sickle Cell Disease
- Glucose 6-Phosphate Dehydrogenase Deficiency Anemia
- Immunohemolytic Anemia
hemolytic anemia is characterized by
increased destruction of RBC
3 types of anemia that are a decreased production of RBC
- Normocytic Anemia
- ->Anemia of Chronic Disease - Macrocytic Anemias (DNA issue)
- ->Vitamin B12 deficiency anemia
- -> Folic acid deficiency anemia
- ->Aplastic Anemia - Microcytic Anemias (Hemoglobin issue)
- ->Iron Deficiency anemia ***
anemia risk factors
Blood Loss (Acute or Chronic) GI bleeding Hemorrhage Trauma Operative Menorrhagia Increased destruction of RBC’s Defective RBC’s Immune issue G6PD deficient Age Nutritional Issues GI Bleeding
Dietary intake issue or Malabsorption Iron deficient B12 deficient Folic acid deficient Bone Marrow Suppression Radiation Chemicals
anemia assessment
Fatigue Pallor Jaundice Dysrhythmias Tachycardia Dyspnea Shortness of breath Syncope Dizziness Headache Chest Pain
Nursing Interventions for anemia
Largely depend on the cause
Situationally, think:
Dyspnea Low SpO2- Elevate HOB , put oxygen on
Increased fatigue- rest periods
Intolerance of cold temperature- warm blanket
Orthostatic Hypotension- education about getting up slowly
Chest Pain - 12 lead EKG
Indication for Blood Transfusion=
When Hg < 7 g/dL OR your patient is anemic and symptomatic
causes of iron deficiency anemia
Poor diet
Blood loss
Poor GI absorption- common in elderly due to poor GI absorption
most common type of anemia?
iron deficiency
what do RBCs look like with iron anemia
Small RBC’s (microcytic/ low MCV)
iron deficiency anemia labs
Serum ferritin <10-12 ng/mL
Serum Iron < 60-80 mcg/dL
mouth fissures with what kind of anemia?
iron deficiency
*will not heal until anemia is better!
diet changes for iron deficiency anemia
Red meat & Liver Legumes Leafy greens Shellfish -Oral Supplements-constipation/stool dark color May cause GI distress
IV iron infusions = Only for ? and why?
severe iron deficiency, anaphylaxis risk!
Anemia of chronic disease common
elderly
severity of anemia of chronic disease?
mild to moderate
RBC appearance w/ anemia of chronic disease?
normocyctic
another name of anemia of chronic disease
anemia of inflammation
