NURS 6202 Exam 2 Questions with Verified
Correct Answers
Microcytic anemia
-Low MCV
-Small RBCs
-Often associated with iron-deficiency or Thalessaemia
Normocytic anemia
-MCV 80-100 (WNL)
-acute blood loss
-anemia of chronic dx
- Aplastic Anemia
macrocytic anemia
• High MCV
• Large, fragile RBCs
• Often associated with folate and/or B-12 deficiency; pernicious anemia
Anemia
A deficiency in the number of erythrocytes (RBC), quantity of Hgb, and/or the volume of
packed RBC (HCT)
normal hemoglobin levels
Male: 14-17.3 g/dL
Female: 11.7-15.5 g/dL
Normal hematocrit levels
,Male: 45%-52%
Female: 36-48%
Iron Deficiency Anemia
- Most common form of anemia
- Low iron levels
- Causes: poor intake, absorption problem, blood loss
- tx: diet, supplementation
iron deficiency anemia Sx
"LOW IRON"
Lethargic
Overexert easily
White face (pale)
Inflammation of tongue
Reduced Hgb Lvls
Observe changes in RBC
Nail changes (spoon shaped)
Iron supplementation education
- take on an empty stomach 1 hr before meals
- take with vitamin C (OJ)
- Stool will be dark black
- Side effect: constipation
- If liquid: mix with a drink and drink with a straw
Thalassemia
, -Inherited defect in the ability to produce hemoglobin, usually seen in persons of
Mediterranean background.
- Fragile, hypochromic, microcytic RBCs
Thalassemia symptoms
- fatigue, weakness, pale or yellowish skin
- facial bone deformities, slow growth
- abd swelling, dark urine
Thalassemia treatment
Blood transfusions
Iron Chelation therapy—for iron overload
Splenectomy may be required
Moderate cases survive into their 30s
Sickle Cell Anemia
-a genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells
assuming an abnormal sickle shape
- RBC have decreased life span (~20 days)
Factors that can lead to sickle cell crisis
"SICKLE"
Significant blood loss
Illness
Climbing or flying to high altitudes
Keeping continued stress
