The nurse is assessing a female patient of child-bearing age for symptoms of iron-deficiency anemia, including
• Iron-deficiency anemia can cause pallor, dyspnea, tachycardia, malaise, fatigue, and palpitations. Most symptoms are a direct result of compensation for the lack of oxygen-carrying capabilities. Women of child-bearing age are at higher risk for iron-deficiency anemia, especially if they experience menorrhagia (heavy menstrual bleeding).
• Incorrect: Weight loss and night sweats are not symptoms of iron-deficiency anemia.
• Incorrect: Rash and pruritus may be present in hemolytic anemia.
• Iron deficiency anemia is a microcytic anemia often caused by chronic blood loss from minor gastrointestinal bleeding or colon cancer. Over time, the demands for iron exceed intake. Even blood loss of 10–20 milliliters of red cells per day is more iron than a person can absorb in the diet. Manifestations of iron-deficiency anemia include fatigue, pallor, fissures at the corners of the mouth, spooning of fingernails, and reduced exercise tolerance. Anemia is defined as HGB < 13 g/dL for men and <12 g/dL for women.
• Pernicious anemia is a macrocytic anemia that results when vitamin B12 cannot be absorbed in the distal small intestine because there is a lack of the required intrinsic factor (which is normally produced by parietal cells in the stomach) needed for the absorption to occur. Pernicious anemia may result after surgical removal of parts of the stomach or from chronic gastritis causing decreased secretion of intrinsic factor. Autoimmune conditions may also produce antibodies against gastric parietal cells. When the production of intrinsic factor declines gradually, symptoms may progress over 20+ years, from mild GI effects and mood swings to weakness and fatigue, paresthesias of feet and fingers, and even cognitive effects and memory deficits, as well as, difficulty walking. In later stages, these patients may have a beefy, red tongue and an enlarged liver that can lead to right-sided heart failure. The HGB can be 7–8 g/dL. Treatment requires monthly B12 injections for life.
• Folate (folic acid) deficiency is another macrocytic anemia. Folate deficiency is dangerous for unborn infants because folic acid prevents neural tube defects. Pregnant women are recommended to have at least 400 ug/day. Folate is absorbed in the small intestine and stored in the liver. Alcoholism or a diet low in vegetables can lead to folate deficiency. Patients with folate deficiency may develop stomatitis and ulcerations on the tongue. They may have dysphagia, flatulence, and watery diarrhea.
• Thalassemia major, or Cooley's anemia, is a disorder caused by defects in both
• Aplastic anemia is a normocytic anemia resulting from a decline in blood cell production related to bone marrow depression. (Pancytopenia is often seen with this type of anemia, resulting in the decline of all three types of blood cells.) RBC production declines gradually then WBCs or PLTs, so this anemia appears with a chronic pattern. Aplastic anemia can be either hereditary or acquired after birth. If the onset is sudden, symptoms include hypoxia, pallor, weakness, fever, and dyspnea. The slower onset produces progressive weakness, infections, low-grade fever, cellulitis in the neck, nosebleeds, or waxy and pale skin tones. Aplastic anemia can cause an extremely low HGB of 7 g/dL.
