8 hours ago Hemoglobin is an iron-rich protein in red blood cells that carries oxygen. Hematocrit levels that are too low may be a sign of anemia. Hematocrit is a measure of how much space red blood cells take up in your blood. Mean corpuscular volume (MCV) levels that are higher or lower than normal may be a sign of anemia. >> Go To The Portal
The nurse understands that anemia has many possible etiologies. Which can cause anemia? Select all that apply. a. Diet low in vitamin D b. Reduction in the number of red blood cells
If you receive a diagnosis of anemia, your doctor might order other tests to determine the cause. Occasionally, it can be necessary to study a sample of your bone marrow to diagnose anemia. Our caring team of Mayo Clinic experts can help you with your anemia-related health concerns Start Here
Numbness and tingling may occur in anemia as a result of neurological involvement. 5. Fatigue is the number-one presenting symptom of anemia. The client diagnosed with iron-deficiency anemia is prescribed ferrous gluconate orally. Which should the nurse teach the client? 1. Take Imodium, an antidiarrheal, over-the-counter (OTC) for diarrhea. 2.
Folic acid and Vitamin B12 deficiency anemias are characterized by macrocytic red cells. Thalassemia and iron deficiency anemias are microcytic anemias. Sickle-cell anemia is characterized by sickle-shaped red cells; hence the name, sickle cell anemia.
CBC results in iron deficiency anemia include the following:Low mean corpuscular volume (MCV)Low mean corpuscular hemoglobin concentration (MCHC)Elevated platelet count (>450,000/µL) in many cases.Normal or elevated white blood cell count.
Serum iron and ferritin tests to check the amount of iron in your blood and body. A peripheral blood smear to see if your red blood cells are an abnormal shape. Hemoglobin electrophoresis to evaluate for abnormal hemoglobin, which is present in thalassemia and sickle cell disease.
The diagnostic criterion for anemia isFor men: Hemoglobin < 14 g/dL (140 g/L), hematocrit < 42% (< 0.42), or RBC < 4.5 million/mcL (< 4.5 × 10 12/L)For women: Hemoglobin < 12 g/dL (120 g/l), hematocrit < 37% (< 0.37), or RBC < 4 million/mcL (< 4 × 10 12/L)
A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including: Red blood cells, which carry oxygen.
The nurse should monitor the hemoglobin and hematocrit in all clients diagnosed with anemia. 2. Because decreased oxygenation levels to the brain can cause the client to become confused, a room where the client can be observed frequently—near the nurse's desk—is a safety issue. 3.
A patient with iron deficiency anemia is refusing to take the prescribed oral iron medication because the medication is causing nausea. The nurse should do which of the following ? Select all that apply
The decreased production of erythropoietin will result in a decreased hemoglobin and hematocrit. The patient will have normal MCV and RDW because the erythrocytes are normal in appearance. A nurse is caring for a patient with severe anemia. The patient is tachycardic and complains of dizziness and exertional dyspnea.
A patient with chronic anemia due to AIDS is prescribed erythropoietin therapy . Which other intervention does the nurse expect will be prescribed to make this therapy effective?
A patient with a low hemoglobin and hematocrit is admitted for diagnose of anemia. The patient exhibits generalized weakness, assessment reveals pale skin color, red sore smooth tongue and slight uncoordinated walk. Based on these findings, the nurse expects the health care provider to order:
When the hemoglobin level is low, the heart attempts to compensate by pumping faster and. harder in an effort to deliver more blood to hypoxic tissue. This increased cardiac workload can result in such symptoms as tachycardia, palpitations, dyspnea, dizziness, orthopnea, and exertional dyspnea.
An elderly patient has a hemoglobin of 9.8 mg/dl related to decreased iron intake. The nurse expects this patient to present
This type of anemia can be either acute or chronic. Increasing dietary intake of iron is the best way to treat iron deficiency anemia. Foods rich in iron include red meat, dark green leafy vegetables, dried beans, and iron-fortified cereals and breads. Increasing vitamin C intake helps the body absorb iron.
Rationale: Iron-deficiency anemia often occurs as a result of hemorrhage and chronic blood loss, for example, heavy menstrual bleeding, certain types of cancer (esophageal, colon, stomach), and ulcerative gastrointestinal problems such as peptic ulcer disease. Poor absorption of iron may be due to celiac disease, Crohn's disease, and the chronic use of medications such as H2 inhibitors, proton-pump inhibitors, antacids, aspirin, and NSAIDs. Gastrointestinal surgeries such as gastric bypass surgery and partial and total gastrectomy can lead to poor absorption of iron and IDA. In older adults with multiple comorbidities, anemia is frequently a cause for hospitalization and exacerbates many chronic conditions, such as congestive heart failure (CHF) and chronic kidney disease.
Because the body does not produce vitamin B12, it must be ingested through animal proteins, food fortified with this vitamin, or supplementation.
Rationale: Aplastic anemia, also called hypoplastic anemia, is a rare disease process that develops due to bone marrow depression or damage, and is often acquired secondary to infections, including hepatitis and human immunodeficiency virus. Blood work typically shows pancytopenia because of poor bone marrow function.
Pernicious anemia is related to vitamin B12 anemia. It is caused by the absence of a specific factor known as the intrinsic factor. Without the intrinsic factor, oral vitamin B12 cannot be effectively absorbed by the intestines, no matter how much of the vitamin is present.
Rationale: Susan's symptoms of confusion and disorientation can be caused by decreased oxygenation of the brain. Fewer mature red blood cells and hemoglobin are available to oxygenate the brain and the rest of the body.
With all types of anemia, patient education is important to ensure he or she understands the dietary sources to correct the deficiency. The patient must also be aware of the importance of any medications and supplements and the potential side effects of each. The nurse should instruct the patient to immediately report any clinical symptoms of anemia, such as fatigue, dizziness, and shortness of breath, to the healthcare provider.
a. Vitamin B12 and iron deficiency anemia
The most common body systems associated with blood loss are the gynecologic tract (GYN) and the gastrointestinal (GI) tract in patients of all ages. In women of menstruating age, the GYN tract is a common source of blood loss, especially when menses is heavy. The GI tract is more likely to be the source of blood loss when adults are iron deficient, especially if they possess risk factors for iron deficiency anemia, such as chronic aspirin or NSAID use.
The MCV, mean corpuscular volume , indicates the size of the red cells. If this is normal, it is described as a normocytic anemia. If the MCV is decreased, the anemia is described as a microcytic anemia. When the MCV is increased, the anemia is described as microcytic. Macrochromic does not describe red blood cells.
Lead can produce a sideroblastic anemia because it prevents iron from being incorporated into the heme portion of the hemoglobin molecule. Sideroblasts may be visible on blood smear.

Therefore, patient symptoms vary at presentation. Hepatosplenomegaly may be observed in a patient with leukemia. Sickle shaped cells are seen in patients with sickle cell anemia (SCA) and would not be observed in a patient with leukemia unless he also had sickle cell anemia.
The bone marrow produces red cells, white cells, and platelets. Clinical presentation reflects deficiency in one or more of these cell types and may be identified on CBC. Therefore, patient symptoms vary at presentation.
