Chapter 33: Management of Patients With Nonmalignant Hematologic Disorders
A client with megaloblastic anemia reports mouth and tongue soreness. What instruction will the nurse give the client regarding eating while managing the client's symptoms?
"Eat small amounts of bland, soft foods frequently." Explanation: Because the client with megaloblastic anemia often reports mouth and tongue soreness, the nurse should instruct the client to eat small amounts of bland, soft foods frequently. The other answer choices do not factor in the client's mouth soreness or need for nutrition.
A complete blood count is commonly performed before a client goes into surgery. What does this test seek to identify?
Abnormally low hematocrit (HCT) and hemoglobin (Hb) levels Explanation: Low preoperative HCT and Hb levels indicate the client may require a blood transfusion before surgery. If the HCT and Hb levels decrease during surgery because of blood loss, the potential need for a transfusion increases. Possible renal failure is indicated by elevated BUN or creatinine levels. Urine constituents aren't found in the blood. Coagulation is determined by the presence of appropriate clotting factors, not
Which of the following is the most common hematologic condition affecting elderly patients
Anemia Explanation: Anemia is the most common hematologic condition affecting elderly patients: with each successive decade of life, the incidence of anemia increases. Thrombocytopenia is a low platelet count. Leukopenia is a low leukocyte count. Bandemia is an increased number of band cells.
The nurse is caring for a client with type 2 diabetes who take metformin to manage glucose levels. The nurse recognizes the client may be most at risk for which vitamin deficiency?
B12 Explanation: The medication metformin (Glucophage) increases the client's risk for developing B12 deficiency because the medication inhibits the absorption of B12.
When teaching a client with iron deficiency anemia about appropriate food choices, the nurse encourages the client to increase the dietary intake of which foods?
Beans, dried fruits, and leafy, green vegetables Explanation: Food sources high in iron include organ meats (e.g., beef or calf liver, chicken liver), other meats, beans (e.g., black, pinto, and garbanzo), leafy and green vegetables, raisins, and molasses. Taking iron-rich foods with a source of vitamin C (e.g., orange juice) enhances the absorption of iron.
The nurse is caring for a client with external bleeding. What is the nurse's priority intervention?
Direct pressure Explanation: Applying direct pressure to an injury is the initial step in controlling bleeding. Elevation reduces the force of flow, but direct pressure is the first step. The nurse may use pressure point control for severe or arterial bleeding. Pressure points (those areas where large blood vessels can be compressed against bone) include femoral, brachial, facial, carotid, and temporal artery sites. The nurse should avoid applying a tourniquet unless all other measures have failed, because it may further damage the injured extremity.
The nurse and the client are discussing some strategies for ingesting iron to combat the client's iron-deficiency anemia. Which is among the nurse's strategies?
Drink liquid iron preparations with a straw. Explanation: Dilute liquid preparations of iron with another liquid such as juice and drink with a straw to avoid staining the teeth. Avoid taking iron simultaneously with an antacid, which interferes with iron absorption. Drink orange juice or take other forms of vitamin C with iron to promote its absorption.
The nurse observes the laboratory studies for a client in the hospital with fatigue, feeling cold all of the time, and hemoglobin of 8.6 g/dL and a hematocrit of 28%. What finding would be an indicator of iron-deficiency anemia?
Erythrocytes that are microcytic and hypochromic Explanation: A blood smear reveals erythrocytes that are microcytic (smaller than normal) and hypochromic (lighter in color than normal). It does not reveal macrocytic (larger than normal) or hyperchromic erythrocytes. Clustering of platelets with sickled red blood cells would indicate sickle cell anemia. An increase in the number of erythrocytes would indicate polycythemia vera.
A patient with End Stage Kidney Disease is taking recombinant erythropoietin for the treatment of anemia. What laboratory study does the nurse understand will have to be assessed at least monthly related to this medication?
Hemoglobin level Explanation: When using recombinant erythropoietin, the hemoglobin must be checked at least monthly (more frequently until a maintenance dose is established) and the dose titrated to ensure the hemoglobin level does not exceed 12 g/dL.
A client is receiving chemotherapy for cancer. The nurse reviews the client's laboratory report and notes that he has thrombocytopenia. To which nursing diagnosis should the nurse give the highest priority?
Ineffective tissue perfusion: Cerebral, cardiopulmonary, GI Explanation: These are all appropriate nursing diagnoses for the client with thrombocytopenia. However, the risk of cerebral and GI hemorrhage and hypotension pose the greatest risk to the physiological integrity of the client.
While assessing a client, the nurse discovers the client has a history of restless leg syndrome. Which hematological condition does the nurse associate with this condition?
Iron deficiency anemia Explanation: Restless leg syndrome is common in as many as 24% of those with iron deficiency anemia.
The nurse observes a co-worker who always seems to be eating a cup of ice. The nurse encourages the co-worker to have an examination and diagnostic workup with the health care provider. What type of anemia is the nurse concerned the co-worker may have?
Iron deficiency anemia Explanation: People with iron deficiency anemia may crave ice, starch, or dirt; this craving is known as pica.
During a routine assessment of a patient diagnosed with anemia, the nurse observes the patient's beefy red tongue. The nurse is aware that this is a sign of what kind of anemia?
Megaloblastic Explanation: A beefy, red, sore tongue is a characteristic indicator of megaloblastic anemia. The nurse should assess for other signs such as fatigue, hypotension, and tachycardia. Safety issues should also be assessed because balance, coordination, and gait are affected.
A client with a diagnosis of pernicious anemia comes to the clinic and reports numbness and tingling in the arms and legs. What do these symptoms indicate?
Neurologic involvement Explanation: In clients with pernicious anemia, numbness and tingling in the arms and legs, and ataxia are the most common signs of neurologic involvement. Some affected clients lose vibratory and position senses. Jaundice, irritability, confusion, and depression are present when the disease is severe. Insufficient intake of dietary nutrients is not indicated by these symptoms.
A nurse is caring for a client with iron deficiency anemia. Which food or beverage will the nurse suggest to the client to eat or drink when taking supplemental iron?
Orange juice Explanation: Vitamin C found in orange juice improves the absorption of iron. The other answer choices are not the best for improving absorption of iron.
Which term refers to an abnormal decrease in white blood cells, red blood cells, and platelets?
Pancytopenia Explanation: Pancytopenia is defined as an abnormal decrease in WBCs, RBCs, and platelets. The condition may be congenital or acquired. Anemia refers to decreased red cell mass. Leukopenia refers to a less-than-normal amount of WBCs in circulation. Thrombocytopenia refers to a lower-than-normal platelet count.
A client awaiting a bone marrow aspiration asks the nurse to explain where on the body the procedure will take place. What body part does the nurse identify for the client?
Posterior iliac crest Explanation: In adults, bone marrow is usually aspirated from the posterior iliac crest and rarely from the sternum. Bone marrow is not aspirated from the femur or ankle.
The nurse obtains a unit of blood for the client, Donald D. Smith. The name on the label on the unit of blood reads Donald A. Smith. All the other identifiers are correct. What action should the nurse take?
Refuse to administer the blood Explanation: To ensure a safe transfusion, all components of the identification must be correct. The nurse should refuse to administer the blood and notify the blood bank about the discrepancy. The blood bank should then take the necessary steps to correct the name on the label on the unit of blood.
A nurse cares for clients with hematological disorders and notes that women are diagnosed with hemochromatosis at a much lower rate than men. What is the primary reason for this?
Women lose iron through menstrual cycles Explanation: Hemochromatosis is a genetic condition where excess iron is absorbed in the GI tract and deposited in various organs, making them dysfunctional. Women are often less affected than men because women lose excess iron through their menstrual cycles. The other answer choices are not correct reasons why women are impacted less than men with hemochromatosis.
A client has a history of sickle cell anemia with several sickle cell crises over the past 10 years. What blood component results in sickle cell anemia?
hemoglobin S Explanation: Hemoglobin A (HbA) normally replaces fetal hemoglobin (HbF) about 6 months after birth. In people with sickle cell anemia, however, an abnormal form of hemoglobin, hemoglobin S (HbS), replaces HbF. HbS causes RBCs to assume a sickled shape under hypoxic conditions.
A client with sickle cell anemia has a
low hematocrit. Explanation: A client with sickle cell anemia has a low hematocrit and sickled cells on the smear. A client with sickle cell trait usually has a normal hemoglobin level, a normal hematocrit, and a normal blood smear.
Which of the following are assessment findings associated with thrombocytopenia? Select all that apply.
-Bleeding gums -Epistaxis -Hematemesis Explanation: Pertinent findings of thrombocytopenia include: bleeding gums, epistaxis, hematemesis, hypotension, and tachypnea.
The thalassemias are a group of hereditary anemias characterized by which of the following? Select all that apply.
-Hypochromia -Extreme microcytosis -Hemolysis -Anemia Explanation: The thalassemias are a group of hereditary anemias characterized by hypochromia, extreme microcytosis, destruction of blood elements (hemolysis), and variable degrees of anemia. Thrombocytopenia is not associated with thalassemias.
A patient had gastric bypass surgery 3 years ago and now, experiencing fatigue, visits the clinic to determine the cause. The patient takes pantoprazole for the treatment of frequent heartburn. What type of anemia is this patient at risk for?
Pernicious anemia Explanation: A deficiency of vitamin B 12 can occur in several ways. Inadequate dietary intake is rare but can develop in strict vegans (who consume no meat or dairy products). Faulty absorption from the GI tract is a more common cause. This occurs in conditions such as Crohn's disease, or after ileal resection or gastrectomy.
A client at the clinic has just been diagnosed with iron deficiency anemia. What would you recommend the client consume to promote the absorption of iron?
Rich sources of vitamin C Explanation: Sources of vitamin C such as citrus fruits and juices, strawberries, green peppers, and tomatoes enhance the absorption of nonheme iron. To maximize nonheme iron absorption, the client should consume a rich source of vitamin C at every meal. Meat, egg yolks, oysters, and shellfish are the sources of heme iron whose absorption is influenced by body need. Vitamin E and sources of vitamin B12 do not promote the absorption of iron.
A client admitted to the hospital with abdominal pain, anemia, and bloody stools reports feeling weak and dizzy. The client has rectal pressure and needs to urinate and move their bowels. The nurse should help them:
onto the bedpan. Explanation: A client who's dizzy and anemic is at risk for injury because of his weakened state. Assisting him with the bedpan would best meet his needs at this time without risking his safety. The client may fall if walking to the bathroom, left alone to urinate, or trying to stand up.
A client is hospitalized 3 days prior to a total hip arthroplasty and reports a high level of pain with ambulation. The client has been taking warfarin at home, which is now discontinued. To prevent the formation of blood clots, which action should the nurse take?
Administer the prescribed enoxaparin (Lovenox). Explanation: Clients who are prescribed warfarin at home and need to have a major invasive procedure stop taking warfarin prior to the procedure. Low molecular weight heparin, such as enoxaparin, may be used until the procedure is performed. The client will continue with a diet that has a daily consistent amount of vitamin K. The client needs to ambulate frequently throughout the day. Prothrombin (PT) time is monitored, not PTT, when warfarin had been administered.
A young female client has pale nailbeds. Her hemoglobin count is 10.2 gm/dL and her hematocrit count is 30%. She reports fatigue and states, "I'm tired all the time." The client also reports excessive menstrual flow. The nurse assesses further and determines the client's diet is balanced and provides adequate calories. The client is prescribed supplemental iron therapy. The highest nursing diagnosis is
Altered tissue perfusion related to diminished oxygen-carrying capacity of the blood Explanation: All the nursing diagnoses are appropriate for this client who is experiencing anemia. Physiological needs take priority per Maslow's hierarchy of needs. Under physiological needs, airway, breathing, and then circulation take priority. Altered tissue perfusion would be classified under circulation, thus making it the priority over the other diagnoses listed.
Which type of sickle crisis occurs as a result of infection with the human parvovirus?
Aplastic crisis Explanation: Aplastic crisis results from infection with the human parvovirus. Sequestration crisis results when other organs pool the sickled cells. Sickle cell crisis results from tissue hypoxia and necrosis due to inadequate blood flow to a specific region of tissue or organ. Acute chest syndrome is manifested by a rapidly decreasing hemoglobin concentration, tachycardia, fever, and bilateral infiltrates seen on chest x-ray.
Which nursing intervention should be incorporated into the plan of care to manage the delayed clotting process in a client with leukemia?
Apply prolonged pressure to needle sites or other sources of external bleeding Explanation: For a client with leukemia, the nurse should apply prolonged pressure to needle sites or other sources of external bleeding. Reduced platelet production results in a delayed clotting process and increases the potential for hemorrhage. Implementing neutropenic precautions and eliminating direct contact with others are interventions to address the risk for infection.
A nurse caring for a client who has hemophilia is getting ready to take the client's vital signs. What should the nurse do before taking a blood pressure?
Ask if taking a blood pressure has ever produced bleeding under the skin or in the arm joints. Explanation: Due to the client's enhanced risk for bleeding, before taking a blood pressure, the nurse asks the client if the use of a blood-pressure cuff has ever produced bleeding under the skin or in the arm joints.
A client in end-stage renal disease is prescribed epoetin alfa and oral iron supplements. Before administering the next dose of epoetin alfa and oral iron supplement, what is the priority action taken by the nurse?
Assesses the hemoglobin level Explanation: Erythropoietin (epoetin alfa [Epogen]) with oral iron supplements can raise hematocrit levels in the client with end-stage renal disease. The nurse should check the hemoglobin prior to administration of erythropoietin, because too high a hemoglobin level can put the client at risk for heart failure, myocardial infarction, and cerebrovascular accident. Erythropoietin may be administered during dialysis treatments. The BUN will be elevated in the client with end-stage renal disease.
A client with multiple myeloma reports pain along the spinal column. The client is prescribed naproxen (Aleve) and oxycodone. Prior to administering these medications, the nurse
Checks the client's BUN and creatinine Explanation: Naproxen may cause renal dysfunction. It will be important to check and monitor the BUN and creatinine levels, which are indicators of renal function. Because of the disease, the client is not to lift more than 10 pounds and is to use correct body mechanics, by bending with the knees and not bending with the back. Both naproxen and oxycodone may be prescribed for bone pain for a client who has multiple myeloma.
A patient with chronic renal failure is examined by the health care provider for anemia. Which laboratory results will the nurse monitor?
Decreased level of erythropoietin Explanation: As renal function decreases, erythropoietin, which is produced by the kidney, also decreases. Because erythropoietin is produced outside the kidney, some erythropoiesis continues, even in patients whose kidneys have been removed. However, the number of red blood cells produced is small and the degree of erythropoiesis is inadequate.
When assessing a client with anemia, which assessment is essential?
Health history, including menstrual history in women Explanation: When assessing a client with anemia, it is essential to assess the client's health history. Women should be questioned about their menstrual periods (e.g., excessive menstrual flow, other vaginal bleeding) and the use of iron supplements during pregnancy.
A nurse provides nutritional information for a patient diagnosed with an iron-deficiency anemia. What education should the nurse provide?
Increase the intake of green, leafy vegetables. Explanation: Leafy greens, such as spinach, kale, swiss chard, collard and beet greens contain between 2.5-6.4 mg of iron per cooked cup. Clients should be encouraged to consume more green, leafy vegetables. Red meats, especially organ meats, are iron-rich foods and the client should not be discouraged from eating them. Vitamin C sources (citrus fruit and juices) enhance the absorption of iron, which should be taken 1 hour before or 2 hours after a meal.
A client with severe anemia reports symptoms of tachycardia, palpitations, exertional dyspnea, cool extremities, and dizziness with ambulation. Laboratory test results reveal low hemoglobin and hematocrit levels. Based on the assessment data, which nursing diagnoses is most appropriate for this client?
Ineffective tissue perfusion related to inadequate hemoglobin and hematocrit Explanation: The symptoms indicate impaired tissue perfusion due to a decrease in the oxygen-carrying capacity of the blood. Cardiac status should be carefully assessed. 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. Heart failure may eventually develop, as evidenced by an enlarged heart (cardiomegaly) and liver (hepatomegaly) and by peripheral edema.
The nurse is performing an assessment for a client with anemia admitted to the hospital to have blood transfusions administered. Why would the nurse need to include a nutritional assessment for this patient?
It may indicate deficiencies in essential nutrients. Explanation: A nutritional assessment is important, because it may indicate deficiencies in essential nutrients such as iron, vitamin B12, and folate.
A client has hereditary hemochromatosis. Laboratory test results indicate an elevated serum iron level, high transferrin saturation, and normal complete blood count (CBC). What is most important action for the nurse to take?
Remove the prescribed one unit of blood. Explanation: Treatment for hemochromatosis is phlebotomy or removal of whole blood from a vein to reduce iron. Limiting dietary intake of iron is not an effective treatment. The client needs to perform activities to protect the liver, such as limiting alcohol ingestion. The definitive test for hemochromatosis had been a liver biopsy, but now genetic testing is performed. A liver biopsy could be performed to determine liver damage. However, this does not address the most immediate problem of too high iron.
An older adult client who is a vegetarian has a hemoglobin of 10.2 gm/dL, vitamin B12 of 68 pg/mL (normal: 200-900 pg/mL), and MCV of 110 cubic micrometers. After interpreting the data, what instruction should the nurse give to the client?
Supplement the diet with vitamin B12. Explanation: Data support that the client is experiencing megaloblastic anemia. Findings include the laboratory test results, the client's older age, and the client's status as a vegetarian. Many vegetarians need to supplement their diet with vitamin B12. Eating more foods with vitamin B12 will not provide enough of this vitamin for the client's body. Increasing iron sources will not resolve the client's anemia. Telling the client to discontinue the vegetarian practice and eat red meat is nontherapeutic.
Which of the following is accurate regarding the use of corticosteroids for immune hemolytic anemia? Select all that apply.
They decrease the macrophages ability to clear the antibody-coated RBCs. If the hemoglobin returns to normal, the corticosteroid dose can be lowered. Explanation: The treatment consists of high doses of corticosteroids until hemolysis decreases. Corticosteroids decrease the macrophage's ability to clear the antibody-coated RBCs. If the hemoglobin level returns to normal, usually after several weeks, the corticosteroid dose can be lowered or, in some cases tapered and discontinued.
After receiving chemotherapy for lung cancer, a client's platelet count falls to 98,000/mm3. What term should the nurse use to describe this low platelet count?
Thrombocytopenia Explanation: A normal platelet count is 140,000 to 400,000/mm3 in adults. Chemotherapeutic agents produce bone marrow depression, resulting in reduced red blood cell counts (anemia), reduced white blood cell counts (leukopenia), and reduced platelet counts (thrombocytopenia). Neutropenia is the presence of an abnormally reduced number of neutrophils in the blood and is caused by bone marrow depression induced by chemotherapeutic agents.
A nurse on a hematology/oncology floor is caring for a client with aplastic anemia. Which would not be included in the client's discharge instructions?
Use a disposable razor when shaving. Explanation: People with aplastic anemia usually have insufficient erythrocytes, leukocytes, and platelets. Encourage behaviors that will lower the risk for bleeding. Avoiding contact with people who are sick reduces the risk of acquiring an infection. Handwashing reduces the risk of acquiring an infection. Anemia can cause fatigue and shortness of breath with even mild exertion.
A nurse is caring for a client with thrombocytopenia. What is the best way to protect this client?
Use the smallest needle possible for injections. Explanation: Because thrombocytopenia alters coagulation, it poses a high risk of bleeding. To help prevent capillary bleeding, the nurse should use the smallest needle possible when administering injections. The nurse doesn't need to limit visits by family members because they don't pose any danger to the client. The nurse should provide comfort measures and maintain the client on bed rest; activities such as using a wheelchair can cause bleeding. The nurse records fluid intake and output to monitor hydration; however, this action doesn't protect the client from a complication of thrombocytopenia.
A client is seen in the emergency department with severe pain related to a sickle cell crisis. What does the nurse understand is occurring with this client?
Vascular occlusion in small vessels decreasing blood and oxygen to the tissues. Explanation: The person with sickle cell disease repeatedly suffers from two major problems: (1) episodes of sickle cell crisis from vascular occlusion, which develops rapidly under hypoxic conditions, and (2) chronic hemolytic anemia. During a sickle cell crisis, the sickle-shaped cells lodge in small blood vessels, where they block the flow of blood and oxygen to the affected tissue. The vascular occlusion induces severe pain in the ischemic tissue. The client may have increased tolerance for pain due to the chronic nature of the illness. Bone marrow increases the erythrocyte production. Underhydration increases the client's risk of developing a vaso-occlusive crisis.
The most common cause of iron deficiency anemia in men and postmenopausal women is
bleeding. Explanation: The most common cause of iron deficiency anemia in men and postmenopausal women is bleeding from ulcers, gastritis, inflammatory bowel disease or gastrointestinal (GI) tumors. Menorrhagia is the most common cause in premenopausal women. Iron malabsorption is another cause, which is seen in clients with celiac disease. Clients with chronic alcoholism often have chronic blood loss from the GI tract.
A client has pernicious anemia and has been receiving treatment for several years. Which symptom may be confused with another condition in older adults?
dementia Explanation: Pernicious anemia may be accompanied by a dementia with symptoms similar to Alzheimer's disease. Therefore, clients experiencing cognitive changes should be screened because early detection of pernicious anemia is critical to prevent neurologic damage.
The nurse is collecting data for a client who has been diagnosed with iron-deficiency anemia. What subjective findings does the nurse recognize as symptoms related to this type of anemia?
"I have difficulty breathing when walking 30 feet." Explanation: Most clients with iron-deficiency anemia have reduced energy, feel cold all the time, and experience fatigue and dyspnea with minor physical exertion. The heart rate usually is rapid even at rest. The CBC and hemoglobin, hematocrit, and serum iron levels are decreased. The client would feel cold and not hot. The client is fatigue and able to sleep often with a decrease in appetite, not an increase.
A pregnant woman is hospitalized as the result of sickle-cell crisis. Which finding indicates the outcome has been achieved for this client?
Reports joint pain less than 3 on a scale of 0 to 10 Explanation: An expected outcome for a client experiencing a sickle-cell crisis is control and reduction of pain. Hydroxyurea is contraindicated in pregnancy because of the risk it poses for congenital abnormalities. An indication that the client is free from infection is exhibiting a normal temperature; 100.3°F is an elevated temperature. To minimize crises, the client needs to stay warm not cool.
A client with pernicious anemia is receiving parenteral vitamin B12 therapy. Which client statement indicates effective teaching about this therapy?
"I will receive parenteral vitamin B12 therapy for the rest of my life." Explanation: Because a client with pernicious anemia lacks intrinsic factor, oral vitamin B12 can't be absorbed. Therefore, parenteral vitamin B12 therapy is recommended and required for life.
A clinical nurse specialist (CNS) is orienting a new graduate registered nurse to an oncology unit where blood product transfusions are frequently administered. In discussing ABO compatibility, the CNS presents several hypothetical scenarios. The new graduate knows that the greatest likelihood of an acute hemolytic reaction would occur when giving:
A-positive blood to an A-negative client. Explanation: An acute hemolytic reaction occurs when there is an ABO or Rh incompatibility. For example, giving A blood to a B client would cause a hemolytic reaction. Likewise, giving Rh-positive blood to an Rh-negative client would cause a hemolytic reaction. It's safe to give Rh-negative blood to an Rh-positive client if there is a blood type compatibility. O-negative blood is the universal donor and can be given to all other blood types. AB clients can receive either A or B blood as long as there isn't an Rh incompatibility.
A client is treated for anemia. What is the nurse's best understanding about the correlation between anemia and the client's iron stores?
There is a strong correlation between iron stores and hemoglobin levels. Explanation: A strong correlation exists between laboratory values that measure iron stores and hemoglobin levels. After iron stores are depleted (as reflected by low serum ferritin levels), the hemoglobin level falls.
An client has pernicious anemia and has been receiving treatment for several years. What is the client lacking that results in pernicious anemia?
There is a strong correlation between iron stores and hemoglobin levels. Explanation: A strong correlation exists between laboratory values that measure iron stores and hemoglobin levels. After iron stores are depleted (as reflected by low serum ferritin levels), the hemoglobin level falls.
During preparation for bowel surgery, a client receives an antibiotic to reduce intestinal bacteria. The nurse knows that hypoprothrombinemia may occur as a result of antibiotic therapy interfering with synthesis of which vitamin?
Vitamin K Explanation: Intestinal bacteria synthesize such nutritional substances as vitamin K, thiamine, riboflavin, vitamin B12, folic acid, biotin, and nicotinic acid. Antibiotic therapy may interfere with synthesis of these substances, including vitamin K. Intestinal bacteria don't synthesize vitamins A, D, or E.
The nurse is educating a patient with iron deficiency anemia about food sources high in iron and how to enhance the absorption of iron when eating these foods. What can the nurse inform the client would enhance the absorption?
intrinsic factor Explanation: Pernicious anemia develops when a client lacks intrinsic factor, which normally is present in stomach secretions. Intrinsic factor is necessary for absorption of vitamin B12. Vitamin B12, the extrinsic factor in blood, is required for the maturation of erythrocytes.
