Chapter 33: Management of Patients With Nonmalignant Hematologic Disorders

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.

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 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.

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 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 female patient has a hemoglobin of 6.4 g/dL and is preparing to have a blood transfusion. Why would it be important for the nurse to obtain information about the patient's history of pregnancy prior to the transfusion?

A high number of pregnancies can increase the risk of reaction. Explanation: The patient history is an important component of the pretransfusion assessment to determine the history of previous transfusions as well as previous reactions to transfusion. The history should include the type of reaction, its manifestations, the interventions required, and whether any preventive interventions were used in subsequent transfusions. The nurse assesses the number of pregnancies a woman has had, because a high number can increase her risk of reaction due to antibodies developed from exposure to fetal circulation

A nurse cares for a client with anemia requiring nutritional supplementation. Which nursing intervention best promotes client adherence with the prescribed therapy?

Assist the client to incorporate the therapeutic regimen into daily activities. Explanation: The best way for the nurse to promote adherence to the therapeutic regimen is to assist the client to incorporate the therapeutic regimen into daily activities. This action is the only answer choice that is a collaborative effort with the client and is the reason it is correct.

The nurse is planning care for a client with severe fatigue secondary to anemia. What concept will the nurse use as the basis for planning interventions?

Assisting in prioritizing activities. Explanation: When planning care for a client with severe fatigue secondary to anemia, the nurse should act collaboratively with the client and assist in prioritizing activities. The client ultimately determines the balance between rest and activity, not the nurse. The nurse will balance activities and group nursing interventions in order to prevent client fatigue.

A patient with end-stage kidney disease (ESKD) has developed anemia. What laboratory finding does the nurse understand to be significant in this stage of anemia?

Creatinine level of 6 mg/100 mL Explanation: The degree of anemia in patients with end-stage renal disease varies greatly; however, in general, patients do not become significantly anemic until the serum creatinine level exceeds 3 mg/100 mL.

The nurse should advise a client with iron deficiency anemia to take which action in order to prevent staining of the teeth?

Dilute liquid preparations of iron with juice and drink with a straw Explanation: For a client with iron deficiency anemia who is taking an oral iron supplement, the nurse instructs the client to dilute liquid preparations of iron with another liquid, such as juice, and drink with a straw to avoid staining the teeth. The nurse advises the client to take iron with or immediately after meals to avoid gastric distress. The client is advised to avoid taking iron simultaneously with an antacid, as the antacid will interfere with iron absorption

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?

Eating calf's liver with a glass of orange juice Explanation: Food sources high in iron include organ meats (e.g., beef or calf's liver, chicken liver), other meats, beans (e.g., black, pinto, and garbanzo), leafy green vegetables, raisins, and molasses. Taking iron-rich foods with a source of vitamin C (e.g., orange juice) enhances the absorption of iron.

A client with end-stage renal disease has a decreased red blood cell production. What medication can the nurse administer with physician's order that will increase the production of erythrocytes?

Epoetin alfa Explanation: The drug epoetin alfa can be used to stimulate the production of RBCs. Filgrastim and pegfilgrastim promote proliferation of neutrophils. Interleukin 2 stimulates cytokine production by lymphocytes.

A male client has a hemoglobin count of 10.2 gm/dl, a hematocrit value of 36%, and a low ferritin level. What question should the nurse ask first?

Have you experienced abdominal pain? Explanation: The laboratory data support that the client has iron-deficiency anemia. The most common cause of iron-deficiency anemia in men is bleeding from ulcers, gastritis, inflammatory bowel disease, or gastrointestinal tumors. People who experience these problems may report abdominal pain. The nurse will make further assessments and may ask the other questions.

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.

A nurse assesses a client diagnosed with megaloblastic anemia. Which clinical findings will the nurse most likely find? Select all that apply.

Jaundice Ulcerated corners of the mouth Concave nails Explanation: Megaloblastic anemia may cause angular cheilosis (ulcerated corners of the mouth), jaundice (a yellowing of the skin and sclera), and concave nails. A smooth, red tongue and restless leg syndrome are associated with iron deficiency anemia.

A nursing instructor is evaluating a student caring for a neutropenic client. The instructor concludes that the nursing student demonstrates accurate knowledge of neutropenia based on which intervention?

Monitoring the client's temperature and reviewing the client's complete blood count (CBC) with differential Explanation: Clients with neutropenia often do not exhibit classic signs of infection. Fever is the most common indicator of infection, yet it is not always present. No definite symptoms of neutropenia appear until the client develops an infection. A routine CBC with differential can reveal neutropenia before the onset of infection.

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.

A client is prescribed 325 mg/day of oral ferrous sulfate. What does the nurse include in client teaching?

Take 1 hour before breakfast Explanation: Instructions the nurse will provide for the client taking oral ferrous sulfate is to administer the medication on an empty stomach. Instructions also include that there is decreased absorption of iron with food, particularly dairy products. The client is to increase vitamin C intake (fruits, juices, tomatoes, broccoli), which will enhance iron absorption. The client is to also increase foods high in fiber to decrease risk of constipation.

A nurse is caring for a client with thalassemia who is being transfused. What is the nurse's role during a transfusion?

To closely monitor the rate of administration Explanation: In a client with thalassemia, when transfusions are necessary, the nurse closely monitors the rate of administration. Assessing for enlargement and tenderness over the liver and spleen, advising rest, or administering vitamin B12 injections are not indicated for thalassemia.

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 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.

A young client is diagnosed with a mild form of hemophilia and is experiencing bleeding in the joints with pain. In preparing the client for discharge, what instructions should the nurse provide?

Wear a medical identification bracelet. Explanation: Clients with hemophilia should wear a medical identification bracelet about having this disease. Ibuprofen interferes with platelet aggregation and may increase the client's bleeding. A warm bath may lessen pain but increase bleeding. Genetic testing and counseling are not necessary for male clients, because females are the carriers of the genetic material for hemophilia.

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 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

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.

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 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.

The client has been diagnosed with myelodysplastic syndrome with an absolute neutrophil count less than 1000/mm³ and is being admitted to the hospital. The nurse

Assigns the client to a private room Explanation: The client with an absolute neutrophil count less than 1000/mm³ is to be placed in a private room. Staff with a sore throat or cold should not be assigned to provide care for this client. The client does not need to be placed in isolation, but other neutropenic precautions need to be followed, such as allowing no visitors with infection. Water in oxygen humidifiers should be changed every 24 hours.

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.

Which of the following describes a red blood cell (RBC) that has pale or lighter cellular contents?

Hypochromic Explanation: An RBC that has pale or lighter cellular contents is hypochromic. A normocytic RBC is normal or average in size. A microcytic RBC is smaller than normal. Hyperchromic is used to describe an RBC that has darker cellular contents.

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.

Which nursing diagnosis should a nurse expect to see in a care plan for a client in sickle cell crisis

Acute pain related to sickle cell crisis Explanation: In sickle cell crisis, sickle-shaped red blood cells clump together in a blood vessel, which causes occlusion, ischemia, and extreme pain. Therefore, Acute pain related to sickle cell crisis is the appropriate choice. Although nutrition is important, poor nutritional intake isn't necessarily related to sickle cell crisis. During sickle cell crisis, pain or another internal stimulus is more likely to disturb the client's sleep than external stimuli. Although clients with sickle cell anemia can develop chronic leg ulcers caused by small vessel blockage, they don't typically experience pruritus.

A client with sickle cell crisis is admitted to the hospital in severe pain. While caring for the client during the crisis, which is the priority nursing intervention?

Administering and evaluating the effectiveness of opioid analgesics Explanation: The priority nursing intervention is to manage the acute pain. Client-controlled analgesia is frequently used in the acute care setting. A patient with sickle cell crisis experiences severe extreme pain, the use of IV fluids and oral intake is need to hydrate the patient, the patient is initially placed on bed rest during the crisis due to extreme fatigue. The patient must continue to ingest folic acid and are placed on a daily folic acid supplement

A patient describes numbness in the arms and hands with a tingling sensation. The patient also frequently stumbles when walking. What vitamin deficiency does the nurse determine may cause some of these symptoms?

B12 Explanation: The hematologic effects of vitamin B12 deficiency are accompanied by effects on other organ systems, particularly the gastrointestinal tract and nervous system. Patients with pernicious anemia may become confused; more often, they have paresthesias in the extremities (particularly numbness and tingling in the feet and lower legs). They may have difficulty maintaining their balance because of damage to the spinal cord, and they also lose position sense (proprioception).

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.

Which of the following are immunosuppressants that prevent the patient's lymphocytes from destroying the stem cells in a patient diagnosed with aplastic anemia? Select all that apply.

Cyclosporine Corticosteroids ATG Cyclophosphamide Explanation: Immunosuppressants, including cyclosporine, corticosteroids, ATG, and cyclophosphamide, prevent the patient's lymphocytes from destroying the stem cells. Filgrastim is a growth-colony stimulating factor that may be used to decease the duration and severity of neutropenia associated with aplastic 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

Which of the following is considered an antidote to heparin?

Protamine sulfate Explanation: Protamine sulfate, in the appropriate dosage, acts quickly to reverse the effects of heparin. Vitamin K is the antidote to warfarin (Coumadin). Narcan is the drug used to reverse signs and symptoms of medication-induced narcosis. Ipecac is an emetic used to treat some poisonings.

The nurse is preparing the patient for a test to determine the cause of vitamin B12 deficiency. The patient will receive a small oral dose of radioactive vitamin B12 followed by a large parenteral dose of nonradioactive vitamin B12. What test is the patient being prepared for?

Schilling test Explanation: The classic method of determining the cause of vitamin B12 deficiency is the Schilling test, in which the patient receives a small oral dose of radioactive vitamin B12, followed in a few hours by a large, nonradioactive parenteral dose of vitamin B12 (this aids in renal excretion of the radioactive dose).

The nurse, caring for a client in the emergency room with a severe nosebleed, becomes concerned when the client asks for a bedpan. The nurse documents the stool as loose, tarry, and black looking. The nurse suspects the client may have thrombocytopenia. What should be the nurse's priority action?

Notify the physician Explanation: Thrombocytopenia is evidenced by purpura, small hemorrhages in the skin, mucous membranes, or subcutaneous tissues. Bleeding from other parts of the body, such as the nose, oral mucous membrane, and the gastrointestinal tract, also occurs. Internal hemorrhage, which can be severe and even fatal, is possible. This nurse should notify the physician of the suspected disorder.

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.

Folate deficiency occurs in people who rarely eat which of the following?

Uncooked vegetables Explanation: Folate is found in green vegetables and liver. Folate deficiency occurs in people who rarely eat uncooked vegetables. Meat, fruit, and bread generally would not cause a folate deficiency.

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's family member asks the nurse why disseminated intravascular coagulation (DIC) occurs. Which statement by the nurse correctly explains the cause of DIC?

"DIC is caused by abnormal activation of the clotting pathway, causing excessive amounts of tiny clots to form inside organs." Explanation: The inflammatory response initiates the process of inflammation and coagulation. The natural anticoagulant pathways within the body are simultaneously impaired, and the fibrinolytic system is suppressed, allowing a massive amount of tiny clots forms in the microcirculation. As the platelets and clotting factors form microthrombi, coagulation fails. Thus, the paradoxical result of excessive clotting is bleeding. Decline in organ function is usually a result of excessive clot formation (with resultant ischemia to all or part of the organ)

A home care nurse visits a client diagnosed with atrial fibrillation who is ordered warfarin. The nurse teaches the client about warfarin therapy. Which statement by the client indicates the need for further teaching?

"I'll eat four servings of fresh, dark green vegetables every day." Explanation: The client requires additional teaching if he states that he'll eat four servings of dark green vegetables every day. Dark, green vegetables contain vitamin K, which reverses the effects of warfarin. The client should limit his intake to one to two servings per day. The client should report bleeding gums and severe or unexplained bruising, which may indicate an excessive dose of warfarin. The client should use an electric razor to prevent cutting himself while shaving.

A few minutes after beginning a blood transfusion, a nurse notes that a client has chills, dyspnea, and urticaria. The nurse reports this to the health care provider immediately because the client probably is experiencing which problem?

A hemolytic allergic reaction caused by an antigen reaction Explanation: Hemolytic allergic reactions are fairly common and may cause chills, fever, urticaria, tachycardia, dyspnea, chest pain, hypotension, and other signs of anaphylaxis a few minutes after blood transfusion begins. Although rare, a hemolytic reaction to mismatched blood can occur, triggering a more severe reaction and, possibly, leading to disseminated intravascular coagulation. A hemolytic reaction to Rh-incompatible blood is less severe and occurs several days to 2 weeks after the transfusion. Bacterial contamination of donor blood causes a high fever, nausea, vomiting, diarrhea, abdominal cramps and, possibly, shock.

A client is found to have a low hemoglobin and hematocrit when laboratory work was performed. What does the nurse understand the anemia may have resulted from? Select all that apply.

Blood loss Abnormal erythrocyte production Destruction of normally formed red blood cells Explanation: Most anemias result from (1) blood loss, (2) inadequate or abnormal erythrocyte production, or (3) destruction of normally formed red blood cells. The most common types include hypovolemic anemia, iron-deficiency anemia, pernicious anemia, folic acid deficiency anemia, sickle cell anemia, and hemolytic anemias. Although each form of anemia has unique manifestations, all share a common core of symptoms. Anemia does not result from infection or inadequate formed white blood cells.

Which is a symptom of hemochromatosis?

Bronzing of the skin Explanation: Clients with hemochromatosis exhibit symptoms of weakness, lethargy, arthralgia, weight loss, and loss of libido early in the illness trajectory. The skin may appear hyperpigmented from melanin deposits or appear bronze in color.

A male client has been receiving a continuous infusion of weight-based heparin for more than 4 days. The client's PTT is at a level that requires an increase of heparin by 100 units per hour. The client has the laboratory findings shown above. What is the most important action for the nurse to take?

Consult with the physician about discontinuing heparin. Explanation: Platelet counts may decrease with heparin therapy, and this client's platelet count has decreased. The client may have heparin-induced thrombocytopenia (HIT). Treatment of HIT includes discontinuing the heparin. The question asks about the most important action of the nurse and that is to consult with the physician about discontinuing heparin therapy. The nurse may continue with the current rate and should not increase the heparin dose until consulting with the physician. Warfarin is not administered until the platelet count has returned to normal levels.

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.

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

A nurse is caring for a client admitted with pernicious anemia. Which set of findings should the nurse expect when assessing the client?

Pallor, tachycardia, and a sore tongue Explanation: Pallor, tachycardia, and a sore tongue are all characteristic findings in pernicious anemia. Other clinical manifestations include anorexia; weight loss; a smooth, beefy red tongue; a wide pulse pressure; palpitations; angina pectoris; weakness; fatigue; and paresthesia of the hands and feet. Bradycardia, reduced pulse pressure, weight gain, and double vision aren't characteristic findings in pernicious anemia.

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.

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.

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.

When assessing a client with a disorder of the hematopoietic or the lymphatic system, which assessment is most essential?

Health history, such as bleeding, fatigue, or fainting Explanation: When assessing a client with a disorder of the hematopoietic or the lymphatic system, it is essential to assess the client's health history. An assessment of drug history is essential because some antibiotics and cancer drugs contribute to hematopoietic dysfunction. Aspirin and anticoagulants may contribute to bleeding and interfere with clot formation. Because industrial materials, environmental toxins, and household products may affect blood-forming organs, the nurse needs to explore exposure to these agents. Menstrual history, age, gender, and lifestyle assessments, such as exercise routines and habits, do not directly affect the hematopoietic or lymphatic system.

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

The nurse is instructing the client with sickle cell disease about the use of an inhaled vasodilator that may reduce sickling. What medication is the nurse instructing the client about?

Nitric oxide Explanation: Inhaled nitric oxide—not nitrous oxide (laughing gas), a vasodilating agent—is believed to reduce sickling by promoting the binding of oxygen to hemoglobin. It is being used in the form of handheld inhalers to abort or relieve pain experienced during sickle cell crises. Betamethasone is a corticosteroid, and terbutaline is not used as an inhaler.

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

The nurse's role in the management of polycythemia vera is primarily that of an educator. Choose the best health promotion advice that a nurse could give.

Participate in regular phlebotomy procedures to decrease blood viscosity. Explanation: Phlebotomy is a critical part of therapy and the only treatment that has demonstrated improved survival. Aspirin should be avoided, and antiplatelet therapy should be used with caution due to the risk of bleeding. Compression stockings are not necessary for walking but should be used for airplane travel.

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 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 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 registered nurse (RN) and licensed practical nurse (LPN) are preparing an educational program for clients who may be at risk for the development of iron-deficiency anemia. Which clients would receive the greatest benefit from this program? Select all that apply.

A young female client with bulimia nervosa An older adult client on a fixed income A client with Crohn's disease Explanation: Those who consume a healthy diet absorb less than 10% of the iron in food. Clients whose nutrition is compromised by unhealthy dieting or who cannot afford to eat a healthy diet, lack knowledge about nutrition, or have malabsorption disorders are at great risk for iron-deficiency anemia. A young female client with bulimia nervosa has an unhealthy diet. An older adult client on a fixed income may not have the funds to eat a healthy diet. A client with Crohn's disease has a malabsorption syndrome. A client who resides in a nursing home has prepared meals as well as available supplements if required. A client who is a vegetarian is still able to receive ample iron supplementation in the vegetables being eaten.

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 nurse is educating a client about iron supplements. The nurse teaches that what vitamin enhances the absorption of iron?

C Explanation: Vitamin C facilitates the absorption of iron. Therefore, iron supplements should be taken with a glass of orange juice or a vitamin C tablet to maximize absorption.

A client reports feeling tired, cold, and short of breath at times. Assessment reveals tachycardia and reduced energy. What would the nurse expect the physician to order?

CBC 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. A CBC would be ordered.

You are caring for a 13-year-old diagnosed with sickle cell anemia. The client asks you what they can do to help prevent sickle cell crisis. What would be an appropriate answer to this client?

Drink at least 8 glasses of water every day. Explanation: During the physical examination, observe the client's appearance, looking for evidence of dehydration, which may have triggered a sickle cell crisis. Clients are taught moderation, not avoidance of activities. Most clients with sickle cell disease are not on oxygen therapy 24/7.

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.

During the review of morning laboratory values for a client reporting severe fatigue and a red, swollen tongue, the nurse suspects chronic, severe iron deficiency anemia based on which finding?

Low ferritin level concentration Explanation: The most consistent indicator of iron deficiency anemia is a low ferritin level, which reflects low iron stores. As the anemia progresses, the MCV, which measures the size of the erythrocytes, also decreases. Hematocrit and RBC levels are also low in relation to the hemoglobin concentration.

A client diagnosed with systemic lupus erythematosus comes to the emergency department with severe back pain. The client is taking prednisone daily and reported feeling pain after manually opening the garage door. What adverse effect of long-term corticosteroid therapy is most likely responsible for the pain?

Osteoporosis Explanation: Hypertension, osteoporosis, muscle wasting, and truncal obesity are all adverse effects of long-term corticosteroid therapy; however, osteoporosis commonly causes compression fractures of the spine. Hypertension, muscle wasting, and truncal obesity aren't likely to cause severe back pain.

A client with chronic anemia has received multiple transfusions. Which client action would the nurse be concerned about relative to the client's condition?

Takes over-the-counter iron supplements Explanation: When a client receives multiple transfusions and takes iron supplements, there may be a problem with iron overload. It is recommended that clients who are experiencing anemia either avoid or limit alcohol due to interference of alcohol with utilization of essential nutrients. The typical U.S. diet includes 60 grams of protein daily. Clients may be prescribed multivitamins.

While assessing a client, the nurse will recognize what as the most obvious sign of anemia?

Pallor Explanation: On physical examination, pallor is the most common and obvious sign of anemia. Other findings may include tachycardia and flow murmurs. Patients with hemolytic anemia may exhibit jaundice and splenomegaly.

While monitoring a client for the development of disseminated intravascular coagulation (DIC), the nurse should take note of which assessment parameters?

Platelet count, prothrombin time, and partial thromboplastin time Explanation: The diagnosis of DIC is based on the results of laboratory studies of prothrombin time, platelet count, thrombin time, partial thromboplastin time, and fibrinogen level as well as client history and other assessment factors. Blood glucose levels, WBC count, calcium levels, and potassium levels aren't used to confirm a diagnosis of DIC.

Which type of hemolytic anemia is categorized as inherited disorder?

Sickle cell anemia Explanation: Glucose 6-phosphate dehydrogenase deficiency is an inherited abnormality resulting in hemolytic anemia. Autoimmune hemolytic anemia is an acquired anemia. Cold agglutinin disease is an acquired anemia. Hypersplenism results in an acquired hemolytic anemia.
