Ch 29 HInkle: Nonmalignant Hematologic Disorders
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 when hemolytic processes destroy erythrocytes." "DIC occurs when the immune system attacks platelets and causes massive bleeding." "DIC is a complication of an autoimmune disease that attacks the body's own cells." "DIC is caused by abnormal activation of the clotting pathway, causing excessive amounts of tiny clots to form inside organs."
"DIC is caused by abnormal activation of the clotting pathway, causing excessive amounts of tiny clots to form inside organs." 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 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 larger amounts of bland, soft foods less frequently." "Eat cold, bland foods with a large amount of water." "Eat small amounts of bland, soft foods frequently." "Eat low-fiber blended foods only."
"Eat small amounts of bland, soft foods frequently." 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.
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." "I have an increase in my appetite." "I feel hot all of the time." "I have a difficult time falling asleep at night."
"I have difficulty breathing when walking 30 feet." 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 fatigued and able to sleep often with a decrease in appetite, not an increase.
A client with anemia is prescribed an oral iron supplement. Which statement indicates that teaching about this supplement has been effective? "I will take it in the morning with orange juice." "I will limit my intake of raw fruit and vegetables." "I will be sure to take this medication with food." "I will stop taking it if my stool turns black."
"I will take it in the morning with orange juice." The client should be instructed to take the iron supplements on an empty stomach with a source of vitamin C such as orange juice. Iron supplements will turn the stool dark or black; this does not indicate that the supplement should be stopped. The supplement should be taken 1 hour before meals or 2 hours after a meal and not with a meal. The client should be instructed to increase the intake of high-fiber foods to reduce the risk of constipation.
Parents arrive to the clinic with their young child and inform the nurse the child has just been diagnosed with sickle cell disease. The parents ask the nurse how this could have happened and which one of them is the carrier. What is the best response by the nurse? "It is an acquired, not a hereditary disorder." "The trait is passed down through the mother." "The child must inherit two defective genes, one from each parent." "Most likely, the father is the carrier of the gene."
"The child must inherit two defective genes, one from each parent." Sickle cell disease is a hereditary disorder. To manifest this disorder, a person must inherit two defective genes, one from each parent, in which case all the hemoglobin is inherently abnormal. If the person inherits only one gene, the person carries the sickle cell trait. The hemoglobin of those who have sickle cell trait is about 40% affected. The other distractors are incorrect due to these factors.
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 reaction caused by bacterial contamination of donor blood A hemolytic reaction to mismatched blood A hemolytic reaction to Rh-incompatible blood A hemolytic allergic reaction caused by an antigen reaction
A hemolytic allergic reaction caused by an antigen reaction 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 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: O-positive blood to an A-positive client. O-negative blood to an O-positive client. B-positive blood to an AB-positive client. A-positive blood to an A-negative client.
A-positive blood to an A-negative client. 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 complete blood count is commonly performed before a client goes into surgery. What does this test seek to identify? Electrolyte imbalance that could affect the blood's ability to coagulate properly Low levels of urine constituents normally excreted in the urine Potential hepatic dysfunction indicated by decreased blood urea nitrogen (BUN) and creatinine levels Abnormally low hematocrit (HCT) and hemoglobin (Hb) levels
Abnormally low hematocrit (HCT) and hemoglobin (Hb) levels 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 electrolytes.
A client's low prothrombin time (PT) was attributed to low vitamin K levels and the client's PT normalized after administration of vitamin K. When performing discharge education in an effort to prevent recurrence, what should the nurse emphasize? Avoidance of NSAIDs Meticulous hygiene Adequate nutrition Constant access to clotting factor concentrates
Adequate nutrition Vitamin K deficiency is often the result of a nutritional deficit. NSAIDs do not influence vitamin K synthesis and clotting factors are not necessary to treat or prevent a vitamin K deficiency. Hygiene is not related to the onset or prevention of vitamin K deficiency.

The nurse is talking with the parents of a toddler who was diagnosed with hemophilia A. What instruction should the nurse give to the parents? Encourage the toddler to participate in playground activities with other toddlers Use nasal packing for any nose bleeds Administer factor VIII intravenously at the first sign of bleeding Administer over-the-counter preparations for a cold
Administer factor VIII intravenously at the first sign of bleeding Clients and families are taught to administer factor VIII intravenously. This helps to prevent bleeding episodes. Activities that minimize trauma are allowed for the toddler, however, playground activities may place the toddler at risk for increased bleeding. Over-the-counter cold preparations are to be avoided because they will interfere with platelet aggregation. Nasal packing is avoided because when the nasal packing is removed, bleeding may occur.
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? Encourage a diet high in vitamin K. Administer the prescribed enoxaparin (Lovenox). Have the client limit physical activity. Monitor partial thromboplastin (PTT) time.
Administer the prescribed enoxaparin (Lovenox). 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 Thrombocytopenia Leukopenia Bandemia
Anemia 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 cell
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: Changes the water in the humidifier for oxygen therapy every 48 hours Places the client in isolation and allows no visitors Allows unlicensed assistive personnel who reports having a sore throat to provide care Assigns the client to a private room
Assigns the client to a private room 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.
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 use a medication reminder system for the therapeutic regimen. Develop a therapeutic regimen recommendation for the client. Develop a therapeutic regimen based on the client's understanding of the medication. Assist the client to incorporate the therapeutic regimen into daily activities.
Assist the client to incorporate the therapeutic regimen into daily activities. 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? Encouraging early and frequent activities. Keeping long activity periods to build client stamina. Assisting in prioritizing activities. Determining what days to be active.
Assisting in prioritizing activities. 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 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? Iron Folate Thiamine B12
B12 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).
The most common cause of iron deficiency anemia in men and postmenopausal women is: iron malabsorption. chronic alcoholism. menorrhagia. bleeding.
Bleeding. 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.
The nurse is caring for an older adult client who has been admitted to the unit with anemia. What would the nurse expect the client to possibly exhibit? Excessive consumption of coffee or tea Elimination of iron by the body Decrease in the total body iron stores with age Blood loss from the gastrointestinal or genitourinary tract
Blood loss from the gastrointestinal or genitourinary tract If an older adult is anemic, blood loss from the gastrointestinal or genitourinary tract is suspected. This is because iron-deficiency anemia is unusual in older adults as the body does not eliminate excessive iron, causing total body iron stores to increase with age. Excessive consumption of coffee or tea is not a causative factor for anemia in older adults.
Which is a symptom of hemochromatosis? Inflammation of the tongue Weight gain Bronzing of the skin Inflammation of the mouth
Bronzing of the skin 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.
The nurse is educating a client about iron supplements. The nurse teaches that what vitamin enhances the absorption of iron? A D C E
C 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 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 Instructs the client not to lift more than 20 pounds Questions the physician about the use of both medications Teaches the client to bend at the back when lifting objects
Checks the client's BUN and creatinine 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 total iron-binding capacity Increased mean corpuscular volume Increased reticulocyte count Decreased level of erythropoietin
Decreased level of erythropoietin 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 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 leafy green vegetables with a glass of water Eating a steak with mushrooms Eating apple slices with carrots Eating calf's liver with a glass of orange juice
Eating calf's liver with a glass of orange juice 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 vita min C (e.g., orange juice) enhances the absorption of iron.
Which of the following are assessment findings associated with thrombocytopenia? Select all that apply. Hypertension Epistaxis Bradypnea Hematemesis Bleeding gums
Epistaxis Hematemesis Bleeding gums Pertinent findings of thrombocytopenia include: bleeding gums, epistaxis, hematemesis, hypotension, and tachypnea.
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 Erythrocytes that are macrocytic and hyperchromic An increased number of erythrocytes Clustering of platelets with sickled red blood cells
Erythrocytes that are microcytic and hypochromic 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 has been diagnosed with thrombocytopenia. What are the primary nursing interventions while instituting corticosteroid therapy in this patient? Examine the extremities for redness. Palpate the lymph nodes and tonsils every shift. Eliminate aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). Gradually taper the dose and frequency of medication.
Gradually taper the dose and frequency of medication. For a patient with thrombocytopenia, he or she gradually tapers the dose and frequency of steroid medication before discontinuing it to avoid adrenal insufficiency or crisis. Eliminating aspirin and NSAIDS will help manage bleeding tendencies. Assessment of the extremities, tonsils, or the lymph nodes is part of a physical examination of a patient and not applicable to corticosteroid therapy.
A patient has a probable diagnosis of polycythemia vera. The nurse reviews the patient's lab work for which diagnostic indicator? Hematocrit of 60% Erythrocyte count of 6.5 m/?L Leukocyte count of 11,500/mm3 Platelet value of 350,000/mm3
Hematocrit of 60% Although all results are elevated, the diagnostic indicator is the elevated hematocrit (normal = 42% to 52% for a male). These results are used in combination with other indicators (e.g., splenomegaly) for a definitive diagnosis.
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 Creatinine level Folate levels Potassium level
Hemoglobin level 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? Impaired oral mucous membranes Impaired tissue integrity Activity intolerance Ineffective tissue perfusion: Cerebral, cardiopulmonary, GI
Ineffective tissue perfusion: Cerebral, cardiopulmonary, GI 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.
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 is part of the required assessment information. It will determine what type of anemia the patient has. It is important for the nurse to determine what type of foods the patient will eat. It may indicate deficiencies in essential nutrients.
It may indicate deficiencies in essential nutrients. A nutritional assessment is important, because it may indicate deficiencies in essential nutrients such as iron, vitamin B12, and folate.
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? Elevated red blood cell (RBC) count Elevated hematocrit concentration Enlarged mean corpuscular volume (MCV) Low ferritin level concentration
Low ferritin level concentration 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 with sickle cell anemia has a: low hematocrit. high hematocrit. normal hematocrit. normal blood smear.
Low hematocrit. 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 with a diagnosis of pernicious anemia comes to the clinic reporting of numbness and tingling in his arms and legs. What do these symptoms indicate? Severity of the disease Insufficient intake of dietary nutrients Loss of vibratory and position senses Neurologic involvement
Neurologic involvement 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
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? Put in an IV line Stop the nosebleed Ask someone to clean the bedpan Notify the physician
Notify the physician 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 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. to a standing position so he can urinate. to the bathroom. to the bedside commode.
Onto the bedpan. 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 u
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? Hypertension Muscle wasting Truncal obesity Osteoporosis
Osteoporosis 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 nurse is caring for a client admitted with pernicious anemia. Which set of findings should the nurse expect when assessing the client? Pallor, bradycardia, and reduced pulse pressure Angina pectoris, double vision, and anorexia Pallor, tachycardia, and a sore tongue Sore tongue, dyspnea, and weight gain
Pallor, tachycardia, and a sore tongue 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 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 Aplastic anemia Iron deficiency anemia Sickle cell anemia
Pernicious anemia 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 nurse is developing a care plan for a client with disseminated intravascular coagulation (DIC). Which nursing intervention should the nurse include? Provide mouth care every 4 hours with lemon-glycerin swabs. Place a pressure-reducing mattress on the client's bed. Administer meperidine (Demerol) I.M. as needed for pain. Administer aspirin daily as ordered.
Place a pressure-reducing mattress on the client's bed. A client with DIC is at risk for Impaired skin integrity secondary to bleeding or ischemia. The nurse should place the client on a pressure-reducing mattress and perform skin care every 2 hours. The nurse should avoid administering any medication that decreases platelet function, such as aspirin. The nurse should perform mouth care using sponge swabs and baking soda solution, not lemon-glycerin swabs, because lemon-glycerin swabs can dry the oral mucosa, which may lead to bleeding. I.M. injections should be avoided in clients with DIC because of the potential for bleeding.
While monitoring a client for the development of disseminated intravascular coagulation (DIC), the nurse should take note of which assessment parameters? Platelet count, blood glucose levels, and white blood cell (WBC) count Thrombin time, calcium levels, and potassium levels Platelet count, prothrombin time, and partial thromboplastin time Fibrinogen level, WBC, and platelet count
Platelet count, prothrombin time, and partial thromboplastin time 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.
A young mother with a 2 year old and a 6 month old is experiencing fatigue related to anemia. The client states that she is having difficulty performing the activities needed for her job, family, and home. With what task is it most appropriate for the nurse to assist the client? Requesting a leave of absence from her job. Finding a babysitter to take care of her children. Prioritizing and balancing activities and rest. Obtaining assistance from someone to help with cleaning in the home.
Prioritizing and balancing activities and rest. Fatigue is the most common symptom and complication of anemia. The nurse should assist the client to prioritize activities and to establish a balance between activity and rest that the client finds acceptable. With the other options, the nurse is jumping to conclusions that these things will help the client.
Which of the following is considered an antidote to heparin? Protamine sulfate Narcan Vitamin K Ipecac
Protamine sulfate 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.
A pregnant woman is hospitalized as the result of sickle-cell crisis. Which finding indicates the outcome has been achieved for this client? Exhibits a temperature more than 100.3°F Reports joint pain less than 3 on a scale of 0 to 10 Takes hydroxyurea during her pregnancy Describes the importance of staying cool
Reports joint pain less than 3 on a scale of 0 to 10 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 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 Sources of vitamin B12 Meat, egg yolks, oysters, and shellfish Vitamin E
Rich sources of vitamin C 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.
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? Bone marrow biopsy Bone marrow aspiration Magnetic resonance imaging (MRI) study Schilling test
Schilling test 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).
A client with chronic anemia has received multiple transfusions. Which client action would the nurse be concerned about relative to the client's condition? Eliminates use of alcohol Takes 60 grams of protein each day Takes a daily multiple vitamin pill Takes over-the-counter iron supplements
Takes over-the-counter iron supplements 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.
A patient is taking prednisone 60 mg per day for the treatment of an acute exacerbation of Crohn's disease. The patient has developed lymphopenia with a lymphocyte count of less than 1,500 mm3. What should the nurse monitor the client for? Bleeding The onset of a bacterial infection Diarrhea Abdominal pain
The onset of a bacterial infection Lymphopenia (a lymphocyte count less than 1,500/mm3) can result from ionizing radiation, long-term use of corticosteroids, uremia, infections (particularly viral infections), some neoplasms (e.g., breast and lung cancers, advanced Hodgkin disease), and some protein-losing enteropathies (in which the lymphocytes within the intestines are lost) (Kipps, 2010). When lymphopenia is mild, it is often without sequelae; when severe, it can result in bacterial infections (due to low B lymphocytes) or in opportunistic infections (due to low T lymphocytes).
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 Leukopenia Neutropenia Anemia
Thrombocytopenia 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 is caring for a client with thalassemia who is being transfused. What is the nurse's role during a transfusion? To assess for enlargement and tenderness over the liver and spleen To instruct the client to rest immediately if chest pain develops To administer vitamin B12 injections To closely monitor the rate of administration
To closely monitor the rate of administration 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.
The nurse caring for an older adult with a diagnosis of leukemia would encourage the client to use an electric razor. What is the rationale for this statement by the nurse? The client is at risk for spontaneous and uncontrolled bleeding. Strong tissues and intact clotting mechanisms may prevent hemorrhage. Trauma and microabrasions from a non-electric razor may contribute to anemia. The client is not at risk for infection from microorganisms.
Trauma and microabrasions from a non-electric razor may contribute to anemia. In a client with leukemia who is at risk for hemorrhage, the nurse handles the client gently when assisting and encourages the client to use electric razors. Trauma and microabrasions from razors may contribute to anemia from bleeding. Fragile tissues and altered clotting mechanisms may result in hemorrhage even after minor trauma. Therefore, the nurse inspects the skin for signs of bruising and petechiae and reports melena, hematuria, or epistaxis (nosebleeds). The risks for spontaneous and uncontrolled bleeding or infection from microorganisms are not addressed by the use of electric razors.
When evaluating a patient's symptoms that are consistent with a diagnosis of leukemia, the nurse is aware that all leukemias have which common feature? Compensatory polycythemia stimulated by thrombocytopenia Reduced plasma volume in response to a reduced production of cellular elements Unregulated accumulation of white cells in the bone marrow, which replace normal marrow elements Increased blood viscosity, resulting from an overproduction of white cells
Unregulated accumulation of white cells in the bone marrow, which replace normal marrow elements The term leukemia means "white blood," which is used to describe the neoplastic proliferation of one hematopoietic cell type (granulocytes, monocytes, lymphocytes, and sometimes, erythrocytes and megakaryocytes).
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? Avoid contact with family/friends who are sick. Use a disposable razor when shaving. Plan for frequent periods of rest. Encourage frequent handwashing.
Use a disposable razor when shaving. 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. The client has a decreased tolerance of pain related to the chronic nature of the illness. Bone marrow decreases the erythrocyte production causing decrease in hypoxia. Overhydration enlarges the red blood cells.
Vascular occlusion in small vessels decreasing blood and oxygen to the tissues. 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? Take warm baths to lessen pain. Undergo genetic testing and counseling if the client is male. Take ibuprofen for joint pain. Wear a medical identification bracelet.
Wear a medical identification bracelet. 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 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 A hemoglobin F hemoglobin M hemoglobin S
hemoglobin S 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.
An client has pernicious anemia and has been receiving treatment for several years. What is the client lacking that results in pernicious anemia? hemoglobin intrinsic factor extrinsic factor vitamin B
intrinsic factor 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.
