Chapter 28: Assessment of Hematologic Function and Treatment Modalities

A client wants to donate blood before his or her abdominal surgery next week. What should be the nurse's first action?

Explain the time frame needed for autologous donation. -Preoperative autologous donations are ideally collected 4 to 6 weeks before surgery. The nurse should first explain that time frame to this client. Surgery is scheduled in one week which means that autologous blood donation may not be an option for this client. A list of donation centers can be provided to the client; and even though iron is recommended and 2 units of blood may be suggested, the first action is to tell the client about the needed time frame for donation.

A nurse is performing an initial assessment and notes the client's skin is a gray-tan color, especially on the scars of the client's arms. Which hematological condition does the nurse suspect?

Hemochromatosis -Hemochromatosis is an autosomal recessive disease of excessive iron absorption. This results in bronze or gray-tan skin, especially over scars. The other answer choices are hematological conditions; however, these do not cause the skin to turn a gray-tan color.

A nurse is reviewing a client's morning laboratory results and notes a left shift in the band cells. Based on this result, the nurse can interpret that the client

may be developing an infection.

A nurse is reviewing a client's most recent platelet count and identifies the need to institute bleeding precautions. Which result would the nurse most likely have noted?

45,000/mm3 -Bleeding precautions are recommended for clients with a platelet count of less than 50,000/mm3.

The physician orders a transfusion with packed red blood cells (RBCs) for a client hospitalized with severe iron deficiency anemia. When blood is administered, what is the most important action the nurse can take to prevent a transfusion reaction?

Verify the client's identity according to hospital policy

Place the following procedural steps in order for transfusing a unit of packed red blood cells (PRBCs).

Start an intravenous line. Obtain the unit of PRBCs from the blood bank. Double check the labels with another nurse to ensure correct ABO group and Rh type. Initiate the blood transfusion within 30 minutes of receipt. Monitor closely for signs of a transfusion reaction.

A preoperative client is discussing blood donation with the nurse. Which statement by the client indicates to the nurse the need for further teaching?

"My family will donate blood, because it's safer." -Directed donations from friends and family members are not any safer than those provided by random donors. Withdrawal of 450 mL of blood usually takes about 15 minutes. Specimens from donated blood are tested to detect infections and to identify the specific blood type. Autologous blood donation is useful for many elective surgeries where the potential need for transfusion is high.

A client is returning home after having a bone marrow aspiration and biopsy. Which statement indicates that teaching by the nurse has been effective?

"The area might ache for 1 to 2 days." -Potential complications of either bone marrow aspiration or biopsy include bleeding and infection. After the marrow sample is obtained, pressure is applied to the site for several minutes. The site is then covered with a sterile dressing. Most clients have no discomfort after a bone marrow aspiration, but the site of a biopsy may ache for 1 or 2 days. The client should be instructed to perform no rigorous activity for 1 to 2 days. Aspirin-containing analgesics should be avoided immediately after the procedure as this might cause or aggravate bleeding. Rigorous exercise should be avoided for 1 to 2 days.

A nurse is caring for a client who will undergo total knee replacement and will have an autologous transfusion. Which statement will the nurse include when teaching the client about the transfusion?

"You typically donate blood 4 to 6 weeks before the surgery." -With autologous donation, a client's own blood may be collected for future transfusion; this is an effective method for orthopedic surgery, where the likelihood of transfusion is high. Preoperative donation is ideally collected 4-6 weeks before surgery. The nurse will not tell the client that the blood will not be needed; orthopedic surgeries often require transfusion of blood. The client will be prescribed iron supplements during the donation time, not calcium.

A client feels faint and becomes dizzy after donating a unit of blood. Which actions will the nurse perform at this time? Select all that apply.

- Assist the client to lie down - Assess the client's apical heart rate - Place the client's head lower than the knees - Observe the clent for 30 minutes

When conducting a health assessment on a client suspected for having a hematological disorder, the nurse should collect which data? Select all that apply.

- Dietary intake - Medication use - Ethnicity - Herbal supplements

A client with a history of congestive heart failure has an order to receive 1 unit of packed red blood cells (RBCs). If the nurse hangs the blood at 12:00 pm, by what time must the infusion be completed?

4:00 pm -When packed red blood cells (PRBCs) or whole blood is transfused, the blood should be administered within a 4-hour period because warm room temperatures promote bacterial growth.

A client with Hodgkin disease had a bone marrow biopsy yesterday and reports aching at the biopsy site, rated a 5 (on a 1-10 scale). After assessing the biopsy site, which nursing intervention is most appropriate?

Administer acetaminophen 500 mg po, as ordered

The physician performs a bone marrow biopsy from the posterior iliac crest on a client with pancytopenia. What intervention should the nurse perform after the procedure?

Apply pressure over the site for 5-7 minutes -Hazards of either bone marrow aspiration or biopsy include bleeding and infection. The risk of bleeding is somewhat increased if the client's platelet count is low or if the client has been taking a medication (e.g., aspirin) that alters platelet function. After the marrow sample is obtained, pressure is applied to the site for several minutes. The site is then covered with a sterile dressing.

A patient with chronic kidney disease is being examined by the nurse practitioner for anemia. The nurse has reviewed the laboratory data for hemoglobin and RBC count. What other test results would the nurse anticipate observing?

Decreased level of erythropoietin

The nurse expects which assessment finding when caring for a client with a decreased hemoglobin level?

Decreased oxygen level.

A client donated two units of blood to be used for transfusion during spinal fusion surgery. The client received one unit of autologous blood during the procedure but the second unit is not needed during the procedure. The nurse knows which action will come after the procedure is completed?

Discard the additional unit. -In autologous donation, the client's own blood is collected for a future transfusion, particularly for an elective surgery where the potential for transfusion is high, such as an orthopedic procedure. If the blood is not used, it is discarded. The blood is not used for its components. The client will not be given the unit of blood unless it is required. The additional unit will not be released to the general population for use.

A client receiving a unit of packed red blood cells (PRBCs) has been prescribed morphine 1 mg intravenously now for pain. What is the best method for the nurse to administer the morphine?

Disconnect the blood tubing, flush with normal saline, and administer morphine. -Never add medications to blood or blood products. The transfusion must be temporarily stopped in order to administer the morphine.

A client is prescribed to receive 2 units of fresh frozen plasma (FFP). Place in order the steps the nurse will take to administer this blood product to the client.

Ensure a 22-gauge catheter is in place Obtain the FFP from the blood bank Double-check the blood labels with another nurse Begin infusion Observe the client for signs of an adverse reaction Monitor vital signs at the conclusion of the transfusion Flush the intravenous line with saline after the transfusion

A client with severe anemia is admitted to the hospital. Because of religious beliefs, the client is refusing blood transfusions. The nurse anticipates pharmacologic therapy with which drug to stimulate the production of red blood cells?

Epoetin alfa -Erythropoietin (epoetin alfa) is an effective alternative treatment for clients with chronic anemia secondary to diminished levels of erythropoietin. This medication stimulates erythropoiesis. Filgratism ( Neupogen) and Sargramostim stimulate granulocytosis( increasing WBC count) , Eltrombopag (Promacta) is used to treat aplastic anemia and thrombocytopenia.

Which term describes the percentage of blood volume that consists of erythrocytes?

Hematocrit

A nurse is caring for a patient who has had a bone marrow aspiration with biopsy. What complication should the nurse be aware of and monitor the patient for?

Hemorrhage

The nurse is preparing a patient for a bone marrow aspiration and biopsy from the site of the posterior superior iliac crest. What position will the nurse place the patient in?

Lateral position with one leg flexed -Bone marrow aspiration procedure. The posterior superior iliac crest is the preferred site for bone marrow aspiration and biopsy because no vital organs or vessels are nearby. The patient is placed either in the lateral position with one leg flexed or in the prone position.

What food should the nurse recommend for a client diagnosed with vitamin B12 deficiency?

Lean meat -Vitamin B12 is only found in foods of animal origin. Therefore, whole-grain bread, green vegetables, and citrus fruit do not contain this vitamin.

Albumin is important for the maintenance of fluid balance within the vascular system. Albumin is produced by which of the following?

Liver

Which cell of hematopoiesis is responsible for the production of red blood cells (RBCs) and platelets?

Myeloid stem cell -The myeloid stem cell is responsible not only for all nonlymphoid white blood cells, but also for the production of red blood cells and platelets. Lymphoid cells produce either T or B lymphocytes. A monocyte is large WBC that becomes a macrophage when is leaves the circulation and moves into body tissues. A neutrophil is a fully mature WBC capable of phagocytosis.

The body responds to infection by increasing the production of white blood cells (WBCs). The nurse should evaluate the differential count for what type of WBCs, which are the first WBCs to respond to an inflammatory event?

Neutrophils -Neutrophils, the most abundant type of white blood cell, are the first of the WBCs to respond to infection or inflammation. The normal value is 3,000 to 7,000/cmm (males) and 1,800 to 7,700/cmm (females).

Under normal conditions, the adult bone marrow produces approximately 70 billion neutrophils. What is the major function of neutrophils?

Phagocytosis -The major function of neutrophils is phagocytosis. T lymphocytes are responsible for rejection of foreign tissue and destruction of tumor cells. Plasma cells produce antibodies call immunoglobulin.

A nurse is assisting a client into position prior to bone marrow aspiration. Which position will the nurse place the client prior to the procedure?

Prone -Prior to the bone marrow aspiration, the nurse should place the client in either the prone position or lateral position with one leg flexed. The aspiration usually is performed on the anterior iliac crest. It would not be appropriate for the nurse to place the client in supine, knee-chest, or Trendelenburg positions.

The nurse is working at a blood donation clinic. What teaching should the nurse provide to the donor immediately after blood donation?

Remain for observation after eating and drinking.

A nurse cares for several mothers and babies in the postpartum unit. Which mother does the nurse recognize as being most at risk for a febrile nonhemolytic reaction?

Rh-negative mother; Rh-positive child -A mother who is Rh negative and gives birth to an Rh positive child is at greatest risk for a febrile nonhemolytic reaction because exposure to an Rh-positive fetus raises antibody levels in the Rh negative mother. An Rh-negative mother can carry an Rh-negative child without being at greatest risk for a febrile nonhemolytic reaction; however, these mothers are often treated prophylactically. An Rh-positive mother may carry either an Rh-positive or Rh-negative child without increased risk.

A nurse practitioner reviewed the blood work of a male client suspected of having microcytic anemia. The nurse suspected occult bleeding. Which laboratory result would indicate an initial stage of iron deficiency?

Serum ferritin: 15 ng/mL -Microcytic anemia is characterized by small RBCs due to insufficient hemoglobin. Serum ferritin levels correlate to iron deficiency and decrease as an initial response to anemia before hemoglobin and serum iron levels drop.

The nurse expects which assessment finding of the oral cavity when the client is diagnosed with pernicious anemia?

Smooth tongue -On physical assessment, the nurse expects to observe a smooth tongue in the client diagnosed with pernicious anemia. Angular cheilosis (ulceration of the corners of the mouth) is seen with anemia. Ulcerations of the oral cavity indicate infection or possible leukemia. Enlarged gums can be indicative of leukemia.

Place the following steps in order when determining the type and severity of a transfusion reaction. Use all options.

Stop the transfusion. Assess the client. Notify the health care provider. Notify the blood bank. Send the tubing and container to the blood bank.

A nurse, caring for a client with human immunodeficiency virus (HIV), reviews the client's differential WBC count. What type of WBC will the nurse check the level of?

T lymphocytes -Lymphocytes (T cells, B cells, and natural killer cells) are WBCs that are the major components of the body's immune response. T cells are primarily responsible for cell-mediated immunity, whereas B cells are involved in antibody production.

A nurse is caring for a client with a diagnosis of lymphocytopenia. Which assessment finding will the nurse consider most concerning when caring for this client?

Temperature of 37.7 degrees Celsius -Lymphocytopenia is a decrease in the number of lymphocytes. Lymphocytes help to fight foreign invaders, such as infectious organisms. A temperature of 37.7 degree Celsius is a Fahrenheit temperature of 99.9. A low-grade fewer may be indicative of an infection. The other answer choices do not suggest infection and are not the priority concern.

The nurse is administering a blood transfusion to a client over 4 hours. After 2 hours, the client reports chills and has a fever of 101°F, an increase from a previous temperature of 99.2°F. What does the nurse recognize is occurring with this client?

The client is having a febrile nonhemolytic reaction. -The signs and symptoms of a febrile nonhemolytic transfusion reaction are chills (minimal to severe) followed by fever (more than 1°C elevation). The fever typically begins within 2 hours after the transfusion is begun. Although the reaction is not life threatening, the fever, and particularly the chills and muscle stiffness, can be frightening to the client.

The nurse is caring for a client with hypoxia. What does the nurse understand is true regarding the client's oxygen level and the production of red blood cells?

The kidneys sense low oxygen levels in the blood and produce erythropoietin, stimulating the bone marrow to produce more red blood cells.

A nursing instructor is reviewing the role and function of stem cells in the bone marrow with a group of nursing students. After providing the explanation, the instructor asks the students to use their knowledge of anatomy and physiology to determine an alternate way in which adults with diseases that destroy marrow can resume production of blood cells. Which explanation by the students is correct?

The liver and spleen can resume production of blood cells through extramedullary hematopoiesis.

When administering a blood transfusion to a client with multiple traumatic injuries, the nurse monitors closely for evidence of a transfusion reaction. Shortly after the transfusion begins, the client complains of chest pain, nausea, and itching. When urticaria, tachycardia, and hypotension develop, the nurse stops the transfusion and notifies the physician. The nurse suspects which type of hypersensitivity reaction?

Type II (cytolytic, cytotoxic) hypersensitivity reaction -ABO incompatibility, such as from an incompatible blood transfusion, is a type II hypersensitivity reaction. Transfusions of more than 100 ml of incompatible blood can cause severe and permanent renal damage, circulatory shock, and even death. Drug-induced hemolytic anemia is another example of a type II reaction. A type I hypersensitivity reaction occurs in anaphylaxis, atopic diseases, and skin reactions. A type III hypersensitivity reaction occurs in Arthus reaction, serum sickness, systemic lupus erythematosus, and acute glomerulonephritis. A type IV hypersensitivity reaction occurs in tuberculosis, contact dermatitis, and transplant rejection.

While caring for a client, the nurse notes petechiae on the client's trunk and lower extremities. What precaution will the nurse take when caring for this client?

Use an electric razor when assisting client with shaving. -Petechiae are associated with severe thrombocytopenia, placing the client at risk for bleeding. The nurse should use an electric razor when assisting the client with shaving. Elevating the head of the bed and applying supplemental oxygen would be appropriate for a client with decreased oxygenation. Wearing a mask when entering the client's room would be appropriate for a client with neutropenia, not thrombocytopenia.

The client is to receive a unit of packed red blood cells. What is the nurse's first action?

Verify that the client has signed a written consent form.

Vitamin B and folic acid deficiencies are characterized by production of abnormally large erythrocytes called

megaloblasts

A client with a low red blood cell count is prescribed erythropoietin to be able to have autologous transfusion during planned joint replacement surgery. The nurse knows that which information will be important for the client to understand about this medication?

"The medication should be given by subcutaneous injection."

A patient receiving plasma develops transfusion-related acute lung injury (TRALI) 4 hours after the transfusion. What type of aggressive therapy does the nurse anticipate the patient will receive to prevent death from the injury? (Select all that apply.)

- Oxygen - Fluid support - Intubation and mechanical ventilation

Which client is not a candidate to be a blood donor according to the American Red Cross?

26-year-old female with hemoglobin 11.0 g/dL -Clients must meet a number of criteria to be eligible as blood donors, including the following: body weight at least 50 kg; pulse rate regular between 50 and 100 bpm; systolic BP 90-100 to 180 mm Hg and diastolic 50 to 100 mm Hg; hemoglobin level at least 12.5 g/dL. There is no upper age limit to donation.

A nurse is assigned to care for a patient with ascites, secondary to cirrhosis. The nurse understands that the fluid accumulation in the peritoneal cavity results from a combination of factors including an alteration in oncotic pressure gradients and increased capillary permeability. Therefore, the nurse monitors the serum level of the plasma protein responsible for maintaining oncotic pressure, which is:

Albumin. -Albumin, only produced in the liver, is essential for maintaining oncotic pressure in the vascular system. A decrease in oncotic pressure due to low albumin causes fluid to leak into the peritoneal cavity.

Which type of leukocyte contains histamine and is an important part of hypersensitivity reactions?

Basophils -Basophils contain histamine and are an integral part of hypersensitivity reactions. B lymphocytes are responsible for humoral immunity. A plasma cell secretes immunoglobulins. The neutrophil functions in preventing or limiting bacterial infection via phagocytosis.

A client is experiencing symptoms of myelodysplastic syndrome (MDS). The nurse prepare the client for which type of test to aid in diagnosing this condition?

Bone marrow aspiration and biopsy

A client with myelodysplastic syndromes (MDS) receives routine blood transfusions. Which treatment will the nurse expect to be prescribed to prevent the development of iron overload?

Chelation therapy -Iron overload is a problem for clients with MDS, especially in those who routinely receive PRBC transfusions (transfusion dependent). Surplus iron is deposited in cells within the reticuloendothelial system, and later in parenchymal organs. To prevent or reverse the complications of iron overload, iron chelation therapy is commonly implemented. Romiplostim and eltrombopag are used to stimulate the proliferation and differentiation of megakaryocytes into platelets within the bone marrow. Epoetin alpha may be used to improve anemia and decrease the need for blood transfusions.

A nursing instructor in a BSN program is preparing for a lecture on disorders of the hematopoietic system. Included in the lecture are conditions caused by reduced levels or absence of blood-clotting proteins. Which of the following is the instructor most likely referring to?

Coagulopathy -The term coagulopathy refers to conditions in which a component that is necessary to control bleeding is missing or inadequate.

The nurse is instructing the client with polycythemia vera how to perform isometric exercises such as contracting and relaxing the quadriceps and gluteal muscle during periods of inactivity. What does the nurse understand is the rationale for this type of exercise?

Contraction of skeletal muscle compresses the walls of veins and increases the circulation of venous blood as it returns to the heart.

The nurse should be alert to which adverse assessment finding when transfusing a unit of packed red blood cells (PRBCs) too rapidly?

Crackles auscultated bilaterally -Increasing the flow rate of a blood transfusion too rapidly can result in circulatory overload. Fluid overload can be manifested by crackles in the lungs. A decreased respiratory rate and decreased temperature are not manifestations of fluid overload. Pain and tenderness in the calf area may indicate a thrombosis which is not as common a manifestation as fluid overload.

A patient is undergoing platelet pheresis at the outpatient clinic. What does the nurse know is the most likely clinical disorder the patient is being treated for?

Essential thrombocythemia -Platelet pheresis is used to remove platelets from the blood in patients with extreme thrombocytosis or essential thrombocythemia (temporary measure)or in a single-donor platelet transfusion.

A client is scheduled for surgery to remove an abdominal mass. The nurse knows that which reason hemodilution would be contraindicated as a method to provide blood to the client during the surgery?

History of renal disease -Hemodilution is the removal of 1 to 2 units of blood after induction of anesthesia and replaced with a colloid or crystalloid solution. The blood is then reinfused after the surgery. The purpose of this approach is to reduce the amount of erythrocytes lost during the surgery because the intravenous fluids dilute the concentration of red blood cells and lowers the hematocrit. Hemodilution has been linked to tissue ischemia in the kidneys and would be contraindicated in the client with a history of renal disease. Hemodilution would not be contraindicated for a previous thyroidectomy, treatment for osteoarthritis, or medication used to treat seasonal allergies.

The nurse is caring for a client who has a unit of whole blood removed every 6 weeks as treatment for polycythemia vera. Which laboratory test will the nurse monitor to determine if the procedure is adversely affecting the client?

Iron -Therapeutic phlebotomy is the removal of a certain amount of blood under controlled conditions. A client with an elevated hematocrit from polycythemia vera can usually be managed by periodically removing 1 unit (about 500 mL) of whole blood. Over time, this process can produce iron deficiency, Therapeutic phlebotomy does not affect the calcium or potassium levels or the white blood cell count.

The client's CBC with differential reveals small-shaped hemoglobin molecules. The nurse expects to administer which medication to this client?

Iron -With iron deficiency, the erythrocytes produced by the marrow are small and low in hemoglobin. Vitamin B12 and folate deficiencies are characterized by the production of abnormally large erythrocytes. Fresh frozen plasma are infused due to a low platelet level, not light-colored hemoglobin.

Which type of lymphocyte is responsible for cellular immunity?

T lymphocyte -T lymphocytes are responsible for delayed allergic reactions, rejection of foreign tissue (e.g., transplanted organs), and destruction of tumor cells. This process is known as cellular immunity. B lymphocytes are responsible for humoral immunity. A plasma cell secretes immunoglobulin. A basophil contains histamine and is an integral part of hypersensitivity reactions.

A client comes into the emergency department reporting an enlarged tongue. The tongue appears smooth and beefy red in color. The nurse also observes a 5-cm incision on the upper left quadrant of the abdomen. When questioned, the client states, "I had a partial gastrostomy 2 years ago." Based on this information, the nurse attributes these symptoms to which problem?

Vitamin B12 deficiency -Because vitamin B12 is found only in foods of animal origin, strict vegetarians may ingest little vitamin B12. Vitamin B12 combines with intrinsic factor produced in the stomach. The vitamin B12-intrinsic factor complex is absorbed in the distal ileum. Clients who have had a partial or total gastrectomy may have limited amounts of intrinsic factor, and therefore the absorption of vitamin B12 may be diminished. The effects of either decreased absorption or decreased intake of vitamin B12 are not apparent for 2-4 years. This results in megaloblastic anemia. Some symptoms are a smooth, beefy red, enlarged tongue and cranial nerve deficiencies.

The nurse is obtaining the health history of a client suspected of having a hematological condition. The nurse notes the client has a history of alcohol abuse. Which clinical presentation is related to alcohol consumption?

Anemia -Individuals with a history of alcohol consumption may have anemia due to nutritional deficiencies. Myelodysplastic syndrome, neutropenia, and thrombocytopenia are not common findings in clients who consume or abuse alcohol.

Which of the following cells are capable of differentiating into plasma cells?

B lymphocytes -B lymphocytes are capable of differentiating into plasma cells. Plasma cells, in turn, produce antibodies called immunoglobulins (Ig), which are protein molecules that destroy foreign material by several mechanisms. T lymphocytes, eosinophils, and neutrophils do not differentiate into plasma cells.

Post transfusion, the donor stands up immediately after the needle is withdrawn. The nurse should be alert for which vital sign change?

Decreased blood pressure. -Because of the loss of blood volume, hypotension and syncope may occur when the donor assumes an erect position. The most likely vital sign change is decreased blood pressure. The respiratory rate and temperature should not be affected by a change in position. With hypotension and decreased blood volume, the pulse would increase, not decrease.

A patient will need a blood transfusion for the replacement of blood loss from the gastrointestinal tract. The patient states, "That stuff isn't safe!" What is the best response from the nurse?

"I understand your concern. The blood is carefully screened but is not completely risk free." -Despite advances in donor screening and blood testing, certain diseases can still be transmitted by transfusion of blood components

A nurse is teaching a client with a vitamin B12 deficiency about appropriate food choices to increase the amount of B12 ingested with each meal. The nurse knows the teaching is effective based on which statement by the client?

"I will eat a meat source such as chicken or pork with each meal." -Vitamin B12 is found only in foods of animal origin. The other choices do not include meats. Dairy products contain large amounts of Calcium and vitamin D. Orange vegetables contain large amounts of vitamin A.

A nurse cares for a client with megaloblastic anemia who had a total gastrectomy three years ago. What statement will the nurse include in the client's teaching regarding the condition?

"The condition is likely caused by a vitamin B12 deficiency." -Vitamin B12 combines with intrinsic factor produced in the stomach. The vitamin B12 -intrinsic factor complex is absorbed in the distal ileum. Clients who have had a partial or total gastrectomy may have limited amounts of intrinsic factor, and the absorption of vitamin B12 may be diminished. Megaloblastic anemia may be caused by a folate deficiency; however, the client's history of gastrectomy indicates the likely cause is a vitamin B12 deficiency. Megaloblastic anemia causes large erythrocytes (RBCs), not small or rigid.

A client receiving a blood transfusion reports shortness of breath, appears anxious, and has a pulse of 125 beats/minute. What is the best action for the nurse to take after stopping the transfusion and awaiting further instruction from the health care provider?

Ensure there is an oxygen delivery device at the bedside. -The client is exhibiting signs of circulatory overload. After stopping the transfusion and notifying the healthcare provider, the nurse should place the client in a more upright position with the legs dependent to decrease workload on the heart. The IV line is kept patent in case emergency medications are needed. Oxygen and morphine may be needed to treat severe dyspnea. Administering an anti-anxiety agent is not a priority action over ensuring oxygen is available.

The nurse cares for a client with a coagulation factor deficiency who is actively bleeding. Which blood component replacement does the nurse anticipate administering?

FFP -Fresh frozen plasma has all the coagulation factors in it and is the blood component replacement therapy that will be used to replace blood from a client who is actively bleeding with a coagulation factor deficiency.

A patient who has long-term packed RBC (PRBC) transfusions has developed symptoms of iron toxicity that affect liver function. What immediate treatment should the nurse anticipate preparing the patient for that can help prevent organ damage?

Iron chelation therapy -Iron overload is a complication unique to people who have had long-term PRBC transfusions. One unit of PRBCs contains 250 mg of iron. Patients with chronic transfusion requirements can quickly acquire more iron than they can use, leading to iron overload. Over time, the excess iron deposits in body tissues and can cause organ damage, particularly in the liver, heart, testes, and pancreas. Promptly initiating a program of iron chelation therapy can prevent end-organ damage from iron toxicity.

A client reports feeling faint after donating blood. What is the nurse's best action?

Keep client in recumbent position to rest. -After blood donation, the donor should remain recumbent until he or she feels able to sit up. Donors who experience weakness or faintness should rest for a longer period. High-Fowler's position would not promote blood flow to the brain, and could cause the client to feel light-headed or faint. Ambulating a client who feels faint is not safe due to the high risk of falling. Trendelenburg position is not recommended after blood donation.

The nurse is providing health education to an older adult client who has low red blood cell levels. To promote red blood cell production, the nurse should encourage intake of what foods? Select all that apply.

- Leafy green vegetables - Lean meats - Nuts and seeds

What does the nurse recognize as secondary sites of hematopoiesis that is unique to embryonic development? Select all that apply.

- Liver - Spleen

A client's electronic health record states that the client receives regular transfusions of factor IX. The nurse would be justified in suspecting that this client has what diagnosis?

Hemophilia -Administration of clotting factors is used to treat diseases where these factors are absent or insufficient; hemophilia is among the most common of these diseases. Factor IX is not used in the treatment of leukemia, lymphoma, or anemia.

Which blood cell type is matched correctly with its function?

Leukocyte: Fights infection -Various blood cell types have unique, major functions. Leukocytes fight infection, T lymphocytes are integral in cell-mediated immunity, plasma cells secrete immunoglobulin, and B lymphocytes are integral in humoral immunity.

Which nursing intervention should be incorporated into the plan of care for a client with impaired liver function and a low albumin concentration?

Monitor for edema at least once per shift -Albumin is particularly important for the maintenance of fluid balance within the vascular system. Capillary walls are impermeable to albumin, so its presence in the plasma creates an osmotic force that keeps fluid within the vascular space. Clients with impaired hepatic function may have low concentrations of albumin, with a resultant decrease in osmotic pressure and the development of edema.
