HEMO: Lewis Ch 30 Hematologic Problems Flashcards
An adult male with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. Which laboratory data would the nurse identify as consistent with these symptoms?
a. RBC count of 4,500,000/L
b. Hematocrit (Hct) value of 38%
c. Normal red blood cell (RBC) indices
d. Hemoglobin (Hgb) of 8.6 g/dL (86 g/L)
d. Hemoglobin (Hgb) of 8.6 g/dL (86 g/L)
The patient’s symptoms indicate moderate anemia, which is consistent with a Hgb of 6 to 10 g/dL. The other values are all within the range of normal.
Which menu choice indicates that the patient understands the nurse’s recommendations about dietary choices for iron-deficiency anemia?
a. Omelet and whole wheat toast
b. Cantaloupe and cottage cheese
c. Strawberry and banana fruit plate
d. Cornmeal muffin and orange juice
a. Omelet and whole wheat toast
Eggs and whole grain breads are high in iron. The other choices are appropriate for other nutritional deficiencies but are not the best choice for a patient with iron-deficiency anemia.
A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. Which nutrient supplement should the nurse plan to explain to the patient?
a. Iron
b. Folic acid
c. Cobalamin (vitamin B12)
d. Ascorbic acid (vitamin C)
b. Folic acid
Methotrexate use can lead to folic acid deficiency. Supplementation with oral folic acid supplements is the usual treatment. The other nutrients would not correct folic acid deficiency, although they would be used to treat other types of anemia.
Which patient statement to the nurse indicates that the patient understands self-care for pernicious anemia?
a. “I need to start eating more red meat and liver.”
b. “I will stop having a glass of wine with dinner.”
c. “I could choose nasal spray rather than injections of vitamin B12.”
d. “I will need to take a proton pump inhibitor such as omeprazole (Prilosec).”
c. “I could choose nasal spray rather than injections of vitamin B12.”
Because pernicious anemia prevents the absorption of vitamin B12, this patient requires injections or intranasal administration of cobalamin. Alcohol use does not cause cobalamin deficiency. Proton pump inhibitors decrease the absorption of vitamin B12. Eating more foods rich in vitamin B12 is not helpful because the lack of intrinsic factor prevents absorption of the vitamin.
Which is an appropriate nursing intervention for a hospitalized patient with severe hemolytic anemia?
a. Provide a diet high in vitamin K.
b. Teach the patient how to avoid injury.
c. Encourage alternating rest and activity.
d. Place the patient on protective isolation.
c. Encourage alternating rest and activity.
Nursing care for patients with anemia should alternate periods of rest and activity to avoid
undue fatigue. There is no indication that the patient has a bleeding disorder, so a diet high in
vitamin K or teaching about how to avoid injury is not needed. Protective isolation might be used for a patient with aplastic anemia, but it is not indicated for hemolytic anemia.
Which patient statement to the nurse indicates a need for additional instruction about taking oral ferrous sulfate?
a. “I could take a stool softener if I feel constipated.”
b. “I can take the iron with orange juice before eating.”
c. “I should notify my health care provider if my stools turn black.”
d. “I will increase my fluid and fiber intake while I am taking iron.”
c. “I should notify my health care provider if my stools turn black.”
It is normal for the stools to appear black when a patient is taking iron, and the patient should not call the health care provider about this. The other patient statements are correct.
Which potential complication should the nurse identify as a high risk for a patient admitted to the hospital with idiopathic aplastic anemia?
a. Seizures
b. Infection
c. Neurogenic shock
d. Pulmonary edema
b. Infection
Because the patient with aplastic anemia has pancytopenia, the patient is at risk for infection and bleeding. There is no increased risk for seizures, neurogenic shock, or pulmonary edema.
Which nursing intervention is important when providing care for a patient with sickle cell crisis?
a. Limiting the patient’s intake of oral and IV fluids
b. Evaluating the effectiveness of opioid analgesics
c. Encouraging the patient to ambulate as much as tolerated
d. Teaching the patient about high-protein, high-calorie foods
b. Evaluating the effectiveness of opioid analgesics
Pain is the most common clinical manifestation of a crisis and usually requires large doses of continuous opioids for control. Fluid intake should be increased to reduce blood viscosity and improve perfusion. Rest is usually ordered to decrease metabolic requirements. Patients are instructed about the need for dietary folic acid, but high-protein, high-calorie diets are not emphasized.
Which statement by a patient indicates good understanding of the nurse’s teaching about preventing sickle cell crisis?
a. “Home oxygen therapy is frequently used to decrease sickling.”
b. “There are no effective medications that can help prevent sickling.”
c. “Routine continuous dosage opioids are prescribed to prevent a crisis.”
d. “Risk for a crisis is decreased by having an annual influenza vaccination.”
d. “Risk for a crisis is decreased by having an annual influenza vaccination.”
Because infection is the most common cause of a sickle cell crisis, influenza, Haemophilus influenzae, pneumococcal pneumonia, and hepatitis immunizations should be administered. Although continuous dose opioids and oxygen may be administered during a crisis, patients do not receive these therapies to prevent crisis. Hydroxyurea (Hydrea) is a medication used to decrease the number of sickle cell crises.
Which instruction will the nurse plan to include in discharge teaching for a patient admitted with a sickle cell crisis?
a. Limit fluids to 2 to 3 quarts per day.
b. Avoid exposure to crowds when possible.
c. Take a daily multivitamin supplement with iron.
d. Drink no more than two caffeinated beverages daily.
b. Avoid exposure to crowds when possible.
Exposure to crowds increases the patient’s risk for infection, the most common cause of sickle cell crisis. There is no restriction on caffeine use. Iron supplementation is generally not recommended. A high-fluid intake is recommended.
The nurse observes scleral jaundice in a patient being admitted with hemolytic anemia. Which laboratory result the nurse should check?
a. Schilling test
b. Bilirubin level
c. Stool occult blood
d. Gastric acid analysis
b. Bilirubin level
Jaundice is caused by the elevation of bilirubin level associated with red blood cell hemolysis. Other tests would not be helpful in monitoring hemolytic anemia.
A patient who has been receiving IV heparin infusion and oral warfarin (Coumadin) for a deep vein thrombosis (DVT) is diagnosed with heparin-induced thrombocytopenia (HIT) when the platelet level drops to 110,000/μL. Which action will the nurse include in the plan of care?
a. Prepare for platelet transfusion.
b. Discontinue the heparin infusion.
c. Administer prescribed warfarin (Coiumadin).
d. Give low-molecular-weight heparin (LMWH).
b. Discontinue the heparin infusion.
All heparin is discontinued when HIT is diagnosed. The patient should be instructed to never receive heparin or LMWH. Warfarin is usually not given until the platelet count has returned to 150,000/μL. The platelet count does not drop low enough in HIT for a platelet transfusion, and platelet transfusions increase the risk for thrombosis.
What action is expected by the nurse caring for a patient who has an acute exacerbation of polycythemia vera?
a. Place the patient on bed rest.
b. Administer iron supplements.
c. Avoid use of aspirin products.
d. Monitor fluid intake and output.
d. Monitor fluid intake and output.
Monitoring hydration status is important during an acute exacerbation because the patient is at risk for fluid overload or underhydration. Aspirin therapy is used to decrease risk for thrombosis. The patient should be encouraged to ambulate to prevent deep vein thrombosis. Iron is contraindicated in patients with polycythemia vera.
Which intervention will be included in the nursing care plan for a patient with immune thrombocytopenic purpura?
a. Assign the patient to a private room.
b. Avoid intramuscular (IM) injections.
c. Use rinses rather than a soft toothbrush for oral care.
d. Restrict activity to passive and active range of motion.
b. Avoid intramuscular (IM) injections.
IM or subcutaneous injections should be avoided because of the risk for bleeding. A soft toothbrush can be used for oral care. There is no need to restrict activity or place the patient in a private room.
Which laboratory result will the nurse expect to show a decreased value if a patient develops heparin-induced thrombocytopenia (HIT)?
a. Prothrombin time
b. Erythrocyte count
c. Fibrinogen degradation products
d. Activated partial thromboplastin time
d. Activated partial thromboplastin time
Platelet aggregation in HIT causes neutralization of heparin, so the activated partial thromboplastin time will be shorter, and more heparin will be needed to maintain therapeutic levels. The other data will not be affected by HIT.
The nurse is caring for a patient with type A hemophilia being admitted to the hospital with severe pain and swelling in the right knee. Which action should the nurse take?
a. Apply heat to the knee.
b. Immobilize the knee joint.
c. Assist the patient with light weight bearing.
d. Perform passive range of motion to the knee.
b. Immobilize the knee joint.
The initial action should be total rest of the knee to minimize bleeding. Ice packs are used to decrease bleeding. Range of motion (ROM) and weight-bearing exercise are contraindicated initially, but after the bleeding stops, ROM and physical therapy are started.
A young adult who has von Willebrand disease is admitted to the hospital for minor knee surgery. Which laboratory value should the nurse monitor?
a. Platelet count
b. Bleeding time
c. Thrombin time
d. Prothrombin time
b. Bleeding time
The bleeding time is affected by von Willebrand disease. Platelet count, prothrombin time, and thrombin time are normal in von Willebrand disease.
A routine complete blood count for an active older man indicates possible myelodysplastic syndrome. What should the nurse plan to explain to the patient?
a. Blood transfusion
b. Bone marrow biopsy
c. Filgrastim administration
d. Erythropoietin administration
b. Bone marrow biopsy
Bone marrow biopsy is needed to make the diagnosis and determine the specific type of myelodysplastic syndrome. The other treatments may be necessary later if there is progression of the myelodysplastic syndrome, but the initial action for this asymptomatic patient will be a bone marrow biopsy.
Which action will the admitting nurse include in the care plan for a patient who has
neutropenia?
a. Avoid intramuscular injections.
b. Check temperature every 4 hours.
c. Place a “No Visitors” sign on the door.
d. Omit fruits and vegetables from the diet.
b. Check temperature every 4 hours.
The earliest sign of infection in a neutropenic patient is an elevation in temperature. While unpeeled fresh fruits and vegetables should be avoided, fruits and vegetables that are peeled or cooked are acceptable. Injections may be required for administration of medications such as filgrastim (Neupogen). The number of visitors may be limited and visitors with communicable diseases should be avoided, but a “no visitors” policy is not needed.
