2024 Hematology – NCLEX VERIFIED QUESTIONS 100% CORRECT ANSWERS

In a severely anemic patient, you expect to find A. dyspnea and tachycardia. B. cyanosis and pulmonary edema. C. cardiomegaly and pulmonary fibrosis. D. ventricular dysrhythmias and wheezing. - CORRECT ANSWER A. dyspnea and tachycardia. Patients with severe anemia (hemoglobin 6 g/dL) exhibit the following cardiovascular and pulmonary manifestations: tachycardia, increased pulse pressure, systolic murmurs, intermittent claudication, angina, heart failure, myocardial infarction; tachypnea, orthopnea, dyspnea at rest. When obtaining assessment data from a patient with a microcytic, hypochromic anemia, you question the patient about A. folic acid intake. B. dietary intake of iron. C. a history of gastric surgery. D. a history of sickle cell anemia. - CORRECT ANSWER B. dietary intake of iron. Iron deficiency anemia is a type of microcytic, hypochromic anemia. When caring for a patient with metastatic cancer, you note a hemoglobin level of 8.7 g/dL and hematocrit of 26%. You place highest priority on initiating interventions that can reduce A. thirst. B. fatigue. C. headache. D. abdominal pain. - CORRECT ANSWER B. fatigue. The patient with a low hemoglobin level and hematocrit is anemic and is most likely to experience fatigue. Fatigue develops because of the lowered oxygen-carrying capacity that leads to reduced tissue oxygenation with which to carry out cellular functions. You are caring for a patient with a diagnosis of iron-deficiency anemia. Which clinical manifestations are you most likely to observe when assessing this patient? A. Convex nails, bright red gums, and alopecia B. Brittle nails; smooth, shiny tongue; and cheilosis C. Tenting of the skin, sunken eyes, and complaints of diarrhea D. Pale pink tongue; dull, brittle hair; and blue mucous membranes - CORRECT ANSWER B. Brittle nails; smooth, shiny tongue; and cheilosis Specific clinical manifestations may be related to iron-deficiency anemia. Pallor is the most common finding, and glossitis (inflammation of the tongue) is the second most common; another finding is cheilitis (inflammation of the lips). The patient may report headache, paresthesias, and a burning sensation of the tongue, all of which are caused by lack of iron in the tissues. When providing teaching for the patient with iron-deficiency anemia who has been prescribed iron supplements, you should include taking the iron with which beverage? A. Milk B. Ginger ale C. Orange juice D. Water - CORRECT ANSWER C. Orange juice Taking iron with vitamin C (ascorbic acid) or orange juice, which contains ascorbic acid, also enhances iron absorption. Milk may interfere with iron absorption. Ginger ale and water do not facilitate iron absorption. The primary pathophysiology underlying thalassemia is A. erythropoietin deficiency. B. abnormal hemoglobin synthesis. C. autoimmunity. D. S-shaped hemoglobin. - CORRECT ANSWER B. abnormal hemoglobin synthesis. Thalassemia is a group of autosomal recessive diseases that involve inadequate production of normal hemoglobin. Hemolysis also occurs in thalassemia, but insufficient production of normal hemoglobin is the predominant problem. Erythropoietin deficiency is associated with a renal disorder, and S-shaped hemoglobin is associated with sickle cell disease. You anticipate the onset of manifestations related to thalessemia to occur by A. 6 months of age. B. age 1 year. C. age 2 year. D. adolescence. - CORRECT ANSWER C. age 2 year. The manifestations, including growth and developmental deficits, develop in childhood by 2 years of age. Which individual is at high risk for a cobalamin (vitamin B12) deficiency anemia? A. A 47-year-old man who had a gastrectomy (removal of the stomach) B. A 54-year-old man with a history of irritable bowel disease and ulcerative colitis C. A 26-year-old woman who complains of heavy menstrual periods D. A 15-year-old girl who is a vegetarian - CORRECT ANSWER A. A 47-year-old man who had a gastrectomy (removal of the stomach) There are many causes of cobalamin deficiency. The most common cause is pernicious anemia, a disease in which the gastric mucosa is not secreting intrinsic factor (IF) because of antibodies being directed against the gastric parietal cells or IF itself. Other causes of cobalamin deficiency include gastrectomy, gastritis, nutritional deficiency, chronic alcoholism, and hereditary enzymatic defects of cobalamin use. You encourage the patient with cobalamin deficiency to seek treatment because untreated pernicious anemia may result in A. death. B. liver failure. C. heart failure. D. gastrectomy. - CORRECT ANSWER A. death. Without cobalamin administration, these individuals will die in 1 to 3 years. The Schilling test for pernicious anemia involves A. administration of radioactive cobalamin and measuring its excretion in the urine. B. blood cultures for organism identification. C. the measurement of serum iron. D. the administration of iron and blood assessment of total iron binding in 24 hours. - CORRECT ANSWER A. administration of radioactive cobalamin and measuring its excretion in the urine. Parietal cell function can be assssed with a Schilling test. After radioactive cobalamin is administered to the patient, the amount of cobalamin excreted in the urine is measured. An individual who cannot absorb cobalamin excretes only a small amount of this radioactive form. Which finding allows you to identify the patient's anemia as folic acid deficiency rather than cobalamin deficiency? A. Loss of appetite B. Lack of neuromuscular symptoms C. Red tongue D. Change in nail shape - CORRECT ANSWER B. Lack of neuromuscular symptoms The absence of neurologic problems is an important diagnostic finding and differentiates folic acid deficiency from cobalamin deficiency. Which foods should you encourage patients with folic acid deficiency to include in their daily food intake (select all that apply)? A. Ready-to-eat cereal B. Wheat tortillas C. Lentils D. Strawberries E. Potatoes - CORRECT ANSWER A. Ready-to-eat cereal B. Wheat tortillas C. Lentils
