Exam 16: Hematological and Immune Disorders

The process by which the body actively produces cells and mediators that result in the destruction of the antigen is called:

A reduction in the number of circulating RBCs or hemoglobin,which leads to inadequate oxygenation of tissues,is known as:

The ratio of helper T4 cell to suppressor T cells is normally 2:1.A lower than normal ratio may indicate acquired immunodeficiency syndrome (AIDS).This is because T4 cells:

Exudate formation at the inflammatory site functions to: (Select all that apply.)

Two types of specific immune responses exist: humoral immunity and cell-mediated immunity.These responses:

With minor vessel injury,primary hemostasis is achieved:

The patient is being seen for complaints of general malaise,fatigue,and shortness of breath.The patient states that he has felt this way since he had a cold 6 weeks earlier.The nurse should expect the provider to order:

The nurse is caring for a patient with cirrhosis of the liver.The nurse notes fresh blood starting to ooze from the patient's rectum and intravenous site.The nurse contacts the provider expecting an order for:

The patient is admitted for chemotherapy,but the nurse notices laboratory values indicating that the patient is immunosuppressed.The nurse should:

The mechanism responsible for the rejection of transplanted tissue and the destruction of single malignant cells is known as immunosurveillance.The nurse understands that this is a function of:

When examining the patient's laboratory values,the nurse notices an elevation in the eosinophil count.The nurse realizes that eosinophils become elevated:

The patient is admitted with neutropenia.The nurse should continually assess the patient for:

The patient is complaining of severe joint pain as well as fatigue and shortness of breath.The nurse notices that the patient's joints are swollen and his legs are edematous.The nurse realizes that these are symptoms of:

The patient's platelet count is 35,000/microliter.The provider orders the administration of 10 units of single-donor platelets.After transfusion,the nurse can expect the patient's platelet count to be:

Erythrocytes (RBCs)are generated from precursor stem cells under the influence of a growth factor called:

The nurse is evaluating the patient's laboratory values and notes an IgG level of 240 mg/dL.The nurse realizes that this patient is a candidate for:

Causes of anemia include: (Select all that apply.)

The nurse examines the patient's complete blood count with differential analysis and notices that the patient's neutrophils are elevated,but the lymphocytes are lower than normal.The drop in lymphocyte count in the differential is most likely due to:

The patient has yellow skin and low hemoglobin and hematocrit levels.The nurse should look for:

The patient's white blood cell ( WBC )level is 4000 cells/microliter.The differential shows a neutrophil count of 65% and a band level of 5%.The absolute neutrophil count is
