Lewis Chapter 32: Hematological System Flashcards
Why might a client who lives at a high altitude normally have an increased RBC count?
a. High altitudes cause vascular fluid loss, leading to hemoconcentration.
b. Hypoxia caused by decreased atmospheric oxygen stimulates erythropoiesis.
c. The function of the spleen in removing old erythrocytes is impaired at high altitudes.
d. Impaired production of leukocytes and platelets leads to proportionally higher RBC counts.
B.
What is the primary effect of malignant disorders that arise from granulocytic cells in the bone marrow?
a. Risk for hemorrhage
b. Altered oxygenation
c. Decreased production of antibodies
d. Decreased phagocytosis of bacteria
D.
An anticoagulant such as warfarin that interferes with prothrombin production will alter the clotting mechanism during what process?
a. Platelet aggregation
b. Activation of thrombin
c. Release of tissue thromboplastin
d. Stimulation of factor activation complex
B.
When reviewing laboratory results of an 83-year-old client with an infection, what should the nurse expect to find?
a. Minimal leukocytosis
b. Decreased platelet count
c. Increased hemoglobin and hematocrit levels
d. Decreased erythrocyte sedimentation rate (ESR)
A.
What significant information related to the hematological system should be obtained from a client’s health history?
a. Jaundice
b. Bladder surgery
c. Early menopause
d. Tonsillectomy
A.
What technique should the nurse use when assessing the lymph nodes?
a. Applying gentle, firm pressure to deep lymph nodes
b. Palpating the deep cervical and supraclavicular nodes last
c. Lightly palpating superficial lymph nodes with the pads of the fingers
d. Using the tips of the second, third, and fourth fingers to apply deep palpation
C.
When a lymph node is palpated, which of the following is a normal finding?
a. Hard, fixed nodes
b. Firm, mobile nodes
c. Enlarged, tender nodes
d. Hard, nontender nodes
B.
Nursing care for a client immediately after a bone marrow biopsy and aspiration includes which of the following? (Select all that apply.)
a. Administering analgesics as necessary
b. Preparing to administer a blood transfusion
c. Instructing on the need to lie still with a sterile pressure dressing intact
d. Monitoring vital signs and assessing the site for excess drainage or bleeding
e. Instructing on the need for preprocedure and postprocedure antibiotics
A,C,D.
A nurse is taking care of a male client who has the following laboratory values from his CBC: WBC 6.5×109/L, Hb 134 g/L, Hct 40%, platelets 50×109/L. What should the nurse be most concerned about?
a. The client is neutropenic.
b. The client has an infection.
c. The client is at risk for bleeding.
d. The client is at risk of falling due to his anemia.
C.
Which hematological history includes the assessment of alcohol and illicit drug use?
A. Social and occupational history
B. Activities of daily living
C. Neurological history
D. Self-care history
D. Self-care history
The self-care history includes assessing for alcohol, illicit drug, or cigarette use in partial completion of the hematological history.
Which lymph node assessment finding is abnormal?
A. Fixed (not moveable)
B. Size 0.5 cm
C. Nontender
D. Firm texture
A. Fixed (not moveable)
A fixed lymph node is considered an abnormal finding. A normal lymph node is movable on palpation.
Which skin assessment finding is indicative of a bleeding disorder? Select all that apply. One, some, or all responses may be correct.
A. Petechiae
B. Purpura
C. Digit clubbing
D. Ecchymosis
E. Spider nevus
A, B, D, E.
Signs of bleeding disorders found in the skin assessment include petechiae, purpura, ecchymosis, and spider nevus.
Which laboratory value is a measure of the packed cell volume of red blood cells (RBCs) expressed as a percentage of the total blood volume?
A. Platelet count
B. Hematocrit
C. Reticulocyte count
D. White blood cell (WBC) count
B. Hematocrit
Hematocrit is a measurement of packed cell volume of RBCs and is expressed as a percentage of the total blood volume.
Which red blood cell (RBC) test is increased in the event of hemoconcentration?
A. White blood cells
B. RBC indices
C. Hemoglobin
D. Prothrombin time
C. Hemoglobin
Hemoglobin is increased in the case of polycythemia and hemoconcentration.
Which blood test is needed to reduce transfusion reaction prior to a blood transfusion? Select all that apply. One, some, or all responses may be correct.
A. Screen
B. Bilirubin
C. Crossmatch
D. Group
E. Blood smear
A, C, D.
The group, screen, and crossmatch are completed before a blood transfusion to minimize transfusion reaction.
