1.You are caring for three clients who have the following blood count values: Client A has
24,500/mm3 white blood cells (WBCs), client B has 13.4 g/dL hemoglobin, and client C
has a 250,000/mm3 platelet count. Which statement correctly describes the condition of
each client?
A) Client A has a normal WBC count, client B has a higher hemoglobin count than
normal, and client C has a normal platelet count.
B) Client A has a higher WBC count than normal, client B has a normal hemoglobin
count, and client C has a normal platelet count.
C) Client A has a higher WBC count than normal, client B has a normal hemoglobin
count, and client C has a higher platelet count than normal.
D) Client A has a normal WBC count than normal, client B has a normal hemoglobin
count, and client C has a normal platelet count.
Ans: B
Feedback:
The normal leukocyte count is between 5000 and 10,000/mm3. Client A has an increased
number of leukocytes greater than 10,000/mm3 and hence has leukocytosis. In adults, the
normal amount of hemoglobin is 12.0 to 17.4 g/dL; therefore, client B has a normal
hemoglobin count. A normal circulating platelet count is 150,000 to 350,000/mm3
platelets; therefore, client C has a normal platelet count.
2.A client is admitted to the emergency department with significant blood loss. The
physician orders 2 units of packed red blood cells to be transfused immediately. Which
blood groups would be compatible with his O Rh-positive blood group?
A) O Rh-positive or O Rh-negative
B) Only O Rh-positive
C) Only O Rh-negative
D) AB Rh-positive or Rh-negative
Ans: A
Feedback:
People with Rh-positive blood can receive Rh-positive or Rh-negative blood because a
negative Rh indicates a missing Rh factor. Antibodies, immunoglobulins in plasma that
inactivate any substance that is nonself, react with incompatible red blood cell antigens.
Therefore, people with type O blood are universal donors because they do not have
antigens on the red cell membrane. Therefore, the client can be transfused with either O
Rh-positive or O Rh-negative blood.
3.You are caring for a client who is undergoing bone marrow aspiration to determine the
blood cell formation status. What nursing intervention should you provide to your client
during the test?
A) Administer oral radioactive vitamin B12 to the client.
B) Administer a nonradioactive B12 injection.
C) Collect urine for 24 to 48 hours after the client receives the nonradioactive B12.
D) Support the client and monitor the status.
Ans: D
Page 1
, Feedback:
When a client undergoes a bone marrow aspiration, the nurse assists the physician,
supports the client during the procedure, and monitors his or her condition afterward. The
client needs to be administered oral radioactive vitamin B12 or a nonradioactive B12
injection in case of the Schilling test, which helps in determining pernicious anemia and
macrocytic anemia. Collecting urine for 24 to 48 hours after administering nonradioactive
B12 is also applicable to the Schilling test.
4.A nurse is providing care to a cancer patient. Which protein in plasma functions primarily
as immunologic agents?
A) Gamma globulins
B) Albumin
C) Fibrinogen
D) Beta globulins
Ans: A
Feedback:
Globulins are divided into three groups: alpha, beta, and gamma. The gamma globulins
are also called immunoglobulins. Globulins function primarily as immunologic agents;
they prevent or modify some types of infectious diseases. Therefore options B, C, and D
are incorrect.
5.A patient's family member asks what hematopoiesis is. What should the nurse tell the
family member?
A) The manufacture and development of blood cells
B) The production of lymphatic fluid in the body
C) The making of red blood cells and lymph
D) The development of lymph in the bone marrow
Ans: A
Feedback:
Hematopoiesis is the manufacture and development of blood cells. It also considers the
lymphatic system, which includes the thymus gland and spleen; this system assists in the
maturation of certain lymphocytes. Hematopoiesis is not the production of lymphatic
fluid or the development of lymph in the bone marrow.
6.The nursing instructor is teaching her clinical group about laboratory blood tests. What is
the major function of erythrocytes?
A) Act as mediators for the immune system
B) Destroy invading organisms
C) Transportation of O2 to the tissues and removal of CO2 from the tissues
D) Oxygenation of the brain
Ans: C
Feedback:
Erythrocytes (or RBCs) are flexible, anuclear (lacking a nucleus), biconcave disks
