Chapter 30 : Introduction to the Hematopoietic and Lymphatic Systems Questions
Question 1 of 5
A client is admitted to the emergency department with significant blood loss. The physician prescribes 2 units of packed red blood cells to be transfused immediately. Which blood groups would be compatible with his O Rh-positive blood group?
Correct Answer: A
Rationale: 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 non-self, 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.
Question 2 of 5
The nurse is caring for a client who is undergoing bone marrow aspiration to determine the blood cell formation status. What nursing intervention should the nurse provide to the client during the test?
Correct Answer: D
Rationale: When a client undergoes a bone marrow aspiration, the nurse assists the physician, supports the client during the procedure, and monitors the condition afterward. The client needs to be administered oral radioactive vitamin Bâ??â?? or a nonradioactive Bâ??â?? 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 Bâ??â?? is also applicable to the Schilling test.
Question 3 of 5
A nurse is providing care to a cancer client. Which protein in plasma functions primarily as immunologic agents?
Correct Answer: A
Rationale: 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. The other options are incorrect.
Question 4 of 5
A client's family member asks what hematopoiesis is. What should the nurse tell the family member?
Correct Answer: A
Rationale: 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.
Question 5 of 5
The nursing instructor is teaching her clinical group about laboratory blood tests. What is the major function of erythrocytes?
Correct Answer: C
Rationale: Erythrocytes (or RBCs) are flexible, anuclear (lacking a nucleus), biconcave disks covered by a thin membrane through which oxygen (Oâ??) and carbon dioxide (COâ??) pass freely. The flexibility of erythrocytes allows them to change shape as they travel through capillaries. Their major function is to transport Oâ?? to and remove COâ?? from the tissues. The RBCs are not involved in immunological functions, so choices A and B are not correct. Oxygenation of the brain is important but that is not a major function of RBCs.
