A client'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
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.

Albumin is a protein in the plasma portion of the blood. Under normal conditions, albumin cannot pass through the wall of a capillary. What significance is this for the vascular compartment?
- A. Helps push oxygen into the tissues of the body
- B. Retains leukocytes in the vascular compartment
- C. Helps retain fluid in the vascular compartment
- D. Absorbs carbon dioxide from the tissues for transport to the lungs
Correct Answer: C
Rationale: Under normal conditions, albumin cannot pass through a capillary wall. Consequently, albumin helps maintain the osmotic pressure that retains fluid in the vascular compartment. Albumin does not push oxygen into the tissues of the body or absorb carbon dioxide for transport to the lungs. Albumin also does not retain leukocytes in the vascular compartment.
A client is in the hospital with a bleeding gastric ulcer and requires a blood transfusion. He has been typed and crossmatched for 2 units of packed red blood cells and found to have type O blood. What type of blood will the nurse administer to this client?
- A. Type A
- B. Type B
- C. Type AB
- D. Type O
Correct Answer: D
Rationale: Those with type O blood can only receive type O blood. Clients with all other blood types can receive type O blood provided the Rh factor is compatible.
A client has type AB blood. What type of blood must this client receive during a blood transfusion?
- A. They can receive blood from persons with any type of blood if the RH factor is compatible.
- B. They can only receive blood from persons with type A blood.
- C. They can only receive blood from persons with type B blood.
- D. They can only receive blood from persons with type O blood if the RH factor is positive.
Correct Answer: A
Rationale: People with type AB blood are considered universal recipients because both A and B antigens are present on the red cell membrane. Clients with type AB blood can receive blood from persons with any type of blood, but the Rh factor must be compatible. The other distractors are incorrect because the client can receive blood from any type.
A client is brought to the emergency department with suspected bleeding esophageal varices. Which hemoglobin level should the nurse immediately report to the physician?
- A. 13.0 g/dL
- B. 10.2 g/dL
- C. 5.0 g/dL
- D. 11.4 g/dL
Correct Answer: C
Rationale: The nurse should immediately report a 5.0 g/dL, which is a critical low level. A 13.0 g/dL is a normal level, 11.4 is slightly low, and 10.2 is low.
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?
- 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
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.
