MULTIPLE CHOICE

1. A client, receiving a transfusion of packed red blood cells, asks the nurse why it is needed since she knows the body makes new blood. Which of the following should the nurse respond to this client?

ANS:  4

Red blood cells have a life span of about 120 days. Abnormal red blood cells have a shorter life span and are lysed and extracted from the circulation. The nurse should explain that since red blood cells live 120 days, the body needs a constant supply. The transfusion will provide the cells until the body makes new ones.

2. The nurse is reviewing a client’s white blood cell count. Which of the following would not be affected by the presence of an infection?

ANS:  3

Basophils, eosinophils, and neutrophils are considered granulocytes which are present in increased amounts in the presence of an infection. Lymphocytes are common in the lymphatic system and work with acquired immunity.

3. A client is diagnosed with a parasitic infection. The nurse realizes that which of the following white blood cell counts will be elevated?

ANS:  2

Eosinophils are classically associated with infections from parasites. Eosinophils are also more involved in the reactions to allergies. Basophils are central to the inflammatory process and neutrophils respond to bacterial infections. Lymphocytes are cells that work in acquired immunity.

4. A client is diagnosed with a low red blood cell count. Which of the following should the nurse assess in this client?

ANS:  3

The function of the erythrocyte or red blood cell is to transport oxygen from the lungs to the cells of the body. With a low red blood cell count, the nurse should assess the client’s respiratory status. The urine output, bowel sounds, and consciousness may or may not be affected by the decrease in red blood cells.

PTS:   1                    DIF:    Apply            REF:   Erythrocytes

5. A client is prescribed a vitamin B-12 injection every month. Which of the following should the nurse explain to the client as the purpose of this medication?

ANS:  1

Vitamin B-12 is necessary to make erythrocytes and help make thymine, which is a precursor to the red blood cell. The erythrocyte cytoskeleton makes the red blood cell more flexible. Cholesterol helps the red blood cells hold their shape. There is nothing physiologically that will make a red blood cell hold more oxygen.
