The nurse is reviewing laboratory studies that determine a client is deficient in copper. What does the nurse understand is the importance of copper in the body?
- A. Essential for the maturation of red blood cells
- B. Basic nutritional component of heme in hemoglobin
- C. Involved in the transfer of iron from storage to plasma
- D. Serves as a coenzyme in hemoglobin formation
Correct Answer: C
Rationale: Copper is involved in the transfer of iron from storage to plasma. Folic acid and Bâ??â?? are essential for the maturation of red blood cells. Iron is the basic nutritional component of heme in hemoglobin. Vitamin B6 serves as a coenzyme in hemoglobin formation.

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.
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 is taking a medication that has the side effect of depressing the hematopoietic system. What signs of leukopenia should the nurse monitor for while the client is taking this drug?
- A. Fever, sore throat, and chills
- B. Nausea and vomiting
- C. Diarrhea, diaphoresis, and fever
- D. Intolerance to heat and rash
Correct Answer: A
Rationale: Closely monitor clients taking medications that depress the hematopoietic system, particularly thrombocytes and leukocytes. Signs of leukopenia include fever, sore throat, and chills. Nausea and vomiting, diarrhea, diaphoresis, heat intolerance, and rash are not indicative of leukocytosis.
The nurse is caring for three clients who have the following blood count values: Client A has 24,500/mm?³ white blood cells (WBCs), client B has 13.4 g/dL hemoglobin, and client C has a 250,000/mm?³ 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 lower WBC count than normal, client B has a normal hemoglobin count, and client C has a normal platelet count.
Correct Answer: B
Rationale: The normal leukocyte count is between 5000 and 10,000/mm?³. Client A has an increased number of leukocytes greater than 10,000/mm?³ 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/mm?³ platelets; therefore, client C has a normal platelet count.
The nurse is inspecting the tonsils for a client with a fever and sore throat. The nurse observes purulent exudate on the surface of the tonsils. What does this finding indicate to the nurse?
- A. Filariasis
- B. Thrush
- C. An abscess
- D. Tonsillitis
Correct Answer: D
Rationale: Purulent exudate on the surface of the tonsils suggests tonsillitis. Filariasis is also known as elephantiasis and is a consequence of a roundworm infection in which the lymphatic vessels become occluded. An abscess would not have purulent drainage on the surface unless ruptured.
