Why would it be important for the nurse to obtain information regarding the dietary history of a client with a possible abnormality of the hematopoietic or lymphatic system?
- A. It could determine if the illness is self-induced by nutritional starvation.
- B. If the client has impaired protein intake, it will cause diseases of the hematopoietic system.
- C. Altered nutrition is the cause of abnormalities of the hematopoietic and lymphatic system.
- D. Compromised nutrition interferes with production of blood cells and hemoglobin.
Correct Answer: D
Rationale: The nurse obtains a dietary history because compromised nutrition interferes with the production of blood cells and hemoglobin. The history cannot determine if the illness is self-induced by starvation. Nutritional deficiencies do not cause diseases of the hematopoietic system and lymphatic system.

A nurse is providing care to a cancer client. Which protein in plasma functions primarily as immunologic agents?
- A. Gamma globulins
- B. Albumin
- C. Fibrinogen
- D. Beta globulins
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.
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 has been involved in an automobile accident and is assessed to have an enlarged spleen. What does the nurse understand is the significance of attempting to prevent unnecessary removal of the spleen for this client?
- A. The spleen is a large lymph node and takes waste debris away.
- B. The spleen is a lymphatic structure and assists with phagocytosis
- C. The spleen is lymphoid tissue in the upper chest that contains stem cells.
- D. The spleen assists with blood clotting.
Correct Answer: B
Rationale: The spleen is the largest lymphatic structure, is a reservoir of blood, and contains phagocytes that engulf damaged erythrocytes and foreign substances. Lymph fluid takes waste debris away. The thymus is lymphoid tissue that is in the upper chest and contains stem cells. The spleen does not assist with blood clotting.
A client informs the nurse that he is having a difficult time coping with seasonal allergies and has taken some over-the-counter medications to assist with control of symptoms. What results would indicate to the nurse that the client does have allergies?
- A. Elevated eosinophils
- B. Elevated basophils
- C. Elevated monocytes
- D. Elevated neutrophils
Correct Answer: A
Rationale: Eosinophils phagocytize foreign material. Their numbers increase in allergies, some dermatologic disorders, and parasitic infections. Basophils are also capable of phagocytosis; they are active in allergic contact dermatitis and some delayed hypersensitivity reactions. Monocytes engulf microbial invaders and display the antigenic surface to T lymphocytes. Neutrophils are a major component of the inflammatory response and defense against bacterial infection.
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.
