Chapter 32 Questions
Question 1 of 5
A patient with a hematologic disorder asks the nurse how the body forms blood cells. The nurse should describe a process that takes place where?
Correct Answer: C
Rationale: Bone marrow is the primary site for hematopoiesis. The liver and spleen may be involved during embryonic development or when marrow is destroyed. The kidneys release erythropoietin, which stimulates the marrow to increase production of red blood cells (RBCs). However, blood cells are not primarily formed in the spleen, kidneys, or liver.
Question 2 of 5
A man suffers a leg wound which causes minor blood loss. As a result of bleeding, the process of primary hemostasis is activated. What occurs in primary hemostasis?
Correct Answer: A
Rationale: Primary hemostasis involves the severed vessel constricting and platelets collecting at the injury site. Secondary hemostasis occurs when thromboplastin is released, prothrombin converts to thrombin, and fibrin is lysed.
Question 3 of 5
A patient has come to the OB/GYN clinic due to recent heavy menstrual flow. Because of the patients consequent increase in RBC production, the nurse knows that the patient may need to increase her daily intake of what substance?
Correct Answer: C
Rationale:
To replace blood loss, the rate of red cell production increases. Iron is incorporated into hemoglobin. Vitamins E and D and magnesium do not need to be increased when RBC production is increased.
Question 4 of 5
The nurse is planning the care of a patient with a nutritional deficit and a diagnosis of megaloblastic anemia. The nurse should recognize that this patients health problem is due to what?
Correct Answer: D
Rationale: Vitamin B12 and folic acid deficiencies are characterized by the production of abnormally large erythrocytes called megaloblasts. Because these cells are abnormal, many are sequestered (trapped) while still in the bone marrow, and their rate of release is decreased. Some of these cells actually die in the marrow before they can be released into the circulation. This results in megaloblastic anemia. This pathologic process does not involve inadequate production, premature release, or injury to existing RBCs.
Question 5 of 5
A nurse is caring for a patient who undergoing preliminary testing for a hematologic disorder. What sign or symptom most likely suggests a potential hematologic disorder?
Correct Answer: D
Rationale: The most common indicator of hematologic disease is extreme fatigue. This is more common than changes in LOC, infections, or anaphylaxis.
