Chapter 32 : Assessment of Hematologic Function and Treatment Modalities Questions
Question 1 of 5
Which of the following circumstances would most clearly warrant autologous blood donation?
Correct Answer: C
Rationale: Autologous blood donation is useful for many elective surgeries where the potential need for transfusion is high. Type-O blood, hepatitis, sickle cell disease, and thalassemia are not clear indications for autologous donation.
Question 2 of 5
A patients electronic health record states that the patient receives regular transfusions of factor IX. The nurse would be justified in suspecting that this patient has what diagnosis?
Correct Answer: B
Rationale: Administration of clotting factors is used to treat diseases where these factors are absent or insufficient; hemophilia is among the most common of these diseases. Factor IX is not used in the treatment of leukemia, lymphoma, or anemia.
Question 3 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 4 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 5 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.
