Chapter 32 : Assessment of Hematologic Function and Treatment Modalities Questions
Question 1 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.
Question 2 of 5
The nurse caring for a patient receiving a transfusion notes that 15 minutes after the infusion of packed red blood cells (PRBCs) has begun, the patient is having difficulty breathing and complains of severe chest tightness. What is the most appropriate initial action for the nurse to take?
Correct Answer: B
Rationale: Vascular collapse, bronchospasm, laryngeal edema, shock, fever, chills, and jugular vein distension are severe reactions. The nurse should discontinue the transfusion immediately, monitor the patients vital signs, and notify the physician. The blood container and tubing should be sent to the blood bank. A blood and urine specimen may be needed if a transfusion reaction or a bacterial infection is suspected. The patients IV access should not be removed.
Question 3 of 5
The nurse is describing the role of plasminogen in the clotting cascade. Where in the body is plasminogen present?
Correct Answer: B
Rationale: Plasminogen, which is present in all body fluids, circulates with fibrinogen. Plasminogen is found in body fluids, not tissue.
Question 4 of 5
The nurse is caring for a patient who has developed scar tissue in many of the areas that normally produce blood cells. What organs can become active in blood cell production by the process of extramedullary hematopoiesis?
Correct Answer: D
Rationale: In adults with disease that causes marrow destruction, fibrosis, or scarring, the liver and spleen can also resume production of blood cells by a process known as extramedullary hematopoiesis. The kidneys and pancreas do not produce blood cells for the body.
Question 5 of 5
Through the process of hematopoiesis, stem cells differentiate into either myeloid or lymphoid stem cells. Into what do myeloid stem cells further differentiate?
Correct Answer: A,D,E
Rationale: Myeloid stem cells differentiate into three broad cell types: erythrocytes, leukocytes, and platelets. Natural killer cells and cytokines do not originate as myeloid stem cells.
