Questions and CORRECT Answers
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?
A) In the spleen
B) In the kidneys
C) In the bone marrow
D) In the liver - CORRECT ANSWER- ✔✔Ans: C
Feedback:
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.
A patient has come to the OB/GYN clinic due to recent heavy menstrual flow. Because of the
patient's consequent increase in RBC production, the nurse knows that the patient may need
to increase her daily intake of what substance?
A) Vitamin E
B) Vitamin D
C) Iron
D) Magnesium - CORRECT ANSWER- ✔✔Ans: C
,Feedback:
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.
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?
A) Sudden change in level of consciousness (LOC)
B) Recurrent infections
C) Anaphylaxis
D) Severe fatigue - CORRECT ANSWER- ✔✔Ans: D
Feedback:
The most common indicator of hematologic disease is extreme fatigue. This is more common
than changes in LOC, infections, or analphylaxis.
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?
A) Notify the patient's physician.
B) Stop the transfusion immediately.
C) Remove the patient's IV access.
,D) Assess the patient's chest sounds and vital signs. - CORRECT ANSWER- ✔✔Ans: B
Feedback:
Vascular collapse, bronchospasm, laryngeal edema, shock, fever, chills, and jugular vein
distension are severe reactions. The nurse should discontinue the transfusion immediately,
monitor the patient's 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 patient's IV access should not be removed.
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?
A) Spleen and kidneys
B) Kidneys and pancreas
C) Pancreas and liver
D) Liver and spleen - CORRECT ANSWER- ✔✔Ans: D
Feedback:
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.
A patient undergoing a hip replacement has autologous blood on standby if a transfusion is
needed. What is the primary advantage of autologous transfusions?
A) Safe transfusion for patients with a history of transfusion reactions
, B) Prevention of viral infections from another person's blood
C) Avoidance of complications in patients with alloantibodies
D) Prevention of alloimmunization - CORRECT ANSWER- ✔✔Ans: B
Feedback:
The primary advantage of autologous transfusions is the prevention of viral infections from
another person's blood. Other secondary advantages include safe transfusion for patients with
a history of transfusion reactions, prevention of alloimmunization, and avoidance of
complications in patients with alloantibodies.
The nurse is describing normal RBC physiology to a patient who has a diagnosis of anemia.
The nurse should explain that the RBCs consist primarily of which of the following?
A) Plasminogen
B) Hemoglobin
C) Hematocrit
D) Fibrin - CORRECT ANSWER- ✔✔Ans: B
Feedback:
Mature erythrocytes consist primarily of hemoglobin, which contains iron and makes up 95%
of the cell mass. RBCs are not made of fibrin or plasminogen. Hematocrit is a measure of
RBC volume in whole blood.
A patient is being treated for the effects of a longstanding vitamin B12 deficiency. What
aspect of the patient's health history would most likely predispose her to this deficiency?
