Hematology Test Bank Questions with correct answersA 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.
