and Study Notes
Question 1:
A nursing student is reviewing the role of folic acid in erythropoiesis. Which
statement best explains the primary function of folic acid in the maturation of red
blood cells (RBCs)?
A. It stimulates erythropoietin release from the kidneys
B. It assists in hemoglobin synthesis within mature erythrocytes
C. It participates in DNA and RNA synthesis necessary for RBC maturation
D. It promotes platelet aggregation during hematopoiesis
Correct Answer: C. It participates in DNA and RNA synthesis necessary for
RBC maturation
Rationale: Folic acid is the synthetic form of folate and is converted in the body to
tetrahydrofolic acid (THF), a coenzyme essential for the synthesis of purines and
pyrimidines used in DNA and RNA production. Proper DNA synthesis is critical for
normal nuclear maturation and division of red blood cell precursors in the bone
marrow. A deficiency impairs cell division, resulting in megaloblastic anemia. Option
A is incorrect because erythropoietin secretion is primarily regulated by renal oxygen
sensing. Option B is incorrect because iron, not folic acid, plays the central role in
hemoglobin synthesis. Option D is unrelated to folic acid’s primary hematologic
function.
Question 2:
A healthcare provider explains the DNA synthesis pathway to a patient diagnosed
with megaloblastic anemia. Which description best defines the DNA synthesis
pathway?
A. Breakdown of RNA into amino acids for protein synthesis
B. Separation of the DNA double helix followed by synthesis of complementary
strands
C. Conversion of hemoglobin into myoglobin during erythropoiesis
D. Degradation of nucleic acids to maintain cellular homeostasis
,2026/2027
Correct Answer: B. Separation of the DNA double helix followed by synthesis of
complementary strands
Rationale: DNA synthesis involves unwinding and separating the DNA double helix,
after which complementary DNA strands are synthesized using the original strands as
templates. This process is essential for cell division and normal maturation of rapidly
dividing cells, including erythrocyte precursors. Option A describes protein
metabolism rather than DNA replication. Option C is unrelated to nucleic acid
synthesis, and Option D describes catabolism rather than replication.
Question 3:
Normal red blood cell nuclear maturation requires which combination of coenzymes
for effective DNA synthesis?
A. Iron and vitamin K
B. Vitamin C and iron
C. Folate and vitamin B12
D. Calcium and magnesium
Correct Answer: C. Folate and vitamin B12
Rationale: Folate and vitamin B12 are both essential coenzymes required for DNA
synthesis and normal nuclear maturation of erythrocyte precursors. Deficiency of
either nutrient disrupts DNA replication, causing impaired maturation and
megaloblastic anemia. Iron is necessary for hemoglobin production, not DNA
synthesis. Vitamin K functions in clotting factor synthesis, while calcium and
magnesium are involved in neuromuscular and metabolic processes rather than
erythropoiesis.
Question 4:
A patient is diagnosed with von Willebrand disease. The nurse understands that von
Willebrand factor (VWF) primarily functions to:
A. Stimulate fibrinolysis during clot breakdown
B. Promote platelet adhesion and stabilize factor VIII
C. Convert fibrinogen to fibrin
D. Activate antithrombin III
Correct Answer: B. Promote platelet adhesion and stabilize factor VIII
Rationale: Von Willebrand factor is a large adhesive glycoprotein that is essential for
platelet adhesion to damaged vascular endothelium and platelet aggregation during
primary hemostasis. It also stabilizes clotting factor VIII in circulation. Deficiency or
dysfunction results in prolonged bleeding. Option A describes fibrinolysis, which is
,2026/2027
mediated primarily by plasmin. Option C is the role of thrombin, and Option D relates
to anticoagulation mechanisms.
Question 5:
A nurse is teaching a class about hemostasis. Which process is von Willebrand factor
directly involved in?
A. Fibrin degradation
B. Platelet adhesion and aggregation
C. Red blood cell destruction
D. Activation of plasminogen
Correct Answer: B. Platelet adhesion and aggregation
Rationale: Von Willebrand factor directly participates in platelet adhesion to injured
endothelium and platelet aggregation to form the initial platelet plug. This mechanism
is essential in preventing excessive bleeding after vascular injury. Fibrin degradation
involves plasmin, not VWF. Red blood cell destruction occurs in hemolysis, and
plasminogen activation is associated with fibrinolysis.
Question 6:
A 50-year-old patient experiencing an acute ischemic stroke is prescribed
recombinant tissue plasminogen activator (t-PA). What is the primary therapeutic
effect of this medication?
A. Prevention of platelet aggregation
B. Promotion of fibrinolysis
C. Activation of factor VIII
D. Enhancement of clot formation
Correct Answer: B. Promotion of fibrinolysis
Rationale: Recombinant tissue plasminogen activator (t-PA), such as alteplase,
converts plasminogen to plasmin, which dissolves fibrin clots. This promotes
fibrinolysis and restores blood flow in acute ischemic stroke or myocardial infarction.
Option A describes antiplatelet agents like aspirin. Options C and D would worsen
thrombosis rather than resolve it.
Question 7:
A patient with acute myocardial infarction receives alteplase therapy. The nurse
understands that the medication works by activating plasminogen in order to:
, 2026/2027
A. Increase platelet production
B. Promote fibrinolysis and dissolve thrombi
C. Stimulate erythropoiesis
D. Prevent ventricular remodeling
Correct Answer: B. Promote fibrinolysis and dissolve thrombi
Rationale: Alteplase activates plasminogen, forming plasmin that breaks down fibrin
within blood clots. This action restores perfusion to ischemic tissues during
myocardial infarction or stroke. Platelet production occurs in the bone marrow and is
unaffected by alteplase. Erythropoiesis and ventricular remodeling are unrelated to
fibrinolytic therapy.
Question 8:
Which characteristic most strongly distinguishes non-Hodgkin lymphoma from
Hodgkin lymphoma?
A. Presence of Reed-Sternberg cells
B. Localized involvement of a single lymph node group
C. Multiple peripheral lymph nodes commonly involved
D. Occurrence only in pediatric patients
Correct Answer: C. Multiple peripheral lymph nodes commonly involved
Rationale: Non-Hodgkin lymphoma commonly involves multiple peripheral lymph
nodes and extranodal tissues at diagnosis. Hodgkin lymphoma typically spreads in an
orderly fashion and is associated with Reed-Sternberg cells. Option A describes
Hodgkin lymphoma. Option B is more characteristic of early Hodgkin disease. Option
D is incorrect because non-Hodgkin lymphoma can occur at any age.
Question 9:
In Hodgkin lymphoma, defective B lymphocytes commonly arise due to:
A. Excessive iron accumulation
B. Errors in immunoglobulin gene arrangement
C. Viral destruction of T lymphocytes
D. Decreased erythropoietin secretion
Correct Answer: B. Errors in immunoglobulin gene arrangement
Rationale: Hodgkin lymphoma originates from abnormal B lymphocytes that develop
due to errors in immunoglobulin gene rearrangement. These defective cells can evolve
into malignant Reed-Sternberg cells. Iron accumulation and erythropoietin secretion
are unrelated. Viral T-cell destruction is associated more with HIV infection.
