Review 2026/2027
Question 1:
Which client should the nurse practitioner (NP) recognize as most at risk of
developing iron deficiency anemia?
A. A 25-year-old client who recently became pregnant
B. A 40-year-old client with a history of peptic ulcers
C. A 30-year-old client who donates blood every 3 months
D. A 50-year-old client with congestive heart failure
Correct Answer: C. A 30-year-old client who donates blood every 3 months
Rationale: Frequent blood donation reduces iron stores over time due to repeated loss
of red blood cells and iron content. While pregnancy increases iron demand, the
ongoing repetitive iron loss in frequent donors creates a sustained depletion risk.
Peptic ulcers may cause bleeding, but not necessarily as consistently as regular
donation. Heart failure does not directly cause iron deficiency.
Question 2:
Which laboratory value best reflects total body iron stores?
A. Serum iron
B. Hemoglobin
C. Serum ferritin
D. Transferrin saturation
Correct Answer: C. Serum ferritin
Rationale: Serum ferritin is the most reliable indicator of total iron stores in the body.
It reflects stored iron in tissues, particularly the liver and bone marrow. Serum iron
fluctuates daily and is not a stable marker. Hemoglobin reflects oxygen-carrying
capacity, not iron stores. Transferrin saturation reflects circulating iron but not total
storage.
Question 3:
,2026/2027
A client with beta thalassemia major is most likely to require which intervention?
A. Oral iron supplementation
B. Blood transfusions
C. Vitamin B12 therapy
D. Anticoagulation therapy
Correct Answer: B. Blood transfusions
Rationale: Beta thalassemia major causes severe ineffective erythropoiesis leading to
profound anemia, requiring lifelong regular blood transfusions. Iron supplementation
is contraindicated due to iron overload risk. Vitamin B12 deficiency is unrelated, and
anticoagulation is not a treatment for anemia.
Question 4:
Which dietary instructions should be included for a client with iron deficiency anemia?
Select all that apply.
A. Avoid tea or coffee with meals
B. Consume lean red meat
C. Increase calcium-rich foods
D. Eat iron-fortified cereals
E. Take vitamin C with iron-rich meals
Correct Answers: A, B, D, E
Rationale: Tea and coffee reduce iron absorption due to tannins. Red meat and
fortified cereals improve iron intake. Vitamin C enhances iron absorption. Calcium
competes with iron absorption and should not be increased with iron therapy.
Question 5:
Which actions are appropriate for a couple who are both carriers of thalassemia?
Select all that apply.
A. Discourage conception completely
B. Refer for genetic counseling
C. Explain carrier status
D. Discuss inheritance patterns
E. Prevent natural conception
Correct Answers: B, C, D
Rationale: Genetic counseling is essential to explain inheritance risks and carrier
status. Couples should be educated about autosomal recessive inheritance.
Discouraging or preventing conception is not appropriate nursing guidance.

Question 6:
Which laboratory values best evaluate treatment response in thalassemia major?
Select all that apply.
A. Hemoglobin level
B. Ferritin level
C. Energy level
D. Dietary intake
E. Developmental milestones
Correct Answers: A, B, C
Rationale: Hemoglobin reflects oxygen-carrying improvement. Ferritin monitors iron
overload from transfusions. Energy level reflects clinical improvement. Dietary intake
and developmental milestones are less direct indicators of treatment effectiveness.
Question 7:
Which client is at highest risk for vitamin B12 deficiency anemia?
A. Infant exclusively breastfed
B. Pregnant client
C. High-protein diet adult
D. Client post-vertical sleeve gastrectomy
Correct Answer: D. Client post-vertical sleeve gastrectomy
Rationale: Gastric surgery reduces intrinsic factor production, impairing B12
absorption. Breastfeeding infants are at moderate risk if maternal stores are low, but
surgical malabsorption is a stronger risk factor.
Question 8:
Which condition describes microcytic anemia?
A. Large red blood cells
B. Small red blood cells
C. Normal red blood cells
D. Increased hemoglobin concentration
Correct Answer: B. Small red blood cells
Rationale: Microcytic anemia is characterized by reduced RBC size, commonly due to
iron deficiency or thalassemia. Macrocytic anemia involves large cells, not small ones.

Question 9:
Which medication affects vitamin B12 absorption?
A. Metformin
B. Methotrexate
C. Anticonvulsants
D. All of the above
Correct Answer: D. All of the above
Rationale: Metformin, H2 blockers, and PPIs reduce B12 absorption. Anticonvulsants
and methotrexate impair folate metabolism but also indirectly affect hematologic
balance.
Question 10:
Which condition is the primary mechanism of anemia of chronic disease?
A. Excessive bleeding
B. Defective erythropoiesis
C. Iron deficiency
D. Increased RBC destruction
Correct Answer: B. Defective erythropoiesis
Rationale: Chronic inflammation suppresses erythropoietin response and impairs RBC
production. Iron stores may be normal or elevated, distinguishing it from iron
deficiency anemia.
Question 11:
Which mechanism causes hemolytic anemia?
A. Decreased RBC production
B. Increased RBC destruction
C. Impaired iron absorption
D. Bone marrow failure
Correct Answer: B. Increased RBC destruction
Rationale: Hemolytic anemia results from premature destruction of RBCs, leading to
elevated bilirubin and reticulocyte response.
