Prep Questions, Test Bank Review,
and Concept Mastery
Question 1
Which client should the nurse practitioner (NP) recognize as most at risk for
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 leads to repeated loss of iron-containing red blood
cells, making this client highly susceptible to iron deficiency anemia. Pregnancy
increases iron demand, but regular phlebotomy is a more direct and consistent cause
of depletion. Peptic ulcers may cause bleeding, but not as predictably as scheduled
donations. Heart failure does not directly cause iron deficiency anemia.
Question 2
Which laboratory value best reflects total body iron stores?
A. Hemoglobin
B. Serum iron
C. Transferrin saturation
D. Serum ferritin
Correct Answer: D. Serum ferritin
Rationale: Serum ferritin is the most reliable indicator of iron storage in the body.
Hemoglobin reflects oxygen-carrying capacity, while serum iron and transferrin
saturation reflect circulating iron rather than stored iron levels.

Question 3
A client with beta-thalassemia major is most likely to require which ongoing
treatment?
A. Oral iron supplementation
B. Blood transfusions
C. Vitamin B12 injections
D. Anticoagulation therapy
Correct Answer: B. Blood transfusions
Rationale: Beta-thalassemia major causes severe ineffective erythropoiesis, requiring
regular blood transfusions to maintain adequate hemoglobin levels. Iron supplements
are contraindicated due to risk of iron overload.
Question 4
Which dietary instructions should the nurse include for a client with iron deficiency
anemia? (Select all that apply)
A. Avoid tea and coffee with meals
B. Consume lean red meat
C. Increase calcium intake with meals
D. Eat iron-fortified cereals
E. Take vitamin C with iron-rich foods
Correct Answer: A, B, D, E
Rationale: Tea and coffee reduce iron absorption, while vitamin C enhances
absorption. Red meat and fortified cereals are rich iron sources. Calcium inhibits iron
absorption and should not be emphasized with iron-rich meals.
Question 5
A couple are both carriers of thalassemia. What is the most appropriate nursing action?
(Select all that apply)
A. Advise them not to conceive
B. Refer for genetic counseling
C. Explain carrier status and inheritance patterns
D. Recommend contraceptive sterilization immediately
E. Discuss reproductive risk options
Correct Answer: B, C, E
,2026/2027
Rationale: Genetic counseling is essential to explain inheritance risks and
reproductive options. Nurses provide education and support rather than directive
reproductive decisions.
Question 6
Which findings should be prioritized to evaluate treatment effectiveness in a client
with thalassemia receiving transfusions? (Select all that apply)
A. Ferritin level
B. Hemoglobin level
C. Energy level
D. Blood pressure
E. Skin turgor
Correct Answer: A, B, C
Rationale: Hemoglobin reflects oxygen-carrying capacity, ferritin reflects iron
overload status, and energy level reflects functional improvement.
Question 7
Which client is most at risk for vitamin B12 deficiency anemia?
A. Infant exclusively breastfed
B. Client on high-protein diet
C. Pregnant client
D. Client post–vertical sleeve gastrectomy
Correct Answer: D. Client post–vertical sleeve gastrectomy
Rationale: Gastric surgery reduces intrinsic factor production and absorption sites,
significantly increasing B12 deficiency risk.
Question 8
Serum ferritin is best described as:
A. Oxygen-carrying protein
B. Iron transport molecule
C. Total body iron storage indicator
D. Red blood cell membrane protein
Correct Answer: C. Total body iron storage indicator
, 2026/2027
Rationale: Ferritin reflects stored iron levels in tissues and is the most sensitive
marker of iron deficiency.
Question 9
Microcytic anemia is commonly associated with:
A. Iron deficiency and thalassemia
B. Vitamin B12 deficiency
C. Acute blood loss only
D. Kidney failure
Correct Answer: A. Iron deficiency and thalassemia
Rationale: Microcytic anemia involves small RBCs due to impaired hemoglobin
synthesis, commonly seen in iron deficiency and thalassemia.
Question 10
Which condition is a Type 1 hypersensitivity reaction?
A. Hemolytic transfusion reaction
B. Graves disease
C. Asthma
D. Systemic lupus erythematosus
Correct Answer: C. Asthma
Rationale: Type 1 hypersensitivity is IgE-mediated and includes asthma, allergic
rhinitis, and anaphylaxis.
Question 11
Graves disease is classified as which hypersensitivity type?
A. Type I
B. Type II
C. Type III
D. Type IV
Correct Answer: B. Type II
Rationale: Graves disease is antibody-mediated (IgG) targeting TSH receptors,
leading to hyperthyroidism.
