,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 (every 3 months) leads to chronic blood loss and depletion
of iron stores over time. While pregnancy increases iron demand and peptic ulcers can cause
chronic blood loss, the frequency of blood donation in this client creates the highest risk for iron
deficiency anemia. The body cannot replenish iron stores quickly enough with this donation
schedule.
2. The nurse practitioner (NP) reviews a client's laboratory results. Which laboratory result
best reflects the client's level of iron stores?
A. Transferrin saturation
B. Hemoglobin
C. Serum iron
D. Serum ferritin
E. Hematocrit
F. Total iron-binding capacity
Correct Answer: D – Serum ferritin
Rationale: Serum ferritin is the most sensitive and specific indicator of total body iron stores. It
reflects the amount of iron stored in the liver, spleen, and bone marrow. Low serum ferritin is
the first laboratory abnormality seen in iron deficiency anemia, often before changes in
hemoglobin or hematocrit occur. Transferrin saturation and total iron-binding capacity reflect
iron transport, while hemoglobin and hematocrit reflect the functional consequence of iron
deficiency rather than stores themselves.
3. The nurse practitioner (NP) is caring for a client with beta thalassemia major. The NP should
anticipate the client will require what?
,Correct Answer: A blood transfusion
Rationale: Beta thalassemia major (Cooley's anemia) is a severe inherited hemoglobinopathy
characterized by defective beta-globin chain synthesis, leading to ineffective erythropoiesis and
severe hemolytic anemia. These clients typically require lifelong regular blood transfusions to
maintain adequate hemoglobin levels and suppress ineffective erythropoiesis. Transfusions are
essential for growth, development, and survival, though they lead to iron overload requiring
chelation therapy.
4. The nurse practitioner (NP) is counseling a client with iron deficiency anemia about dietary
needs. Which instruction(s) should the NP include? (Select all that apply)
A. Avoid drinking tea or coffee with meals
B. Consume lean red meat
C. Increase intake of calcium-rich foods
D. Consume iron-fortified cereal
E. Consume vitamin C-rich foods with iron-rich meals
Correct Answers: A, B, D, E
Rationale:
• Tea and coffee contain tannins and polyphenols that inhibit non-heme iron absorption
and should be avoided with meals.
• Lean red meat is an excellent source of highly bioavailable heme iron.
• Iron-fortified cereals provide non-heme iron supplementation.
• Vitamin C enhances non-heme iron absorption by reducing ferric iron to the more
absorbable ferrous form and forming a chelate with iron.
• Calcium-rich foods should NOT be increased with iron-rich meals, as calcium competes
with iron for absorption in the duodenum.
5. A nurse practitioner (NP) is providing pre-conception counseling to a couple, both of whom
are carriers of thalassemia. Which of the following actions should the NP take? (Select all that
apply)
A. Encourage the couple not to conceive
B. Refer the couple for genetic counseling
, C. Explain what it means to be a carrier of thalassemia
D. Discuss ways to prevent naturally conceiving a child with thalassemia
E. Discuss inheritance patterns of thalassemia
Correct Answers: B, C, D, E
Rationale: When both parents are carriers of thalassemia trait, there is a 25% chance with each
pregnancy of having a child with thalassemia major, a 50% chance of having a carrier child, and
a 25% chance of having an unaffected child. The NP should provide education about inheritance
patterns, explain carrier status, discuss reproductive options (preimplantation genetic diagnosis,
prenatal testing), and refer for genetic counseling. The couple should NOT be discouraged from
conceiving entirely, but rather empowered with information to make informed reproductive
decisions.
6. The nurse practitioner (NP) assesses the client on a follow-up visit after the initiation of
treatment for thalassemia including administration of blood transfusions. What three (3)
assessments should the NP prioritize to evaluate client outcomes? (Select all that apply)
A. Dietary intake
B. Developmental milestones
C. Ferritin level
D. Hemoglobin level
E. Energy level
Correct Answers: C, D, E
Rationale: The primary goals of transfusion therapy in thalassemia are to maintain adequate
hemoglobin levels (typically 9-10 g/dL) to suppress ineffective erythropoiesis and improve tissue
oxygenation. Monitoring hemoglobin ensures transfusion adequacy. Ferritin tracks iron
overload from repeated transfusions, which is critical for timing chelation therapy. Energy level
is a subjective measure of improved oxygen-carrying capacity and quality of life. While dietary
intake and developmental milestones are important in pediatric thalassemia, they are not the
priority assessments for evaluating transfusion therapy outcomes specifically.
7. Which of the following clients should the nurse practitioner (NP) recognize as being most at
risk for developing vitamin B-12 deficiency anemia?
A. An infant who is exclusively breastfed
B. Middle adult client who eats a high-protein diet
