,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:
A 30-year-old client who donates blood every 3 months
Expert Rationale:
Frequent whole-blood donation depletes iron stores because each donation removes
approximately 200–250 mg of iron. Donating every 3 months (the minimum interval
allowed by most blood banks) chronically strains erythropoiesis and iron reserves,
making this the highest-risk scenario among the options. While pregnancy increases
iron demand and peptic ulcers cause chronic occult blood loss, the volume and
frequency of blood loss in regular donation typically exceed those losses. CHF is not a
primary risk factor for iron deficiency anemia.
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:
Serum ferritin
Expert Rationale:
Serum ferritin is the most sensitive and specific laboratory indicator of total body iron
stores. It reflects the amount of iron stored in the reticuloendothelial system and
hepatocytes. Hemoglobin and hematocrit are late indicators of iron deficiency and do
not reflect stores. Serum iron fluctuates with recent intake and diurnal variation. Total
iron-binding capacity (TIBC) rises when transferrin is upregulated in deficiency, but it
measures transport capacity, not storage. Transferrin saturation indicates iron
availability for erythropoiesis but is also affected by inflammation.
,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
Expert Rationale:
Beta thalassemia major (Cooley anemia) involves defective beta-globin chain
synthesis, leading to severe microcytic, hypochronic anemia and ineffective
erythropoiesis. These patients are transfusion-dependent lifelong to maintain adequate
hemoglobin levels and suppress extramedullary hematopoiesis. Transfusions, however,
lead to iron overload, necessitating concurrent iron 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 Answer:
Avoid drinking tea or coffee with meals; Consume lean red meat; Consume iron-fortified
cereal; Consume vitamin C-rich foods with iron-rich meals
Expert Rationale:
Tea and coffee contain polyphenols and tannins that inhibit non-heme iron absorption
and should be avoided with meals. Lean red meat provides highly bioavailable heme
iron. Iron-fortified cereals are an important source of non-heme iron. Vitamin C (ascorbic
acid) reduces ferric iron to the more absorbable ferrous form and forms a chelate that
enhances absorption. Calcium-rich foods should not be increased with iron meals
because 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 Answer:
Refer the couple for genetic counseling; Explain what it means to be a carrier of
thalassemia; Discuss inheritance patterns of thalassemia
Expert Rationale:
Both parents being carriers of beta-thalassemia trait confer a 25% risk with each
pregnancy of having a child with thalassemia major. The NP must educate on
autosomal recessive inheritance patterns and ensure referral to genetic counseling for
prenatal testing options (CVS, amniocentesis, preimplantation genetic diagnosis). The
NP should not discourage conception outright; rather, the couple should be 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 3.
A. Dietary intake
B. Developmental milestones
C. Ferritin level
D. Hemoglobin level
E. Energy level
Correct Answer:
Ferritin level; Hemoglobin level; Energy level
Expert Rationale:
Hemoglobin level confirms the adequacy of transfusion therapy in maintaining oxygen-
carrying capacity. Ferritin is critical because repeated transfusions cause iron overload;
chelation therapy is initiated when ferritin exceeds 1,000 ng/mL. Energy level is a
patient-reported outcome reflecting tissue oxygenation and anemia correction. While
dietary intake and developmental milestones are relevant in pediatric thalassemia, they
are not the three priority assessments for evaluating transfusion outcomes in the
general NP follow-up context.
