SECTION 1
1. Which of the following is the underlying pathology for hay fever?
A. Formation of autoantibodies.
B. Activation of complement.
C. Destruction by T-cells.
D. Mast cell degranulation.
Correct Answer:
Mast Cell Degranulation
Expert Rationale:
Hay fever (allergic rhinitis) is a Type I hypersensitivity reaction. Upon allergen exposure,
IgE bound to mast cells triggers cross-linking and degranulation, releasing histamine,
leukotrienes, and prostaglandins that produce the classic rhinorrhea, sneezing, and nasal
congestion.
2. Which of the following assessment findings would be expected in a patient who
presents with urticaria?
A. Eosinophilia.
B. Decreased thyroid-stimulation hormone level.
,C. Thrombocytopenia.
D. Leukopenia.
Correct Answer:
Eosinophilia
Expert Rationale:
Urticaria is a localized Type I hypersensitivity reaction involving mast cell degranulation
in the skin. The inflammatory cascade recruits eosinophils, making eosinophilia a
characteristic laboratory finding in allergic-mediated urticaria.
3. The diagnosis for an individual who presents to the office with sudden swollen lips
and eyes, shortness of breath and throat tightness after a bee sting is:
A. Anaphylaxis.
B. Asthma.
C. Angioedema.
D. Reactive airway disease.
Correct Answer:
Anaphylaxis
Expert Rationale:
The acute onset of angioedema (swollen lips/eyes), respiratory compromise (shortness
of breath, throat tightness), and known allergen exposure (bee sting) constitutes
anaphylaxis—a systemic, life-threatening IgE-mediated reaction requiring immediate
epinephrine administration.
4. Damage occurs with ABO incompatibility because:
A. Complement damages RBC membrane causing cell lysis.
B. Mast cell degranulation.
C. Autoantibodies specific for thyroid tissue impairs the receptors for TSH.
D. Antigen/Antibody complexes attack the RBC.
Correct Answer:
Complement damages RBC membrane causing cell lysis
,Expert Rationale:
ABO incompatibility triggers a Type II cytotoxic hypersensitivity reaction. Pre-formed
anti-A or anti-B antibodies bind to foreign RBC surface antigens, activating the classical
complement cascade and causing intravascular hemolysis via membrane attack complex
(MAC) formation.
5. Which is true about a primary immunodeficiency?
A. It is the result of a single gene defect.
B. It appears primarily in older adults.
C. It is usually inherited.
D. It is the result of multiple gene defects.
Correct Answer:
It is the result of a single gene defect.
Expert Rationale:
Primary immunodeficiencies are congenital disorders arising from genetic mutations—
most commonly single gene defects (e.g., SCID, CGD, Wiskott-Aldrich). They are present
from birth and are distinct from secondary (acquired) immunodeficiencies.
6. _____________ is a predominant cause of secondary immune deficiencies
worldwide.
Correct Answer:
Malnutrition
7. An example of a secondary immunodeficiency is:
A. Job Syndrome.
B. Common Variable Immunodeficiency.
C. Familial Mediterranean Fever.
D. Pneumocystis Carinii.
Correct Answer:
Pneumocystis Carinii.
, SECTION 2
Which of the following client(s) should the nurse practitioner (NP) recognize as being
at risk for developing folate deficiency? Select all that apply.
A 30-year-old client with severe anorexia nervosa
A 19-year-old client with sickle cell disease
A 27-year-old client who is newly pregnant and breastfeeding their toddler
A 40-year-old client with celiac disease
A 32-year-old client who had a gastrectomy one year ago
Correct Answer:
A 30-year-old client with severe anorexia nervosa
A 27-year-old client who is newly pregnant and breastfeeding their toddler
A 40-year-old client with celiac disease
Expert Rationale:
Folate deficiency arises from inadequate dietary intake, increased metabolic demands,
or malabsorption. Severe anorexia nervosa limits nutritional intake. Pregnancy and
lactation significantly increase folate requirements due to rapid cell division and fetal
development. Celiac disease causes villous atrophy in the small intestine, impairing
folate absorption. Sickle cell disease increases folate needs due to high erythropoietic
turnover but is more commonly associated with folate depletion rather than being a
primary risk factor in the same category. Post-gastrectomy clients are at risk for B12
deficiency due to loss of intrinsic factor, not folate deficiency.
A nurse practitioner (NP) evaluates a 45-year-old client who presents with fatigue and
weakness. The NP diagnoses the client with anemia of chronic disease. What is the
primary pathophysiological mechanism causing this normocytic anemia?
,Excessive blood loss
Defective erythropoiesis
Impaired iron absorption
Delayed maturation of erythrocyte precursors
Correct Answer: Defective erythropoiesis
Expert Rationale:
Anemia of chronic disease (ACD), also called anemia of inflammation, is primarily driven
by defective erythropoiesis. Inflammatory cytokines (IL-6) increase hepcidin production,
leading to iron sequestration within macrophages and reduced iron availability for
erythropoiesis. Additionally, chronic disease states blunt erythropoietin (EPO) response
and directly impair erythroid progenitor cell proliferation. While iron metabolism is
dysregulated, the fundamental mechanism is defective red blood cell production, not
merely impaired absorption or blood loss.
A nurse practitioner (NP) evaluates a 28-year-old client who presents with fatigue,
jaundice, and dark-colored urine. The NP diagnoses the client with hemolytic anemia.
What is the most likely pathophysiological mechanism causing this normocytic
anemia?
Impaired iron absorption
Excessive blood loss
Defective erythropoiesis
Increased red blood cell destruction
Correct Answer: Increased red blood cell destruction
Expert Rationale:
Hemolytic anemia is classified as a normocytic anemia characterized by premature
destruction of red blood cells (RBCs) exceeding the bone marrow's compensatory
capacity. The hallmark clinical manifestations—jaundice, dark urine (bilirubinuria), and
fatigue—result from elevated unconjugated bilirubin and hemoglobin breakdown
products. Unlike iron deficiency (impaired absorption) or aplastic anemia (defective
erythropoiesis), hemolytic anemia stems from intrinsic RBC defects (e.g., sickle cell,
thalassemia) or extrinsic immune-mediated destruction.
, SECTION 3
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
