• Infection and Stress Responses
• Integrative Pathophysiologic Reasoning
Introduction
,This original NURS 6501-style midterm practice bank assesses
advanced pathophysiologic reasoning across body systems. It
emphasizes cellular mechanisms, genetic influences, regulatory
pathways, and clinical decision-making. Questions are scenario-
based and require application of foundational science to real-world
patient presentations. The practice set supports exam preparation
by reinforcing cause-effect relationships, compensatory
mechanisms, and evidence-based rationale.
SECTION ONE: QUESTIONS 1–20
Question 1
A 58-year-old smoker has bronchial biopsy showing columnar
epithelium replaced by stratified squamous cells. Which adaptation
is this?
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Anaplasia
RATIONALE: Metaplasia is reversible replacement of one
mature cell type by another due to chronic irritation, such as
smoking.
Question 2
A 72-year-old with vomiting has serum Na 119 mEq/L and
confusion. Which mechanism causes symptoms?
A. Cellular dehydration
B. Cerebral edema
,C. Hyperkalemia
D. Metabolic alkalosis
RATIONALE: Hyponatremia lowers extracellular osmolality,
causing water to shift into brain cells and produce cerebral edema.
Question 3
A myocardial infarct shows preserved cell outlines with protein
denaturation. Which necrosis is this?
A. Liquefactive
B. Caseous
C. Coagulative
D. Fat
RATIONALE: Coagulative necrosis preserves tissue architecture
and occurs in ischemic injury to solid organs such as the heart.
Question 4
A child has recurrent bacterial infections, absent tonsils, and absent
B cells. Which disorder is most likely?
A. Severe combined immunodeficiency
B. X-linked agammaglobulinemia
C. Common variable immunodeficiency
D. DiGeorge syndrome
RATIONALE: X-linked agammaglobulinemia causes failure of
B-cell maturation and absent immunoglobulins.
Question 5
, A 28-year-old with diarrhea has pH 7.28, HCO3 18, PaCO2 32.
Which acid-base disorder is present?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis with respiratory compensation
D. Metabolic alkalosis
RATIONALE: Low pH and low bicarbonate indicate metabolic
acidosis; low PaCO2 shows respiratory compensation.
Question 6
A 62-year-old with right heart failure has jugular venous distension
and edema. Which mechanism causes edema?
A. Decreased oncotic pressure
B. Increased hydrostatic pressure
C. Lymphatic obstruction
D. Increased capillary permeability
RATIONALE: Right heart failure raises venous hydrostatic
pressure, forcing fluid into interstitial spaces.
Question 7
A 55-year-old has microcytic anemia, low ferritin, and glossitis.
Which cause is most likely?
A. Vitamin B12 deficiency
B. Iron deficiency from chronic blood loss
C. Folate deficiency
D. Anemia of chronic disease
