Questions with Correct Answers & Rationales | Chamberlain 2026/2027
Pass your family or psychiatric nurse practitioner barrier assessment with this definitive
2026/2027 NR 507 Week 8 Advanced Pathophysiology final exam practice bank. This
comprehensive preparation guide features high-yield clinical questions paired with
100% verified correct answers and detailed biological rationales covering cellular
alterations, multi-system organ dynamics, cardiovascular pathophysiology, and renal
regulatory mechanisms. It is the ultimate tool for graduate nursing students looking to
compress study time, master complex case scenarios, and confidently lock in an A+
grade.
QUESTIONS 1-200
1. A 72-year-old patient with chronic heart failure presents with progressive
dyspnea, fatigue, and peripheral edema. Echocardiogram reveals left ventricular
hypertrophy. This cardiac remodeling is best described as:
A. Physiological hypertrophy
B. Compensatory hyperplasia
C. Dysplasia
D. Pathological hypertrophy
Rationale: Pathological hypertrophy is an increase in cell size in response to increased
workload or injury. In heart failure, the left ventricle hypertrophies to compensate for
increased afterload, but this adaptation is maladaptive and leads to further dysfunction .
2. A patient with a chronic venous stasis ulcer has non-healing wound tissue that
shows evidence of necrosis with preservation of tissue architecture. This type of
necrosis is best described as:
,A. Liquefactive necrosis
B. Caseous necrosis
C. Fat necrosis
D. Coagulative necrosis
Rationale: Coagulative necrosis is the most common type of necrosis in solid organs and
occurs when ischemia causes cell death while the structural framework remains preserved.
This is characteristic of infarction.
3. In cellular metabolism, each enzyme has a high affinity for which of the
following?
A. Product
B. Cofactor
C. Inhibitor
D. Substrate
Rationale: Enzymes are highly specific and have high affinity for their specific substrates.
This affinity allows enzymes to catalyze reactions efficiently at low substrate
concentrations .
4. Which characteristic best differentiates benign tumors from malignant tumors?
A. Rapid growth rate
B. Invasive growth pattern
C. Well-differentiated cells that resemble tissue of origin
D. Presence of metastasis
Rationale: Benign tumors are well-differentiated, resemble their tissue of origin, grow
slowly, and do not metastasize. Malignant tumors are poorly differentiated (anaplastic),
invade surrounding tissues, and metastasize .
,5. Down syndrome is characterized by which chromosomal abnormality?
A. Monosomy of chromosome 21
B. Trisomy 21
C. Deletion of chromosome 5
D. Translocation of chromosome 18
Rationale: Down syndrome (Trisomy 21) results from an extra copy of chromosome 21.
Risk factors include advanced maternal age. Characteristics include flat facies, simian
crease, gap between first two toes, and intellectual disability .
6. Klinefelter syndrome is characterized by which karyotype?
A. XYY
B. XXX
C. XO
D. XXY
Rationale: Klinefelter syndrome occurs when an XY person has an extra X chromosome,
causing less testosterone production. Manifestations include hypogonadism, sterility, tall
stature, gynecomastia, and increased risk of breast cancer and osteoporosis .
7. A 4-month-old infant presents with chronic diarrhea, thrush, and recurrent
pneumonia. Chest X-ray shows an absent thymic shadow. Which diagnosis is most
likely?
A. Selective IgA deficiency
B. Chronic granulomatous disease
C. Common variable immunodeficiency
D. Severe combined immunodeficiency (SCID)
Rationale: SCID causes combined T- and B-cell dysfunction, leading to severe, recurrent
infections early in infancy. Absent thymic shadow on X-ray is a characteristic finding .
, 8. A patient with suspected systemic lupus erythematosus (SLE) undergoes
laboratory testing. Which finding is most specific for SLE?
A. Elevated erythrocyte sedimentation rate (ESR)
B. Decreased complement levels (C3, C4)
C. Elevated C-reactive protein (CRP)
D. Positive antinuclear antibody (ANA)
Rationale: A positive ANA is a hallmark finding in SLE. Low complement levels indicate
immune complex consumption and correlate with active SLE disease activity. SLE is a
systemic autoimmune disease; the malar "butterfly" rash is a classic diagnostic sign .
9. A patient presents with a butterfly-shaped rash on the face and joint pain. This
presentation is highly suggestive of:
A. Rheumatoid arthritis
B. Osteoarthritis
C. Gout
D. Systemic lupus erythematosus (SLE)
Rationale: SLE is a systemic autoimmune disease; the malar "butterfly" rash is a classic
diagnostic sign .
10. What is the underlying cause of myasthenia gravis?
A. Destruction of the myelin sheath
B. Autoimmune blockade or destruction of acetylcholine receptors
C. Deficiency of dopamine in the basal ganglia
D. Inflammation of the meninges
Rationale: Myasthenia gravis is an autoimmune disorder affecting the neuromuscular
junction, where antibodies block or destroy acetylcholine receptors, preventing nerve
impulses from triggering muscle contractions .
