1.
A 58-year-old patient with a history of poorly controlled hypertension presents
with progressive fatigue, decreased exercise tolerance, and peripheral edema.
Laboratory studies demonstrate an elevated serum creatinine and reduced
estimated glomerular filtration rate. The provider explains that persistent
hypertension has produced structural and functional changes in the kidneys over
several years. Which pathophysiologic mechanism best explains how chronic
hypertension can contribute to progressive renal dysfunction?
A. Persistent elevation of systemic pressure damages renal vascular structures and
promotes nephron injury
B. Hypertension directly increases erythropoietin production and causes nephron
regeneration
C. Elevated arterial pressure prevents glomerular filtration by completely closing
all renal capillaries
D. Chronic hypertension causes the kidneys to eliminate excessive sodium without
vascular injury
Answer: A
2.
A 42-year-old patient presents with several weeks of fatigue, recurrent infections,
and poor wound healing. Laboratory evaluation reveals leukopenia and impaired
immune-cell function. The provider explains that normal host defense requires
coordinated activity among innate and adaptive immune mechanisms. Which
finding would most directly reflect impaired immune defense?
A. Increased oxygen-carrying capacity
B. Increased susceptibility to infection because of inadequate immune-cell
function
,2
C. Increased bone mineralization
D. Increased gastrointestinal motility
Answer: B
3.
A patient develops generalized urticaria, wheezing, hypotension, and facial
swelling shortly after receiving a medication. The symptoms develop rapidly and
involve multiple organ systems. Which pathophysiologic process best explains this
presentation?
A. Delayed T-cell-mediated tissue injury
B. Immune-complex deposition occurring over several weeks
C. Immediate hypersensitivity involving mast-cell mediator release
D. Autoimmune destruction of pancreatic beta cells
Answer: C
4.
A 65-year-old patient with long-standing cigarette exposure develops progressive
cough, weight loss, and hemoptysis. Imaging reveals a pulmonary mass. The
provider explains that malignant cells can acquire characteristics that allow
uncontrolled growth, invasion, and spread. Which cellular process most directly
contributes to malignant transformation?
A. Restoration of normal cell-cycle checkpoints
B. Increased dependence on normal apoptosis
C. Enhanced regulation of cellular proliferation
D. Accumulation of genetic alterations that disrupt normal growth regulation
Answer: D
5.
A patient presents with several days of vomiting and poor oral intake. Laboratory
testing shows elevated serum sodium and clinical findings consistent with
,3
intracellular dehydration. Which mechanism best explains the cellular changes
associated with significant hypernatremia?
A. Water shifts out of cells toward the relatively hypertonic extracellular
compartment
B. Sodium rapidly moves into cells and causes intracellular swelling
C. Potassium accumulation causes extracellular volume expansion
D. Intracellular fluid becomes hypertonic because plasma sodium decreases
Answer: A
6.
A 34-year-old patient develops progressive weakness, paresthesias, and muscle
cramps after prolonged use of a medication that increases urinary potassium
losses. Laboratory testing reveals significant hypokalemia. Which physiologic
consequence is most concerning?
A. Increased neuromuscular excitability caused exclusively by hypercalcemia
B. Altered membrane excitability that may produce muscle weakness and cardiac
dysrhythmias
C. Increased intracellular potassium caused by renal retention
D. Increased serum bicarbonate caused directly by potassium entering the
bloodstream
Answer: B
7.
A patient with severe diarrhea develops metabolic acidosis. Laboratory studies
demonstrate a decreased serum bicarbonate concentration. Which compensatory
response would the body initially use to reduce the impact of this acid-base
disturbance?
A. Decrease respiratory rate
B. Retain additional carbon dioxide
C. Increase alveolar ventilation to remove carbon dioxide
D. Suppress renal hydrogen-ion excretion permanently
, 4
Answer: C
8.
A patient with chronic obstructive pulmonary disease has a long history of carbon
dioxide retention. Arterial blood gas testing demonstrates elevated PaCO₂ and a
compensated pH. Which mechanism contributes to the chronic compensation?
A. Decreased renal bicarbonate reabsorption
B. Increased renal hydrogen retention
C. Complete suppression of respiratory drive
D. Increased renal bicarbonate retention to buffer excess acid
Answer: D
9.
A 29-year-old patient develops fever, localized swelling, warmth, erythema, and
pain after sustaining a contaminated wound. Which inflammatory process is
primarily responsible for the early vascular changes at the injured site?
A. Vasodilation and increased vascular permeability
B. Permanent destruction of all circulating leukocytes
C. Suppression of local blood flow
D. Decreased endothelial permeability
Answer: A
10.
A patient with a bacterial infection develops fever and leukocytosis. The provider
explains that inflammatory mediators communicate with the hypothalamus and
alter thermoregulation. Which mediator is strongly associated with the
development of fever during systemic inflammation?
A. Insulin
B. Pyrogenic cytokines that increase the hypothalamic temperature set point
C. Albumin
D. Erythropoietin
