Chapter 1: Introduction to Pathophysiology
Question 1: A patient's laboratory report indicates a serum potassium level of 5.8
mEq/L. Which term best describes this finding?
A. Hypokalemia
B. Hyperkalemia
C. Normokalemia
D. Hypocalcemia
Correct Answer: B
Rationale: The normal serum potassium range is approximately 3.5–5.0
mEq/L. A value of 5.8 mEq/L exceeds the upper limit of normal and is therefore
termed hyperkalemia. Hypokalemia refers to a low potassium level.
Normokalemia indicates a normal level. Hypocalcemia refers to low calcium, not
potassium.
Question 2: Which of the following best defines the term pathogenesis?
A. The cause of a disease
B. The development and progression of a disease process
C. The subjective experience of a disease
D. The predicted outcome of a disease
Correct Answer: B
Rationale: Pathogenesis refers to the sequence of cellular and tissue
events that occur from the initial contact with an etiologic agent until the ultimate
expression of disease. Etiology is the cause. A symptom is a subjective experience.
Prognosis is the predicted outcome.
,Question 3: A patient reports a throbbing headache that began after a stressful
meeting. The headache is an example of which of the following?
A. An objective finding
B. A sign
C. A symptom
D. A syndrome
Correct Answer: C
Rationale: A symptom is a subjective complaint reported by the patient,
such as pain, nausea, or fatigue. A sign is an objective, measurable finding (e.g.,
fever, rash). A syndrome is a collection of signs and symptoms that occur together
and characterize a specific condition.
Question 4: Which of the following are examples of iatrogenic conditions? Select
all that apply.
A. A surgical wound infection acquired in the hospital
B. A rash caused by a prescribed antibiotic
C. A genetic disorder present at birth
D. A nerve injury resulting from a misplaced injection
E. A fracture caused by a fall at home
Correct Answer: A, B, D
Rationale: Iatrogenic conditions are unintended adverse effects resulting
from medical treatment or procedures. Hospital-acquired infections, drug
reactions to prescribed medications, and procedure-related injuries are all
iatrogenic. A genetic disorder is congenital, not iatrogenic. A fall at home is an
accidental injury unrelated to medical care.
Question 5: A patient with a known history of diabetes mellitus develops a foot
ulcer. In this scenario, diabetes mellitus is best described as which of the
following?
A. A predisposing factor
B. A precipitating factor
,C. A complication
D. A sequela
Correct Answer: A
Rationale: A predisposing factor increases the likelihood that a disease or
condition will develop. Diabetes mellitus predisposes a patient to poor wound
healing and ulcer formation due to neuropathic and vascular changes. A
precipitating factor triggers the onset of a condition. A complication is a new
problem arising from a disease. A sequela is a long-term consequence of a disease
or injury.
Question 6: Which of the following statements accurately describe prevention in
the context of pathophysiology? Select all that apply.
A. Primary prevention aims to reduce risk factors before disease occurs.
B. Secondary prevention focuses on early detection and treatment.
C. Tertiary prevention aims to restore function after significant damage has
occurred.
D. Quaternary prevention refers to rehabilitation after a stroke.
Correct Answer: A, B, C
Rationale: Primary prevention (e.g., vaccination, smoking cessation) aims
to prevent disease before it occurs. Secondary prevention (e.g., screening
mammography) focuses on early detection to halt disease progression. Tertiary
prevention (e.g., cardiac rehabilitation) aims to restore function and minimize
disability after disease has caused damage. Quaternary prevention is not a
standard classification in this context and rehabilitation after a stroke falls under
tertiary prevention.
Question 7: A 68-year-old patient has a BMI of 32 and a sedentary lifestyle. These
factors are best classified as which of the following?
A. Clinical manifestations
B. Risk factors
C. Diagnostic criteria
D. Therapeutic targets
, Correct Answer: B
Rationale: Risk factors are characteristics or exposures that increase the
probability of developing a disease. Obesity (BMI >30) and physical inactivity are
modifiable risk factors for numerous conditions, including cardiovascular disease
and type 2 diabetes. They are not clinical manifestations (which are
signs/symptoms), diagnostic criteria, or therapeutic targets in themselves.
Chapter 2: Fluid, Electrolyte, and Acid–Base Imbalances
Question 8: A patient has a serum sodium level of 118 mEq/L and presents with
confusion and seizures. Which fluid shift is most likely responsible for these
neurological symptoms?
A. Intracellular fluid moving into the extracellular space
B. Extracellular fluid moving into the intracellular space
C. Interstitial fluid moving into the plasma
D. Plasma moving into the interstitial space
Correct Answer: B
Rationale: Severe hyponatremia (serum sodium <120 mEq/L) creates a
hypotonic extracellular environment. Water moves by osmosis from the
extracellular compartment into the intracellular compartment, causing cellular
swelling. In the brain, this cerebral edema leads to confusion, seizures, and
potentially life-threatening increased intracranial pressure.
Question 9: Which of the following conditions is most likely to cause
hypokalemia?
A. Renal failure
B. Excessive use of loop diuretics
C. Adrenal insufficiency
D. Metabolic acidosis
Correct Answer: B
