A patient with type 1 diabetes mellitus presents with fruity breath odor, Kussmaul
respirations, and glucose of 520 mg/dL. What is the primary pathophysiologic process?
a. Excess insulin production
b. Absolute insulin deficiency leading to ketone production
c. Increased glucagon suppression
d. Decreased cortisol secretion
✔️ Correct Answer: B
Rationale:
Diabetic ketoacidosis occurs due to absolute insulin deficiency, leading to lipolysis and
ketone production, causing metabolic acidosis and compensatory Kussmaul respirations.
NCLEX focus: endocrine pathophysiology and DKA mechanisms.
A patient develops edema and ascites due to liver cirrhosis. What is the primary
mechanism?
a. Increased albumin production
b. Decreased plasma oncotic pressure
,c. Increased red blood cell production
d. Increased antidiuretic hormone breakdown
✔️ Correct Answer: B
Rationale:
Cirrhosis reduces albumin synthesis, lowering oncotic pressure and causing fluid shift
into interstitial spaces. NCLEX focus: hepatic pathophysiology and cirrhosis
complications.
A patient with heart failure has increased preload. What physiologic change contributes
most?
a. Increased ventricular contractility
b. Fluid retention due to RAAS activation
c. Decreased sympathetic stimulation
d. Increased renal sodium loss
✔️ Correct Answer: B
Rationale:
Heart failure activates RAAS, leading to sodium and water retention, increasing preload
and worsening congestion. NCLEX focus: cardiovascular pathophysiology and RAAS in
heart failure.
A patient has asthma. What is the primary pathophysiologic mechanism?
a. Alveolar destruction
b. Reversible airway inflammation and bronchoconstriction
c. Fibrotic lung remodeling
d. Pulmonary vascular collapse
✔️ Correct Answer: B
Rationale:
Asthma involves reversible airway inflammation, hyperresponsiveness, and
bronchoconstriction. NCLEX focus: respiratory pathophysiology and asthma mechanism.
,A patient with COPD has chronic hypoxemia. What is the primary cause?
a. Reversible airway obstruction
b. Alveolar wall destruction and ventilation-perfusion mismatch
c. Increased surfactant production
d. Pulmonary embolism
✔️ Correct Answer: B
Rationale:
COPD (especially emphysema) causes alveolar destruction, reducing gas exchange and
causing V/Q mismatch. NCLEX focus: COPD pathophysiology and hypoxemia.
A patient develops metabolic alkalosis after prolonged vomiting. What is the
mechanism?
a. Loss of bicarbonate
b. Loss of gastric acid (HCl)
c. Increased lactic acid production
d. Renal failure
✔️ Correct Answer: B
Rationale:
Vomiting removes hydrogen ions (acid), increasing serum bicarbonate relative
concentration, causing alkalosis. NCLEX focus: acid-base disorders and metabolic
alkalosis.
A patient with chronic kidney disease develops anemia. What is the primary cause?
a. Excess iron intake
b. Decreased erythropoietin production
c. Increased vitamin K breakdown
d. Increased platelet production
, ✔️ Correct Answer: B
Rationale:
Diseased kidneys produce less erythropoietin, leading to decreased RBC production and
anemia. NCLEX focus: renal pathophysiology and CKD anemia.
A patient has increased intracranial pressure (ICP). What is the most likely early
compensatory response?
a. Increased heart rate and hypertension
b. Decreased cerebral perfusion
c. Loss of consciousness immediately
d. Bradycardia and hypotension
✔️ Correct Answer: A
Rationale:
Early Cushing response includes increased blood pressure and bradycardia as ICP rises,
initially attempting to maintain perfusion. NCLEX focus: neurologic pathophysiology and
ICP compensation.
A patient with septic shock has hypotension despite fluid resuscitation. What is the
underlying mechanism?
a. Increased systemic vascular resistance
b. Vasodilation from inflammatory mediators
c. Increased cardiac contractility
d. Increased blood viscosity
✔️ Correct Answer: B
Rationale:
Sepsis causes release of cytokines leading to widespread vasodilation and capillary leak.
NCLEX focus: shock states and septic shock.
