Pathophysiology Final Exam Questions
and Answers 2024 – 2026 | Rasmussen
Q1. Which of the following is part of the pathophysiology leading to the
appearance of a barrel chest?
• A. Peripheral edema
• B. Bacterial infection in the lungs
• C. Air trapping in the alveoli
• D. Muscle atrophy of the diaphragm
Rationale: Barrel chest results from chronic air trapping (e.g., COPD,
emphysema) due to loss of elastic recoil and hyperinflation of the lungs, increasing
the anteroposterior diameter.
Q2. The primary problem with anemia, regardless of the cause, is to ______.
• A. Occult bleeding reduces the hemoglobin and hematocrit
• B. Tissue hypoxia; restore tissue oxygenation
• C. Tissue hyperoxia; have the patient breathe
• D. Oxygen saturation more than 100% reduces oxygen
Rationale: Anemia reduces oxygen-carrying capacity, leading to tissue hypoxia.
The goal of treatment is to restore adequate tissue oxygenation.
Q3. Intracellular fluid contains a higher concentration of ______.
• A. Magnesium
• B. Sodium
• C. Chloride
• D. Bicarbonate
pg. 1
,2
Rationale: Intracellular fluid has high potassium, magnesium, and phosphate.
Extracellular fluid has high sodium, chloride, and bicarbonate.
Q4. Which of the following is a characteristic of disseminated intravascular
coagulation (DIC)?
• A. Simultaneous stroke and heart attack
• B. Simultaneous clotting and bleeding
• C. Isolated venous thrombosis
• D. Isolated arterial thrombosis
Rationale: DIC is characterized by widespread activation of coagulation leading to
microthrombi, consumption of platelets and clotting factors, and subsequent
bleeding.
Q5: Which of the following conditions is most directly associated with
intravascular hemolysis?
• A. Vascular spasm
• B. Platelet aggregation
• C. Coagulation cascade activation
• D. Complement activation on red blood cells
Rationale: Intravascular hemolysis occurs when complement proteins (e.g., in
transfusion reactions, paroxysmal nocturnal hemoglobinuria) directly lyse RBCs.
Q6. Which of the following clinical findings would be expected to be present in a
patient with acute hemolytic anemia?
• A. Altered level of consciousness
• B. Hypotension
• C. Increased mental clarity
• D. Tachycardia
pg. 2
,3
• E. Hypertension
Rationale: Acute hemolytic anemia causes tissue hypoxia, leading to
compensatory tachycardia. Hypotension and altered mental status may occur in
severe cases, but tachycardia is an early, consistent finding.
Q7. Which of the following describes the pathophysiology of hemolytic anemia?
• A. Demyelination of neurons in the central nervous system
• B. Decreased production of dopamine in the central nervous system
• C. Destruction of red blood cells (premature)
• D. Destruction of acetylcholine receptors on muscle cells
Rationale: Hemolytic anemia results from premature destruction of RBCs, either
intravascularly or extravascularly (spleen/liver).
Q8. Which of the following is a component of elevated intracranial pressure (ICP)?
• A. Decreased plasma proteins
• B. Hypotension
• C. Dehydration
• D. Polyuria (late sign, from diabetes insipidus due to pituitary
compression)
Rationale: Elevated ICP can cause Cushing's triad (hypertension, bradycardia,
irregular respirations). Polyuria may occur late from pituitary stalk compression
causing diabetes insipidus. Decreased plasma proteins, hypotension, and
dehydration are not direct components.
Q9. Signs and symptoms of myocardial infarction include:
• A. Persistent chest pain which may radiate to the arm, neck, or jaw
• B. Brief sternal chest pain on inspiration
• C. Rapid respiration with left-sided weakness and nausea
pg. 3
, 4
• D. Left upper quadrant abdominal pain which radiates to the left shoulder
Rationale: MI classically presents with substernal chest pain radiating to left arm,
neck, jaw, or back. Pain on inspiration suggests pericarditis. Left-sided weakness
suggests stroke.
Q10. Which of the following can lead to impaired neurological function?
• A. Compression of the brain
• B. Inflammation of the brain tissue
• C. Decreased perfusion of the brain tissue
• D. The inability of the tissues to autoregulate pressure
• E. All of the above
Rationale: Compression (tumor, edema), inflammation (meningitis, encephalitis),
decreased perfusion (stroke, shock), and loss of autoregulation (hypertensive
encephalopathy) all impair neurological function.
Q11. Increased calcium levels in the blood could be associated with which of the
following hormones?
• A. Parathyroid hormone (PTH)
• B. Antidiuretic hormone (ADH)
• C. Calcitonin
• D. Melatonin
Rationale: PTH increases serum calcium by bone resorption, renal reabsorption,
and intestinal absorption. Calcitonin decreases calcium.
Q12. Which hyperglycemic disorder is related to energy crisis in patients with type
1 diabetes?
• A. Nonketotic hyperglycemic hyperosmolar syndrome (HHNS)
• B. Hyperglycemic lipid syndrome
