Pathophysiology (Questions 1–75)
1. A patient with chronic obstructive pulmonary disease (COPD) presents with worsening dyspnea and a
productive cough. Which pathophysiological mechanism is primarily responsible for the airflow
limitation in this patient?
A) Destruction of alveolar walls leading to decreased surface area for gas exchange
B) Airway inflammation, mucus hypersecretion, and airway wall thickening
C) Pulmonary vasoconstriction leading to increased pulmonary artery pressure
D) Decreased surfactant production causing alveolar collapse
Answer: B Airflow limitation in COPD results from a combination of airway inflammation, mucus
hypersecretion, and airway wall thickening. While alveolar destruction occurs in emphysema, th e
primary mechanism involves chronic inflammation and structural changes in the airways.
2. A 65yearold male with a history of hypertension presents with sudden onset of severe chest pain
radiating to his back. Which condition should the nurse practitioner suspect?
A) Myocardial infarction
B) Pulmonary embolism
C) Aortic dissection
D) Pericarditis
Answer: C Aortic dissection typically presents with sudden, severe chest pain that radiates to the back.
The pain is often described as tearing or ripping in nature. Hypertension is a major risk factor.
,3. Which of the following is the most common cause of acute pancreatitis?
A) Hyperlipidemia
B) Gallstones
C) Alcohol abuse
D) Trauma
Answer: B Gallstones are the most common cause of acute pancreatitis, followed by alcohol abuse.
Gallstones can obstruct the pancreatic duct, leading to enzyme activation and autodigestion of the
pancreas.
4. A patient with type 1 diabetes mellitus presents with fruity breath odor, Kussmaul re spirations, and
confusion. Which condition is most likely?
A) Hypoglycemia
B) Diabetic ketoacidosis (DKA)
C) Hyperglycemic hyperosmolar state (HHS)
D) Lactic acidosis
Answer: B Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic
acidosis. Fruity breath odor (acetone) and Kussmaul respirations (deep, rapid breathing) are classic
signs.
5. A patient with chronic kidney disease (CKD) is found to have elevated serum phosphorus and
decreased serum calcium levels. Which compensatory mechanism is activated?
A) Increased calcitonin secretion
B) Decreased parathyroid hormone (PTH) secretion
,C) Increased parathyroid hormone (PTH) secretion
D) Decreased vitamin D activation
Answer: C In CKD, hyperphosphatemia and hypocalcemia stimulate increased PTH secretion (secondary
hyperparathyroidism). The kidneys fail to activate vitamin D, leading to decreased calcium absorption.
6. Which of the following best describes the pathophysiology of iron deficiency anemia?
A) Decreased production of erythropoietin
B) Insufficient iron stores leading to decreased hemoglobin synthesis
C) Autoimmune destruction of red blood cells
D) Genetic mutation affecting hemoglobin structure
Answer: B Iron deficiency anemia results from insufficient iron stores, which impairs hemoglobin
synthesis. This leads to microcytic, hypochromic red blood cells.
7. A patient with liver cirrhosis presents with ascites, esophageal varices, and splenomegaly. Which
pathophysiological process is primarily responsible for these findings?
A) Decreased albumin production leading to decreased oncotic pressure
B) Portal hypertension leading to increased hydrostatic pressure in the splanchnic circulation
C) Increased aldosterone secretion leading to sodium and water retention
D) All of the above
Answer: D All of these mechanisms contribute to the complications of liver cirrhosis. Portal
hypertension increases hydrostatic pressure, decreased albumin reduces oncotic pressure, and
increased aldosterone causes sodium and water retention.
, 8. A 45yearold female presents with fatigue, weight gain, cold intolerance, and dry skin. Laboratory
findings show elevated TSH and low free T4. Which condition is most likely?
A) Hyperthyroidism
B) Hypothyroidism
C) Thyroiditis
D) Graves' disease
Answer: B Primary hypothyroidism is characterized by elevated TSH and low free T4 levels. Symptoms
include fatigue, weight gain, cold intolerance, and dry skin.
9. A patient with rheumatoid arthritis is at increased risk for which of the following extraarticular
manifestations?
A) Pericarditis
B) Sjögren's syndrome
C) Rheumatoid nodules
D) All of the above
Answer: D Rheumatoid arthritis can affect multiple organ systems. Extraarticular manifestations include
pericarditis, Sjögren's syndrome (dry eyes and mouth), and rheumatoid nodules.
10. Which of the following is the most common cause of bacterial meningitis in adults?
A) Neisseria meningitidis
B) Streptococcus pneumoniae
C) Haemophilus influenzae
