Question 1
Which of the following describes the primary pathophysiology of Type 1
Diabetes Mellitus?
A) Insulin resistance in target tissues.
B) Increased hepatic glucose production.
C) Autoimmune destruction of pancreatic beta cells, leading to
absolute insulin deficiency.
D) Impaired insulin secretion due to pancreatic exhaustion.
E) Excessive glucagon production.
Correct Answer: C) Autoimmune destruction of pancreatic beta cells,
leading to absolute insulin deficiency.
Rationale: Type 1 diabetes is an autoimmune disease where the
body's immune system mistakenly attacks and destroys the insulin-
producing beta cells in the pancreas, resulting in a complete lack of
insulin production.
Question 2
A client with chronic kidney disease (CKD) develops anemia. This is primarily
due to:
A) Increased red blood cell destruction.
B) Decreased production of erythropoietin by the kidneys.
C) Iron deficiency from impaired absorption.
D) Folic acid deficiency from dietary restrictions.
E) Increased blood loss in urine.
Correct Answer: B) Decreased production of erythropoietin by the
kidneys.
Rationale: The kidneys produce erythropoietin, a hormone that
stimulates red blood cell production in the bone marrow. In CKD, the
damaged kidneys produce insufficient erythropoietin, leading to
normochromic, normocytic anemia.
Question 3
Which of the following is a classic symptom of right-sided heart failure?
A) Pulmonary edema and crackles.
B) Orthopnea and paroxysmal nocturnal dyspnea.
C) Peripheral edema and jugular venous distention (JVD).
D) Pink, frothy sputum.
,E) Decreased cardiac output.
Correct Answer: C) Peripheral edema and jugular venous distention
(JVD).
Rationale: Right-sided heart failure causes blood to back up into the
systemic venous circulation, leading to increased venous pressure
manifested as peripheral edema, JVD, hepatomegaly, and ascites.
Question 4
A client develops a deep vein thrombosis (DVT). The primary
pathophysiological process involves:
A) Arterial spasm and vasoconstriction.
B) Lymphedema and lymphatic obstruction.
C) Virchow's triad (venous stasis, endothelial injury,
hypercoagulability).
D) Arterial plaque rupture and thrombus formation.
E) Valvular incompetence in superficial veins.
Correct Answer: C) Virchow's triad (venous stasis, endothelial injury,
hypercoagulability).
Rationale: Virchow's triad describes the three main factors that
contribute to DVT formation: venous stasis (slowed blood flow),
endothelial injury (damage to the vessel lining), and
hypercoagulability (increased tendency for blood to clot).
Question 5
Which type of hepatitis is transmitted via the fecal-oral route and typically
causes an acute, self-limiting illness?
A) Hepatitis B.
B) Hepatitis C.
C) Hepatitis D.
D) Hepatitis A.
E) Hepatitis E (though also fecal-oral, Hep A is more common in this context).
Correct Answer: D) Hepatitis A.
Rationale: Hepatitis A virus (HAV) is primarily transmitted through
contaminated food or water (fecal-oral route) and typically causes
an acute, self-limiting infection that does not lead to chronic liver
disease.
Question 6
A client with acute pancreatitis develops severe abdominal pain radiating to
the back, nausea, vomiting, and elevated serum amylase and lipase levels.
This condition is characterized by:
, A) Gallstone obstruction of the common bile duct.
B) Autoimmune destruction of pancreatic islet cells.
C) Autodigestion of the pancreas by its own enzymes.
D) Inflammation of the gallbladder.
E) Bacterial infection of the pancreatic duct.
Correct Answer: C) Autodigestion of the pancreas by its own
enzymes.
Rationale: Acute pancreatitis is primarily caused by the premature
activation of pancreatic enzymes (e.g., trypsin) within the pancreas
itself, leading to the autodigestion of pancreatic tissue and
surrounding structures.
Question 7
Which of the following describes the pathophysiology of myasthenia gravis?
A) Demyelination of peripheral nerves.
B) Autoimmune destruction of acetylcholine receptors at the
neuromuscular junction.
C) Degeneration of motor neurons in the spinal cord.
D) Impaired dopamine production in the brain.
E) Inflammation of muscle fibers.
Correct Answer: B) Autoimmune destruction of acetylcholine
receptors at the neuromuscular junction.
Rationale: Myasthenia gravis is an autoimmune disorder where
antibodies block or destroy acetylcholine receptors at the
neuromuscular junction, preventing acetylcholine from binding and
causing muscle weakness.
Question 8
A client with untreated hypertension is at increased risk for left ventricular
hypertrophy. This is primarily due to:
A) Increased preload.
B) Increased afterload.
C) Decreased contractility.
D) Valvular stenosis.
E) Mitral regurgitation.
Correct Answer: B) Increased afterload.
Rationale: Hypertension increases the systemic vascular resistance,
which the left ventricle must overcome to eject blood. This
increased afterload forces the left ventricle to work harder, leading
to compensatory hypertrophy (enlargement of the muscle).
