1. What is a key characteristic of Crohn's disease?
A. Continuous inflammation of the colon
B. Painless, non-bloody diarrhea
C. Skip lesions along the gastrointestinal tract
D. Gallstone formation
Answer: C) Skip lesions along the gastrointestinal tract
Rationale: Crohn’s disease is characterized by inflammation that
can occur in patches (skip lesions) throughout the gastrointestinal
tract, leading to symptoms like diarrhea, abdominal pain, and
weight loss.
2. What is the main cause of type 2 diabetes?
A. Insulin resistance
B. Insulin deficiency
C. Autoimmune destruction of beta cells
D. Excessive glucagon secretion
Answer: A) Insulin resistance
Rationale: Type 2 diabetes is primarily caused by insulin
resistance, where the body’s cells do not respond effectively to
insulin, leading to elevated blood glucose levels.
3. A patient is being treated for acute pancreatitis. What is a
common complication of this condition?
A. Renal failure
B. Chronic diarrhea
C. Hyperglycemia
D. Gallstones
Answer: A) Renal failure
Rationale: Acute pancreatitis can lead to systemic complications,
including renal failure, due to inflammation and the release of
digestive enzymes into the bloodstream.
,4. What is the primary cause of atherosclerosis?
A. Decreased calcium intake
B. Chronic inflammation of the blood vessels
C. Increased HDL cholesterol
D. Vitamin D deficiency
Answer: B) Chronic inflammation of the blood vessels
Rationale: Atherosclerosis is primarily caused by the build-up of
plaque in the arteries, often triggered by chronic inflammation
and high levels of LDL cholesterol in the bloodstream.
5. What is the most common cause of secondary osteoporosis?
A. Calcium deficiency
B. Hyperparathyroidism
C. Long-term use of corticosteroids
D. Vitamin D deficiency
Answer: C) Long-term use of corticosteroids
Rationale: Long-term corticosteroid use is a major cause of
secondary osteoporosis due to its effect on bone metabolism,
leading to decreased bone density and increased fracture risk.
6. What is a classic symptom of Parkinson’s disease?
A. Muscle rigidity
B. Hypotension
C. Polyuria
D. Weight gain
Answer: A) Muscle rigidity
Rationale: Parkinson’s disease is characterized by symptoms such
as muscle rigidity, tremors, and bradykinesia due to a loss of
dopaminergic neurons in the brain.
7. What is the most common cause of peptic ulcers?
A. Stress
, B. Use of nonsteroidal anti-inflammatory drugs (NSAIDs)
C. Helicobacter pylori infection
D. Excessive alcohol consumption
Answer: C) Helicobacter pylori infection
Rationale: H. pylori infection is the leading cause of peptic ulcers
due to its ability to disrupt the mucosal lining of the stomach.
8. Which of the following lab findings is typically seen in a patient
with acute renal failure (ARF)?
A. Increased serum creatinine
B. Decreased serum potassium
C. Decreased blood urea nitrogen (BUN)
D. Decreased urine output (oliguria)
Answer: A) Increased serum creatinine
Rationale: In acute renal failure, the kidneys' ability to excrete
waste products diminishes, leading to an increase in serum
creatinine levels.
9. A patient with chronic kidney disease (CKD) is most at risk for
which of the following electrolyte imbalances?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypocalcemia
Answer: A) Hyperkalemia
Rationale: In CKD, the kidneys are unable to excrete potassium
effectively, leading to the accumulation of potassium in the blood,
resulting in hyperkalemia.
10. A patient with COPD has developed a barrel chest. What does
this physical finding indicate?
A. Emphysema
B. Pneumonia
A. Continuous inflammation of the colon
B. Painless, non-bloody diarrhea
C. Skip lesions along the gastrointestinal tract
D. Gallstone formation
Answer: C) Skip lesions along the gastrointestinal tract
Rationale: Crohn’s disease is characterized by inflammation that
can occur in patches (skip lesions) throughout the gastrointestinal
tract, leading to symptoms like diarrhea, abdominal pain, and
weight loss.
