1. Question: A patient presents with elevated levels of aldosterone. Which of the following is most likely
a consequence of this condition?

A) Decreased sodium reabsorption
B) Hyperkalemia
C) Increased potassium secretion
D) Hypotension

Answer: C) Increased potassium secretion

Rationale:
Aldosterone is a mineralocorticoid hormone that promotes sodium retention and potassium excretion in
the kidneys. When aldosterone levels are elevated, sodium reabsorption increases, leading to water
retention, and potassium secretion is enhanced, which can result in hypokalemia, not hyperkalemia.



2. Question: A patient with chronic kidney disease (CKD) is found to have elevated parathyroid hormone
(PTH) levels. What is the most likely reason for this finding?

A) Decreased calcium absorption from the gut
B) Increased renal synthesis of vitamin D
C) Increased calcium excretion
D) Decreased phosphate excretion

Answer: D) Decreased phosphate excretion

Rationale:
In CKD, the kidneys' ability to excrete phosphate is impaired, leading to elevated serum phosphate levels.
High phosphate levels stimulate the release of parathyroid hormone (PTH) in an attempt to normalize
calcium and phosphate balance. This is part of the pathophysiology of secondary hyperparathyroidism
seen in CKD.



3. Question: Which of the following mechanisms is primarily responsible for the development of
pulmonary edema in left-sided heart failure?

A) Increased pulmonary blood flow
B) Increased capillary permeability
C) Decreased lymphatic drainage
D) Increased left atrial pressure

Answer: D) Increased left atrial pressure

Rationale:
In left-sided heart failure, the left ventricle’s reduced pumping efficiency leads to increased pressure in
the left atrium. This elevated pressure is transmitted backward to the pulmonary veins and capillaries,
causing fluid to accumulate in the alveoli, resulting in pulmonary edema.

,4. Question: In acute pancreatitis, what is the primary cause of the activation of pancreatic enzymes
within the pancreas?

A) Deficient bile flow
B) Decreased bicarbonate secretion
C) Early activation of trypsinogen to trypsin
D) Increased pancreatic blood flow

Answer: C) Early activation of trypsinogen to trypsin

Rationale:
In acute pancreatitis, the normal process of pancreatic enzyme activation is disrupted, and trypsinogen is
prematurely activated to trypsin within the pancreas. Trypsin then activates other digestive enzymes,
leading to pancreatic autodigestion and inflammation.



5. Question: Which of the following is the most common cause of chronic gastritis?

A) Autoimmune destruction of parietal cells
B) Helicobacter pylori infection
C) Nonsteroidal anti-inflammatory drug (NSAID) use
D) Alcohol consumption

Answer: B) Helicobacter pylori infection

Rationale:
The most common cause of chronic gastritis is infection with Helicobacter pylori, a bacterium that
colonizes the stomach lining and leads to chronic inflammation, mucosal damage, and increased risk of
peptic ulcer disease and gastric cancer.



6. Question: Which of the following laboratory findings is most characteristic of hyperthyroidism?

A) Low serum TSH and high free T4
B) High serum TSH and low free T4
C) High serum TSH and high free T4
D) Low serum TSH and low free T4

Answer: A) Low serum TSH and high free T4

Rationale:
In hyperthyroidism, excessive thyroid hormone (T4) is produced, which suppresses the release of
thyroid-stimulating hormone (TSH) from the pituitary gland via negative feedback. As a result, serum TSH
levels are low, while free T4 levels are elevated.



7. Question: A patient with cirrhosis develops jaundice. What is the primary mechanism responsible for
this condition?

, A) Decreased bilirubin production
B) Decreased bilirubin conjugation
C) Increased bilirubin excretion
D) Impaired bile secretion

Answer: B) Decreased bilirubin conjugation

Rationale:
In cirrhosis, liver function is impaired, leading to decreased conjugation of bilirubin. This results in the
accumulation of unconjugated bilirubin in the bloodstream, causing jaundice.



8. Question: Which of the following is a common cause of secondary hypertension?

A) Hyperaldosteronism
B) Essential hypertension
C) Stress
D) High-salt diet

Answer: A) Hyperaldosteronism

Rationale:
Secondary hypertension is caused by an underlying condition, such as hyperaldosteronism, which leads
to increased aldosterone levels and sodium retention, thereby increasing blood volume and blood
pressure. Essential hypertension, on the other hand, is idiopathic and not due to another disease.



9. Question: Which of the following best describes the pathophysiology of Type 1 diabetes mellitus?

A) Insulin resistance due to obesity
B) Autoimmune destruction of pancreatic beta cells
C) Decreased sensitivity of the liver to insulin
D) Impaired glucose absorption in the intestines

Answer: B) Autoimmune destruction of pancreatic beta cells

Rationale:
In Type 1 diabetes mellitus, an autoimmune process destroys the pancreatic beta cells, which are
responsible for producing insulin. This leads to an insulin deficiency and impaired glucose regulation,
often resulting in hyperglycemia.



10. Question: A patient with untreated chronic obstructive pulmonary disease (COPD) is at risk for
developing respiratory acidosis. Which of the following mechanisms is responsible for this condition?

A) Increased elimination of CO2 through the lungs
B) Hypoventilation leading to CO2 retention
