1.
Which physiologic change is expected during starvation?
A. Increased insulin secretion
B. Increased gluconeogenesis
C. Enhanced glycogen storage
D. Reduced fatty acid utilization
Correct Answer: B
Rationale: The body increases gluconeogenesis to maintain glucose supply.
2.
A patient with chronic kidney disease develops anemia primarily due to:
A. Increased hemolysis
B. Reduced erythropoietin production
C. Iron deficiency from blood loss
D. Bone marrow suppression
Correct Answer: B
Rationale: Diseased kidneys produce less erythropoietin, reducing red blood cell production.

3.
Which mechanism best explains hyponatremia in heart failure?
A. Excessive sodium loss in urine
B. Increased aldosterone secretion alone
C. Dilutional effect from water retention
D. Decreased antidiuretic hormone secretion
Correct Answer: C
Rationale: Water retention exceeds sodium retention, leading to dilutional hyponatremia.
4.
A patient with chronic obstructive pulmonary disease develops respiratory acidosis. Which
compensatory response is expected?
A. Decreased bicarbonate reabsorption
B. Increased renal bicarbonate retention
C. Reduced hydrogen ion excretion
D. Increased respiratory rate
Correct Answer: B
Rationale: The kidneys compensate by retaining bicarbonate to buffer excess CO₂.

5.
Which hormone primarily stimulates erythropoiesis?
A. Thrombopoietin
B. Erythropoietin
C. Granulocyte colony-stimulating factor
D. Interleukin-6
Correct Answer: B
Rationale: Erythropoietin stimulates bone marrow red blood cell production.
6.
A patient with long-standing diabetes develops microalbuminuria. This finding indicates:
A. Advanced renal failure
B. Early diabetic nephropathy
C. Acute glomerulonephritis
D. Reversible renal injury
Correct Answer: B
Rationale: Microalbuminuria is an early marker of diabetic kidney disease.
