life-threatening cardiac complication?
A. Reduced renal potassium excretion causing extracellular potassium
accumulation
B. Increased renal bicarbonate generation
C. Increased phosphate excretion
D. Increased erythropoietin secretion
Answer: A
10. A patient with chronic kidney disease develops secondary
hyperparathyroidism. Which combination of abnormalities most strongly
contributes to this endocrine response?
A. Hypercalcemia and increased calcitriol production
B. Hyperphosphatemia, reduced calcitriol production, and decreased serum
calcium
C. Hypophosphatemia and increased intestinal calcium excretion
D. Increased renal activation of vitamin D and suppression of parathyroid
hormone
Answer: B
pg. 3
, 11. A patient develops metabolic acidosis from severe diarrhea. Which renal
response would normally help compensate for the acid-base disturbance?
A. Increased bicarbonate excretion
B. Reduced hydrogen ion secretion
C. Increased hydrogen ion secretion and generation of new bicarbonate
D. Reduced ammonium production
Answer: C
12. A patient with persistent vomiting develops metabolic alkalosis. Which
physiologic mechanism contributes to maintenance of this disturbance?
A. Increased gastric acid production with immediate renal elimination
B. Excessive bicarbonate excretion caused by volume expansion
C. Increased intracellular hydrogen ion concentration
D. Volume depletion and chloride loss impairing renal bicarbonate excretion
Answer: D
13. A patient with diabetic ketoacidosis has a serum pH of 7.18 and develops
deep, rapid respirations. What is the primary purpose of this respiratory
response?
A. To increase carbon dioxide elimination and partially compensate for
metabolic acidosis
B. To increase bicarbonate production in the lungs
C. To decrease oxygen consumption by respiratory muscles
D. To retain carbon dioxide and increase blood acidity
Answer: A

hypercapnia. Which renal adaptation is expected with chronic respiratory
acidosis?
