A patient has respiratory acidosis caused by hypoventilation. Which renal response supports correction of the acid-base disturbance?
Correct answer: A. Excreting hydrogen ions and retaining bicarbonate
- A. Excreting hydrogen ions and retaining bicarbonate
- B. Retaining hydrogen ions and excreting bicarbonate
- C. Reducing ammonium formation in the tubules
- D. Preventing reabsorption of filtered bicarbonate
Explanation
In respiratory acidosis, the kidneys compensate by increasing hydrogen ion excretion and conserving or generating bicarbonate. The opposite responses would increase acidity and worsen the patient's imbalance.

About Urinary System
The urinary system includes the kidneys, ureters, urinary bladder and urethra, with emphasis on nephron structure and urine formation. It explains glomerular filtration, tubular reabsorption, tubular secretion, water and electrolyte regulation, acid base balance, and the roles of ADH and aldosterone in maintaining homeostasis.
