A patient is hyperventilating because of severe anxiety and develops respiratory alkalosis. Which renal response helps compensate?
Correct answer: B. Excreting more bicarbonate
- A. Retaining more bicarbonate
- B. Excreting more bicarbonate
- C. Retaining more hydrogen ions
- D. Excreting less sodium in urine
Explanation
During respiratory alkalosis, the kidneys excrete more bicarbonate to reduce the excess alkaline reserve and help lower blood pH toward normal. Hydrogen ion retention would worsen alkalosis rather than correct it.

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.
