5 Questions
What is the primary characteristic of renal tubular acidosis (RTA)?
Decrease in the H+ excreted in the urine
Which type of RTA is characterized by an inability to secrete H+ at the distal tubule?
Type 1 RTA
What is the consequence of distal RTA leading to increased excretion of ions?
Hypokalemia
What is the characteristic metabolic acidosis associated with distal RTA?
Hypokalemic, hyperchloremic metabolic acidosis
What are the symptoms primarily associated with distal RTA?
Nephrocalcinosis
Study Notes
Renal Tubular Acidosis (RTA)
- Primary characteristic of RTA: impaired renal acid-base regulation
- Impaired ability to excrete H+ or reabsorb HCO3- in the kidneys
Distal RTA
- Characterized by inability to secrete H+ at the distal tubule
- Consequence of distal RTA: increased excretion of ions, particularly potassium, calcium, and magnesium
- Metabolic acidosis associated with distal RTA: non-anion gap (normal anion gap) metabolic acidosis
- Symptoms primarily associated with distal RTA: muscle weakness, fatigue, and hypokalemia (low potassium levels)
Test your knowledge about the general characteristics of renal tubular acidosis, a disorder of the renal tubules that leads to metabolic acidosis. Learn about the different types and mechanisms of RTA.
