A patient who swallowed a large amount of aspirin has tinnitus, rapid breathing and a rising blood pH. Which treatment helps enhance salicylate elimination by alkalinising the urine?
Correct answer: A. Sodium bicarbonate
- A. Sodium bicarbonate
- B. Calcium gluconate
- C. Naloxone
- D. Atropine sulfate
Explanation
Intravenous sodium bicarbonate alkalinises serum and urine, increasing salicylate ionisation and renal elimination. It also requires monitoring of electrolytes, fluid status and acid base balance; naloxone and atropine do not treat salicylate poisoning.
