Help with acid-base

I think you need to go back and review your text and notes on acid-base imbalances. Also review in your pharm book what effect sodium bicarbonate has on the body as well as what it is used to treat.

Giving you the answer here isn't going to help you understand and know this topic.

I already know the answer and looked it up but I don't understand it.

I'm doing this NCLEX practice questions and I'm confused with it.

Q: A hospitalized client asks the nurse for sodium bicarbonate to relieve heartburn following a meal. The nurse reviews the client's medical record, knowing that the medication is contraindicated in w/c of the following conditions?

The answer was: Metablic alkalosis when I thought its respiratory acidosis. Help //??

" Administration of sodium bicarbonate in amounts that exceed the capacity of the kidneys to excrete this excess bicarbonate may cause metabolic alkalosis. This capacity is reduced when a reduction in filtered bicarbonate occurs, as observed in renal failure, or when enhanced tubular reabsorption of bicarbonate occurs, as observed in volume depletion"
