A client is currently taking bismuth subsalicylate (Pepto-Bismol) to help with diarrhea. The nurse would educate the client on which adverse effect associated with bismuth subsalicylate?

Choice A reason: Hypotension is not a known adverse effect of bismuth subsalicylate. This medication primarily affects the gastrointestinal system and does not typically influence blood pressure. Choice B reason: Blood clots are not associated with bismuth subsalicylate use. This medication does not have effects on coagulation or blood clotting mechanisms. Choice C reason: Hypoglycemia is not a side effect of bismuth subsalicylate. It does not impact blood glucose levels, and clients do not need to be concerned about hypoglycemia when taking this medication. Choice D reason: Tongue discoloration is a common and benign side effect of bismuth subsalicylate. The medication can cause the tongue and stool to turn black temporarily. Clients should be informed about this effect to prevent unnecessary concern.
