A nurse is administering spironolactone at 0800 to a client who has heart failure.The nurse should monitor the client for which of the following adverse effects?

Choice A rationale:Hypernatremia (high sodium levels) is not a common side effect of spironolactone. Spironolactone is a potassium-sparing diuretic and does not typically affect sodium levels.Choice B rationale:Hyperkalemia (high potassium levels) is a potential adverse effect of spironolactone. As a potassium-sparing diuretic, spironolactone can cause an increase in serum potassium levels.Choice C rationale:Hypophosphatemia (low phosphate levels) is not typically associated with spironolactone use.Choice D rationale:Hypocalcemia (low calcium levels) is also not a common side effect of spironolactone.
