Which action should the nurse take if Sarah reports difficulty swallowing after treatment?

A. Instruct her to take an antacid: Difficulty swallowing could be a sign of a more serious problem, such as esophageal irritation or a reaction to treatment. Taking an antacid may mask underlying issues, and it is not appropriate without further assessment. B. Notify the healthcare provider immediately: Difficulty swallowing after treatment may indicate a serious side effect or complication, such as esophageal damage, allergic reaction, or a swallowing disorder. Immediate evaluation by the healthcare provider is necessary to determine the cause and prevent further complications. C. Reassure her that this is expected: Difficulty swallowing after treatment should not be considered normal without investigation. It may indicate an issue that needs prompt attention to prevent further harm or discomfort. D. Encourage warm fluids: Encouraging fluids could be helpful in some cases of mild throat irritation, but it is not the first appropriate action. The nurse should prioritize notifying the healthcare provider to evaluate the cause of difficulty swallowing.
