A male client reports to the on-call clinic nurse that he took tadalafil 10 mg by mouth two hours ago and his skin now feels flushed. He reports a history of stable angina but denies experiencing any current or recent chest pain. Which action should the nurse take?

- A: Nitroglycerin is contraindicated with tadalafil due to the risk of severe hypotension. Advising the client to take nitroglycerin could lead to a dangerous drop in blood pressure. - B: While it is important to monitor for serious side effects, immediate emergency department care may not be necessary if the client is not experiencing chest pain or other severe symptoms. - C: Increasing oral fluids does not address the underlying cause of the skin flushing and is not a recommended action for this symptom in relation to tadalafil use. - D: Skin flushing is a common side effect of tadalafil and is usually self-limiting. Reassuring the client about the nature of this side effect is appropriate, as long as the client is not experiencing chest pain or other severe symptoms related to his history of stable angina.
