A nurse is assessing a client after administering epinephrine for an anaphylactic reaction. Which of the following findings should the nurse identify as an adverse effect of this medication?

A. Hypotension is not an adverse effect of epinephrine, but rather a sign of anaphylaxis that epinephrine can help to reverse by causing vasoconstriction and increasing blood pressure. B. Report of tinnitus is not an adverse effect of epinephrine, but rather a symptom of aspirin toxicity, which can occur in some clients who take aspirin for allergic reactions. C. Report of chest pain is an adverse effect of epinephrine, as it can cause cardiac dysrhythmias, angina, and myocardial ischemia by increasing the heart rate and oxygen demand of the myocardium. D. Ecchymosis is not an adverse effect of epinephrine, but rather a sign of bleeding disorders or trauma that can cause bruising under the skin.
