A nurse is caring for a client who has a history of angina.​​​​​​ Exhibits Which of the following findings require follow-up by the nurse? Select all that apply.

A. The client’s BP increased significantly from 150/80 to 180/86 mm Hg, which can indicate increased cardiac workload or evolving cardiac ischemia. B. Anxiety in this context may be a sign of worsening cardiac status or an early symptom of myocardial infarction (MI). C. The oxygen saturation is 95%, which is within normal limits and not concerning at this point. D. Breath sounds are clear and unchanged from the earlier assessment, suggesting no immediate respiratory compromise. E. The heart rate became irregular and increased to 112/min, which could indicate a dysrhythmia or cardiac ischemia. F. Chest tightness radiating to the jaw and not relieved by rest is a classic sign of myocardial infarction and should be treated as a medical emergency.
