An adult with a history of cardiovascular disease comes to the clinic complaining of indigestion. Vital signs are heart rate 130 beats/minute, respirations 24 breaths/minute, and blood pressure 180/90 mm/Hg. Which finding should the practical nurse (PN) report immediately to the healthcare provider?

A. Severe headache: While concerning, a headache alone in this context may indicate hypertension or stress, but it is not as immediately life-threatening as potential cardiac ischemia. It should be assessed, but reporting is not the most urgent action. B. Left jaw discomfort: Discomfort in the left jaw is a classic sign of myocardial ischemia or acute coronary syndrome, particularly in a client with a history of cardiovascular disease. Immediate reporting is essential to initiate prompt evaluation and treatment to prevent complications such as myocardial infarction. C. Nausea with emesis: Nausea can accompany cardiac events, but by itself it is a nonspecific symptom. It requires monitoring but is not as urgent as signs of potential cardiac ischemia. D. Warm, flushed skin: This finding may indicate fever or vasodilation, but it is not immediately life-threatening in the context of cardiovascular risk. It should be noted, but it does not necessitate immediate intervention compared with left jaw discomfort.
