question 4 of 20
a middle - aged client presents to the ed reporting severe chest discomfort. which finding is most indicative of a possible myocardial infarction (mi)?

• cool, clammy skin and a diaphoretic, pale appearance
• chest discomfort not relieved by rest or nitroglycerin
• intermittent nausea and emesis for 3 days
• anxiousness, restlessness, and lightheadedness

Explanation:

To determine the most indicative finding of a myocardial infarction (MI), we analyze each option:

• Option 1: Cool, clammy skin, diaphoresis, and pale appearance are common in shock or severe distress but not specific to MI.
• Option 2: Chest discomfort not relieved by rest or nitroglycerin is a key diagnostic criterion for MI, as angina (chest pain from ischemia) typically improves with rest/nitroglycerin, while MI pain persists.
• Option 3: Intermittent nausea/vomiting for 3 days is not specific to MI (could be GI issues) and lacks the acute onset typical of MI.
• Option 4: Anxiety, restlessness, and lightheadedness are non - specific symptoms that can occur in various conditions, not unique to MI.

Answer:

B. Chest discomfort not relieved by rest or nitroglycerin
