A 58-year-old client is brought to the emergency department by EMS. Review the triage note. Highlight the findings that require immediate follow-up. A 58-year-old client arrives by EMS at 0842. He reports substernal pressure unchanged for 45 minutes despite resting since onset, with discomfort that spreads down the left arm and new breathlessness while sitting still. EMS gave chewable aspirin 324 mg before arrival. History includes hypertension, hyperlipidemia, and a 30-pack-year smoking history; he takes lisinopril and atorvastatin daily, and his father had a myocardial infarction at 62. A clinic note from last month lists BP 150/92, a resting HR of 68, and SpO2 93 percent on room air. Current findings: BP 152/94 in the right arm, HR 102 and regular, RR 20, T 37.0 C, and SpO2 93 percent, same as his clinic value with unlabored breathing. Lung sounds are clear, and there is trace ankle edema, unchanged from last month. He has pale, cool skin with diaphoresis and is anxious and asks if this is a heart attack. ## Explanation Rest pressure persisting 45 minutes, arm radiation, new dyspnea at rest, pallor with diaphoresis, and a heart rate of 102 against a documented resting rate of 68 form the current ischemic pattern that requires a 12-lead ECG within 10 minutes. The main trap is BP 152/94: it looks alarming, but it is essentially unchanged from his documented 150/92 baseline of poorly controlled hypertension. SpO2 93 percent matches his documented clinic value, is at least 90 percent without distress, and does not call for routine oxygen; trace ankle edema is unchanged from last month; and aspirin, family history, and smoking are context or completed care. ## In-depth explanation Quick answer Highlight the persistent rest pressure, left-arm spread, new breathlessness at rest, HR 102, and pale, cool, diaphoretic skin. Why this is correct Chest pressure that has not eased after 45 minutes of rest, with radiation, dyspnea, and autonomic signs, is a current ischemic pattern that starts the 10-minute ECG clock. HR 102 matters because this client's documented resting rate is 68; the rise is new and consistent with sympathetic activation or reduced stroke volume. Each of these can change within minutes and drives the reperfusion pathway. Easy analogy or mental picture Think of a smoke alarm versus the house's old wiring. The wiring (smoking, hyperlipidemia, family history) explains why a fire could start; the alarm sounding now (pressure, sweating, new tachycardia) tells you a fire is burning. Memory hook Compare before you worry: 150/92 to 152/94 and SpO2 93 to 93 are his normal; HR 68 to 102 is news. NCLEX decision rule When a vital sign is abnormal, check the documented baseline before treating it as a new cue. Current symptoms and new changes from baseline outrank chronic risk factors and completed interventions. Why the other choices are wrong BP 152/94 tempts because it is above normal, but the clinic baseline of 150/92 shows chronic poorly controlled hypertension, not a new change. SpO2 93 percent is the same value documented at his clinic visit, breathing is unlabored, and lungs are clear; it is monitored, and current ACS guidance does not start routine oxygen at 90 percent or above without distress. Trace ankle edema tempts as a heart-failure sign, but it is unchanged from last month and lungs are clear. Anxiety about a heart attack is an expected emotional response. Aspirin 324 mg is completed care to confirm, not a new cue. Smoking and a father with MI at 62 raise pretest probability but do not signal what is happening now.

His clinic record from last month provides blood-pressure, heart-rate, and oxygen-saturation baselines. Clinical judgment target Separate the current ischemic symptom cluster and the new change from baseline from findings that are chronic, expected, or already treated. ## Key concepts - **Acute coronary syndrome** — A spectrum of acute myocardial ischemia that includes unstable angina, NSTEMI, and STEMI. - **Door-to-ECG time** — The interval from arrival to a 12-lead ECG, which should be 10 minutes or less for ongoing ischemic symptoms. - **Baseline vital signs** — Documented usual values that let the nurse judge whether a current reading is a new change or a chronic finding. ## Related questions - [A nurse on a medical-surgical unit reviews the morning labs for a 67-year-old male client …](https://mymerci.kr/pages/nclex_q.php?qn_id=361711&lang=en) - [A 6-year-old client is on the pediatric surgical unit on postoperative day 1 following ton…](https://mymerci.kr/pages/nclex_q.php?qn_id=361812&lang=en) - [A 45-year-old female client with severe iron-deficiency anemia is receiving the first unit…](https://mymerci.kr/pages/nclex_q.php?qn_id=361898&lang=en) - [A 72-year-old male client is receiving a continuous IV heparin infusion for a left lower-e…](https://mymerci.kr/pages/nclex_q.php?qn_id=362064&lang=en) - [A nurse is monitoring an adult client 4 hours after an open abdominal hysterectomy.
