A nurse is admitting a client who reports tightness in their chest that radiates to left arm.Click to highlight the findings below that would indicate that the client has a potential problem. To deselect a finding, click on the finding again. Nurses' Notes: 1000: Client reports tightness in chest that radiates to left arm. States pain as 7 on a scale of 0 to 10. Started to feel nauseous after breakfast. Client states, "I had scrambled eggs and bacon like I do every morning." Client is diaphoretic and short of breath. Heart rate is irregular and tachycardic. Alert and oriented to person, place, and time. Lungs clear to auscultation in all lobes. Bowel sounds are present in all 4 quadrants. +1 pedal pulses. Skin is cool to touch. Capillary refill less than 2 seconds.

This case focuses on identifying assessment findings consistent with an acute myocardial infarction (MI), specifically ST-elevation myocardial infarction (STEMI). The client has classic cardiac ischemia symptoms including chest pain radiating to the left arm, diaphoresis, nausea, and dyspnea, along with elevated cardiac biomarkers and ECG evidence of ST-segment elevation. Prompt recognition of these findings is critical because myocardial tissue damage progresses rapidly without intervention. Nursing priorities include identifying signs of poor perfusion, decreased cardiac output, and ongoing ischemia. Rationale for correct findings: • Tightness in chest that radiates to left arm: Chest pain radiating to the left arm is a classic manifestation of myocardial ischemia and acute coronary syndrome. It occurs when reduced coronary blood flow causes myocardial oxygen deprivation and tissue injury. This symptom strongly suggests cardiac origin rather than gastrointestinal discomfort. It is a priority finding requiring immediate intervention. • Pain rated 7/10: Severe chest pain indicates significant myocardial oxygen demand and ongoing ischemia. Persistent pain suggests inadequate coronary perfusion and may indicate active infarction. Pain severity helps guide urgency of treatment and response to therapy such as nitroglycerin or morphine. This is a major indicator of cardiac compromise. • Diaphoresis: Diaphoresis is caused by sympathetic nervous system activation during acute myocardial ischemia. It reflects significant physiologic stress and is commonly associated with acute coronary events. Cold sweating with chest pain is highly concerning for MI. This finding supports the urgency of intervention. • Shortness of breath: Dyspnea indicates reduced cardiac output and impaired oxygen delivery to tissues. It may result from myocardial dysfunction, pulmonary congestion, or the body’s response to decreased oxygenation. In MI, shortness of breath is a major warning sign of worsening cardiac function. It requires prompt assessment and management. • Heart rate irregular and tachycardic: Tachycardia and irregular rhythm suggest cardiac electrical instability caused by ischemia. Dysrhythmias are common and potentially life-threatening complications of myocardial infarction. An irregular, rapid heart rate can reduce cardiac output further and worsen tissue perfusion. Continuous monitoring is essential. • +1 pedal pulses: Weak peripheral pulses indicate reduced systemic perfusion and decreased cardiac output. In the setting of acute MI, diminished pulses suggest compromised circulation and poor forward blood flow. This may reflect worsening cardiac pump function. It is an important sign of hemodynamic instability. • Skin cool to touch: Cool skin reflects peripheral vasoconstriction caused by sympathetic compensation during reduced cardiac output. The body redirects blood flow to vital organs such as the heart and brain, leaving the skin cool and clammy. This is a common sign of poor perfusion during acute MI. It indicates worsening circulatory status. Rationale for incorrect findings: • Alert and oriented to person, place, and time: This indicates preserved neurological status and adequate cerebral perfusion at this time. There is no evidence of confusion, decreased level of consciousness, or neurological compromise. While ongoing monitoring is important, this finding does not indicate deterioration. It is considered stable rather than concerning. • Lungs clear to auscultation in all lobes: Clear lung sounds suggest there is no current pulmonary edema or significant fluid overload from heart failure. This is a reassuring finding because acute MI can lead to left ventricular failure and crackles. Since breath sounds are normal, this does not indicate an immediate complication. It is not a priority concern. • Capillary refill less than 2 seconds: Normal capillary refill suggests adequate peripheral perfusion despite other concerning findings. It indicates that distal circulation is still being maintained. Although weak pulses and cool skin are concerning, this specific finding alone is within normal limits. It is not considered a priority problem.
