Acute Coronary Syndrome V: Nursing Management

The primary nursing diagnoses for ACS are acute chest pain related to reduced blood flow to the heart and ineffective breathing patterns related to pulmonary edema. These diagnoses are based on patient reports of severe, crushing chest pain that may radiate to the left arm and evidence of shortness of breath or labored breathing. Formulating accurate diagnoses guides targeted interventions to relieve pain, prevent myocardial damage, and maintain effective respiratory function.

Nurses should position ACS patients in a semi-Fowler's position at a 45-degree angle to improve chest expansion and facilitate breathing. Allowing patients to lean forward if tolerated further enhances comfort and ventilation. This positioning reduces the work of breathing and helps manage symptoms related to pulmonary edema or congestion.

Essential objective assessments include continuously monitoring vital signs such as heart rate, blood pressure, respiratory rate, and oxygen saturation to detect hemodynamic instability. Nurses perform cardiovascular examinations noting abnormal heart sounds, conduct respiratory assessments for pulmonary congestion, check peripheral vascular perfusion, analyze 12-lead ECG readings, and measure cardiac biomarkers like troponins and CK-MB to confirm myocardial injury.

Nitroglycerin is administered to relieve chest pain and improve blood flow to the heart. Aspirin is given as ordered to reduce platelet aggregation and prevent clot formation. Morphine may be prescribed for pain management while closely monitoring for hypotension and respiratory depression. All medications require careful vital sign monitoring and documentation of patient response.

Nurses administer supplemental oxygen if oxygen saturation falls below 90 percent, maintaining a target saturation range of 90 to 94 percent. Oxygen therapy improves myocardial oxygenation and reduces ischemic injury. Nurses continuously monitor oxygen saturation levels and adjust oxygen delivery based on patient response and clinical status.

Nurses teach diaphragmatic breathing and pursed-lip breathing techniques to improve ventilation and reduce dyspnea. Encouraging frequent deep breathing and coughing exercises helps prevent pulmonary complications and promotes gas exchange. These techniques empower patients to actively participate in their recovery and manage breathing difficulties.

Nurses regularly assess patient outcomes including pain levels, respiratory function, and hemodynamic stability to evaluate care effectiveness. Based on these assessments, the care plan is modified to address changing patient needs and ensure optimal recovery. Continuous evaluation and adjustment of interventions demonstrate responsiveness to patient progress and promote evidence-based nursing practice.
