This nursing case study delves into the diagnosis and management of Acute Coronary Syndrome (ACS) through the fictional case of Betsy. It begins by justifying the use of ECG despite the absence of typical chest pain symptoms, highlighting the importance of recognizing atypical presentations like shortness of breath and nausea. The study thoroughly explains the pathophysiology of various types of angina (stable, unstable, STEMI, and NSTEMI), emphasizing the role of blocked arteries and reduced oxygen supply. An analysis of Betsy's ECG results suggests a possible inferolateral NSTEMI, prompting further cardiac analysis. The report discusses key findings indicative of ACS, such as ST-segment elevation and T-wave inversion, and explores the mechanisms of action, side effects, and nursing considerations for drugs like GTN, diltiazem, and pravastatin. Furthermore, it elucidates the combined use of aspirin and ticagrelor in cardiac patients and addresses the controversial use of morphine in ACS, considering its potential to delay antiplatelet drug administration. The assignment concludes with a comprehensive understanding of ACS management and related pharmacological interventions.
