The sudden onset of cardiac arrest presents one of the most profound challenges in acute care, demanding immediate, skilled intervention and coordinated team response. Effective management hinges on rapid recognition, prompt initiation of cardiopulmonary resuscitation (CPR), and timely administration of advanced cardiovascular life support (ACLS) protocols. This case study examines the critical care of Mr. Arthur Jenkins, a 68-year-old male admitted with a history of coronary artery disease (CAD) and hypertension, who experienced a sudden cardiac arrest (SCA) on the general medical ward. The central thesis is that a nurse's ability to accurately assess the situation, execute ACLS algorithms swiftly, and maintain clear communication within the healthcare team is directly correlated with improved patient outcomes in SCA events.
Mr. Jenkins was admitted following complaints of increasing shortness of breath and chest tightness over 48 hours. His past medical history was significant for two prior myocardial infarctions (MIs) and a stent placement five years ago. He was currently on aspirin, clopidogrel, metoprolol, and lisinopril. Approximately three hours after a routine vital signs check showing stable readings, a registered nurse (RN) responding to an alarm from Mr. Jenkins' cardiac monitor found him unresponsive, pulseless, and apneic. The RN immediately activated the hospital's rapid response team (RRT), initiated high-quality chest compressions, and directed a nursing assistant to retrieve the crash cart and automated external defibrillator (AED). The initial rhythm identified by the AED was ventricular fibrillation (VF), a shockable rhythm.
Upon arrival of the RRT, which included a physician, another RN, and a respiratory therapist, the team transitioned to a structured ACLS approach. While chest compressions continued uninterrupted, an intravenous (IV) line was established, and epinephrine was administered per protocol. Following the first shock, Mr. Jenkins remained in VF. Compressions were resumed, and amiodarone was administered. The team continued to cycle through CPR, rhythm analysis, shocks, and drug administration according to the current AHA guidelines. Throughout this critical period, the primary RN maintained a clear overview, ensuring all aspects of the protocol were followed, documenting interventions accurately, and communicating the patient's status to the team leader. The importance of precise timing in drug administration and defibrillation became evident as the team worked efficiently.
After several cycles, the rhythm converted to organized electrical activity, and a weak pulse was detected. The team initiated post-resuscitation care, focusing on airway management, breathing, circulation, and neurological assessment. Mr. Jenkins was intubated and mechanically ventilated. His core body temperature was managed using therapeutic hypothermia protocols. A 12-lead electrocardiogram (ECG) revealed ST-segment elevation, confirming an ST-elevation myocardial infarction (STEMI) as the likely cause of his arrest. He was transferred to the cardiac catheterization lab for emergent percutaneous coronary intervention (PCI). Post-procedure, he was admitted to the Intensive Care Unit (ICU) for ongoing monitoring and management.
The immediate aftermath of cardiac arrest requires a multidisciplinary approach. In Mr. Jenkins' case, the prompt recognition by the bedside RN, the rapid deployment of the RRT, and adherence to evidence-based ACLS protocols were crucial. The nurse’s role extended beyond performing compressions and administering medications; it involved continuous patient monitoring, accurate rhythm interpretation assistance, documentation, and advocating for prompt diagnostic and therapeutic interventions. Communication was vital, with the RN providing concise updates on the patient's response to treatments, allowing the physician to make informed decisions. Mr. Jenkins ultimately survived the event, albeit with some cognitive impairment, highlighting both the successes and the significant challenges in managing SCA.
