Critical Care NUR 283 Test 2 2026/2027 | 150+ Questions & Answers | Dysrhythmias, Hemodynamics, Cardiac & Neurologic Emergencies

This comprehensive Critical Care NUR 283 Test 2 2026/2027 study guide contains 150+ exam-style questions and answers across 41 pages covering high-yield cardiovascular and neurologic concepts encountered in critical care nursing. The cardiovascular section begins with ECG rhythm recognition and life-threatening dysrhythmias, including unifocal and multifocal PVCs, monomorphic ventricular tachycardia, ventricular fibrillation, torsades de pointes and asystole. It reviews CPR, defibrillation, synchronized cardioversion, epinephrine, amiodarone, magnesium replacement and assessment of contributing factors such as hypoxia, ischemia and electrolyte disturbances. The document provides extensive preparation on pacemakers, implantable cardioverter-defibrillators and emergency cardiac interventions. Students review transcutaneous, transvenous and epicardial pacing; atrial, ventricular and atrioventricular pacing; pacemaker failure to capture; undersensing and oversensing; device interrogation; post-pacemaker nursing care; and complications such as bleeding, infection, lead displacement and cardiac tamponade. It also distinguishes unsynchronized defibrillation for ventricular fibrillation and pulseless ventricular tachycardia from synchronized cardioversion for selected unstable tachyarrhythmias with a pulse. Another major focus is hemodynamic monitoring and heart failure. The questions cover cardiac output, mean arterial pressure, central venous pressure, arterial-line monitoring, preload, afterload, contractility, passive leg raising, fluid therapy, vasopressors, inotropes, ejection fraction, systolic versus diastolic heart failure, BNP, digoxin and signs of inadequate organ perfusion. Students are required to connect abnormal hemodynamic findings with appropriate nursing assessment and intervention, making this section especially useful for ICU and acute-care examination preparation. The cardiovascular disease material extends to pericarditis, pericardial effusion, cardiac tamponade, endocarditis, myocarditis and valvular disorders. Important concepts include Beck's triad, pericardiocentesis, echocardiography, blood cultures, vegetations, Osler nodes, Janeway lesions, murmurs, mitral regurgitation, mitral stenosis, aortic regurgitation and aortic stenosis. The guide also reviews thoracic and abdominal aortic aneurysms, superior vena cava syndrome, blood-pressure management, endovascular aneurysm repair and postoperative monitoring. The latter portion transitions into neurologic critical care, including Glasgow Coma Scale assessment, cranial nerves IX and X, phenytoin administration and monitoring, decorticate versus decerebrate posturing, and brainstem assessment using the oculocephalic and oculovestibular reflexes. Together, these topics make the document a broad Test 2 review resource for recognizing deterioration, prioritizing interventions and applying critical-care nursing principles to cardiovascular and neurologic emergencies. For academic context, the material corresponds broadly with concepts taught in established critical-care references such as Urden, Stacy & Lough's Critical Care Nursing: Diagnosis and Management and AACN's Essentials of Critical Care Nursing. Emergency rhythm-management topics should additionally be studied alongside current American Heart Association ACLS guidelines, particularly because resuscitation algorithms, medication recommendations and clinical practice standards can change. The uploaded document identifies the course as NUR 283 Critical Care but does not identify a university, so an institution has not been invented for SEO purposes. Relevant Students: This document is relevant to NUR 283 students, Critical Care Nursing students, registered nursing students, BSN and ADN students, ICU nursing students, advanced medical-surgical nursing students, nursing students preparing for cardiovascular or neurologic exams, ACLS learners, and students reviewing ECG interpretation, dysrhythmias, hemodynamics, heart failure, cardiac emergencies, pacemakers, aneurysms and neurologic assessment.
