BSN 445 Week 4 Sherpath 2026/2027 – 80+ Questions & Answers | ECG, Hemodynamics, Cardiac Assessment, Dysrhythmias & Diagnostics

This BSN 445 Week 4 Sherpath 2026/2027 exam preparation resource contains 80+ questions with correct answers across 42 pages, providing an extensive review of cardiovascular assessment, hemodynamic monitoring, electrocardiography, cardiac dysrhythmias, cardiovascular laboratory values, cardiac catheterization, and diagnostic imaging. The opening questions emphasize assessment of patients experiencing acute chest pain, including medication history, chronology and characteristics of pain, 12-lead ECG interpretation, ST-segment changes associated with myocardial injury or ischemia, central cyanosis, clubbing, jugular venous distention, point of maximal impulse, and cardiovascular manifestations of right-sided heart failure, pericarditis, and peripheral arterial disease. The cardiovascular physical-assessment section develops students’ ability to interpret arterial pulses, peripheral perfusion, edema, blood pressure, vascular sounds, and heart sounds. Questions cover posterior tibial and dorsalis pedis pulses, pulse grading, the Allen test, capillary refill, dependent edema, Korotkoff sounds, vascular bruits, S1 and S2 splitting, S4, innocent murmurs, papillary muscle rupture after myocardial infarction, and pericardial friction rubs. Students also review anatomical landmarks such as the right jugular vein, left midclavicular line, intercostal spaces, and the phlebostatic axis. A major portion is devoted to invasive and noninvasive hemodynamic monitoring. The resource covers intra-arterial blood pressure monitoring, transducer leveling and zeroing principles, mean arterial pressure (MAP), waveform damping, central venous pressure, pulmonary artery catheters, thermodilution, cardiac output, contractility, stroke volume, ejection fraction, pulmonary artery diastolic pressure, mixed venous oxygen saturation (SvO2), central venous oxygen saturation (ScvO2), ClearSight monitoring, arterial pulse analysis, and transpulmonary thermodilution. Clinical scenarios require students to recognize how incorrect transducer positioning alters readings and to identify appropriate monitoring technologies for septic shock, ARDS, postoperative coronary artery bypass graft patients, and other critically ill populations. The document also gives substantial attention to central venous and pulmonary artery catheter safety. Students review prevention of central line-associated bloodstream infections through hand hygiene, sterile insertion practices, chlorhexidine skin preparation, chlorhexidine-impregnated dressings, and appropriate dressing changes. Other questions address air embolism indicators such as a mill-wheel murmur, spontaneous migration of a pulmonary artery catheter into the wedge position, calibration of venous oxygen-saturation monitoring, and obtaining hemodynamic measurements at end-expiration. The ECG and dysrhythmia section is particularly detailed. Students review correct 12-lead electrode placement, ECG artifact, P waves, PR intervals, QRS complexes, ST segments, T waves, QT intervals, cardiac axis deviation, ventricular hypertrophy, R-on-T phenomenon, myocardial ischemia, and continuous ST-segment monitoring. Rhythm interpretation includes sinus tachycardia, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia, premature ventricular contractions, ventricular tachycardia, and atrioventricular blocks. Emergency management scenarios address synchronized cardioversion for unstable SVT, anticoagulation considerations before cardioversion of prolonged atrial flutter, defibrillation for pulseless ventricular tachycardia, and temporary pacing for clinically significant AV block. Laboratory interpretation connects cardiovascular assessment with electrolytes, coagulation, heart failure, and atherosclerotic risk. Questions associate hyperkalemia with tall peaked T waves and conduction changes, hypocalcemia with QT prolongation, elevated NT-proBNP with acute heart failure, thrombocytopenia with bleeding risk, INR with warfarin monitoring, and lipid abnormalities with cardiovascular risk. These scenarios help students connect laboratory abnormalities to ECG findings and clinical cardiovascular deterioration. The final portion covers cardiac catheterization and cardiovascular diagnostic testing. Topics include management of hypotension during catheterization, post-femoral-access care, electrophysiology studies, chest radiography, pulmonary edema, treadmill stress testing, transesophageal and two-dimensional echocardiography, MRI contraindications, coronary computed tomography angiography, renal risks associated with contrast studies, and myocardial perfusion imaging. Together, these sections make the resource a broad review of cardiovascular assessment from bedside examination through advanced critical-care monitoring and diagnostic testing. For authoritative academic reinforcement, these concepts correspond closely with AACN critical-care nursing literature and standard references such as AACN Essentials of Critical Care Nursing and Lewis’s Medical-Surgical Nursing: Assessment and Management of Clinical Problems. Dysrhythmia recognition and emergency cardiovascular interventions should additionally be compared with current American Heart Association (AHA) ACLS guidelines, while central-line infection-prevention practices can be verified against current CDC recommendations. Because thresholds and clinical protocols can change, students should use current evidence-based guidelines and institutional policies when a practice-question answer conflicts with contemporary clinical standards. Relevant Students: This document is particularly relevant for BSN 445 students, Sherpath nursing students, BSN and RN students studying critical care, cardiovascular nursing students, adult health and medical-surgical nursing students, ICU and telemetry nursing learners, and students preparing for examinations involving cardiovascular assessment and monitoring. It can also support students reviewing ACLS concepts, ECG interpretation, dysrhythmias, invasive hemodynamics, pulmonary artery catheters, cardiac laboratory values, cardiac catheterization, and cardiovascular diagnostic procedures.
