NURS 1871 Exam 1 – 100+ Q&A | Respiratory, Gas Exchange, COPD, Heart Failure, Oxygenation | CSCC 2025

This comprehensive study guide offers 100+ verified questions and answers for NURS 1871 – Exam 1 at Columbus State Community College (CSCC) for the 2025–2026 academic year. Designed for concept-based nursing programs, it provides a focused review on gas exchange, oxygenation, respiratory assessment, cardiac function, perfusion, and patient safety. The document starts with the structure and function of the respiratory system, identifying key anatomy across the upper and lower respiratory tracts. Students will review pathologies such as atelectasis, asthma, COPD, and pneumonia, alongside assessment techniques including auscultation, respiratory pattern identification (e.g., Kussmaul, Cheyne-Stokes), and use of pulse oximetry. It explores the clinical manifestations and management of oxygenation impairment, including early vs. late signs of hypoxia, use of incentive spirometry, and proper administration of oxygen via nasal cannula, simple mask, and non-rebreather. The guide also outlines detailed characteristics and interventions for abnormal lung sounds like wheezes, crackles, rhonchi, stridor, and pleural friction rub. The cardiovascular section covers cardiac output, systole vs. diastole, orthostatic hypotension, heart sounds (S1–S4), murmurs, and landmark auscultation points (A, P, T, M). Students are guided through recognizing left- and right-sided heart failure, including signs like pulmonary edema, JVD, weight gain, fatigue, and crackles. Additional topics include fall prevention, restraint safety, and documentation standards per institutional and national guidelines. All answers are correct and formatted to match NCLEX-RN style thinking. Perfect for: – Students in ADN, BSN, ASN, or entry-level concept-based nursing programs – Courses in Foundations of Nursing, Cardiopulmonary Care, Health & Illness Concepts, or Adult Nursing I – Exam preparation for NCLEX-RN, ATI, HESI, or CSCC's concept-based exams This resource is clinically aligned and exam-focused, making it an essential tool for foundational nursing success.
