NPS Diagnostic Testing Exam Questions (120 Q&A) – RESP 202, PFT, ABG, Hemodynamics, Sleep Studies – Kettering

This document contains approximately 120 exam-style questions with fully verified answers focused on diagnostic testing in respiratory care. It provides comprehensive coverage of pulmonary function testing (PFT), including spirometry interpretation (FEV1, FVC), flow-volume loops, peak expiratory flow rate (PEFR), and bronchial provocation testing. As shown on page 1, the material begins with core PFT indications such as diagnosing lung disease, monitoring progression, assessing exercise tolerance, and pre-operative evaluation. The document also explores arterial blood gas (ABG) analysis in depth, including sampling techniques (arterial, capillary, UAC), interpretation of oxygenation and ventilation status, and clinical decision-making for hypoxemia (V/Q mismatch vs shunt vs hypoventilation). It further covers advanced monitoring tools such as capnography (PETCO₂ waveforms), pulse oximetry, co-oximetry, and transcutaneous monitoring, with practical troubleshooting scenarios like air bubbles or sensor misplacement. In addition, the material includes detailed explanations of sleep diagnostics (polysomnography, apnea-hypopnea index), apnea classification (central, obstructive, mixed), and neonatal monitoring such as apnea-bradycardia systems and SIDS risk factors. It also provides an extensive overview of hemodynamic monitoring, including CVP, PAP, PCWP, cardiac output, systemic and pulmonary vascular resistance, and the use of pulmonary artery catheters (Swan-Ganz). These concepts are aligned with core respiratory care textbooks such as Egan’s Fundamentals of Respiratory Care, making the document highly relevant for both academic learning and clinical application. This resource is ideal for students enrolled in RESP 202 (Diagnostic Testing), Cardiopulmonary Diagnostics, Pulmonary Function Testing, and Critical Care Monitoring courses. It is highly beneficial for respiratory therapy students preparing for NBRC (CRT/RRT/NPS exams), as well as nursing students (ICU, pulmonary, sleep lab), paramedic trainees, and healthcare professionals seeking to strengthen diagnostic interpretation and clinical reasoning skills.
