NUR 354 Exam 3 2026 | 100+ Practice Questions & Verified Answers | Acid-Base Balance, ABG Interpretation, Respiratory & Metabolic Disorders

Prepare for NUR 354 Exam 3 with this comprehensive study guide featuring 100+ expertly verified practice questions and detailed answers covering the essential concepts of acid-base balance, arterial blood gas (ABG) interpretation, fluid and electrolyte regulation, and respiratory and metabolic acid-base disorders. This resource provides a structured review of hydrogen ion concentration (pH), buffer systems, respiratory and renal compensation mechanisms, carbonic acid and bicarbonate regulation, normal ABG values, oxygenation assessment, and the physiological processes that maintain acid-base homeostasis. The question-and-answer format reinforces active recall, strengthens critical thinking, and prepares nursing students for classroom examinations, ATI, HESI, and NCLEX-style assessments. This study guide also provides an in-depth review of respiratory acidosis, respiratory alkalosis, metabolic acidosis, metabolic alkalosis, ABG analysis, compensated versus uncompensated acid-base disorders, hypoventilation, hyperventilation, carbon dioxide retention, bicarbonate imbalance, oxygen saturation (SaO₂), partial pressure of oxygen (PaO₂), partial pressure of carbon dioxide (PaCO₂), and nursing interventions for acid-base disturbances. Students will develop confidence in interpreting laboratory findings, recognizing compensation patterns, understanding respiratory and renal regulation, and applying evidence-based nursing interventions in clinical practice. This complete review resource is ideal for nursing examinations, medical-surgical nursing courses, critical care preparation, pharmacology integration, and NCLEX-RN success.
