This document contains the complete test bank for Davis Advantage for Pathophysiology, 3rd Edition () by Theresa Capriotti and Joanne Calzone. It includes all chapters (1 through 46) with questions, correct answers, and detailed rationales. This resource is designed to support exam preparation, practice, and in-depth understanding of key pathophysiology concepts. Chapter 1, The Cell in Health and Illness Multiple Choice Identify the choice that best completes the statement or answers the question. 1. Which statement regarding the sodium–potassium pump is correct? 1. The cell’s plasma membrane is more soluble to sodium ions than potassium ions. 2. The concentration of sodium ions should be higher inside the cell compartment. 3. The concentration of potassium ions should be higher outside the cell compartment. 4. The active transport involves pumping out three sodium ions and pumping in two potassium ions. 2. In the absence of oxygen, which cellular function creates the same amount of energy as is created inthe presence of oxygen? 1. Dissipation of pyruvic acid 2. Initiation of the citric acid cycle 3. Activation of acetyl-coenzyme A 4. Creation of acidosis via lactic acid 3. How many adenosine triphosphates (ATPs) are produced in aerobic energy metabolism? 1. 2 2. 3 3. 34 4. 53 4. Which cell organelles differ in their number according to the cell’s energy needs? 1. Ribosomes 2. Mitochondria 3. Ribonucleic acids Chapter 1, The Cell in Health and Illness Answer Section MULTIPLE CHOICE 1. ANS: 4 Chapter: Chapter 1, The Cell in Health and Illness Objective: Recognize the major organelles and their function within the cell. Page: 1 Heading: Cell Structure and FunctionThe Sodium Potassium Pump (Na+/K+ Pump) Integrated Process: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Comprehension [Understanding] Concept: Cellular Regulation Difficulty: Moderate Feedback 1 This is incorrect. The plasma membrane of the cell is less soluble to sodium ions and more soluble to potassium ions. 2 This is incorrect. The concentration of sodium ions should be higher outside the cell compartment. 3 This is incorrect. The concentration of potassium ions should be higher inside the cell compartment. 4 This is correct. In active transport, for every three sodium ions pumped out, two potassium ions are pumped in. PTS: 1 CON: Cellular Regulation 2. ANS: 2 Chapter: Chapter 1, The Cell in Health and Illness Objective: Discuss the difference between aerobic and anaerobic metabolism. Page: 3 Heading: Cell Structure and FunctionEnergy Metabolism Integrated Process: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Analysis [Analyzing] Concept: Cellular Regulation Difficulty: Difficult Feedback 1 This is incorrect. When oxygen is not available, anaerobic metabolism produces significantly less cellular energy: a net yield of 2 ATP, as well as pyruvic acid. 2 This is correct. In the absence of oxygen, pyruvic acid is converted into acetyl- coenzyme A, which triggers a series of reactions known as the Krebs cycle, also called the citric acid cycle. 3 This is incorrect. Pyruvic acid is converted into acetyl-coenzyme A, not activated. 4 This is incorrect. In cellular hypoxia, pyruvic acid is converted to lactic acid, which is noxious to cells, causing muscle pain and biochemical alterations such as acidosis. PTS: 1 CON: Cellular Regulation 3.
