Dysrhythmias Chapter 31 Exam with Questions and Verified Solutions 1. Which priority concept does the nurse focus on when a client is diagnosed with a dysrhythmia? A. Clotting B. Fluid and electrolyte balance C. Perfusion D. Acid-base balance ANSWER 1. C Perfusion is the priority concept for the client with dysrhythmias. It occurs when there is adequate arterial blood flow through the peripheral tissues (peripheral perfusion) and blood that is pumped by the heart to oxygenate major body organs (central perfusion). Perfusion is a normal physiologic process of the body; without adequate perfusion, cell death can occur. When a client has a dysrhythmia, often perfusion is inadequate. Clotting and fluid and electrolyte balance are interrelated concepts for dysrhythmias. Acid-base imbalance may be a result of inadequate perfusion. 2.
