ACID-BASE BALANCE PROBLEMSFor Nursing 304

Directions: Analyze each component of each set of arterial blood gas (ABG) results, and determine if the findings indicate balance or imbalance. If an imbalance exists, determine if it is acidotic or alkalotic in nature. Then determine if the imbalance represents a respiratory problem or a metabolic problem. Once you have decided what the ABG values indicate, and if an imbalance exists, write at least one cause that could be the underlying reason for the imbalance (don’t use the same reason repeatedly).
