A nursing student comes into your office because they are struggling with the concept of pulmonary function. They know you as an experienced FNP and so they are comfortable asking if you could clarify the terms residual volume (RV), functional reserve capacity (FRC), total lung capacity (TLC) inspiratory reserve volume (IRV), and expiratory reserve volume (ERV).
Give her a definition of each?
List three (3) disorders that can alter the residual volume and explain how they do so?
This is a question for advanced pathophysiology.
