A patient diagnosed with multiple sclerosis has decreased vital lung capacity. The nurse is aware that vital capacity measures:
A) The volume of air inhaled and exhaled with each breath
B) The volume of air in the lungs after a maximum inspiration
C) The maximum volume of air inhaled after normal expiration
D) The maximum volume of air exhaled from the point of maximum inspiration
Ans: D
Feedback: Vital lung capacity is the maximum volume of air exhaled from the point of maximum inspiration; neuromuscular disorders, such as multiple sclerosis, may lead to a decreased vital capacity. Tidal volume is defined as the volume of air inhaled and exhaled with each breath. The volume of air in the lungs after a maximum inspiration is the total lung capacity. Inspiratory capacity is the maximum volume of air inhaled after normal expiration.
