Answer: B - The dyspnea scale - first created to help patients with cardiopulmonary conditions such as emphysema - is a scale that assesses difficulty in breathing. It is a subjective self-assessment and the scale ranges from +1 (the least difficulty) to +4 (the most difficulty). At a +4 level, class members are having severe difficulty with breathing and should be instructed to decrease their intensity or to rest for a few minutes.
