How is dyspnea defined?

1. Fast breathing

2. Respiratory arrest

3. Shortness of breath

4. Shallow breathing

The correct answer is: Shortness of breath

Dyspnea is defined as a subjective sensation of discomfort or difficulty in breathing. It is not specifically defined by the speed or depth of breathing, but rather the feeling of not being able to get enough air. Option A is too general and does not accurately reflect the definition of dyspnea. Option B is a severe condition that is characterized by the complete cessation of breathing, whereas dyspnea refers to a difficulty or discomfort in breathing. Option D is also not specific enough and does not capture the true definition of dyspnea. Therefore, option C, shortness of breath, is the most accurate definition of dyspnea.
