Which term describes difficult or labored respiration?

• A. Dyspnea
• B. Eupnea
• C. Exhalation
• D. Febrile

Answer: (A)

Difficult or labored respiration is described by the term dyspnea. This word captures the subjective sensation of breathlessness or the feeling that breathing is hard work. It’s a useful clinical label because it points to an underlying issue that is making breathing require more effort or be less effective, such as airway obstruction, lung infection, fluid around the lungs, heart problems, or reduced oxygen delivery to tissues. In contrast, eupnea refers to normal, unlabored breathing, so it’s the opposite of what the question describes. Exhalation is simply the act of breathing out and is a phase of the respiratory cycle rather than a descriptor of how difficult breathing is. Febrile relates to fever and describes a body's temperature response, not the effort involved in breathing.
