Question 1
A 55-year-old patient with chronic obstructive pulmonary disease arrives for a follow-up. The patient exhibits labored breathing and nasal flaring after walking from the waiting room to the scale.
▸ Why A is the answer
Dyspnea is defined as difficult, labored, or painful breathing, which is clearly demonstrated by the patient's nasal flaring and exertion-induced distress. Apnea is the complete absence of breathing. Eupnea is normal, unlabored breathing. Orthopnea specifically requires the patient to be lying flat to trigger symptoms, whereas this patient is experiencing distress from physical exertion.
🔑 Key takeaway
Dyspnea is the clinical term for difficult, labored, or painful breathing.
