What does the mMRC dyspnea scale assess?

  1. Cough intensity

  2. Sputum production

  3. Breathlessness

  4. Chest tightness

The correct answer is: Breathlessness

The mMRC (modified Medical Research Council) dyspnea scale assesses the degree of breathlessness or shortness of breath experienced by a patient. This tool is commonly used in assessing the severity of dyspnea in patients with respiratory conditions such as chronic obstructive pulmonary disease (COPD) or asthma. The scale ranges from 0 to 4, with higher scores indicating more severe breathlessness. Choices A, B, and D are incorrect as they do not represent what the mMRC dyspnea scale specifically assesses.
