When completing a focused respiratory assessment, which intervention should the practical nurse (PN) implement to assess for hemoptysis?

A. Observe the appearance of sputum: Hemoptysis is coughing up blood. The primary method of identifying it is by directly observing sputum color and content. B. Watch chest expansion on inspiration: Assesses ventilation and symmetry, but not presence of blood in sputum. C. Determine how often the cough occurs: Evaluates frequency but not the nature of sputum production. D. Auscultate bilateral breath sounds: Assesses air movement and adventitious sounds, but not the presence of blood.
