Acid-Fast Bacillus (AFB) Staining (Ziehl-Neelsen) correct answer: Used for the diagnosis of tuberculosis, tuberculous infections and leprosy. Organisms will appear red against a blue background when stained by this method. Usually takes 2-3 weeks to culture the tubercle bacilli. Results of the AFB stain may indicate the need for the initiation of therapy. Airway Resistance (Raw) correct answer: Estimated for patients on mechanical ventilation by determining the difference between peak airwa...
