Scott PY - 2019 T2 - McGraw-Hill's NAPLEX® Review Guide, 3e AB - A lower respiratory tract infection (LRTI) is an infection below the level of the larynx and includes bronchitis, bronchiolitis, and pneumonia. LRTIs result from viral or bacterial invasion of lung parenchyma. Viral infections are diagnosed by the recognition of characteristic constellation of clinical signs and symptoms and treatment consists of supportive care measures (except for influenza, antivirals may be given). Bacterial LRTIs (in particular bacterial pneumonia) requires expedient, effective, and specific antimicrobial therapy. An appropriate treatment regimen for the patient with an LRTI can be established with the aid of a thorough medical history, physical examination, chest radiograph, knowledge of common bacterial pathogens, and results of properly collected cultures. This chapter will focus on pneumonia; see the special considerations section for information on bronchitis and bronchiolitis.
