Flashcards in Chapter 15: Respiratory Infections 1 Deck (15):
What structures are affected by URIs?
Nasal passages, throat, epiglottis, and sinuses
What structures are affected by lower respiratory infections?
Bronchial tubes and lungs
A lower respiratory infection in which the alveoli become filled with fluid.
What is the most important means by which pneumonia is classified?
Etiology (bacterial, viral, fungal, etc)
In what ways is PNA classified?
2) Anatomic distribution
3) Predisposing factors
What type of PNA is characterized by infection of an entire lung lobe with pathogenic bacteria (neutrophil infiltration)
Type of PNA in which parts of lobes adjacent to bacterial infected bronchi become infiltrated with neutrophils
Type of PNA caused by virus or Mycoplasma in which the alveolar septa (rather than the alveoli) are infiltrated by lymphocytes, monocytes, and plasma cells.
Interstitial or Primary Atypical PNA
True or false: Mycoplasma, Chlamydia, and Rickettsia can cause PNA
What is the most common type of bacteria that causes PNA?
What can predispose someone to PNA?
Any condition associated with poor lung ventilation and retention of bronchial secretions
Type of PNA caused by foreign body, food, vomit, etc. being aspirated into lungs.
What type of treatment will not work against mycoplasma bacterial infection?
Penicillins; mycoplasma don't have cell walls, so abxs like penicillins that inhibit cell wall formation will not be effective.
What are the sxs of PNA?
1) Like other systemic infections (fever, feel ill, increased WBCs)
2) Sxs of lung inflammation (cough, SOB, pain on respiration if pleura affected, low O2 sat, purulent sputum)
