Pneumonia Flashcards
Typical organisms of pneumonia
S. Pneumoniae
H. Influenzae
Gram neg bacilli (k. Pneumoniae, p. Aeruginosa)
Atypical organisms of pneumonia
Mycoplasma pneumonia
Chlamydia pneumonia
Legionella species
Respiratory viruses: adenovirus, RSV
Significant implications on Atypical Pneumonia causative agents
Cannot be seen on Gram stain/standard media culture
RESISTANT TO BETA LACTAM AGENTS!!!!!
***susceptible to MACROLIDES, FLUOROQUINOLONES, TETRACYCLINE
At what age is a person susceptible to CAP in general?
70 years old and above
Dec cough and gag reflexes, reduced antibody & toll-like receptor responses
Classic triad of pneumonia?
This triad presents with
Fever, Cough, Dyspnea
Shortness of breath, tachypnea, tachycardia, hypoxemia with at least 1 chest abnormal finding: Diminished breath sounds Rhonchi Crackles Wheeze
Gross hemoptysis is suggestive of_____?
CA-MRSA
T/F CAP can present with Pleuritic chest pain
T. If the pleura is involved
Pleuritic chest pain is chest pain that worsens with inspirationr
Request for what Xray views of the chest while the patient ________
Request for PA and lateral views of the chest in full inspiration
What can be seen on Chest Xray on CAP?
Diffuse, interstitial infiltrate
Lobar consolidation
Suggestive of severe disease and poor prognosis:
When is microbiologic studies recommended?
Moderate/High risk CAP because additional pathogens like enteric gram negs, P. Aeruginosa, S. Auerus, L. Pneumophila may be causing worsening of sypmtoms
*2 sites of blood culture
*Sputum gram stain and culture
(Bronchoscopic aspirate, bronchoalveolar lavage fluid or brush catheter specimen)
Rationale why request: ABG CBC BUN Crea Liver function test Electrolytes Urinalysis
ABG - to identify and monitor acid-base disturbances of patients in respiratory distress/failure ; O2 supplementation
BUN - help in classification of the patient according to CURB 65
Creatinine - determine GFR and evaluate need for renal dose adjustment especially mag administer antibiotics
AST, ALT - help in deciding drug dosing; decrease clearance of drugs among those with liver failure
ELECTROLYTES - establish baseline results; detect presence of electrolyte imbalances for immediate correction brought about by the infection
URINALYSIS - help assess dehydration status of the patient
