Pulmonary Infectious Diseases Flashcards
What are common respiratory complaints?
1. Cough A. Sputum production 2. Dyspnea 3. Wheezing 4. Difficulty breathing 5. Chest Pain
What are common questions to ask in the HPI in a pulmonary pt?
- Onset of sx’s
- Sputum production
- Hemoptysis
- Shortness of breath
- Wheezing
- Chest pain
A. Radiation of pain - Constitutional sx’s:
A. Elderly may not have fever, look for confusion - Social Hx
- Exposure to illness
- Prior episodes
What should be observed on a physical exam of a pulmonary pt?
- Acute distress
2. Cyanosis: central vs. peripheral
What should be palpated on a physical exam of a pulmonary pt?
- Chest wall tenderness
2. Tactile fremitus
What should be percussed on a physical exam of a pulmonary pt? What are the results?
- Lung fields
Resonant, hyper-resonant, dull - Diaphragmatic excursion
What may be the auscultation results for a pulmonary pt?
Clear, rhonchi, wheezing, rales
What are the dx studies for a pulmonary pt?
- Medical Imaging
A. CXR (PA and lateral, first study done), CT (as needed) - CBC w/ diff: viral vs. bacterial etiology
- Sputum culture: hard to collect, give a nebulizer treatment first to open up bronchi
- Blood culture
- Arterial blood gas (ABG’s)
- Pulmonary function tests (PFT’s)
What is the primary etiology of acute bronchitis?
- Primarily viral
A. Rhinovirus (common cold sxs, most common in fall and winter months)
B. adenovirus:
-conjunctivitis, GI symptoms like diarrhea
C. influenza: chills, fever, muscle/joint aches. May have N/V in children
D. parainfluenza: 4 types, URI and LRI infections, high risk for croup in children. Looks like a mild cold
What are the bacterial etiologies -
A. Mycoplasma pneumonia: “walking pneumonia”, young adults
B. Bordetella pertussis: not very common due to vaccines
C. Chlamydia pneumoniae
D. Streptococcus pneumoniae
E. Hemophilus influenzae: not very common due to vaccines
What other etiologies or concomitant diseases can cause acute bronchitis?
allergic or irritant
Often occurs after or with a URI
What are the primary etiologies of acute bronchitis in COPD pts?
- Hemophilus influenzae
- Strep pneumonia
- Moraxella catarrhalis
What are the symptoms of acute bronchitis?
1. Cough A. Non-prod or productive 2. Dyspnea 3. ST 4. +/- fever 5. Myalgias 6. CP 7. Malaise 8. Irritant exposure 9. GI sx’s w/adenovirus
What are the signs of acute bronchitis?
- Rhonchi
- Wheezing
- No abn auscultatory findings
- Myringitis
- Conjunctivitis
- Adenopathy
What are the dx studies for acute bronchitis?
- Usually none unless attempting to rule out pneumonia
A. CXR
What acute bronchitis etiology can lead to otitis media and croup in children under 2 years old?
Adenovirus
What are the supportive care treatments for healthy adults with acute bronchitis?
- Hydration
- Acetaminophen/Ibuprofen prn fevers, myalgias
- Prednisone
What are the treatments for wheezing in healthy adults with acute bronchitis?
- Beta 2 agonist
A. Albuterol (Proventil/Ventolin/ProAir) for wheezing
B. Levalbuterol tartrate (Xopenex) - Anticholinergic
A. Ipratropium (Atrovent) for wheezing - Antitussives or Expectorants
A. Guaifenesin (Mucinex), dextromethorphan (Robitussin DM), codeine
What are the abx treatments for COPD/asthma pts with acute bronchitis?
- Macrolides
A. Azithromycin (Z-pak), clarithromycin (Biaxin), erythromycin
B. Effective against mycoplasma, chlamydia, pertussis - Doxycycline
A. Effective against chlamydia - Trimethoprim Sulfa (Bactrim)
A. Effective against gram negatives, including Hemophilus
What infectious agent does doxycycline treat?
Chlamydia
What infectious agents do macrolides treat?
mycoplasma, chlamydia, pertussis
What infectious agents does trimethoprim sulfa (bactrim) treat?
gram negatives, including Hemophilus
What should acute bronchitis pts be educated about?
- Droplet precautions
- Hydration
- Hand-washing
- Return if increasing sx’s
What are the etiologies of influenza?
1. Influenza A A. Generally more pathogenic 2. Influenza B A. Generally less pathogenic 3. Influenza C A. Mild illness in humans
