Pulmonary Flashcards
How is a cough classified?
Length of time it has occurred
Acute: Less than 3 weeks
Sub-Acute: 3-8 weeks
Chronic: Over 8 weeks
What are the four common etiologies for an acute cough lasting less than 3 weeks?
Acute respiratory infection (bronchitis), exacerbation of COPD/asthma, pneumonia, pulmonary embolism
What are the 7 common etiologies for a sub-acute to chronic cough?
GERD, asthma, infection (atypical pneumonia, pertussis), Ace Inhibitors (dry cough after 1-3 weeks), chronic bronchitis (smokers), bronchiectasis (chronic cough, viscid sputum, bronchial wall thickening on CT), and lung CA (less than 2%)
A 34-year-old non-smoker Who is otherwise healthy has been diagnosed with acute bronchitis. His symptoms have persisted for the past four days. What’s an appropriate treatment for him?
Likely viral. Treat symptomatically.
What are the three most common bugs in community acquired pneumonia?
Strep pneumo - 14% - rust colored sputum; most common cause of death from Pneumonia
Mycoplasma pneumoniae - 16% - most common
Chlamydophila pneimoniae - 12%
What characteristics should make the nurse practitioner suspect that a pneumonia is secondary to DRSP?
Recent antibiotic exposure
In what cases would you suspect DRSP?
Older, sicker patients with recent antibiotic exposure
1) Age over 65
2) Beta-lactam, Macrolide, or respiratory quinolone therapy in the three months prior
3) alcoholism
4) medical comorbidities
5) immunosuppressive illness or therapy
6) exposure to a child in daycare
What patient is most likely to harbor an atypical pathogen?
1) 19 year old type 1 diabetic
2) A 27-year-old with asthma; recent sinus infection treated with Augmentin
3) A 39-year-old smoker of one pack per day
4) A 48-year-old who has teenagers in the household
A 48-year-old who has teenagers in the household.
The other three options are indicative of DRSP
What are the usual clinical signs and symptoms in a patient who has pneumonia?
Cough 90%, purulent sputum production, fever - more than 80%, chills 40-50%, shortness of breath - over 24 BPM, pleuritic chest pain - over 30%, increased respiration and heart rate (older patients), leukocytosis 15-30000/mm
Guidelines for treatment of pneumonia. What is the first choice for an individual who is healthy with no anabiotic exposure in the last 3 months?
Macrolide x 5 days (azithromycin or clarithromycin) or doxycycline BID daily
Discourage quinolone use initially!
If DRSP is suspected, what is the treatment guidelines for pneumonia?
Respiratory quinolone x 5 days
(-floxacin)
Or beta-lactam (PCN or cephalosporin) PLUS macrolide
Or beta-lactam plus doxycycline
What is the criteria for hospital admission for patients with pneumonia?
CRB 65 C= confusion R= respiratory rate above 30 B= BP under 90 systolic or under 60 diastolic 65 = age over 65
Who should get the pneumococcal vaccine? (PPSV23)
Adults 19 to 64 who are at increased risk of pneumococcal disease (Individuals with chronic diseases)
Who should get the PCV 13 (Prevnar) Plus the PPSV23 (after 1 year)
All adults over 65 years old
Those aged 19 to 64 with asplenia, immunocompromise conditions, CSF leaks, cochlear implant’s, advanced CKD, steroid use
* Not recommended for healthy adults under 65
What is the definition of COPD?
A common preventable and treatable disease; persistent airflow limitation, usually progressive, enhanced chronic inflammatory response of the airways and lung to noxious particles or gases
Exacerbations and comorbidities contribute to severity
4th leading cause of death
What are the risk factors for COPD?
Cigarette smoke, occupational dust and chemicals, environmental tobacco smoke, indoor and outdoor air pollution, genes, infections, socioeconomic status, aging populations
What are the symptoms of COPD?
Chronic and progressive dyspnea, cough, and sputum production that varies from day to day
The dyspnea is progressive, persistent, and worsens with exercise.
The cough may be intermittent and unproductive
The chronic sputum production is common
What are the differential diagnoses for COPD?
COPD - midlife on that, slow progression of symptoms; history of exposure to lung irritants
Heart failure - dilated heart, pulmonary Edema, no airflow limitation
asthma - early in life on that usually, wide variation in symptoms from day today, symptoms may worsen in early a.m. or evening nighttime, history of allergic rhinitis/eczema/family history
tuberculosis - any age; infiltrate on chest x-ray. Sputum confirmation
How do you diagnose COPD?
Symptoms: shortness of breath, chronic cough, sputum
Exposure to risk factors: Tobacco, occupation, indoor /outdoor pollution
**Spirometry is required to establish diagnoses
What confirms a diagnoses of COPD?
Spirometry: Post bronchodilator shows FEV1/FVC ratio less than .70
What is an FVC?
Forced vital capacity = Max volume of air exhaled during a forceful maneuver
