Deck 4 Flashcards
pH of exudative effusion
pH < 7.3- 7.45
Pleural fluid analysis in PE:
unilateral, bloody with normal glucose values and negative cytology
Ligation of which artery is recommended for refractory epistaxis
Sphenopalatine artery
Management for post-drowning with SpO2 of 90% despite using O2
Endotracheal intubation
signs of SVC syndrome
- headache that worsens when leaning forward
- engorged veins over chest
- swelling of head, neck and upper extremities
Management of penetrating trauma **hemo. unstable **
exploratory laparotomy
Features of foreign body aspiration
- **unilateral wheezing **
- acute cough
- sob
Managements of open pneumothorax (will have bubbling of blood)
- temporary: partially occlusive dressings
- permanent: chest tube
What to do if suspected asthma in pt is not improving with inhaler?
try a trial of PPI since cough can be caused by GERD
Tx for CAP with no comorbidities and no risk factors for drug-resitant bugs
- amoxicillin
- doxycycline
- macrolide (azithro)
next step in management of suspected **acute tonsilitis **
confirm before tx –> obtain throat culture
When to perform tracheostomy
- long term mechanical ventilation
- upper airway obstruction (mass in neck)
CURB-65
- C- confusion
- U- uremia (> 7)
- R- resp rate > 30
- B- BP of < 90 / < 60
- 65- > 65y/o
tx for CAP with >2 in curb-65
macrolide + cefotaxime
Marker of granulomatosis w. polyangitis
c-ANCA titers
what systems are involved in granulomatosis w. polyangiitis (GPA)
- vasculitis (palpable purpura)
- respiratory infections (sinusitis, nasal ulcers, hemoptysis)
- glomerulonephritis (RBC casts)
Tx of CAP in pregnancy
inpatient tx with azithromycin + ampicillin-sulbactam
How to know if viral sinusitis became a bacterial superinfection
watery nasal discharge becomes mucopurulent (yellowish) over the course of days
Tx of bacterial rhinosinusitis
amoxi-clav
what would happen if pt with left-sided pneumonia is turned to the left
increased perfusion of nonventilated alveoli –> increased A-a gradient
How is the A-a gradient in asbestosis?
Increased
Silicosis increases the risk of what infection?
M. tuberculosis (primary TB)
Galactomannan antigen is suggestive of:
Aspergillosis
MC bug for postviral bacterial pneumonia
Strep. pneumo
