1

Bronchiectasis

bronchial thickening and dilation to due to a recurrent cycle of bacterial infection, inflammation and tissue damage

2

In young patient, most common underlying etiology for bronchiectasis is

cystic fibrosis

3

where in the lung is bronchiectasis due to cystic fibrosis located

upper lung lobe

4

common side effect of systemic glucocorticoids seen in labs

leukocytosis with neutrophilic predominance

5

what lab value is expected for hypersensitivity reaction

eosinophilia

6

MOA of ACE

metabolism of kinins and substanceP

7

destruction and permanent damage of the conducting airway occurs in

bronchiectasis

8

pt with COPD and acute-onset shortness of breath, hypoxia and unilaterally decreased breath sounds likely has? most common cause?

secondary spontaneous pneumothorax
- alveolar blebs

9

risk factors for obstructive atelectasis

- foreign body aspiration
- malignancy
- severe pneumonia ( mucus plug)

10

pts develop what after a fat embolsm

- respiratory distress
- neurological abnormalities
- petechial rash

11

acute dyspnea and hypoxia after motor vehicle collision likely has what

pulmonary contusion
- he was prone to blunt thoracic trauma

12

clinical feature of pulmonary contusion

intra-alveolar hemorrhage and edema

13

some clinical features to look for in pulmonary embolism

- pleuritic chest pain
- tachypnea
- atrial fibrillation

14

triad for cardiac tamponade

- distant heart sounds
- hypotension
- jugular venous distension

15

pleuritic chest pain

pain when you breathe, cough and sneeze

16

Peak airway pressure equation

Airway resistance + plateau pressure

17

plateau pressure equation

elastic pressure + positive end-expiratory pressure (PEEP)

18

How is PEEP calculated

end-expiratory hold maneuver

19

lung compliance

ability to expand

20

how does pneumonia cause hypoxemia

right-to-left intrapulmonary shunting
V/Q mismatch

21

how is theophylline meabolized

cytochrome oxidase in liver

22

antibiotic known to decrease theophylline clearance

ciprofloxacin

23

patient with acute presentation of dyspnea, chest pain, tachycardia, hypoxia, and clear lung sounds has

PE

24

most common cause of community-acquired pneumonia

strept. pneumoniae

25

on the vent, what influences O2? which one are you more likely to reduce to decrease O2

FiO2 (this one) and PEEP

26

on vent what, influences CO2

RR and TV

27

what tumor produced both alpha fetoprotein and human chorionic gonadotropin tumor marker

Nonseminomatous germ cell tumors

28

3 most common causes of chronic cough a

1. postnasal drip
2. asthma
3. GERD

29

MOA of Chlorpheniramine

H1 Antihistamine receptor blocker

30

asthma patient that has sore throat, morning hoarsness, worsening cough only at night, and increased need for her albuteral inhaler following meals also has what

GERD
