22
Q

What distinguishes hypoxemia from hypercapnia?

A

Hypoxemia is low oxygen in the blood; hypercapnia is elevated CO₂ in the blood.

23
Q

What are the three infection types related to influenza?

24
Q

What is the most common cause of community-acquired pneumonia?

A

Streptococcus pneumoniae.

25
What are the expected clinical manifestations of bacterial pneumonia?
Fever.
26
What are the expected clinical manifestations of atypical pneumonia?
Low-grade fever.
27
What organism causes tuberculosis (TB)?
Mycobacterium tuberculosis.
28
A granulomatous lesion containing macrophages
Ghon complex in TB
29
What is the screening test used to detect TB exposure?
Tuberculin Skin Test (TST) using purified protein derivative (PPD).
30
What are risk factors for lung cancer?
Smoking.
31
Which type of lung cancer has the poorest prognosis?
Small cell lung cancer.
32
What are the expected clinical manifestations of lung cancer?
Chronic cough.
33
What is the difference between croup, epiglottitis, and acute bronchiolitis in children?
Croup causes a barking cough.
34
What is a pleural effusion and its common causes?
Fluid in the pleural space caused by CHF.
35
What distinguishes an open pneumothorax from a tension pneumothorax?
Open allows air in and out; tension traps air.

What are the types of obstructive airway disorders?
Asthma Emphysema Chronic bronchitis Chronic obstructive pulmonary disease
37
Air trapping from alveolar overdistention increases the anterior-posterior diameter.
Barrel chest in emphysema
38
Genetic mutation in chloride transport leading to thick mucus and obstructed airways.
pathogenesis of cystic fibrosis
39
What is the gold standard for diagnosing active TB?
Sputum culture for acid-fast bacilli.
40

Pulmonary embolism
41
What are the three major risk factors for pulmonary embolism?
Venous stasis Vessel injury Hypercoagulability
