Answer

Pleural movement

Answer

Gas exchange

Question 2

Accepted Answer

Larynx

Answer

Alveoli

Answer

Bronchioles

Answer

Pleural space

Question 3

Which zone moves air but does not exchange gas?

Accepted Answer

Conducting zone

Answer

Pleural zone

Answer

Alveolar zone

Answer

Respiratory zone

Question 4

What can an artificial airway bypass?

Accepted Answer

Upper-airway conditioning

Answer

Alveolar macrophages

Answer

Pleural membranes

Answer

Type II cells

Question 5

If airway diameter decreases, resistance usually:

Accepted Answer

Increases

Answer

Becomes gas exchange

Answer

Disappears

Answer

Decreases

Question 6

A trach patient has thick secretions. What should this make the RT think about?

Accepted Answer

Humidification and secretion clearance

Answer

Pleural membranes

Answer

More surfactant

Answer

Vocal cord movement

Question 7

A high-pitched sound near the throat points first toward the:

Accepted Answer

Upper airway

Answer

Pleural space

Answer

Respiratory zone

Answer

Alveoli

Question 8

A musical expiratory sound from deeper airways suggests:

Accepted Answer

Lower-airway narrowing

Answer

Pleural movement

Answer

Surfactant production

Answer

Upper-airway filtration

Question 9

Bronchiole narrowing usually affects:

Accepted Answer

Airway resistance

Answer

Vocal cord position

Answer

Alveolar macrophages

Answer

Upper-airway warming

Question 10

A distal lung problem where O2 and CO2 exchange occurs is in the:

Accepted Answer

Respiratory zone

Answer

Upper airway

Answer

Conducting zone

Answer

Larynx

Question 11

Two patients are short of breath: throat-area noise vs deeper musical expiratory noise. What matters first?

Accepted Answer

Location of the problem

Answer

Same treatment for both

Answer

Surfactant level first

Answer

SpO2 only

Question 12

Best comparison: laryngospasm vs bronchospasm.

Accepted Answer

Laryngospasm is upper airway; bronchospasm is lower airway

Answer

Bronchospasm is above the vocal cords

Answer

Both happen in alveoli

Answer

Both are respiratory-zone problems

Question 13

A patient has normal SpO2 but uses accessory muscles. What should the student recognize?

Accepted Answer

Work of breathing may be increased

Answer

The airway is fully normal

Answer

Gas exchange is impossible

Answer

Breathing is definitely easy

Question 14

Which statement corrects a common misconception?

Accepted Answer

Normal SpO2 can still occur with increased effort

Answer

All airway noise means bronchospasm

Answer

Upper airway only moves air

Answer

Conducting zone exchanges gas

Question 15

Best Week 1 anatomy rule for clinical reasoning?

Accepted Answer

Locate it. Explain it. Apply it.

Answer

Treat all sounds the same

Answer

Memorize every word equally

Answer

Start with treatment first
