Multiple Choice

9

Multiple Choice

Prior to 2005, why were endotracheal tubes (ETTs) without cuffs routinely recommended for children less than 8 years of age?

1

Because some lung volumes are so small cuffs are unnecessary

2

Because in some infants the ETT creates a seal against the cricoid cartilage

3

Because less airway resistance develops without a cuff, promoting lower ventilation pressures

4

Because ETTs without cuffs enable pressure venting when an infant cries

12 cm at the lip

3

The cricoid cartilage in an infant acts as a partial airway obstruction.

2

A tracheotomy needs to be performed in the emergency department.

3

The child is in urgent need of transport to the operating room to be intubated.

4

Nebulized 2.2% racemic epinephrine needs to be given via face mask every 10 minutes.

At least 2 hours

2

At least 4 hours

3

At least 6 hours

4

At least 12 hours

15

Multiple Choice

Which of the following physiologic consequences would develop if the liquid–gas interface were without surfactant?

1

Large alveoli would empty into smaller ones at the end of exhalation.

2

Every exhalation would demand ventilatory muscle activity.

3

Every breath would require a considerable amount of pressure to expand the lung with each inspiration.

4

Some alveoli would collapse during exhalation.

16

Multiple Choice

Which of the following physiologic conditions results from the presence of normal amounts of pulmonary surfactant in the lung?

1

2

Uniform gas distribution during expiration occurs.
