1

What is the purpose of surfactant?

prevents collapse and sticking together of lung tissues

2

This position decreases the compression of the chest due to gravity

Fowler position

3

This position is used to feed a patient on feeding precautions or to deliver a breathing treatment

High-Fowler position

4

Give 3 methods of promoting secretion clearance.

Deep breaths and coughing
Suctioning
Postural drainage

5

T/F: In suctioning, In suctioning, the nurse should utilize sterile technique

True

6

What will be the findings that the patient is responding well to bronchodilators?

Bronchodilators treat symptoms of bronchoconstriction, relaxing smooth muscles in airway thus improving airflow.

7

Llevalbuterol and albuterol are examples of what type of medications?

Short-acting beta-agonists (SABAs)

8

Anticholinergics

relax smooth muscles of airway, decrease mucous secretions by blocking parasympathetic effect

9

Theophylline (Slo-Bid) is an example of this medication.

Xanthines

10

What are the benefits of incentive spirometry?

Helps patients breathe deeply to expand the lungs
Assists in clearing of secretions and increasing oxygen delivery to bronchi and alveoli

11

Most common, comfortable method of oxygen administration.

nasal cannula

12

What important nursing care is rendered to patients with oxygen therapy?

Ensure flow is sufficient, patient comfortable, indwelling lines clear

13

T/F: Trachea primarily increases in diameter rather than length during first 5 years of life.

False

14

T/F: Oxygen consumption is higher in children than in adults because of the high metabolic rate.

True

15

H. Children under 6 years of age primarily breathe with their _____.

diaphragm

16

Lung injury caused by alveolar overdistention

Barotrauma

17

Provides inspiratory positive airway pressure as well as airway support during expiration

Bilevel ventilator (BiPAP)

18

Applies positive pressure to the airways of a patient who is breathing spontaneously.

Continuous positive airway pressure (CPAP)

19

Negative pressure ventilator

Creates negative (subatmospheric) pressure externally to draw the chest outward and air into the lungs, mimicking spontaneous breathing

20

Noninvasive positive pressure ventilation (NIPPV)

provides respiratory support by way of a tight-fitting full-face mask, nasal mask, nasal shield, or nasal pillows

21

Pneumomediastinum

lung injury caused by alveolar overdistention

22

Pneumopericardium

air in the pericardial sac

23

requires intubation; a positive pressure is maintained in the airways during exhalation and between breaths

Positive end-expiratory pressure (PEEP)

24

used more often than negative pressure ones, especially in treating patients with acute respiratory failure

Positive pressure ventilators

25

the decrease of arterial oxygen despite administration of oxygen at high flow rates

Refractory hypoxemia

26

the gradual withdrawal of mechanical ventilation when survival without assisted ventilation is not expected

Terminal weaning

27

process of removing ventilator support and reestablishing spontaneous, independent respirations

Weaning

28

Acute respiratory distress syndrome (ARDS)

rapid onset characterized by noncardiac pulmonary edema and progressive refractory hypoxemia
Extensive lung tissue inflammation and small blood vessel injury occur --> malfunction of other organs following

29

Assist-control mode ventilation (ACMV)

frequently used to initiate mechanical ventilation when the patient is at risk for respiratory arrest; assisted breaths triggered by inspiratory effort

30

Synchronized intermittent mandatory ventilation (SIMV)

allows patient to breathe spontaneously between delivered ventilator breaths

31

Pressure-support ventilation (PSV)

delivers ventilator-assisted breaths when patient initiates an inspiratory effort

32

Pressure-control ventilation (PCV)

controls pressure within airways to reduce the risk of airway trauma

33

Tidal volume

control amount of gas delivered with each breath. 400–550 mL

34

Name complications of ventilatory support.

Ventilator-associated pneumonia, barotrauma, pneumothorax, decreased cardiac output, stress ulcers, vomiting, constipation

35

Inserted to maintain a patent air passage for patient with obstructed, potentially obstructed airway

Artificial Airways

36

Used to keep upper air passages open. Easy to insert, low risk of complications

Oropharyngeal and Nasopharyngeal Airways

37

Commonly inserted in patients who have general anesthesia, emergency situations

Endotracheal Tubes

38

Patient who needs long-term airway support will be needing this type of airway management.

Tracheostomies

39

Tracheostomy care for patient will focus on _____ and ______.

maintaining patency, reducing risk of infection

40

Most common causes of ARDS in children

pneumonia, aspiration, major trauma, near-drowning, systemic infection
