Question 7

What is the purpose of humidification in oxygen therapy?

Answer 7

Helps alleviate a sore, dry, and bloody nose by adding humidity to the oxygen

Achieved through a water bottle connected to the concentrator or liquid system.

Question 8

What is the Acapella device used for?

Answer 8

Improves clearance of secretions

Question 9

What is the purpose of huff cough?

Answer 9

-A technique used to help clear airways
-Clears sputum

Question 10

What is the benefit of purse-lip breathing?

Answer 10

Prevents bronchiolar collapse and air trapping

Useful for patients with obstructive airway diseases.

Question 11

What does vibration do in respiratory therapy?

Answer 11

Mobilizes secretions

Can be part of therapies to clear airways.

Question 12

What is diaphragmatic breathing?

Answer 12

Use of diaphragm instead of accessory muscles to achieve maximum inhalation and slow respiratory rate

Promotes better oxygen exchange.

Question 13

How long should suctioning be performed?

Answer 13

10-15 seconds or until oxygen saturation goes down

Important to prevent hypoxia during the procedure.

Question 14

What are common symptoms of Iron deficiency anemia?

Answer 14

Fatigue and activity intolerance due to inadequate oxygen

Affects overall energy levels and physical activity.

Question 15

What position should the head of the bed be elevated to aid lung expansion?

Answer 15

Semi-fowlers

Question 16

What is the recommended coughing frequency while awake?

Answer 16

Every 1-2 hours

Helps to keep airways clear.

Question 17

What is Thoracentesis?

Answer 17

Taking a long needle to clear liquid in the lungs

A procedure used to relieve pleural effusion.

Question 18

What is the normal inspiration/expiration ratio?

Answer 18

1-2

Indicates normal respiratory function.

Question 19

What defines chronic respiratory issues?

Answer 19

Symptoms lasting over 6 months

Important for diagnosis and treatment planning.

Question 20

What is atelectasis?

Answer 20

Lung collapse

Atelectasis can occur due to various reasons, including obstruction or pressure on the lung.

Question 21

Define cyanosis.

Answer 21

Blue discoloration

Cyanosis indicates inadequate oxygenation in the blood.

Question 22

What does clubbing of the fingers indicate?

Answer 22

Clubbing of the fingers is often a sign of chronic hypoxia

It can be associated with conditions like COPD and lung diseases.

Question 23

What are hypoxia and hypoxemia?

Answer 23

Hypoxia is low oxygen in tissues; hypoxemia is low oxygen in the blood

Both conditions can lead to serious health issues.

Question 24

What is exacerbation in the context of respiratory conditions?

Answer 24

Worsening of symptoms

Exacerbations can lead to increased difficulty in breathing and require medical intervention.

Question 25

Define perfusion.

Answer 25

How much blood and oxygen is getting to the tissue ## Footnote Adequate perfusion is crucial for organ function.

Question 26

What is Cheyne-Stokes respiration?

Answer 26

Rapid breathing followed by slow breathing ## Footnote This pattern can indicate severe medical conditions.

Question 27

What is orthopnea?

Answer 27

Difficulty breathing while laying down ## Footnote Patients often need to sit up to breathe comfortably.

Question 28

What does apnea mean?

Answer 28

No breathing ## Footnote Can occur in various medical conditions, including sleep apnea.

Question 29

Define bradypnea.

Answer 29

Slow breathing ## Footnote It can be a sign of respiratory distress or other medical issues.

Question 30

What is the target oxygen saturation for COPD patients?

Answer 30

88-92% ## Footnote Too much oxygen can be harmful to COPD patients.

Question 31

What is hemoptysis?

Answer 31

Coughing up blood ## Footnote Hemoptysis can indicate serious underlying conditions.

Question 32

What does greenish/yellow sputum indicate?

Answer 32

Signs of infection ## Footnote Sputum color and odor can provide clues about respiratory infections.

Question 33

What is hyperventilation?

Answer 33

Breathing really fast, inhaling too much oxygen ## Footnote This can lead to decreased carbon dioxide levels in the blood.

Question 34

What are accessory muscles?

Answer 34

Muscles used to assist in breathing, such as the diaphragm ## Footnote Accessory muscle use indicates increased work of breathing.

Question 35

Why is it important to monitor vitals and level of consciousness (LOC)?

Answer 35

To assess respiratory and overall health status ## Footnote Changes can indicate deterioration in a patient's condition.

Question 36

What is the purpose of raising the head of the bed in respiratory distress?

Answer 36

To facilitate easier breathing ## Footnote Fowler's position is often used for patients with respiratory issues.
