Answer 2

They must be unconscious to ensure they have no gag reflex

Question 3

What is the purpose of a BVM?

Answer 3

To send air into a patient’s body who is not breathing to ensure their tissues remain oxygenated

Question 4

When attaching a BVM to an oxygen source, how high (L/min) should the flow rate of oxygen be?

Answer 4

The highest level possible

Question 5

How many breaths should you deliver per minute to a patient who needs a BVM?

Answer 5

10-12

Question 6

What is acidemia?

Answer 6

Increased ability of Hgb to release oxygen to the tissues

Question 7

What is alkalemia?

Answer 7

The decreased ability of Hgb to release oxygen to the tissues

Question 8

When would oxygen therapy be contraindicated?

Answer 8

When someone has a high SpO2 or uncontrolled administration in COPD because it may cause hypo ventilation due to decreased c02 levels in the body

Question 9

What are early signs of hypoxia?

Answer 9

Confusion, anxiety, restlessness, increased BP

Question 10

What are late signs of hypoxia?

Answer 10

Cyanosis

Question 11

List some high-flow oxygen devices:

Answer 11

Venturi mask, large-volume nebulizer and blender mask

Question 12

List some low-flow oxygen devices:

Answer 12

Nasal cannula, simple nonrebreather mask, and partial nonrebreather mask

Question 13

What is the purpose of an incentive spirometer?

Answer 13

To prevent pneumonia following surgery and allows patient to deep breathe

Question 14

What is the purpose of deep breathing and coughing?

Answer 14

To prevent pneumonia in patients who have just had a surgery or have difficulty with chest expansion

Question 15

How do you participate in “controlled coughing”

Answer 15

Take 2 deep breaths in through nose and exhale through pursed lips, then take a 3rd deep breath in, hold it for 3 seconds and then cough fully for 2 or 3 consecutive coughs without inhaling in between

Answer 17

Skin colour
LOC
Watch chest expansion
Watch for accessory muscle use during inhalation

Question 18

What is the major muscle that moves up and down with respirations called

Answer 18

Diaphragm

Question 19

What palpating is done as a part of chest assessment?

Answer 19

Symmetrical chest expansion
Lumps
Temperature
Vibrations

Question 20

What are abnormal sounds called?

Answer 20

Adventitious sounds

Question 21

How do you properly measure an oral airway?

Answer 21

Measure from the persons ear to the bottom of their jaw

Question 22

Which oxygen deliver system is appropriate for both short and long term use?

Answer 22

Nasal cannula

Question 23

When should a humidifier be used with a nasal cannula?

Answer 23

Anything thing 4L and over

Question 24

Which oxygen delivery system provides the highest rate and most precise oxygen concentration?

Answer 24

Venturi mask

Oxymizer

Question 25

What is the benefit of using a nonrebreather mask vs a partial nonrebreather mask?

Answer 25

The nonrebreather mask has a valve that shuts during inhalation and opens during exhalation to ensure oxygen and carbon dioxide are not mixed.

Question 26

What is the major benefit of the Oxymizer oxygen deliver system?

Answer 26

It only releases air upon inhalation
