Answer 24

you can administer 5-10 L/min

Question 25

how long should a simple mask be used for and why?

should only be used for short term (max several hours) because it causes drying of mucous membranes

Answer 26

10-15 L/min

Question 27

how long should a non rebreather mask be used for and why?

Answer 27

use for less than 1 hour because it causes rapid drying of the mucus membranes in airways

Question 28

Answer 28

1-15 L/min

Question 28

how much oxygen can you administer with a Bi-flow mask

Answer 28

Answer 29

up to 15 L/min

Question 29

what situation is a bi-flow mask ideal for

Answer 29

ideal for when a higher flow of oxygen is needed while eating since they can't wear a mask

Answer 29

less claustrophobic than an aerosol mask

Question 30

what type of patient should you not use a face tent on and why

Answer 30

should not be used on patients that require a high flow of oxygen since it has an imprecise FiO2

Question 30

if a client has a bronchodilator and a steroid ordered, which one should be given first

Answer 30

Bronchodilator first because it dilates first to open airways and the steroid can be more effective

Question 31

what does MDI stand for
