Oxygen Therapy

Question 1

Nasal cannula

Answer 1

Most used to administer oxygen
Delivers concentration of 22% to50% w/ flow rate of 1 to 6 L/ ml
Used for pts who are non critical w/ minor breathing problem who cant or will not wear a mask. It administer low- flow oxygen humidification is rarely

Question 2

Simple mask

FIO2 35% to 65%

Answer 2

This device requires fairly high Oxygen flow to prevent rebreathing of carbon dioxide.
Don’t use a flow rate lower than 6 L/ ml with this type of mask ( CO2 can build up in the mask at low rates)
Consider humidification to keep theta mucous membranes from becoming dry.

Question 3

Nonrebreather face mask

Answer 3

Used to deliver high flow rates and high concentrations of oxygen
Do not allow the reservoir bag to deflate, if deflate the patient is likely to breathe in large amount of exhale carbon dioxide

Question 4

Venturi mask

Answer 4

It is used for pts who have COPD when an accurate F iO2 is essential and carbon dioxide build up must be keep at a minimum. Humidifiers are not used with this device. Most used for critical ill patients

Question 5

Manual resuscitation bag

Answer 5

Provides high concentration of oxygen to a pt prior to a procedure such as suctioning or intubating and during respiratory or cardiac arrest

Question 6

Early stage of hypoxia

Answer 6

Restless, confused, anxiety, elevated high blood pressure, increase heart rate, increase respiratory rate, and dyspnea

Question 7

Late sign of hypoxia

Answer 7

Decrease level of consciousness, decrease activity level, hypotension, bradycardia, metabolic acidosis, and cyanosis

Question 8

Chronic hypoxia

Answer 8

Clubbing or fingers and toes, peripheral edema, right-side heart failure, respiratory acidosis, oxygen saturation 87%

Question 9

Face tent mask

Answer 9

Pts who have trouble breathing of fee lack to air

Humidifier is a must in order to maintain the mucous membrane close

Question 10

Tracheostomy collar

Answer 10

A tracheostomy collar is designed to provide high humidity and the oxygen concentration prescribe.

Question 11

Flow meter

Answer 11

Turn the knob all the way to the left provides maximal oxygen flow.
Turning the knob all the way to the right stops the flow of oxygen from the cylinder to the patient.

Question 12

Preparing to insert a straight urinary catheter for a male patient what should the nurse do

Answer 12

Apply light traction to the penis.
It position the penis to a perpendicular to the body while light traction straightens the urethral canal to facilitate the catheter insertion
