• nasal catheter
• transtracheal catheter
• simple face mask
• partial rebreathing mask

Question 2: What color is an oxygen tank in the United States?

Egan's p.848

Answer:

Green Question 3: Variables that raise the FiO2 received from a Low-Flow O2 system include: Egan's p.877

Answer:

increased O2 output, Mouth-closed breathing, low inspiratory flow, slow respiratory rate

Question 4: List 2 indications for the use of oxygen therapy

Egan's p. 869

Answer:

• PaO2<60 2.SaO2/SpO2<90%on room air 3.Severe Trauma 4.Acute MI 5.Postanesthesia

Question 5: Oxygen toxicitiy primarily affects which branch of the nervous system Egan's p.870

Answer:

The Central Nervous System (CNS)

Question 6: What is the tank conversion factor for an

e cylinder filled with oxygen?Egan's p.851

Answer:

conversion factor is 0.28

Question 7: What causes Retinopathy of Prematurity?

Egan's p.871

Answer:

retinopathy of Prematurity is caused when low-birth-weight and/or premature infants receive too much supplemental oxygen Question 8: What risk is posed by providing supplemental oxygen at an FiO2 greater than 50%?Egan's p.872

Answer:

FiO2s greater than 50% can lead to Nitrogen wash out resulting in Absorption atelectasis

Question 9: Names 2 types of oxygen enclosures

Egan's p.888

Answer:

oxygen tent and oxygen hood Question 10: Variables that lower the FiO2 received from a Low-Flow O2 system include: Egan's p. 877

Answer:

Low O2 output, Mouth-open breathing, Rapid respiratory rate

Question 11: What is the formula used to determine the length of time a cylinder of oxygen with 2000psi will last at 4 liters per minute?Egan's p.851

Answer:

the answer is 2000 X 0.28 = 560 divide the answer by the liter flow 560/4 = 140 minutes or 2 hours 20 minutes Question 12: What effect does too much supplemental oxygen have on a patient with COPD?Egan's p.871

Answer:

Too much oxygen for a COPD patient can cause a depression in ventilation by "knocking out" their hypoxic drive

Question 13: Why is the minimum setting of a Nonrebreathing mask 10 liters?

Egan's p.874

Answer:

To prevent the reservoir bag from collapse on inspiration Question 14: What effect does supplemental oxygen have on the heart of a hypoxemic patient?Egan's p.868

Answer:

Supplemental oxygen reduces the need for an increase in cardiac output to meet tissue demand

Question 15: What is the flow range for a simple mask?

Answer:

5-10 liters per minute Question 16: What are the pin locations on an oxygen tank using the pin-index safety system?Egan's p.857

Answer:

The pin index hole positions are 2 and 5

Question 17: What is the proper flow range for an adult using a nasal cannula?

Egan's p. 874

Answer:

0.25-8 liters per minute

Question 18: Define High-Flow oxygen system?

Egan's p.880

Answer:

A high flow oxygen system is defined as a system that meets or exceeds the amount of oxygen required by the patient

Question 19: List the 3 clinical objectives for oxygen therapy

Egan's p.868

Answer:

1.Correct documented/suspected acute hypoxemia 2.Decrease the symptoms of hypoxiemia 3.Decrease the work of the heart related to hypoxemia Question 20: Symptoms of mild/moderate hypoxemia involving the respiratory system Egan's p.870

Answer:

• Tachypnea
• Dyspnea/SOB 3.Pale skin color
