True or False
In order for the NonRebreather to work properly the reservoir bag needs to be at least 1/4 full.
False: The reservoir bag needs to be at least 2/3 full
200
True or False
The Venturi mask is the most accurate form of oxygen delivery.
True
A Venturi mask can deliver accurate oxygen concentrations from 24% to 50% with flow rates from 4 to 10 L/min.
300
In order to assist in directing flow of oxygen into patient’s upper respiratory system, the nasal prongs of the nasal cannula should face.
downward position
300
True or False
On the flow meter, the ball should float above the line of the desired liters of oxygen you want to deliver.
False, The ball should float in the middle of the line.

Muscles other than the diaphragm and intercostal muscles that may be used for labored breathing. An early sign of hypoxemia
Accessory Muscles
300
True or False
Nonrebreathers have valves and ports on them.
True
300
True or False.
The Venturi Mask does not cause a build up of CO2, making it a good mask for patients with COPD
True
It is used for patients who have COPD when an accurate FiO₂ is essential and carbon dioxide buildup must be kept to a minimum.

Skin breakdown with prolonged oxygen therapy via nasal cannula is common. One intervention to prevent breakdown would be to ________
Place cannula tubing over the patient’s ears and tighten under the chin

1. Incorrect SPO2 probe placement
2. Nail Polish
3. Low hemoglobin
4. Hypothermia

Early signs of hypoxemia include restlessness, anxiety, and agitation, left untreated the patient can progress to a state of near-unconsciousness or insensibility. The medical term for a state of near-unconsciousness or insensibility is.
Stupor
400
Patient with ___________ & ______________ may not tolerate the NonRebreather well.
Anxiety and Claustrophobia
400
Flowmeter settings to reach the desired amount of FIO2 using the Venturi mask are found....
On the Adapters.
At the base of the mask and connected to the tubing are color-coded adaptors. Each adaptor is marked to tell which specific oxygen concentration the patient will receive and at what liter flow rate to set the oxygen.
Different manufacturers may use different colors for adaptors, so it is always important to check the oxygen prescription and look carefully to see which adaptor should be used. Some Venturi masks may have one adaptor which can be easily dialed or turned to deliver a different FIO₂.
