200
Oxygen devices are connected to the wall above a patient bed to this device.
What is the Flow meter?
200
The medical term used to describe an elevated heart rate. An early sign of hypoxemia.
Tachycardia
200
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 60% with flow rates from 4 to 12 L/min.
300
The direction nasal prongs of the nasal cannula should face in order to assist in directing flow of oxygen into patient’s upper respiratory system.
What is the 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.
300
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.
400
Skin breakdown with prolonged oxygen therapy via nasal cannula is common. This is the correct placement of the tubing.
What is place cannula tubing over the patient’s ears and tighten under the chin?
400
Possible causes of Low Spo2 Readings include: (select all the apply)
1. Incorrect SPO2 probe placement
2. Nail Polish
3. Low hemoglobin
4. Hypothermia
5. Movement
Answer: ALL.
400
Early signs of hypoxemia include restlessness, anxiety, and agitation, left untreated the patient can progress to a state of near-unconsciousness or insensibility. This is the medical term for a state of near-unconsciousness or insensibility.
What 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.
500
The main cause of prongs causing pressure as well as displacement of the tubing.
What is short oxygen tubing?

Patients and their caregivers should be educated to avoid use of petroleum products such as petroleum jelly when using oxygen.
True
Flammable

Nursing considerations for a patient on a nonrebreather are: (Select all that apply)
1. Keep reservoir bag deflated
2. Assess for proper fit and seal over nose and mouth
3. Use with cause for patients at high risk for aspiration and airway obstruction
2/3
