What is the appropriate value for the Venturi mask? Oxygen delivery devices with percent of oxygen delivered
- A. 1-6 L/min = 24%-44% O2
- B. 5-8 L/min = 35%-55% O2
- C. 4-10 L/min = 24%-55% O2
- D. 6-12 L/min = 60%-90% O2
- E. 6-15 L/min = 70%-100% O2
Correct Answer: C
Rationale: Venturi mask delivers 4-10 L/min = 24%-55% O2, as per the table: Nasal cannula (1-6 L/min = 24%-44% O2), Simple face mask (5-8 L/min = 35%-55% O2), Venturi mask (4-10 L/min = 24%-55% O2), Partial rebreather mask (6-12 L/min = 60%-90% O2), Nonrebreather mask (6-15 L/min = 70%-100% O2).

When suctioning a tracheostomy suction may be applied for a maximum of ____ seconds at a time never longer.
Correct Answer: 10
Rationale: Suctioning should be done for a maximum of 10 seconds at a time. Prolonged suctioning depletes oxygen supply.
Which of the following is an appropriate nursing measure when performing tracheostomy care?
- A. Wear clean gloves.
- B. Insert the catheter without suction.
- C. Suction for 1 minute before removing the catheter.
- D. Place the used catheter in a plastic shield for later use.
Correct Answer: B
Rationale: Insertion of the suction catheter without suction reduces the probability of tissue injury. Sterile gloves should be used for tracheostomy care. Suctioning should be done for a maximum of 10 seconds at a time. A used catheter should be disposed of appropriately.
The nurse is caring for a patient with an endotracheal tube. What interventions will the nurse implement?
- A. Change or clean all respiratory therapy equipment every 24 hours.
- B. Turn and reposition the patient every 2 hours.
- C. Provide constant airway humidification.
- D. Encourage intake of fruits and vegetables.
- E. Elevate the head of the bed.
Correct Answer: B,C,E
Rationale: Nursing interventions for the patient with an endotracheal tube include turning and repositioning every 2 hours for maximal ventilation and lung expansion, constant airway humidification and elevation of the head of the bed to assist with ventilation. Equipment should be changed or cleaned at least every 8 hours. Patients with endotracheal tubes are allowed nothing by mouth (NPO). It is necessary to provide parenteral or enteral nourishment.

A patient has a new health care provider's order for oxygen administration at 2 L via nasal cannula. Who can initiate implementation of this order?
- A. RN
- B. UAP
- C. Respiratory therapist
- D. EMT
- E. Nutritional specialist
Correct Answer: A,C,D
Rationale: Oxygen therapy may be initiated by a respiratory therapist, a nurse, an emergency medical technician (EMT), or any other licensed health care provider with an appropriate order for the oxygen. In some facilities, there is a respiratory care department, staffed by respiratory therapists who assume the responsibility of administering oxygen and delivering treatments that will improve a patient's ventilation and oxygenation. Adjustment of the oxygen flow rate is not delegated to UAP nor nutritional specialist.
