EAQ Concepts of Care for Patients Requiring Oxygen Therapy
A patient is scheduled to undergo insertion of a catheter for transtracheal oxygen (TTO). Which statement by the patient indicates a need for further teaching about the procedure?
"I can use this method only when I am at home" (It may be used at home and when out in public)
A patient who smokes cigarettes is being discharged home on oxygen. The patient states, "My lungs are already damaged, so I'm not going to quit smoking." Which response would the nurse provide?
"Let's talk about why smoking around oxygen is dangerous."
Which prescription for oxygen delivery would the nurse question?
48% O2 by nasal cannula
For which reason would the nurse use caution in providing supplemental oxygen for the patient with hypercarbia?
A lower arterial oxygen level provides the stimulus to breathe
Which device is an example of a low-flow oxygen delivery system used for long-term therapy?
A nasal cannula
A patient who has thick, sticky respiratory secretions requires high-flow humidified oxygen delivery. Which oxygen delivery equipment would the nurse use for this patient?
Aerosol mask
Which laboratory test would the nurse monitor to determine a patient's ability to oxygenate?
Arterial blood gases Hemoglobin and hematocrit
A comatose patient is receiving oxygen via a simple facemask. Which nursing action is priority for this patient?
Assessing the oropharynx for secretions and vomitus
Which condition may result from vagal stimulation during tracheal suctioning?
Asystole Heart Block Bradycardia
Which oxygen device is also likely to increase ventilation?
CPAP (continuous positive airway pressure mask)
A patient has been receiving 60% oxygen by simple facemask since admission 3 days ago. Which finding alerts the nurse to an early stage of oxygen toxicity?
Chest pain Nonproductive cough GI upset
Which patient indicates a need for low-flow oxygen delivery?
Chronic hypercarbia
Which intervention would the nurse include in the plan of care for a patient receiving oxygen a 5L/min per nasal cannula?
Ensure that oxygen bubbles through the water in the humidifier
A chest x-ray is prescribed for an ambulatory patient receiving nasal oxygen. Which action would the nurse take when personnel arrive to transport the patient?
Ensure that portable oxygen is in place before the patient leaves for radiology
A patient who has a DNR order is using a nonrebreather oxygen mask, and breathing appears to be labored. Which action would the nurse take first?
Ensure that the tubing is patent and that oxygen flow is high
A patient admitted to the emergency department with facial burns and smoke inhalation requires high-flow oxygen therapy. Which oxygen delivery device would the nurse apply?
Face tent
Which mode of oxygen delivery is recommended for a patient with facial burns?
Face tent
Which respiratory device can be used to provide a patient with an 80% fraction of inspired oxygen (Fio2)?
Face tent Aerosol mask T-piece
Which condition increases oxygen demand?
Fever
What action would the nurse plan when caring for a patient who is using a nonrebreather mask?
Frequent verification that the oxygen source is functioning
A patient has a pulse oximetry level of 96% and a RR of 14 breaths/min. Oxygen is being delivered via simple facemask at a flow rate of 4L/min. Which action would the nurse take?
Increase the oxygen flow rate to 5L/min and review the HCP's orders
Which patient statement about an oxygen concentrator indicates teaching has been effective?
It does not require refilling with liquid oxygen
Which factor would be considered when determining the type of oxygen that a patient will require for home oxygen therapy?
Liquid oxygen is available in lightweight, easy-to-carry containers Liquid oxygen tanks last longer than equal-sized gaseous oxygen tanks
A patient is to receive oxygen therapy at home by nasal cannula. Which information would the nurse provide to the patient?
Lubricate the nostrils with water-soluble jelly Do not smoke or use lit candles or matches in the immediate area Cleanse the cannula by rinsing with clear warm water
Which device delivers low-flow oxygen?
Nasal cannula
Which factor would the nurse consider when determining the type of oxygen delivery system for a patient?
Need for humidification Oxygen concentration required by the patient Oxygen concentration achieved by a delivery system
Which principle would the nurse apply to planning care for a patient receiving supplemental oxygen?
Nitrogen helps prevent alveolar collapse because it does not cross over capillary membranes High levels of oxygen dilute the nitrogen in the lungs and lead to alveolar collapse
A patient with COPD is exhibiting air hunger while receiving oxygen via nasal cannula at a flow rate of 2L/min. Which treatment option would the nurse discuss with the provider?
Noninvasive positive-pressure ventilation
A patient with COPD is exhibiting increasing air hunger while receiving oxygen via nasal cannula at a flow rate of 2L/min. Which treatment option would the nurse discuss with the provider?
Noninvasive positive-pressure ventilation
Which mechanism would the nurse expect to be prescribed for a patient who has sleep apnea?
Noninvasive positive-pressure ventilation
A patient with COPD who has been receiving oxygen via nasal cannula is becoming increasingly dyspneic with increased use of accessory muscles to breathe. The nurse auscultates markedly diminished breath sounds in all lung fields. Which oxygen delivery method would the nurse recommend that the provider prescribe?
Noninvasive positive-pressure ventilation (NPPV)
Which oxygen delivery equipment could provide a fraction of inspired oxygen (Fio2) greater than 80%?
Nonrebreather mask
Which information about oxygen administration would the nurse explain to a patient who has severe heart failure?
Oxygen administration will decrease the work of the heart to deliver oxygen to vital organs
A patient is wearing a nonrebreather mask prescribed to deliver 95% fraction of inspired oxygen (Fio2). Which condition must be met to ensure that this concentration is delivered?
Oxygen flow rate should be set at 10-15L/min A one-way valve between the mask and reservoir should be open during inhalation
The nurse is discharging a patient with a prescription for continuous oxygen therapy via nasal cannula at home. Which information would the nurse include in the discharge teaching?
Pad the tubing behind the ears
Which information helps evaluate the adequacy of a patient's oxygenation?
Partial pressure of arterial oxygen (Pao 2)
Which value indicates clinical hypoxemia?
Partial pressure of arterial oxygen (Pao 2) of 50mm Hg
A lunch tray is served to a patient wearing a Venturi mask. Which action would the nurse take?
Request a prescription for a nasal cannula to be used during mealtime.
In which instance is treatment with continuous positive airway pressure (CPAP) considered less effective?
Respiratory failure after extubation
Which device is used in a low-flow oxygen delivery system?
Simple facemask Non-rebreather mask
Which goal is a purpose of oxygen therapy?
To provide an acceptable blood oxygen level
Which situation is a potential source of infection for a patient receiving oxygen therapy?
Using a heated humidifier or nebulizer Inserting an oral suction catheter in the ET tube
