ATI Testing Oxygen Therapy

question

A nurse is caring for a patient who has a tracheostomy. Which of the following must the nurse use when administering oxygen to this patient?
answer

A tracheostomy collar -A tracheostomy collar is designed to provide high humidity and the oxygen concentration prescribed for the patient. IT is a small oxygen-delivery apparatus that fits over the tracheostomy site and is held in place by an adjustable elastic strap that fits around the patient’s neck.
question

A nurse is caring for a patient who is dyspneic and slightly cyanotic, with a respiratory rate of 28/min. The nurse determines that the patient has impaired gas exchange during which of the following phases of the nursing process?
answer

Diagnosis -During the diagnosis phase, the nurse analyzes and interprets data gathered from the nursing assessment to formulate a nursing diagnosis, in this case, impaired gas exchange.
question

A nurse should recognize that which of the following is an indication for oxygen therapy?
answer

Tachypnea; SaO2 90%
question

A nurse is caring for a critically ill patient with COPD who requires delivery of a precise concentration of oxygen. Which of the following types of oxygen-delivery device is indicated for this patient?
answer

Venturi mask -A venturi mask is most often used for critically ill patients who require administration of a specific concentration of oxygen. Because this device delivers a precise oxygen concentration and carbon dioxide buildup is minimal, it is commonly used for patients who have COPD

answer

reposition the elastic band frequently.
question

A patient has been receiving oxygen PRN via nasal cannula for 4 hr. Which of the following assessment findings helps indicate that oxygen therapy has been effective?
answer

Respiratory rate 14/min =The normal range of respirations is 12 to 16/min. Stabilization of the RR, especially if the patient was previously tachypneic, is an indication that oxygen therapy is effective.
question

A patient admitted with community-acquired pneumonia has been receiving oxygen therapy for several days. Which of the following assessment findings indicates an adverse effect of oxygen therapy?
answer

cracks in the oral mucosa.
question

Administering oxygen therapy with a nonrebreather mask has which of the following advantages?
answer

Offers the highest oxygen concentration of the low-flow systems. -A nonrebreather mask delivers oxygen concentrations greater than 90%. Thus, it provides a higher fraction of inspired oxygen than a nasal cannula (also low-flow, but delivering about 24-44%) or a simple mask (low-flow, delivers 40-60%)
question

A patient who is prescribed oxygen therapy 24hr/day is concerned about being confined to bed. Which of the following should the nurse do to provide mobility for this patient?
