Oxygen Therapy (ATI) EXAM 1 – Flashcards

A patient has been receiving O2 PRN nasal cannula for 4hrs. which of the following assessment findings help indicate O2 therapy has been effective? -respiratory rate 14/min -SaO2 90% -cardiac output 5.6 -paCO2 68 mmHg

pt admitted with community acquired pneumonia has been receiving O2 therapy for several days. Which of the following assessment findings indicates an adverse effect of O2 therapy? -poor skin turgor -cracks in oral mucosa -elevated heart rate -copious respiration secretions

administering O2 therapy with a non-rebreather mask has which of the following advantages? -offers highest O2 concentration of the low flow system -it is designed of safety one mask valves & flaps are sealed -incorporates a design that requires minimal monitoring of pt -provides O2 concentration of 40-60%

a nurse is caring for a pt who is dyspneic & 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? -assessment -diagnosis -planning -evaluation

a home health nurse is instructing a patient who has just started receiving O2 therapy via mask. The nurse should emphasize that the pt must: -clean the mask with soapy water every other day -reposition the elastic band frequently -apply petroleum jelly around and inside the nares -make sure there is adequate consideration in the tubing

a nurse is providing discharge teaching to a pt who will continue O2 therapy at home. The nurse should instruct the patient that turning the knob on the O2 flow meter all the way to the right: -starts the flow of O2 -provides maximal O2 flow -provides minimal O2 flow -stops the flow of O2

a nurse is caring for a critically ill pt with COPD who requires delivery of a precise concentration of O2. which of the following type of O2 delivery device is indicated for this pt? -simple face mask -nasal cannula -face tent -venturi mask

a nurse should recognize that which of the following is an indication for O2 therapy? -resp. rate 32/min; anxiety -dyspnea; PaO2 90mmHg -chest pain; FiO2 65% for 4 days -tachypnea; SaO2 90%

a nurse is caring for a pt who has a tracheostomy. Which of the following must the nurse use when administering O2 therapy to this pt? -distilled water for humidification -tracheostomy collar -an inner tracheostomy cannula -an aerosol mask

O2 therapy is prescribed to a pt who came to the ER with EARLY stages of hypoxia. When assessing this pt, the nurse should expect to find which of the following indicators? -elevated BP -decreased resp. rate -cyanosis -peripheral edema

what are the 3 stages of hypoxia?

early stages of hypoxia:

late stages of hypoxia:

chronic stages of hypoxia:
