Oxygen delivery devices- Exam Questions with Correct Answers
(Grade A+)
Question 1: indications for supplemental oxygen use
Answer: •Hypoxia •Post op •Pain •Respiratory disorders causing build up of secretions •Poor circulation
Question 2: early s/s of hypoxia
Answer: restlessness, anxiety, tachycardia, tachypnea, dyspnea, hypertension
Question 3: late s/s of hypoxia
Answer: - Confusion - Bradycardia - Hypotension - Cyanosis - decreased activity level
Question 4: chronic s/s of hypoxia
Answer: clubbing of the fingers and toes peripheral edema right sided heart failure respiratory acidosis
oxygen saturation <87%
Question 5: pulse oximetry
Answer: •Noninvasive method to monitor oxygen carrying capacity of RBC's
Question 6: normal spO2 levels (oxygen saturation)
Answer: 95-100%
Question 7: nasal cannula
Answer: •Most frequently used •Provides 02 concentrations of 22 - 50% with flow rate of 1 - 6 L/min •02
concentration depends upon flow rate and patients' respiratory rate, rhythm, and depth •Rarely requires
humidification
Question 8: simple oxygen mask
Answer: •Used for those needing a higher flow of oxygen for a short time period •Provides 02
concentrations of 40 - 60% with flow rate of 6 - 10 L/min •Often requires humidification •do not use at rates
less than 6 l/min due to risk of C02 buildup
Question 9: non rebreather mask
