NUR 280 Exam #3 (Chapters 21 & 23)
correctly answered to pass
Nasal cannula - correct answer ✔✔-Indicated for low-flow, low-percentage supplemental oxygen
-Flow rate of 1-6 L/min
-Delivers 25%-45% oxygen
-Patient can eat, drink, and talk
-Extended use can be very drying; use with a humidifier if over 4 L/min
-Never more than 2-3 L/min to COPD, CF
Nasal cannula (flow rate in L/min to percent Fio2 delivered) - correct answer ✔✔1 L/min = 25% FiO2
2 L/min = 29% FiO2
3 L/min = 33% FiO2
4 L/min = 37% FiO2
5 L/min = 41% FiO2
6 L/min = 45% FiO2
Simple face mask - correct answer ✔✔-Indicated for higher percentage supplemental oxygen
-Flow rate of 6-10 L/min
-Delivers 35%-60% oxygen
-Lateral perforations permit exhaled CO2 to escape
-Permits humidification
,-Increased delivered need for short period (<12 hours)
-5 L/min is minimum setting b/c of risk of retaining CO2
Simple face mask (flow rate in L/min to percent FiO2 delivered) - correct answer ✔✔6 L/min = 35% FiO2
7 L/min = 41% FiO2
8 L/min = 47% FiO2
9 L/min = 53% FiO2
10 L/min = 60% FiO2
Partial nonrebreather mask - correct answer ✔✔-Permits conservation of O2
-Set flow rate so mask remains 2/3 full during inspiration
-6-15 L/min = 70%-90%
Nonrebreather mask - correct answer ✔✔-Indicated for high percentage FiO2 (highest concentration of
O2)
-Incorporates use of reservoir bag
-Flow rate of 10-15 L/min (maintain this so reservoir bag collapses only slightly during inspiration)
-Delivers up to 100% oxygen
-One-way flaps prevent entrainment of room air during inspiration and retention of exhaled gases
(namely CO2) during expiration
Nonrebreather mask (flow rate in L/min to percent FiO2 delivered) - correct answer ✔✔10-15 L/min =
80%-100% FiO2
*Both flaps removed results in lower (80%-85%) FiO2
, *One flap removed results in higher (85%-90%) FiO2
*Both flaps in place results in maximum (95%-100%) FiO2
Venturi mask (venti-mask) - correct answer ✔✔-Indicated for precise titration of percentage of oxygen
-Flow rate of 4-8 L/min
-Delivers 24%-60% oxygen
-Uses either a gradual dial set to desired FiO2 or colored adapters selected to deliver desired FiO2
-Check that air intake valves are not blocked by clothes
Venturi mask (flow rate in L/min to percent FiO2 delivered) - correct answer ✔✔Blue = 24%
White = 28%
Orange = 31%
Yellow = 35%
Red = 40%
Green = 60%
Oxygen tent - correct answer ✔✔-Should be less than 10 L/min
-For children who need a cool and highly humidified airflow (pneumonia)
-Check linens and gown for wetness
-Check temperature
-Does not allow maintenance of a satisfactory or precise O2 concentration
Normal respiratory pattern - correct answer ✔✔Regular and comfortable, 12 to 20 breaths per minute
