Question

Hello,

could you help me with it .

55. A flowmeter has a completely closed needle valve, and the ball jumps then retums to zero when the flowmeter is plugged into a gas source. Which of the following is correct? I aBourdon gauge is being used II it is a Thorpe tube flowmeter III. it is a back-pressure compensated flowmeter IV. the needle valve is malfunctioning A B. C. D. I & IV II & III I,II & III II, III & IV 56. Which of the following are characteristics of a back pressure compensated Thorpe tube? I calibrated at 50 psi II. if gas flow from the flowmeter encounters resistance, the flow will drop III. the needle valve is located between the float (ball) and the patient (1.e. after the calibrated scale) A. B. C. D. I & III I, II & III II & III II only 57. A 10 lpm oxygen flow restrictor is being used with a He/O2 mixture. The flow of the gas through the flow restrictor is: A B. C. greater than 10 lpm less than 10 lpm 10 pm 58. Changes in depth and rate of ventilations can affect the FO, delivered by a nasal cannula To deliver a more accurate FiO2, you would substitute a(n): C A nasal catheter B. simple mask air entrainment mask D. partial rebreathing mask

Answer 1

64. The approximate Fr Oz delivered from NA → @ 60-80% Because, fils is extremelvariable. In theoretically it's capacity of delivering 1.00 but realistically it is to between 60 to 80 ) 58. Change in depth and rate of ventilations can affect the F, O2 delivered by a nasal cannel. To deliver a more accurate FiO2 , you would substitute - D. Partial rebreathing mask .. 59. A patient with chronic co, retention is admitted to the emergency room with an acute exacerbation of her Condition. The most appropriate oxygen device to useally initially is a- D. Venture mask at low concentrations. (Because, or Co2 retention with an acute exacerbation of chronic obstructive pulmonary disease. few patients developed clinically cor retention, with a controlled oxygen therapy means ventrimask to maintain the O2 saturation .) 66. When using a heated system, what is the minimum ammount that is recommended to be delivered by the AARCIS CPGS? B. 30 30myll
