RESP FINAL EXAM Questions with accurate answers. 100% Verified predictor questions You are using an E cylinder with 1600 PSI is used to provide oxygen to a simple mask running at 5 L/min during a transport to the Radiology Department. That cylinder will last ? a. 8.9 hours b. 89 min c. 68 min d. 56 min - ✔✔-b. 89 min 1600 * 0.28 / 5L Which of the following will decrease the FIO2 deliver by a low flow O2 system? I. short inspiratory time II. fast rate of breathing III. lower O2 input IV. large min ventilation a. I,II, and I b. All the above c. II, and IV d. III and IV - ✔✔-b. All the above short inspiratory time fast rate of breathing lower O2 input large min ventilation Which of the following oxygen delivery modalities could provide the highest FIO2 in an emergency situation ? a. simple mask b. nasal cannula c. partial rebreather d. non rebreather - ✔✔-d. Non rebreather Most concentrated FIO2 because of the one way valves that allow the exhalation of CO2 but does not let room air into the mask preventing O2 dilution Which medical gas should be administered during surgery to prevent the patient from becoming hypoxic ? a. compressed ait b. nitric oxide c. carbon dioxide d. helium e. oxygen - ✔✔-e. Oxygen hypoxic = inadequate supply of oxygen At -183 'C, which of the following gasses exist as a pale, bluish liquid that slightly heavier than water? a. air b. nitrous oxide c. oxygen d. carbon dioxide - ✔✔-c. Oxygen In Egan's textbook Which of the following statements are true about the DISS Connector system ? I. it is used in the connection between regulators and humidifiers II. it is used at the gas outlets between blenders and ventilators IV. it is a safety system that used to connect a regulator to H cylinder V. it uses a yoke with an arrangement of pins that correspond to specific gas mixtures a. I & II only b. II only c. III & IV d. II & IV only - ✔✔-a. I & II only As gas temperature increases, its capacity to hold water will? a. increase b. remain unchanged c. decrease d. may both increase and decrease - ✔✔-a. Increase When discussing the physical properties of oxygen; which of the following statements are true when it is used as a medical gas ? I. it is colorless as a gas and light blue as a liquid II. it is much lighter than room air III. it is classified as flammable IV. some combustible such as some oils and greases will burn with nearly explosive force in its presence V. it is responsible for the process of oxidation and the formation of oxidation and the formation of oxidants on metal elements a. I, II, & V only b. I, II, & III only c. II, IV, & V only d. I, IV, & V only - ✔✔-d. I, IV, & V only it is colorless as gas and light blue as a liquid some combustive such as some old and greases will burn with nearly explosive force in it presence. It is responsible for the process of oxidation and the formation of oxidation The total water content in a given gas when compared with the capacity for a water content in the given gas at a given temperature known as: a. relative humidity b. humidity deficit c. body humidity d. absolute humidity - ✔✔-a. Relative humidity A COPD patient is being transported to x-ray with an E-cylinder and is receiving oxygen via nasal cannula at 2 Lpm. The pressure reading in the tank is 1600 psi. how long will the cylinder last: a. 3.37 hours b. none of the above c. 165 min d. 240 min - ✔✔-a. 3.73 hours 1600 * 0.28 / 2 = 3.73 An individual experiences altitude sickness after landing at Omagodo A'Bandito Airport (4,334 meters above sea level) which of the following offers the best explanation to why this occurred? a. the barometric pressure is higher than a sea level b. there is lead oxygen in the atmosphere there than at sea level c. there is more CO2 in the atmosphere there than at sea level d. the barometric pressure is lower than at sea level - ✔✔-d. the barometric pressure is lower than at sea level sea level high = low barometric pressure sea level low = high barometric pressure The physician on the oncology floor has requested that you administer an 80% helium and 20% oxygen mixture to a patient with a large bronchial tumor. Which of the following pieces of equipment would you NOT need to administer this therapy? a. oxygen analyzer b. non rebreather mask c. oxygen flow meter d. venturi mask - ✔✔-d. Venturi mask because you don't need fixed FIO2 How would you prevent a patient with chronic hypercabia from developing oxygen induced hypoventilation ? a. ambulate patient as quickly as possible. Have patient breath fast and deep b. titrate FIO2 to highest possible SpO2 c. Maintain levels of PaO2 in the 95-99 mmHg range d. limit O2 to minimum necessary with target SpO2 of 88% -92% - ✔✔-d. limit O2 to minimum necessary with target SpO2 of 88% - 92% Mr. Martin is on a nasal cannula at 6 l/min. What size cylinder, when full would be the most appropriate for use during patient transportation across town (around 10 miles) to another hospital a. E b. D c. H d. G - ✔✔-a. E cylinder Oxygen concentrators operation involves all the following except which one? a. they have filters which require routine care b. they are electrically powered with limited portability c. they provide 100% oxygen on high flow rates d. they remove nitrogen from the room air - ✔✔-c. They can provide 100% oxygen at high flow rates A 27 year old woman received from the emergency department is on a nasal cannula at 5 L/min. Approximately what FIO2 is this patient receiving ? a. 38% - 39% b. 24% - 25% c. 40% - 45% d. 15% - 21% - ✔✔-a. 38% - 39% Mr. Jones is your home care patient and he has a problem with his liquid O2 system. so he has changed over to his H-cylinder.
