THERAPIST MULTIPLE-CHOICE EXAMINATION: PRACTICE TEST The physician orders a 35% aerosol mask to be set up for a patient who requires an inspiratory flow of 42 L/min. What is the minimum flow rate to which the flowmeter must be set to meet this patient's in- spiratory flow demands? A. 6 L/min B. 8 L/min C. 10 L/min D. 12 L/min - ANSWER B, The air/O2ratio for a 35% oxygen mixture is 5 : 1. To calculate total flow output from this device, add the ratio...

General Chemistry 2 Final Exam Questions and Answers | Latest Version | 2024/2025 | Graded A+ What determines the direction in which a chemical equilibrium will shift when the concentration of one of the reactants is increased? The equilibrium will shift to the right, towards the formation of more products, to counteract the increase in reactant concentration.
