rcp 180 Exam 3 questions with complete solutions

Early mobilization of patients on vent can decrease what correct answer: Decrease ICU acquired weakness Single best indicator of alveolar ventilation correct answer: is a measurement of Arterial pco2 When C02 rises by ten, pH will decrease by . . correct answer: 0.08 It is important that patients on a ventilator receive appropriate management of . correct answer: appropriate pain management and sedation Know what happens to pH when C02 and Hc03 change. correct answer: respiratory acidosis if PCO2 increases PH decreases metabolic acidosis if Hco3 decreases PH decreases Know what happens to ABGs when vent changes are made (Vt, RR, Fi02, PEEP) correct answer: to reduce paco2= increase respiratory rate and tidal volume to increase pao2=increase fio2 or peep Pplats, according to the book, should be kept <28-30 (in class, I stress <30 . correct answer: < 30 in class <28-30 by the book More mechanical deadspace increases PaC02 correct answer: a decrease in paco2= decrease mechanical dead space or increase tidal volume # a increase paco3= increase mechanical dead space or decrease tidal volume minute volumes of _________ are required to maintain a normal PaCO2 correct answer: 80-100 mL/kg/min What are the three scalars commonly seen on the ventilator display? correct answer: *pressure time(p-T) flow time ( F-T ) volume time ( V-T) In PC, we want to monitor tidal volumes, because they are variable and can change depending on Cl and Raw. correct answer: true A mode of mechanical ventilation which provides a form of IMV which incorporates a targeting scheme correct answer: auto mode According to the book, Vt range for non-ARDS patient is. correct answer: 6-8 ml/kg IBW
