Kettering TMC Modules Test Questions with Guaranteed Accurate Answers

A balloon-tipped, flow-directed catheter is positioned in the pulmonary artery with the balloon deflated. Which of the following pressures will be measured by the proximal lumen? A) CVP B) PAP C) PWP D) MAP - correct answer A. CVP Swans gans catheter for hemodynamic monitoring. Distal deflated is PAP, Distal inflated is PWP All of the following could cause a capnography reading to change from 36 torr to 30 torr EXCEPT A) endotracheal tube positioned in the right mainstem bronchus B) hyperventilation C) pulmonary emboli D) hypovolemia - correct answer A. endotracheal tube positioned in the right mainstem bronchus. This will cause PeTCO to increase A patient in the intensive care unit has the following hemodynamic measurements: CVP: 9 mmHg Mean PAP: 24 mmHg PCWP: 9 mmHg MAP 93 mmHg Cardiac Output (QT): 5.4 L/min Cardiac index (QI): 2.9 Lmin/m2 A) right heart failure B) left heart failure C) pulmonary embolism D) normal cardiac fuction - correct answer C. pulmonary embolism CVP-High, Mean PAP-High(lungs), PCWP-Normal (rules out left heart problem), MAP-normal, QT-normal, QI-normal All of the following will affect the accuracy of a capnograph EXCEPT A) long sampling line B) low sampling flow C) condensation in the tubing D) use of a desiccant - correct answer D. use of a desiccant-chemical that removes moisture from the gas creating a more accurate measurement Long sampling line will take longer for gas to pass thru to reach analyzer, low sampling flow wont give enough info for good reading, condensation in the tubing can cause obstruction in line A 1000 g neonate is stable in the NICU. Which of the following should the respiratory therapist use to monitor the neonate's overall cardiopulmonary status? A) TcP
