Kettering TMC Modules Questions and Answers | Latest Version | 2024/2025 | Already Graded A A balloon-tipped catheter with the balloon deflated in the pulmonary artery measures which pressure at the proximal lumen? A) CVP B) PAP C) PWP D) MAP A. CVP When using a Swan-Ganz catheter for hemodynamic monitoring, the proximal lumen measures CVP. The distal lumen measures PAP when the balloon is deflated and PWP when the balloon is inflated. Which of the following conditions would NOT cause a capnography reading to decrease from 36 torr to 30 torr? A) Endotracheal tube in the right mainstem bronchus B) Hyperventilation C) Pulmonary emboli D) Hypovolemia A. Endotracheal tube in the right mainstem bronchus Positioning an endotracheal tube in the right mainstem bronchus usually results in an increase in end-tidal CO2 (PeTCO2) rather than a decrease. With these hemodynamic readings from an ICU patient: - 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 L/min/m2 What is the most likely condition? A) Right heart failure B) Left heart failure C) Pulmonary embolism D) Normal cardiac function C. Pulmonary embolism Increased CVP and mean PAP with normal PCWP suggest a pulmonary issue, not a left heart problem. Normal MAP, QT, and QI indicate that overall cardiac function is not severely impaired. Which factor does NOT affect the accuracy of a capnograph? A) Long sampling line B) Low sampling flow C) Condensation in the tubing D) Use of a desiccant D. Use of a desiccant A desiccant enhances accuracy by removing moisture from the gas sample. Long sampling lines, low sampling flows, and condensation can all interfere with accurate readings. For a stable 1000 g neonate in the NICU, which monitoring method is best for overall cardiopulmonary status? A) TcPCO2 and TcPO2 monitor B) Arterial blood gas analysis every 4 hours C) SpO2 monitor D) Capillary gas analysis every 8 hours
