Hemodynamic monitoring Exam Solved 100% (verified)

Hemodynamic monitoring Exam Solved 100% (verified) The clinician is caring for an infant that has just returned from the catheterization lab where he had a radio-frequency (RF) procedure to open up his pulmonary valve. He is now noted to have an increased CVP. What is the most probable explanation for the infant's increased CVP? 1. Hypovolemia 2. Left ventricular dysfunction 3. Pulmonary valve regurgitation 4. Venous thrombosis - Answer- 3 is correct Which of the following statements is false in regards to the importance of invasive hemodynamic monitoring systems to patient outcomes? 1. Allows the clinician to immediately assess patient response to medications and other interventions. 2. Informs the clinician exactly what is happening within the heart. 3. Provides critical information about blood volume and fluid balance. - Answer- 2 is correct During the contracting phase of the cardiac cycle: 1. The atria fill with blood as it returns from the systemic circulation. 2. The mitral and tricuspid valves are open and the pulmonary and aortic valves are closed. 3. The ventricles force blood to flow through the pulmonary arteries and the aorta. 4. None of the above. - Answer- 3 is correct One advantage of invasive hemodynamic monitoring in critically ill children is: 1. Allows the clinician to spend more time with the sick child. 2. Allows visualization of the interior heart chambers for improved assessment of cardiac function. 3. Provides continuous monitoring of blood pressure and heart rate and provides immediate access for blood sampling. 4. Replaces the need for manual measurement of vital signs. - Answer- 3 is correct In hemodynamic monitoring, an overdamped waveform is one that: 1. Indicates fluid overload. 2. Lacks characteristic peaks and valleys. 3. Overemphasizes typical peaks and valleys. 4. Reflects the baseline waveform. - Answer- 2 is correct The correct location for measuring cardiac pressures and for zeroing the transducer system is the: 1. Atmospheric pressure. 2. Calibration flowpoint. 3. Cardiac notch. 4. Phlebostatic axis. - Answer- 4 is correct The amount of blood that is ejected into the aorta with each contraction of the heart is known as the: 1. Cardiac output. 2. Right ventricular pressure. 3. Stroke volume. 4. Systolic pressure. - Answer- 3 is correct The total amount of blood that is ejected by the heart in one minute is known as the: 1. Cardiac cycle. 2. Cardiac output. 3. End diastolic pressure. 4. End systolic volume. - Answer- 2 is correct The central venous pressure catheter measures the: 1. Pulmonary artery pressure and left heart function. 2. Pulmonary artery pressure and right heart function. 3. Right atrial pressure and left heart function. 4. Right atrial pressure and right heart function. - Answer- 4 is correct Troubleshooting the dampened waveform of a intra-arterial catheter should include assessment of all of the following except: 1. Assessment for loose connections or air bubbles within the system. 2. Assessment of the patient's condition and current vital signs. 3. Balloon inflation of the pulmonary artery catheter. 4. Examination for excess tubing length or use of compliant tubing. - Answer- 3 is correct
