While in the ICU, a client's status changes
The health care providers suspect heart failure. Which of the following diagnostic procedures would give the staff information about pulmonary capillary pressures, which will lead to the most appropriate interventions?
A) Echocardiography
B) Radionuclide ventriculography
C) Cardiac magnetic resonance imaging
D) Hemodynamic monitoring
Ans: D
Feedback:
Invasive hemodynamic monitoring may be used for assessment in acute, life-threatening episodes of heart failure. These monitoring methods include central venous pressure (CVP), pulmonary artery pressure monitoring, measurements of cardiac output, and intra-arterial measurements of blood pressure. Echocardiography plays a key role in assessing ejection fraction, right and left ventricular wall, wall thickness, ventricular chamber size, valve function, heart defects, and pericardial disease. Radionuclide ventriculography is recommended if there is reason to suspect coronary artery disease or ischemia as the underlying cause for heart failure. Cardiac magnetic resonance imaging and cardiac computed tomography are used to document ejection fraction, ventricular preload, and regional wall motion.
