Question

How is CVP measured in hospitalized cardiac/critical care patients?

A) Through arterial blood gases
B) Through pulmonary artery catheterization
C) Through electrocardiogram (ECG) monitoring
D) Through fingerstick glucose monitoring

Answer 1

CVP is measured in hospitalized cardiac/critical care patients through pulmonary artery catheterization.

Step-by-step explanation:

CVP (central venous pressure) is measured in hospitalized cardiac/critical care patients through pulmonary artery catheterization (option B). This involves threading a thin tube, called a catheter, into the appropriate location to transmit pressures to external measuring devices. It is an invasive procedure that allows healthcare workers to monitor blood pressure in the major veins, heart chambers, and arteries to the brain and lungs. Arterial blood gases (option A) are used to assess oxygen and carbon dioxide levels, not CVP. Electrocardiogram (ECG) monitoring (option C) is used to assess heart rhythms, not CVP. Fingerstick glucose monitoring (option D) is used to measure blood glucose levels, not CVP.
