Which information is essential for the nurse to keep in mind when monitoring a patient's central venous pressure?
1. It is better to look at current numbers for central venous pressure monitoring rather than trends.
2. Central venous pressure is a direct measurement of systemic vascular resistance.
3. A decreasing trend in central venous pressure may indicate right heart failure.
4. An increasing trend in central venous pressure may result from fluid building in the lungs.
4
Rationale 1: It is more accurate to look at trends than at one CVP reading.
Rationale 2: CVP is not a direct measurement of systemic vascular resistance.
Rationale 3: Right heart failure would cause an increasing CVP.
Rationale 4: As pressure in the lungs increases, volume in the right heart will increase, which will increase the CVP.
