Central Venous Pressure Quiz

A patient presents with signs of fluid overload. Which CVP measurement would most likely confirm this diagnosis?

• 1 mmHg

• 4 mmHg

• 8 mmHg

• 12 mmHg

During a CVP measurement, the nurse notices the catheter is not zeroed at the phlebostatic axis. What is the most likely consequence?

• Inaccurate pressure measurements

• Increased risk of infection

• Incorrect medication delivery

• Difficulty in measuring heart rate

A patient with a CVP of 15 mmHg is being assessed. What condition might this indicate?

• Hypovolemia

• Hypervolemia

• Dehydration

• Normal heart function

Which anatomical landmark should the nurse use to zero the CVP catheter?

• Second intercostal space

• Fourth intercostal space

• Fifth intercostal space

• Midline of the sternum

A nurse is preparing to measure CVP using a central venous catheter. Which of the following is NOT a method for measuring CVP?

• Using a central venous catheter

• Using a pulmonary artery catheter

• Using a sphygmomanometer

• Transducing a pressure

If a patient has a CVP of 1 mmHg, what does that suggest about their fluid status?

• They are hypervolemic

• They are at risk for fluid overload

• They may be hypovolemic

• Their heart is functioning normally

Why is it essential for the catheter tip to be as close to the cavoatrial junction as possible during CVP measurement?

• To reduce the risk of infection

• To enhance the accuracy of measurements

• To make the procedure easier

• To ensure proper blood flow

A patient with suspected hypovolemia is being monitored. Which CVP reading would support this diagnosis?

• 0 mmHg

• 5 mmHg

• 10 mmHg

• 15 mmHg

Which veins are primarily involved in CVP measurements?

• Superior and inferior vena cava

• Left and right pulmonary veins

• Jugular and femoral veins

• Radial and ulnar veins

What is the normal range for CVP?

• 0 to 6 mmHg

• 4 to 8 mmHg

• 8 to 12 mmHg

• 12 to 16 mmHg
