When Comparing Arterial, Central Venous, and Pulmonary Arterial Pressures, the Nurse

When comparing arterial, central venous, and pulmonary arterial pressures, the nurse keeps which factor in mind?

A) It is not a good idea to measure the patient's blood pressure from the arterial waveform tracing.
B) The pressures in the superior and inferior vena cava are lower than the pressure in the right atrium of the heart.
C) The normal pressure in the right atrium of the heart is very low, 4 to 6 mmHg.
D) The small vessels of the pulmonary arteries are under more pressure than systemic arterial blood pressure.
