Analysis has shown that a client's right atrial pressure is 30 mm Hg. What is the most likely conclusion that the client's care team will draw from this piece of data?

A)
The result is likely normal and gravity dependent given the lack of valves in thoracic and central veins.
B)
The pressure is insufficient to provide adequate stroke volume and cardiac output.
C)
The pressure is excessive given that the right atrium should be at atmospheric pressure.
D)
Pressure pulsations are likely to be undetectable given the low atrial pressure.

Question 2

A physical assessment of a 28-year-old female patient indicates that her blood pressure in her legs is lower than that in her arms and that her brachial pulse is weaker in her left arm than in her right.

In addition, her femoral pulses are weak bilaterally. Which of the following possibilities would her care provider most likelysuspect?
A)
Pheochromocytoma
B)
Essential hypertension
C)
Coarctation of the aorta
D)
An adrenocortical disorder

Answer to Question 1

Ans:
C

Feedback:

Normal right atrial pressure is around 0 mm Hg, or atmospheric pressure. Right atrial pressure does not have a direct influence on stroke volume or pulse pressure.

Answer to Question 2

Ans:
C

Feedback:

The differences in blood pressure between the upper and lower extremities combined with weak femoral pulses and unilateral brachial pulse weakness are associated most strongly with coarctation of the aorta.
