    I don't know, everything I read says if NA+ decreases so does atrial pressure.

    Yes this is one of our study guide questions and all I can find is the same thing you said when NA decreases so does atrial pressure.

    It depends on what is causing the hyponatremia.

    If the patient has SIADH, or where the low sodium is caused by fluid overload, the atrial pressure will be increased.

    However if the low sodium is related to vomiting and/or diarrhea the atrial pressure would be decreased.

    Wouldn't it be nice if things were clear cut in nursing???
