Decreased central venous pressure (cvp)-rationale: assessment findings in a client with a deficient fluid volume include increased respirations and heart rate, decreased central venous pressure (cvp), weight loss, poor skin turgor, dry mucous membranes, decreased urine volume, increased specific gravity of the urine, increased hematocrit, and altered level of consciousness. the normal cvp is between 4 and 11 cm h2o. a client with dehydration has a low cvp. the assessment findings in options a, b, and c are seen in a client with excess fluid volume.test-taking strategy: use the process of elimination and focus on the subject, deficient fluid volume. eliminate options a and c first. lung congestion is noted in excess fluid volume, as is increased blood pressure. from the remaining options, recall that central venous pressure reflects the pressure under which blood is returned to the superior vena cava and right atrium. therefore, pressure (volume) would be decreased in a deficient fluid volume. if you had difficulty with this question, review the assessment findings noted in deficient fluid volume.
