A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding is the cause of immediate action by the nurse?
a. Blood pressure of 76/58 mm Hg
b. Sodium level of 138 mEq/L
c. Potassium level of 5.5 mEq/L
d. Pulse rate of 90 beats/min
ANS: A
Hypotension can be a problem with CVVH if replacement fluid does not provide enough volume to maintain blood pressure. The specially trained nurse needs to monitor for ongoing fluid and electrolyte replacement. The sodium level is normal and the potassium level is slightly elevated, which could be normal findings for someone with acute kidney injury. A pulse rate of 90 beats/min is normal.
