A patient is receiving slow continuous ultrafiltration to treat an acute kidney injury. Which of the following will the nurse need to continue to assess in this patient?
1. urine output
2. appetite
3. white blood cell count
4. electrolyte levels
4
Rationale: Slow continuous ultrafiltration is a method of continuous renal replacement that uses both arterial and venous access and, using the patient's blood pressure, circulates blood through the hemofilter. The goal of this therapy is to remove fluid only, and the patient does not receive any replacement fluid. Toxins are not removed with this treatment and urea levels and electrolytes are not corrected. The nurse will need to continue to assess this patient's electrolyte levels. The patient is experiencing acute renal failure and may or may not have a urine output. Assessment of appetite and white blood cell count also may or may not be indicated for this patient.
