A patient is receiving a rapid infusion of hypertonic sodium chloride solution. To guard against too much fluid being infused too rapidly, a nurse frequently assesses the patient for which of the following findings?
a. Increased urine output
b. Serum potassium level of 4 mEq/L
c. Crackles in the lungs upon auscultation
d. Serum sodium level of 126 mg/dL
C
Too rapid an infusion or too much volume with a hypertonic solution can lead to fluid overload, which manifests as crackles in the lungs, a symptom of pulmonary edema.
Increased urine output is expected with an increase in fluid volume, therefore this would not be an abnormal finding.
A patient receiving a hypertonic IV solution is at risk for hypernatremia and thus hypokalemia. This patient's potassium level is normal.
A serum sodium level of 126 mg/dL indicates hyponatremia, which would not be assessed in a patient receiving a hypertonic solution IV.
