What assessment should the nurse make before initiating an intravenous (IV) infusion of dextrose 5% in 0.9% normal saline solution with 10 mEq of potassium chloride for a child hospitalized with dehydration?
a. Fluid intake
b. Number of stools
c. Urine output
d. Capillary refill
C
Potassium chloride should never be added to an IV solution in the presence of oliguria or anuria (urine output less than 0.5 mL/kg/hr). Fluid intake does not provide information about renal function. Stool count sheds light on intestinal function. Renal function is the concern before potassium chloride is added to an IV solution. Assessment of capillary refill does not provide data about renal function.
