Which statement by a patient's mother indicates a need for the nurse to check for signs of infiltration?

The statement indicating that the baby's fingers are looking swollen is a crucial observation that can suggest infiltration at the IV site. Infiltration occurs when IV fluids or medications inadvertently enter the surrounding tissue instead of the intended vein. Swelling in the fingers may be an early sign of this complication, as it can indicate fluid accumulation outside the vascular space.

Recognizing physical signs of infiltration allows for timely intervention, such as discontinuing the IV and assessing the site, which can prevent further complications. Other symptoms, while still important, may not be directly related to the localization of fluid around an IV site. For instance, increased sleepiness, unusual crying, or fever can indicate various other medical issues that do not necessarily point to infiltration. Therefore, observing localized swelling around the IV site is critical for the nurse to monitor closely for potential infiltration issues and ensure the safety and comfort of the patient.
