Final answer:
The nurse practitioner will likely explain that the 3-year-old has grade I vesicoureteral reflux without ureteral dilation, usually managed with close monitoring and possibly preventative antibiotics, with a good chance of resolution as the child grows.
Step-by-step explanation:
The nurse practitioner is likely to inform the patient's father that their child has grade I vesicoureteral reflux (VUR), which is characterized by the reflux of urine into the ureter and collecting system without causing dilation. This condition can increase the risk of urinary tract infections (UTIs). Treatment options may vary; in mild cases like this where there is no ureteral dilation, the plan might include close monitoring, prophylactic antibiotics to prevent UTIs, and possibly recommendations for ensuring regular bladder emptying to mitigate the risk of infection.
Further, as the child grows, VUR can sometimes resolve on its own without surgical intervention. It’s essential that the father understands the importance of follow-up examinations to monitor their child's condition over time and to identify any changes that might require additional intervention.
