A 4-year-old child presents for a well-child visit. The parents report the child is doing well, has a good appetite, and has been meeting developmental milestones appropriately. Two months ago, the child was treated with antibiotics for an upper respiratory tract infection. Otherwise, the child is quite healthy. Upon assessment, the nurse notes a left-sided flank mass. The child denies urinary issues including pain or frequency, and the parents report that the child has had no incontinence episodes for a full year. The urinalysis is normal with the exception of 2+ blood. The nurse prepares to educate the family on which condition that most likely explains the child’s symptoms?

The unconscious patient with elevated intracranial pressure secondary to an ischemic stroke has a jugular bulb catheter in place to monitor cerebral oxygenation (SJO₂). The patient’s oxygen saturation (read by peripheral pulse oximetry probe) is 98% on 30% FiO₂ administered via endotracheal tube. The SJO₂ is 85%. How does the nurse interpret these results?
