A 3-year-old female patient woke up this morning feeling agitated and with a fever of 103.4° F (39.7° C). She was crying yesterday and reported back pain. She has a history of asthma controlled by daily cetirizine and occasional albuterol. She has had two urinary tract infections (UTIs) in the past 4 months. Given the patient’s history and current condition, which condition is she most likely experiencing, what actions should the nurse take, and what parameters should the nurse monitor?
