This Concept Map, created with IHMC CmapTools, has information related to: Renal System Case Study, A 27-year-old man presents to the outpatient clinic complaining of 2 days of facial and hand swelling. He first noticed swelling around his eyes 2 days ago, along with difficulty putting on his wedding ring because of swollen fingers. Additionally, he noticed that his urine appears reddish-brown and that he has had less urine output over the last several days. He has no significant medical history, His only medication is ibuprofen that he took 2 weeks ago for fever and a sore throat. which have since resolved. On examination, he is afebrile, with heart rate 85 bpm and blood pressure 172/110 mm Hg. He has periorbital edema; his funduscopic examination is normal without arteriovenous nicking or papilledema. His chest is clear to auscultation, his heart rhythm is regular with a nondisplaced point of aximal impulse (PMI). and he has no abdominal masses or bruits. He does have edema of his feet, ands, and face. A dipstick urinalysis in the clinic shows specific gravity of 1.025 with 3+ blood and + protein. but it is otherwise negative. suggest What should be your clinical approach to this man?
