A client comes into the emergency department (ED) by ambulance after slipping on a small carpet in his home. The client fell on his hip with a resultant fracture. He is alert and oriented; his pupils are equal and reactive to light and accommodation. His heart rate is elevated, he is anxious and thirsty, a Foley catheter is placed, and 40 mL of urine is present. What is the nurse's most likely explanation for the low urine output? The man is experiencing symptoms of heart failure and is releasing atrial natriuretic peptide that results in decreased urine output. The man is having a sympathetic reaction, which has stimulated the renin-angiotensin-aldosterone system that results in diminished urine output. The man urinated prior to his arrival to the ED and will probably not need to have the Foley catheter kept in place. The man likely has a traumatic brain injury, lacks antidiuretic hormone (ADH), and needs vasopressin.
