Final answer:
The finding that indicates nonoliguria is D. Urinary output of 500 mL/day, as it meets the minimum volume required to maintain normal body function and proper elimination of metabolic wastes.
Step-by-step explanation:
The question is seeking to identify the urinary output that indicates nonoliguria. Oliguria is defined as a urinary output of less than 500 mL per day. It is often associated with several conditions including fever, shock, vomiting, and diarrhea. On the other hand, anuria refers to a virtually absent urinary production and is usually observed in acute renal failure or nephritis situations. Considering normal urine excretion ranges between 600 mL and 2500 mL per day, with a minimum required output of about 500 mL per day for the elimination of metabolic wastes, any finding above this minimum signifies nonoliguria. Thus, looking at the options given:
- A. 200 mL/day - indicates oliguria
- B. 300 mL/day - indicates oliguria
- C. 400 mL/day - indicates oliguria
- D. 500 mL/day - indicates nonoliguria, as it meets the minimum urine volume necessary to rid the body of wastes without impairment to organ function.
