Final answer:
The characteristics of urine expected in a patient with oliguria would be a dark yellow color and high specific gravity due to the concentration of solutes in the reduced volume of urine. The correct option is A.
Step-by-step explanation:
The expected characteristics of urine from a patient with oliguria, which is the production of abnormally small amounts of urine, would likely include a dark yellow color and a high specific gravity.
This is because the reduced volume of urine is typically more concentrated, containing a higher amount of solutes per unit than normal. The correct answer to the question is a. Dark yellow color, high specific gravity. Other conditions, such as dehydration, can also cause urine to appear darker due to its concentrated nature.
