Which of the following should be reported to the nurse regarding urine output?

The correct answer encompasses all listed options because they each represent significant changes or concerns regarding urine output that warrant immediate attention from a nurse.

Urine output that is less than 30 ml per hour indicates potential kidney issues or dehydration and requires medical evaluation to prevent complications. Cloudy, bloody, or dark tea-colored urine can suggest infections, blood in the urine, or other serious health concerns that need to be assessed promptly. Additionally, an inability to void may signal a blockage, retention issues, or other serious conditions that could jeopardize the patient's health.

Each of these signs can indicate underlying medical issues that need further investigation or intervention, which is why they must be reported to a nurse. By reporting all of these conditions, healthcare providers ensure that appropriate care measures can be taken to address the patient's needs.
