Understanding Urinary Retention Levels

A nurse is assessing a patient who is experiencing difficulty in urination. Upon further examination, the nurse finds that the patient has not voided for over 12 hours. The nurse determines that this situation may lead to potential complications, including urinary retention.

To quantify urinary retention, the nurse plans to measure the patient's bladder volume using a bladder scan after palpation. Should the bladder scan indicate a volume exceeding ___ mL, the nurse will notify the healthcare provider for further intervention.
