Residual urine refers to the amount of urine that remains in the bladder after urination. It is commonly assessed to evaluate the urinary system's function and can indicate certain health issues, particularly in the context of urinary obstruction or bladder dysfunction.

A maximum amount of residual urine considered abnormal typically exceeds 100 cc. Values above this threshold suggest that the bladder is not emptying sufficiently, which can lead to complications such as urinary tract infections or bladder distention. In clinical practice, residual volumes less than 100 cc are generally regarded as normal; therefore, any residual volume at or below this limit is often not viewed as a concern.

While the choices provided include 30 cc, 50 cc, and 70 cc, these amounts generally fall within a normal range and would be considered acceptable for residual urine. The 100 cc limit serves as a key marker indicating that further investigation may be warranted if a patient's residual urine exceeds this volume.
