A nurse at a long-term care facility is caring for older adult clients. Which of the following assessments should the nurse consider when monitoring clients for urinary retention?

A. Bladder distension: Palpation or percussion of the suprapubic area can reveal a firm, rounded mass indicating that the bladder is overfilled and unable to empty. This physical finding is a direct indicator of urinary retention in both acute and chronic settings. Bedside bladder scanning is often used to confirm the volume of retained urine. B. Voiding pattern: Frequent voiding of small amounts, such as 25 to 50 mL, suggests that the bladder is perpetually full and only the excess is leaking out. Monitoring the frequency and volume of micturition helps differentiate between normal voiding and "retention with overflow." Changes in the established pattern are critical indicators of deteriorating bladder function. C. Color of the urine: The hue of the urine generally reflects hydration status or the presence of blood and bilirubin rather than the ability to empty the bladder. While dark urine may indicate concentration, it does not confirm the mechanical presence of residual volume. Retention is a matter of volume and pressure rather than pigment. D. Proteinuria: The presence of protein in the urine is a marker of glomerular damage or systemic disease rather than a sign of retention. Proteinuria is typically identified through urinalysis and does not correlate with the bladder's ability to contract. Assessment of retention must focus on mechanical emptying rather than the filtration of proteins. E. Dribbling of urine: Involuntary leakage or constant dribbling often occurs when the intravesical pressure exceeds the urethral resistance in a distended bladder. This "overflow" is a classic clinical manifestation of chronic urinary retention where the bladder never fully empties. Dribbling should prompt a focused assessment for post-void residual volume.
