The nurse is aware that in both the very young and the older adult surgical patient, the risk is much higher for:

A. Vanilla pudding: Vanilla pudding is not considered a clear liquid. It is a semi-solid food and should be removed from the tray as it does not meet the criteria for a clear liquid diet, which consists of liquids that are transparent and liquid at room temperature.

B. Beef broth: Beef broth is appropriate for a clear liquid diet as it is a transparent liquid and is allowed as part of the diet.

C. Orange gelatin: Orange gelatin is a common item on a clear liquid diet as it is transparent and can melt into a liquid form at room temperature. It is appropriate to leave it on the tray.

D. Cranberry juice: Cranberry juice is allowed on a clear liquid diet. It is a transparent liquid, so it should not be removed.

A. Urinary tract infections are common at this stage. While urinary tract infections (UTIs) are a potential postoperative complication, monitoring urine output is not primarily for detecting UTIs but for ensuring adequate kidney function and overall circulatory health.

B. Decreased urine output may be a sign of shock. Decreased urine output can be a key indicator of shock, as inadequate perfusion to the kidneys during shock reduces urine production. This is a critical sign of potential hemodynamic instability and warrants immediate attention.

C. A distended bladder is uncomfortable. While a distended bladder can be uncomfortable, monitoring urine output is more about assessing kidney function and detecting issues like dehydration, shock, or kidney failure rather than simply comfort.

D. Swelling may block the ureters or urethra. Swelling may cause urinary retention, but this is less common as a primary concern postoperatively. The primary reason for monitoring urine output is to assess overall circulation and kidney function, not necessarily to monitor for obstruction.
