Elimination, Ostomy Care & Intake/Output

Monitoring and Reporting Body Fluids

PCTs routinely observe and document the color, consistency, odor, and amount of urine, stool, and emesis, reporting abnormal findings to the nurse promptly rather than waiting to see if they resolve.

Any of these abnormal findings, along with a sudden change in frequency, associated pain, or a change in the patient's overall condition, must be reported right away. A PCT's careful observation is frequently the first clue to a serious complication such as gastrointestinal bleeding or urinary obstruction.

Ostomy Care

An ostomy is a surgically created opening, called a stoma, that connects an internal organ, either the bowel (colostomy or ileostomy) or the bladder (urostomy), to the abdominal surface for waste to drain into an external pouch. PCT responsibilities generally include emptying and changing the ostomy pouch or appliance, measuring and recording output, and assessing the stoma and the surrounding skin. A healthy stoma is red or pink and moist, similar in appearance to the inside of the cheek. The PCT should report a stoma that appears pale, dusky, purple or black, dry, or actively bleeding, as well as any skin breakdown around the base of the stoma.

A critical scope limit that is frequently tested: the PCT does NOT irrigate an ostomy. Irrigation, which involves instilling fluid into the stoma to regulate bowel emptying, is a task reserved for the nurse or a specially trained and certified individual, and it falls outside the PCT's scope of practice regardless of how routine the task may appear.

Intake and Output (I&O) Measurement

Accurate I&O tracking helps the care team monitor fluid balance, kidney function, and hydration status. All intake and output must be measured and recorded in milliliters (mL), never estimated using vague terms such as a lot or a little:

• Intake includes all oral fluids, ice chips (counted at roughly half their volume once melted), IV fluids, and tube feedings.
• Output includes urine, emesis, liquid stool, wound drainage, and suction or drain output.
• Use a calibrated graduated container, often called a hat or a urinal, to measure urine, and record the amount immediately after each void or emptying rather than relying on memory later in the shift.
• Standard conversions used in I&O documentation: 1 ounce equals about 30 mL, and an 8-ounce cup equals about 240 mL.

Normal Urine Output

A key benchmark the PCT should know cold: adequate adult urine output is generally accepted as a minimum of about 30 mL per hour, roughly 0.5 mL per kilogram per hour for an average adult. Output persistently below this minimum, or a marked drop from the patient's normal pattern, should be reported promptly, since it can signal dehydration, urinary retention, a blocked catheter, or kidney dysfunction. Conversely, an absence of urine output for several hours, especially in a catheterized patient, also warrants immediate reporting, since it may indicate a kinked or occluded catheter rather than true kidney failure.

Foley Catheter and Bladder Considerations

Many patients whose intake and output are being tracked closely also have an indwelling urinary (Foley) catheter, and the PCT plays a role in monitoring the closed drainage system even though catheter insertion itself is a nursing task. Keep the drainage bag below the level of the bladder at all times to prevent backflow of urine, which can introduce infection; keep the tubing free of kinks and dependent loops that could trap urine and produce a falsely low output reading; and never let the drainage bag or tubing touch the floor. Empty the bag into a calibrated container at the end of the shift or per facility schedule, recording the exact volume, color, and clarity, and report a sudden absence of drainage, cloudy or foul-smelling urine, or blood in the tubing right away, since these can indicate a blocked catheter, infection, or bleeding rather than a genuine change in kidney function.

Putting It Together

Because elimination monitoring, ostomy care, and I&O tracking are all fundamentally about early detection of complications, the PCT's role centers on accurate measurement, careful observation, and prompt reporting rather than on making treatment decisions. When a PCT is uncertain whether a finding is abnormal, the safest and correct action is always to report it to the nurse rather than wait to see whether it resolves on its own. Consistent, honest documentation, recording exactly what was measured or directly observed rather than an approximation, is what allows the rest of the care team to catch a developing problem early and intervene before dehydration, urinary retention, or an infection becomes a more serious complication requiring escalation.
