Final answer:
Report the low urine output of 50 cc from Mrs McQueen's catheter bag to the nurse in charge or follow facility documentation protocols, as it may indicate a health issue.
Step-by-step explanation:
If you are emptying catheter bags at the end of your shift and notice that Mrs McQueen's catheter bag only has 50 cc in it, you should report this finding to the nurse in charge or document it according to your facility's protocol. A notably low urine output may be an indication of dehydration, renal issues, or other medical concerns that should be monitored closely. It is important to ensure accurate recording of urine output for patient health monitoring.
