Which client finding should the practical nurse (PN) report to the registered nurse (RN) immediately?

A. Coffee-ground secretions draining via nasogastric tube suction: Coffee-ground emesis indicates the presence of partially digested blood, suggesting gastrointestinal bleeding. This is a potentially life-threatening condition that requires immediate reporting and prompt intervention. B. Oral ice chips 30 minutes eaten after vomiting postoperatively: Offering ice chips shortly after vomiting is generally safe and may help prevent dehydration. While the PN should monitor for further vomiting, this finding does not require immediate reporting. C. Inability to void 4 hours after discontinuing an indwelling catheter: Postoperative urinary retention is important to monitor, but a 4-hour delay in voiding is often within acceptable limits and can be managed with assessment and interventions. D. Ineffective pain management reported while using morphine PCA: Ineffective pain control should be addressed promptly, but it is not immediately life-threatening. The RN can evaluate dosage adjustments or interventions without urgent escalation unless the client exhibits signs of severe distress or complications.
