Failure to Complete Ordered Daily Ammonia Laboratory Tests

Golden Sonora Care CenterSonora, California Survey Completed on 04-02-2026

Summary

The deficiency involves the facility’s failure to obtain ordered daily ammonia laboratory tests for one of four sampled residents. The resident was admitted in 2025 with hepatic encephalopathy, liver cirrhosis, and chronic kidney disease. An order dated 3/21/26 directed staff to check the resident’s ammonia levels every day shift and notify the physician if levels were about 65. Review of the medical record showed no ammonia lab results for 3/25/26, 3/28/26, and 3/31/26, despite the standing daily order. During interviews, the resident and a family member reported that the resident was upset because his ammonia levels were not being checked daily as ordered, and that his last ammonia blood draw had occurred when he went to the hospital, not at the facility. The resident stated that his ammonia level had been 93 and then decreased to 44 at the hospital, and that on 3/31/26 he returned from an outside appointment before lunchtime and believed the facility had time to draw his blood but did not do so. The family member expressed concern that the resident had to go to the hospital just to have his ammonia level checked. Nursing and management staff confirmed that the daily ammonia lab order had been in place since 3/21/26 and that the missing results for 3/25/26, 3/28/26, and 3/31/26 meant the order was not followed. Staff explained that facility nurses were responsible for drawing blood, that specimens were to be delivered promptly to the hospital laboratory, and that nurses were expected to monitor residents, document blood draws, follow up on results, and notify management and the physician if they were unable to obtain a specimen or results. The contracted laboratory confirmed that no ammonia specimens for the resident were received from the facility on the three missing dates and stated that any non-viable specimen would have prompted notification to the facility to obtain a new sample.

Short Summary

A resident with an abdominal surgical incision and left flank wound had a wound culture ordered after green drainage was noted from the wound vac, along with IV vancomycin and aztreonam. The culture was cancelled because the wrong tube was used, the wound was not re-cultured, and the wound nurse stated she had swabbed the fluid instead of the surgical site and believed the culture had already been completed.
