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.

Delay in Venous Ultrasound for Symptomatic Resident

F0770 F770: Provide timely, quality laboratory services/tests to meet the needs of residents.
Short Summary

A resident with a history of fractures and chronic diastolic HF developed new swelling, hardness, and warmth in the right arm and hand after cast removal. Nursing staff documented the change and a venous ultrasound of the upper extremity was ordered, but despite follow-up with a mobile radiology vendor, the doppler study was not performed as expected. Several days later, the ultrasound was completed and showed an occlusive radial DVT. Staff interviews and job descriptions confirmed that CNAs, LPNs, and RNs were expected to promptly report changes in condition, notify physicians, and follow up with outside vendors the same shift when ordered tests were not completed, yet there was an unexplained delay in obtaining the ordered diagnostic test.

Short Summary

Failure to Complete Ordered Lab Monitoring: A resident with a stage 4 pressure ulcer, vitamin D deficiency, diabetes, kidney disease, and dementia did not have ordered Albumin and Pre-Albumin labs completed on schedule, and ordered yearly Vitamin D and lipid panel testing was not documented as obtained. The physician expected labs to be done as ordered, while the LVN, DON, and Administrator each stated labs were supposed to be tracked and completed through the facility’s routine process, but the DON was unaware the resident was missing labs until surveyor intervention.

Failure to Obtain Ordered Urinalysis After Resident Fall
D
F0770 F770: Provide timely, quality laboratory services/tests to meet the needs of residents.
Short Summary

A resident with a history of falls, hemiparesis after stroke, type II diabetes, urinary incontinence, and severe cognitive impairment experienced a fall and had a care plan intervention for labs and a UA to be collected afterward. An LVN documented that an NP ordered both a CBC and UA as part of the post-fall evaluation, but only the CBC was coordinated and completed; no UA order appeared in the physician’s orders, and no UA was obtained. In interviews, the NP stated it would be reasonable for her to order a CBC and UA to assess for infection and possible cause of falls, while the LVN stated she believed the NP only ordered a CBC and that the UA would be contingent on UTI symptoms. The DON and Administrator stated that nurses are expected to implement prescribers’ orders and that the LVN was responsible for coordinating the UA but did not, potentially denying prescribers needed lab information.

Failure to Timely Review and Communicate Critical and STAT Lab Results
D
F0770 F770: Provide timely, quality laboratory services/tests to meet the needs of residents.
Short Summary

The facility failed to ensure timely review and communication of critical and STAT PT/INR lab results for two residents on anticoagulation therapy. In one case, a resident’s critically high PT/INR result was available in the lab system and fax attempts failed, but nursing staff did not review the result until the next day and the MD was not notified when the result became available. In another case, a STAT PT/INR result was not phoned to the facility by the contracted lab, and nursing staff did not check the lab system and review the result until nearly a full day later. Leadership acknowledged that critical and STAT labs are expected to be called by the lab and that nurses are also expected to monitor the electronic lab system, but these processes did not occur as required.

Failure to Obtain Ordered Urine Culture and Sensitivity Test
D

Short Summary

A resident with a history of UTI reported dysuria, and the physician ordered a UA flex to culture and later prescribed Macrobid pending urine C&S results. Facility policy required timely laboratory services and specified that the day shift nurse complete and send lab requests. Although the UA was completed and results communicated to the physician, review of lab records showed no urine C&S was ever performed. The NHA confirmed that the lab order was transcribed incorrectly, so the C&S test was not completed as ordered.

Failure to Monitor Anticoagulation Lab Results Leading to Supratherapeutic INR
D

Short Summary

A resident receiving anticoagulation therapy for an upper extremity thrombosis had multiple physician orders for INR testing, and blood was reportedly drawn, but PT/INR tests were not completed and no lab results were documented for several ordered test dates. The DON acknowledged that although lab orders were placed correctly, the anticoagulation testing was not performed, and the physician reported frequently ordering INRs without receiving any results. The resident was later hospitalized with a supratherapeutic INR of 12.0 and a markedly prolonged PT, while the facility was unable to provide a relevant policy during the survey.
