A care home in Renfrew has been warned it faces closure unless it addresses "significant concerns" raised by inspectors about the quality of care.
The Care Inspectorate has told the operators they must make improvements by 15 December or risk having the home's registration cancelled.
Failings included medication management, monitoring residents' health needs, treatment of pressure sores and other wounds, management oversight and nutritional care.
Craigielea Care Home said it was taking the watchdog's report "very seriously" and was working to strengthen the quality and consistency of the care it provides.
The modern building in the town's French Street is registered to care for up to 85 residents, made up of 65 older residents and 20 adults with physical disabilities.
Craigielea is part of the Holmes Care Group which runs about 20 homes, almost all of them in Scotland.
A spokesperson for the Care Inspectorate said: "An inspection has identified significant concerns about the quality of care experienced by residents at Craigielea Care Home in Renfrew.
"We understand this is a difficult and distressing time for residents, their families and staff at the service.
"However, our first priority is always the health and wellbeing of people.
"Because of our concerns we have issued an improvement notice.
"This sets out the significant improvements that must be made within a specified timeframe."
Five areas of concern
Care homes in Scotland must be registered in order to operate legally.
In a letter to Holmes Care Group Scotland, the care watchdog gave notice that it would propose cancelling its registration for Craigielea unless significant improvements were made by 15 December in five areas:
Medication: Ensure residents receive the correct medicines safely, on time and with accurate record-keeping.
Healthcare monitoring: Improve assessment and monitoring of residents' health so changes in their condition are identified and acted on promptly.
Wound and pressure care: Make sure residents at risk of pressure sores or wounds receive appropriate assessments, treatment and preventative care.
Management and oversight: Strengthen auditing, governance and reporting systems to identify problems and ensure improvements are made.
Nutrition and hydration: Ensure residents' nutritional and hydration needs are properly assessed, monitored and met.
In a statement, a spokesperson for Craigielea Care Home said: "We take the Care Inspectorate's report very seriously and are already working closely with the Care Inspectorate and Renfrewshire Health and Social Care Partnership to strengthen the quality and consistency of the care we provide.
"Our management team remains available to support residents, family members and staff at this time, and a comprehensive improvement plan is in place, led by our regional operations manager and wider senior leadership team.
"Our priority is always the wellbeing of our residents, ensuring they receive safe, compassionate, and high-quality care in a setting where they feel valued and supported."
The Care Inspectorate said it would publish its most recent inspection report in due course. Previous reports in recent years have rated Craigielea as good or adequate.
