A care worker has been jailed for ill-treating two elderly patients at a Leicestershire residential home.
Dawn Heaney, 38, slapped a woman at Wymeswold Court, near Loughborough.
Leicester Crown Court was also told she gave an 85-year-old Alzheimer's sufferer tea containing vinegar and insulted other residents.
The judge said the nine-month term sent a message that those who care for the weak, the elderly and the otherwise vulnerable must not abuse them.
The incidents happened between August 2009 and March last year.
Heaney, of Main Street, Woodthorpe, Loughborough, was suspended from her job in March 2010 after concerns were raised to managers at the home, her trial in July heard.
The court was told how Heaney slapped the back of the head of the 93-year-old woman, who uses a wheelchair, and verbally insulted others.
Heaney was cleared of three other counts of ill-treatment of patients.
