Lennon said she will be expected to shower, toilet and attend her mother's every need without backup.
"I understand doctors will be doing medication round but that's about it."
With less than 24 hours notice Lennon said she has been given no option but to urgently leave her work and drive down to Thames tonight so she can be at the hospital by 7am tomorrow.
She has been offered a Lazyboy to sleep on while the strikes go through the night.
A Waikato District Health Board spokesperson confirmed families were being asked to care for their loved ones while nurses were on strike but they would not be expected to travel from another city.
"We don't really have a choice. Our priority is life-threatening patients," the WDHB spokesperson said.
Lennon said she worried about the safety of the patients.
The WDHB spokesperson said at the moment there were 20 inpatients at Thames Hospital and two nurses will be on duty during the strikes.
"I can assure they will be cared for."
