Home health aides provide personalized care to the elderly and the disabled in
the patient’s own home. They help their patients take medicine,
eat, dress, and bathe. Home health aides need to have a
good number sense. They must accurately take the
patient’s temperature, pulse, and blood pressure, and
monitor the patient’s calorie intake and sleeping schedule.
