FILE - In this April 14, 2016, file photo, a son, at right, holds his mother's hand as they talk at her nursing home in Adrian, Mich. U.S. adults providing long-term care for elderly relatives have a shortage of medical training but plenty of commitment, according to a new poll. The Associated Press-NORC Center for Public Affairs Research survey found that nearly half of caregivers provide some medical care, from changing bandages (30 percent) to inserting catheters or feeding tubes (6 percent). But fewer than half got training to perform such delicate tasks. Still, more than 9 in 10 find the experience rewarding. (AP Photo/Carlos Osorio, File)
