She moved to the United States 16 years ago and says she plans to continue climbing, while keeping her job in the supermarket.
Kami Rita first climbed Everest as a 24-year-old in 1994.
Before leaving for the mountain last month, Kami Rita told The Associated Press that he wanted to scale Everest at least 25 times.
Most hopefuls are escorted by a Nepali guide, meaning about 700 climbers will tread the same path to the top of the 8,850-metre (29,035-foot) peak in the coming weeks. He has also climbed numerous region's other high peaks, including K-2, Cho-Oyu, Manaslu and Lhotse.
A Sherpa guide has been missing on Everest's southern side in Nepal since Monday, said Mingma of Seven Summits.
The other two previous summit record-holders are also Sherpas.
"I did not start climbing to set a world record", he told AFP last month before setting out for the mountain. Phurba Tashi, 47, retired from high-altitude climbing in 2013 but still works at Everest's Base Camp helping organise expeditions. She now lives in the USA and works at a departmental store.
The route to the top of Mt. Everest was opened Sunday when eight rope-fixing Sherpas stood atop the mountain.
According to alpinist and mountain chronicler Alan Arnette, who year is following the events on the highest mountain on in the world this year for the USA magazine Outside Online, at an altitude of 8500 meters 10 of the 39 regulators used by clients and Sherpa suddenly stopped working.
Ethnic Sherpas, renowned for their endurance and experience at high altitudes, serve as guides for many foreign mountaineers attempting to climb the highest Himalayan peaks.
