Can a permanent resident be denied entry to the US if she stays 7 months out of the US?

Yes, a permanent resident can be denied entry to the U.S. if they stay outside the country for an extended period, such as seven months. This duration may raise questions about their intent to maintain permanent residency. U.S. Customs and Border Protection (CBP) may consider the length of absence and the reason for it, potentially leading to a determination that the individual has abandoned their permanent resident status. It's advisable for permanent residents to consult with an Immigration attorney before extended travel abroad.
