OTOH, she might have been EurAsian.
Barbara Eden had those uptilted eyes, too.
I was deployed to Uzbekistan & the local gals had those eyes, round and very non-east Asian. When I saw this episode after I got back, that actress now looked Central Asian to me.
That episode was one of the early videotapes, which added to the spookiness of the hospital corridor scene. Years ago I was in the basement floor of an Army hospital & suddenly saw a sign that read “MORTUARY”. Thought of that night nurse & headed up the stairs.
