Does anybody know how we can tell if our loved one is approaching the "home stretch"? My father (in his 90's) has weakened so much, physically and mentally, and yet he still seems to have much spiritual strength. His fingernail beds have taken on a paler, milky bluish color, and he is having more trouble hearing and comprehending me when I speak to him. During these past several caregiving years, I have relied on my intuition to tell me what to do, and I will continue to follow my instincts, based on my love for Dad. The staff hasn't indicated to our family that time is running out, so I am still planning (in my mind) for long-term care. Has anyone else observed the type of fingernail bed color that I am describing?
