My wife appeared to have passed out temporarily while eating. I found her lying against a file cabinet. She was not completely out but she was unable to sit up in her desk chair in front of the computer desk. I asked what happen and she asked me to pull her up and I did. I thought she might be dehydrated so I got her some water and a towel to wipe the sweat from her face. She is now up and walking around after drinking some of the water. I checked her blood pressure and it was normal(118/72). Her pulse rate was 69. She says she is okay. What should I be on the watch for? What should I advise her to do?
