Yes, you can do that, Sherri.
From the import dialogue, select the folder where the image you want to work on resides.
Lr will display thumbnails of the images within the folder, each with a tick at top left.
If you click the "Uncheck all" button at the bottom left of the screen, the ticks will be removed. You can then select the one image you want to work on, tick it, and select "Import" at bottom right.
It's not really how Lr is used to its best advantage, but it can be done.
