In the next couple days I am going to take readings from my beer to see if it has stopped fermenting. However, I feel like each time I take a reading I will be pulling out a decent amount of my beer. My question is, can I put that beer back in the batch after I test it, or has it been too exposed to airborne microbes to be sanitary? I am going to sanitize the beaker, the beer thief, and the hydrometer but I am still worried that the exposure to the airborne microbes will contaminate it and I don't want to contaminate my whole batch. Any thoughts?

I don't put it back. I usually drink it.

Drink if you want, I take 1 oz samples for a refractometer so i do drink it (or coat the palate for taste)

If as you say everything is sanitized you can pour it back in. Most people do this when they dont have a large enough batch to keep pulling from or its such a high ABV that you dont wanna taste it so "green" risking less of a finished volume.
Avoid aeration if pouring back when pulling samples later into fermentation

+ 1 to drinking it. It wouldn't have occurred to me to even ask the question.

Drink it, I do.
A hydrometer sample runs about 3 oz. and you'll do 3 maybe 4 samples by the time you are ready to bottle. That adds up to about 1 12 oz beer.
You still have enough left in that 5 gallon batch (if you are making 5 gallon batches) for more than 2 cases of beer.
