I have been given a nearly new 16GB micro SD card (plus adaptor).
Is there any reason why I should not use this in the second slot of my D7200? Or should I only use a full size one?

They work. On the plus side, if you remove just the micro card, you won't be putting any wear on the camera contacts. I don't think wear on the camera contacts is a big concern, though.

I'm not one sure what a full size is. I use 2 32GB and have yet to fill one.

You can't do that easily, unless you have very strong fingernails😝.

A full size card is a standard SD card. The OP has a micro SD card with adapter, allowing it to work the same way a full size card works.

Your right, missed the micro.

Don't you have to take the adapter out of the camera to remove the micro from the adapter?

The micro card fits in the adapter; it then looks/acts like a regular size card.

But it was mentioned that using the micro would not put wear on the camera contacts. That I questioned.

Just re-read your question.
Yeah, youre right, you can't remove JUST the micro card. Card and adapter work and travel as a unit, same as a "full size, 1 piece" card.
Now I forget what was the point of the original question.
Moving on. 😈

it should work. I don't know if the failure rate differs between micro SD cards and full SD cards if they are removed often. I've never had a micro SD card fail in other devices like my phones and car GPS, but then they are not removed on a regular basis.

No reason why it would. You don't need to remove the card from the adapter, so it's only the adapter which gets any wear.

For me, it depends on what your comfort level is with the card. Personally, my policy is to NOT introduce an additional adapter (the sd to micro-sd adapter) to the equasion. Also, I try to keep all of my cards at the same read/write rate. I've found some extremely good deals on SD Cards that turned out to be lousy deals because the cards were so slow that I clogged the buffer with shots waiting to be written to the card.
I have a Nikon D7000, D7100 and a D610 that get used regularly. I have Sandisk 64gb cards in the D610 and D7100 and Sandisk 32gb cards in the D7000. All of my "backup" cards are Sandisk 32gb cards (I have 6 backups). The reason for the high number of cards is that I originally was using 16gb cards in the D7000 and D7100 and began to replace/upgrade to 32gb. Then I got the D610 and got a couple of 64gb cards, and now I am slowly replacing the 32gb with 64gb. Do I need all of that storage? NO! but it is easier to have it and NOT need it that it would be to be in the field or on a trip and REALLY wish that I had it. So now, my policy is to purchase the largest card of a NAME BRAND in the best class speed that I can afford. The Class speed (lowest I will purchase is Class 6) determines how fast the camera buffer can write to the card. A Class 6 (the minimum that I will purchase) is faster that a Class 3 and a Class 10 is the fastest. Note that as class speed and capacity go up, so does the price. Personally, I do NOT buy anything but Lexar and Sandisk and with Lexar's recent reorginization, I've mainly gotten Sandisk unless the Lexar price was "too good to pass up".
As for quantities, I have enough cards to be able to shoot for an estimated 2 weeks on the road without uploading and emptying my cards with backups. Now, I've never needed all of that storage, but its nice to have, and I can always use a coupld of these cards to write images to (from Lightroom or Photoshop) to take them to my nearby art/photo printer (I ALWAYS get my cards back from him).
Everybody does this differently but this is a solution that fits me and I am cofortable with. Your trials and experimentation may come up with better solutions or solutions that work better for you.

I call BS on that. I can easily remove JUST the Micro SD card from the adapter while it is in the camera. I have been doing that for a while ever since the SD card ejector crapped out and I had to send the camera off to Canon to have it repaired. By removing the Micro card only I don't stress the ejector and hopefully won't have another card get stuck in the camera.

This depends on how far into the slot the card, or adapter, goes. For some it's possible, for others it would be very difficult, if possible at all.
