I just bought Nikon D7000 on last 2 days and found that every photo that uses ISO from 1600 will have 3 hot pixels at the same position.
Then I took the photo with lens cap and test with dead/hot pixel tester, here is the result.

On ISO 100-400 not found any dead/hot pixel on every shutter speed (tested from 1/125 – 2”)
ISO 800 s1/8 3 hot pixels
ISO 1600 s1/125 found 1 hot pixel
ISO 1600 s1/60 found 1 hot pixel
ISO 1600 s1/8 found 3 hot pixels
ISO 3200 s1/125 found 3 hot pixels

Firmware A 1.02 /B 1.02 /L1.002 and not have the problem of hotpixel on video mode.

The question is my camera is acceptable or should I return to the Nikon Shop?

Are they visible in a normal (non-lens cap) photo?

If you don't have them now, you will get them in the future. It's like going gray or bald.

Some raw converters will automatically remove them for you.

I have not tested my D7000 but I can find no evidence of any when examining my photos.

On my D40 I developed several bad ones but I managed to use some software to remove them when shooting above ISO 800. (pixelfixer)

If you are not happy, take it back but with 16 million pixels I wouldn't expect absolute perfection.
