If I buy an item 100% for business and claim it as a business expense, and later sell it at a loss, do I have to claim that sale income since I sold it at a loss?

I am self-employed and bought an item 100% for business and claimed it as a business expense.

If I later sold that item at a loss do still I have to pay taxes on that income, or claim that income, since I sold it at a loss?

And if I do have to claim that sale at a a loss as income, can I put down the original higher price I paid for the item as my cost-basis, even though I already claimed it as a business expense separately.

Thank you.
