Someone please help! Can I lose my liscense?

[marriednextmonth]

I am a newer nurse. I recently started my first heparin drip. I was unsure how to after reading the policy so I asked a seasoned nurse to help me. Together we looked at the policy, checked the ptt (i believe it was the ptt, scared i might have checked the pt) and started the drip per protocol. I reported off to the night shift nurse that the ptt was going to be rechecked in 30 minutes (the 6hr window was up). before leaving i saw the lab come in and draw the blood. the next morning i came to work and the drip had not been titrated all night nor had the ptt been checked again. The night shift nurse also completed her 24 chart checks. At the end of my shift my boss told me that i was suspended until completion of investigation because i was the one who checked off the orders. Im worried that i may not have checked the paperwork right and am now scared i am going to lose my job or my liscense. someone please help me! can I lose my liscense over this? i am a single mother and am very scared.
