Iron does this. I've known people who were taking iron supplements and it made their burps smell like burnt rubber. So I'm assuming it would cause the same coming out the other end. I'm GI bleed too, being that iron is readily found in blood.
I'm a new grad and recently passed the NCLEX. I finally got my official license in the mail. I was expecting a card of some sort. I've talked to friends in other states (I applied out of state) and they said their state gave them a card. NC gave me a certificate (piece of paper with a NCBON seal on it). Is this normal to get a certificate instead of a card (a driver's license type card)?
