Overwhelmed and Exhausted

Hello all....In my 7th week of an 8 week orientation as a brand new nurse on a med surg floor. Orientation was originally 6 weeks, but I asked for more. The past 2 shifts have been a nightmare. Both days, with my preceptor encouraging me to take the whole group, have been incredibly inconsistent. While I'm aware and try my very best to 'roll with it", these past 2 days have seen a shuffling of patients just about every hour. Day one included a patient death with a shift of patients mid day that I knew very little about (received a mini-report from my preceptor) but I still felt clueless, then one of my pts. pased away (my preceptor and I worked this one together as it was expected, but happened faster than we originally thought). As this was a first, I felt I earnestly tried to take advantage of the learning opportunity here..ie how to care for the pt in the final minutes, how to assist the family, what phone calls needed to be made, etc. all the while dealing with my own emotions. I felt that the charge nurse should have reassigned the other pts in my care, so that I could properly attend to the situation. The second day, I received report on a pt that I had care for the day before and was told that the pt "did not look good". Made her a priority and found her to be more than just not "looking good". Notified charge and Dr and recieved a whole host of STAT orders. Charge reassigned my pts to my preceptor, who assessed 2 of the 5 and gave no morning meds to. After my one pt was stable, I found myself once gain trying to play catch up. Pt was later found, after numerous tests, to be in CHF and a potential N1H1. Pt was assigned to my preceptor as I did not pass my fit test and am unable to wear an N95 respirator. Needed to do IV restarts on 2 pts with altered mental status, missed with my first pt and she wouldn't let me come near her the rest of the day. Pt reassigned to another nurse by charge, nurse accepted pt..sort of. Find out at the end of the day, RN didn't actually take pt much to my suprise. Received new admission I wasn't told about until pt was on the floor, needed surgery consents for other Altered Mental Status pt signed by daughter and of course needed to chart (which I was horribly behind in) and take care of the other 5 pts I had. My preceptor asked me if I needed help, which I did, but I didn't even know what I needed help with. To compund all of this, the CNA was not reporting to me unstable VS on one of my pts. So at 7 pm, during change of shift report, I look up all my pts vitals and find an unstable BP.

Is this a normal day and/or days on a med/surg floor or am I just an overwhelmed new nurse?
