So here's the story: on my clinical cal day it's hard to find our instructor, it's a large unit and there's 8 of us with 2 patients each so I can't always ask her for advice. I was at the Pyxis pulling my amplodipine for my patient and the dose was 15mg. The Pyxis asked how many 5 mg packets I was removing and I said 3. The drawer and pocket opened and I removed the packets. When I was double checking two of the packets were very stuck together so I had to yank them apart so I technically pulled 4 packets. I asked a nurse nearby what to do and she said just return it to the Pyxis so I did that. Then I double check my med with my instructor and she gave me the go ahead to administer them. Prior to scanning them I noticed that one of the three packets was actually a 10mg tablet and the other two were 5 mg. So I scanned and administered the 10mg and one 5mg and asked a nurse what to do since I couldn't find my instructor and she said to just return the extra tablet to the Pyxis. My concern is that there will be a discrepancy on the Pyxis since I said I was only pulling three packets but administered two and returned two. Any advice?
