I'm a student. I was in my last Med/surg rotation (telemetry floor). I went to get pt. vital signs in the morning and she wanted her BP taken on her forearm. So, I did. She said it was due to her very large arms and it pinched when you take it on her upper arm. I got a BP of 163/87 (dynamap). BP was slightly high so I wanted to give her 9AM meds which included some BP meds before any other intervention. I administered her medication and I went back at about 1130 and did her VS again and her BP(forearm-dynamap) was 166/91 this time.
I checked her PRN and she had an order of hydralazine 10mg (0.5ml) IVP. So, I administered the hydralazine @1245 IVP. I went back around 130PM and took her BP on her forearm. It was 198/100. I was thinking OMG how the heck is it that high after administered her hydralazine. At the time the nurse was coming into the room so I showed the nurse the vitals on the dynamap. The nurse questioned it and thought "that's not right." I told the nurse I was taking her BP on her forearm because the pt. felt like it was more comfortable. The nurse found a larger BP cuff and took the BP on the upper arm. BP this time was 139/93. Nurse said, "that's better." and that was it....and I went home.
Soooo, basically, 3 days later I'm freaking out because I could have caused my patient's BP to drop. I was probably getting the wrong BP reading the entire day by taking it on the forearm, and then I go and push hydralazine!! I feel so bad about doing that. Here I thought, I'm doing great in clinical, and I go and do this.......I emailed my instructor b/c she doesn't know what happened and I didn't really worry about it or even THINK about taking the BP on the forearm as a big deal, until now. Could 10mg (0.5ml) of hydralazine really cause my patient's bp to drop to the point that she could die? I feel so bad......I think I might get kicked out of school b/c of this mistake......I'm waiting to hear back from my instructor....
