today was the 3rd day as a patient sitter. the first two hours i watched a patient and then i switched with someone to do the video monitoring. i was paying attention and right when i clicked the alarm button for one of the patients, that patient fell. thankfully there was another patient sitter in that room but was watching the patient in bed 2 since no one was assigned for the patient that fell. i felt horrible because i felt like it was my fault although i clicked on the button. i know it's not an excuse that i had no experience and since it was my 3rd day and first time with the video monitoring. i don;t know if i misheard it because i felt horrible, but i thought i heard the nurse mention the staffing nurse's name and calling saying, can you send someone because...and then i heard unreliable. so i thought it was me. there was a nursing assistant who was sitting for a patient in bed 2 and when she came out she gave me this real evil look. thankfully, that patient was okay. after an hour, i hit the alarm again for that same patient, and i saw the nurses put some spongy thing on both sides so he wont fall and took more precaution. i feel horrible and im just worried this will go into my record.
