I made a medication error. I accidentally gave an IV bolus of 300ml 3% sodium chloride instead of 0.9 Normal Saline. I scanned the medication put for some reason I still missed it. Another RN caught the mistake after the bolus finished. I reported the medication error and told the doctor. The patient did not have any side effects and sodium recheck level was normal. I am completely devastated and feel terrible. I am worried about what management will do.
