I do believe that we are last person who can stop a potential med error. That's a huge responsibility, but one we can't take lightly. I think everyone has made a med error at one point or another, whether it was a med that was late, wrong, whatever. Sometimes I get rushed and it makes giving meds more difficult because I don't feel like I have the time to look up a dose, but I make myself. I don't know every med dosage by heart and there isn't a single soul out there that does. There are some I give so frequently, I do know without looking. Our drs. change units every month and they are often writing orders for meds they're not used to giving. All I can say is, check, check again, double check and triple check. Know your meds, look them up, know your patient, know the diagnosis, know if the med is appropriate or not. Look up the dose, check the frequency, route, etc.., If I don't know the answers to these questions, I get the Dr. and ask. It can come down to life and death. "I thought I had the right (insert patient, med, time, dose, whatever here)." doesn't hold up in court. After all, the road to he11 was paved with good intentions.
