As a supervisor, I'm wondering how this fell through so many cracks. How did other nurses not question the new antibiotic? Why didn't the MD check the orders within 24 hours? How did the pharmacy not question the new order? How did infection control not question the order? You were only a part of the error. The fact that you noticed it at all, seems to be the good news here. Don't be so spazed. You are now a professional nurse, not a hysterical school girl. Patients, staff, families and your own family and friends will appreciate your expertise much more when you are calm and in control of your emotions. Your husband does not deserve to be driven nuts. He is hoping for you to be happy and satisfied with the career you just spent a fortune getting. As an experienced nurse, I can tell you that getting worked up and bringing emotional trash home is a very negative and personally destructive thing to do. It is, by far, the most difficult part of nursing that I faced. It breaks my heart to see my young nurses succumb to it. It is possible that you may face termination. It's a shame, if you do. But if that is the mentality of your institution, it's better to find out now and move on, anyway. Why work in a sloppy and unsupportive environment?
