What is the right order???

I am a student nurse and had a patient charted for Hypersal via NEBS, salbutamol puffer, and atrovent puffer. I learnt from uni to give brochodilators first then the hypersal but my Nurse educator says otherwise? And now I am confused as she assessed me and ask the order in administering these meds and I said salbutamol first to open up airways then atrovent and lastly hypersal to moisten and thin out mucus but she marked me off not yet competent while giving the meds to my pt. This might be a silly question but which one do we really give first???
