For SIM lab, I was the primary RN. I received bedside SBAR report about my patient. My patient was admitted with “indigestion” and back pain. When I was doing my assessment, my patient denied any pain, but suddenly, she started complaining of back pain 6/10. The tech took her V/S while the charge nurse and I were figuring out what interventions or orders to use for my patient’s back pain. Her BP and HR were elevated, and I did not have any PRN order for antihypertensive drug whatsoever. She was desaturating, thus I titrated the O2 from 2 L to 6 L, her O2 went back to baseline. However. My patient stated that her pain was increasing and asked me if she could have the same med that was given previously in the ED (sublingual nitro) for her back
