Pushing IV Lopressor

The patient is monitored, VS, 02 sat, EKG.
A strip is obtained and put on a flow sheet prior to pushing any Lopressor, if PR interval is greater than .24 we don't push any Lopressor.
The patient is intially given 15mg of Lopressor IVP over 5 minutes. VS are monitored Q 3 minutes and written on the flow sheet. If the Systolic goes below 100 we stop. We wait 15 minutes. If the HR does not reach 60 bpm we give an additional 35mg Lopressor IVP over 8 minutes. The CTA is then done regardless of the HR.
Inpatients or ER patients are returned to their unit. Outpatients must stay and be monitored for an hour following the CTA. The total amount of Lopressor given is added to the flow sheet and if going back to a unit the amount of Lopressor given is reported to the patients nurse.
