Question: Your partner is preparing O2, obtaining vitals and attaching the monitor for a chest pain patient. You are performing a primary survey, gathering your SAMPLE Hx, ruling the patient in protocol for ASA, giving the ASA and doing the same for Nitro. Vitals are obtained 3-4 minutes earlier than the Nitro administration.

From past experience and following the protocol which states vitals q5 min, nitro q5 min and vitals must be obtained within 5 minutes of medication delivery, is this improper as 3 minutes has lapsed prior to the nitro administration? I have been informed that past deactivation has resulted from this?
