Symptom narrative

COVID vaccine administered at approximately 3:05 P.M in left deltoid by RN. Pt observed for 5 minutes post vaccination, client denied symptoms at this time. Client and RN observed hives in left arm around vaccination site approximately 10 minutes after vaccination. Client reports generalized itchiness but denies other associated symptoms. Pt took one Benadryl tablet, that she carries on her person, at onset of hives. Pt reports that this reaction is "normal" for her condition after exposure to many things, sometimes unidentifiable at the time of hive onset. Had RN and another observe pt and consulted care. Discussed with patient to contact provider if symptoms worsen and 911 if symptoms become severe and encouraged her to stay in department for observation for another 20 min. At 3:35p, 30 min post vaccination RN observed slight spreading of hives to back of neck and chest. Client still reports mild itchiness but denies dizziness, SOB, swelling of tongue, mouth or face. Due to other medical conditions, it was determined that this is a normal reaction for client with exposure to many things and it was decided that it was safe for patient to leave. Client walked to car by this RN.
