A client is admitted to a cardiac care unit for chronic hypertension. The client has been struggling to take their medications appropriately and acute management was required to gain control of the client’s hypertension. The client had recently been having several high blood pressures in the morning and was prescribed amlodipine (Norvasc®) 5 mg PO daily. Prior to the first administration of the amlodipine (Norvasc), the client’s vitals read: heart rate 80, respiratory rate 10, \(O_2\) 100%, and blood pressure 80/50. Which action by the nurse is most appropriate?
