A 78-year-old male is alert and oriented to person, place, and time and complains of chest pain and difficulty breathing. You attach him to the ECG and notice a rhythm of 42 with corresponding pulse, a P-R interval of 0.20, and normal R-R intervals. Vitals are BP 76/42, respirations 42. The patient also states that he feels nauseated and dizzy. Treatment for this patient should include
