A 35-year-old man visits his doctor with complaints of shortness of breath, dizziness, palpitations, and chest pain. The Px has a history of paroxysmal atrial dysrhythmia and has been on 400 mg quinidine three times a day for the past year. Since starting the medication, he hasn’t had another episode. The patient is the CEO of a local software company and lives alone. He claims he just had a severe case of the flu, which left him with diarrhea and vomiting for five days. He has, however, been feeling better, has resumed his medicine, and has returned to work the day before. Physical examinations reveal that he is awake and alert, although he feels dizzy. His breathing rate is 28 breaths per minute, yet all lobes have clear lung sounds. Despite the fact that his bowel sounds are normal, he is experiencing nausea. His pulse is 150 and erratic, and his blood pressure is 102/56. His nailbeds are pink, and his oxygen saturation level is 96.
