When giving dofetilide to a patient with renal dysfunction, the dosage must be calculated according to the patient's creatinine level to ensure the therapeutic effect while limiting toxicity. This drug can only be administered by oral route. Intake and output as well as breath sounds may need to be assessed but are not related to administering the drug. A patient in atrial fibrillation will not have a measurable PR interval.
