Final answer:
The expected outcome of taking an antidysrhythmic drug would generally be the correction of an irregular heart rhythm without directly affecting CO2 levels or leading to organ insufficiency.
Step-by-step explanation:
An expected outcome of a patient taking an antidysrhythmic drug would most likely be a normalization of heart rhythm, as these drugs are designed to correct irregularities in the heart's electrical signaling. The options provided, such as increased CO, increased renal insufficiency, and increased hepatic insufficiency, do not directly relate to the intended outcomes of antidysrhythmics.
The correct answer to the options given would depend on the specific drug and its known side effects or mechanisms, but commonly antidysrhythmic drugs can lead to an improvement in cardiac function without necessarily altering CO2 levels or causing organ insufficiency. However loop diuretics, which are sometimes used alongside antidysrhythmics to manage conditions like hypertension, can cause an increase in urination by inhibiting reabsorption of sodium and chloride in the loop of Henle affecting fluid and electrolyte balance.
