Final answer:
When giving an antiarrhythmic drug, you would assess the patient's heart rhythm, blood pressure, medical history, and monitor their response to the drug.
Step-by-step explanation:
When giving an antiarrhythmic drug, you would assess several things on your patient. First, you would assess their heart rhythm and rate to determine the type of arrhythmia and the severity. You would also assess their blood pressure, as some antiarrhythmic drugs can affect blood pressure. Additionally, you would assess their medical history, including any other medications they are taking, to ensure compatibility and avoid potential drug interactions. Lastly, you would monitor their response to the drug, looking for any side effects or changes in their arrhythmia.
