A patient is prescribed an additional once-daily antidysrhythmic drug to control persistent atrial fibrillation. What instructions should the nurse provide for this patient?
1. "Take your first dose of this new medication before you go to bed tonight."
2. "Do not eat or drink anything for 2 hours after taking the new medication."
3. "Before you get out of bed in the morning, sit up on the side of the bed for a few minutes."
4. "Plan to return to the clinic to have your electrolytes checked in 2 weeks."
5. "Contact the clinic if you notice any loss of hair from your head."
Correct Answer: 1,3,4
Rationale 1: The addition of a second medication makes the patient prone to hypotension. Taking the drug right before bedtime is a safety precaution.
Rationale 2: There is no reason to avoid oral intake for 2 hours after an antidysrhythmic medication.
Rationale 3: Orthostatic hypotension can be an adverse effect of antidysrhythmic medications, particularly when multiple drugs are taken. Sitting on the side of the bed before arising is a safety precaution.
Rationale 4: Electrolyte imbalance can occur secondary to drug therapy for dysrhythmia. Electrolyte levels should be monitored.
Rationale 5: Hair loss is not an expected adverse effect of antidysrhythmic medications.
