Chapter 25 : Antidysrhythmic Drugs Questions
Question 1 of 5
A patient is in the emergency department with a new onset of rapid-rate atrial fibrillation, and the nurse is preparing a continuous infusion. Which drug is most appropriate for this dysrhythmia?
Correct Answer: A
Rationale: Diltiazem is used for rate control in atrial fibrillation by slowing AV node conduction, making it appropriate for rapid-rate atrial fibrillation. Atenolol, lidocaine, and adenosine are not primarily used for this purpose.
Question 2 of 5
The nurse notes in the patient's medication orders that the patient will be taking ibutilide. Based on this finding, the nurse interprets that the patient has which disorder?
Correct Answer: B
Rationale: Ibutilide, a class III antidysrhythmic, is used to convert atrial fibrillation or flutter to normal sinus rhythm. It is not indicated for ventricular ectopy, supraventricular tachycardia, or bradycardia.
Question 3 of 5
Which patient-teaching instructions are appropriate for a patient taking an antidysrhythmic drug? (Select all that apply.)
Correct Answer: A,B,E
Rationale: Appropriate instructions include not chewing/crushing extended-release forms, taking with food for GI distress, and limiting caffeine due to its cardiac stimulant effects. Doubling doses, using antacids, or reporting wax matrices in stool (normal for some formulations) are incorrect.
Question 4 of 5
The nurse is monitoring for adverse effects in a patient who is receiving an amiodarone infusion. Which are adverse effects for amiodarone? (Select all that apply.)
Correct Answer: B,D,F,G
Rationale: Amiodarone can cause constipation, QT prolongation, hypotension, and blue-gray skin discoloration due to its complex pharmacology. Tachycardia, chest pain, and headache are not typical adverse effects.
Question 5 of 5
The nurse is preparing to administer a bolus dose of verapamil as follows: 'Give 5-mg bolus of verapamil, IV push, over 2 minutes. May repeat in 30 minutes if needed.' The medication is available in a 2.5-mg/mL strength solution. Identify how many milliliters will the nurse draw into the syringe for this dose.
Correct Answer: 2 mL
Rationale:
To calculate: 2.5 mg/1 mL = 5 mg/x mL. Cross-multiply: (2.5 * x) = (1 * 5); 2.5x = 5; x = 5/2.5 = 2 mL.
