Answer to Question 1
Correct Answer: 3
Rationale: Changes in sodium, potassium, and calcium levels generate the action potential in myocardial cells. For this to occur, the patient must have normal levels of sodium, potassium, and calcium. Changes in sodium, potassium, and calcium, not magnesium, levels generate the action potential in myocardial cells. Antidysrhythmic drugs work by blocking, not enhancing, potassium, sodium, or calcium channels. Sodium, potassium, and calcium are equally important when it comes to the myocardial action potential.
Answer to Question 2
Correct Answer: 2,3
Rationale: Atrial fibrillation is the most common type of dysrhythmia. The physician will determine whether to use nonpharmalogical techniques such as cardioversion, or an implantable cardioverter defibrillator (ICD), or medication. Medications can cause serious side effects and are normally reserved for patients with overt symptoms, or for patients whose condition cannot be controlled by other means. Ventricular dysrhythmias are more serious than atrial dysrhythmias because they are more likely to interfere with the normal function of the heart. Heart transplants are not indicated for patients with dysrhythmias.
