Assuming that they have not responded to drug therapy, which of the following clients is likely to be the best candidate for surgical cardiac ablation?
 
  A)
  A 62-year-old woman with peripheral vascular disease who has experienced multiple episodes of torsade des pointes
  B)
  A 75-year-old man with diabetes but no previous heart disease that suddenly develops syncope due to sick sinus syndrome
  C)
  A 46-year-old man with unstable angina and a history of myocardial infarction who is found to have long QT syndrome and episodes of frequent ventricular arrhythmias
  D)
  A 22-year-old woman with an atrial septal defect who has recurrent paroxysmal atrial flutter with rapid ventricular rate associated with her caffeine intake.

Question 2

  A 23-year-old male who has an injury to his frontal lobe following a sports injury
  B)
  A 45-year-old female with a spinal cord injury at C7 following a motor vehicle accident
  C)
  A 34-year-old male with damage to his upper and lower pons following a blow to the back of the head

Answer to Question 1

Ans:
C

Feedback:

Due to his history of MI, the 46-year-old man probably has several areas of necrotic tissue that are interfering with conduction and ventricular function and would probably benefit from having them removed. The 62-year-old woman may have little or no myocardial tissue damage, so a less invasive procedure to improve her cardiac circulation would be a better choice for her. The 75-year-old man may not have any areas of infarction and is a risky surgical candidate because of his age and diabetes. The 22-year-old woman's tachycardia is likely to be nonischemic in origin.

Answer to Question 2

Ans:
C

Feedback:

The respiratory center is located in the pons. Damage to the temporal lobe, frontal lobe, or spinal cord at C7 is less likely to affect respiration.
