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.
