A client is scheduled for a coronary artery bypass graft (CABG) in the morning using a saphenous vein. The physician does not use the internal mammary artery for the bypass graft, because the internal mammary artery:
- A. takes more time to remove.
- B. has a greater risk of becoming reoccluded.
- C. is smaller in diameter.
- D. has too many valves.
Correct Answer: A
Rationale: Many physicians do not use the internal mammary artery because it is time consuming. Removing the internal mammary artery does not pose a greater risk of reocclusion. In fact, it may stay patent longer. The internal mammary artery is larger in diameter than the saphenous vein. The internal mammary artery does not have too many valves.

Which of the following would you include as risk factors for the development of skin cancer when assessing the integumentary system?
- A. Advancing age
- B. Positive family history
- C. Dark pigmentation
- D. White collar job
Correct Answer: B
Rationale: Advancing age by itself is not a risk factor. If that person has been exposed to a lot of sun there may be increased risk, but that information is not given here. There is a known genetic risk, with some cancers being seen to be present in families with low risk factors. Those with dark pigmentation develop skin cancer, but at a lower rate than those with low amounts of pigmentation. White collar jobs, which occur in offices and inside buildings, are a low risk for skin cancer.
