Answer to Question 1

ANS: A
Phlebitis is inflammation of a vein. Since the catheter in this situation is in an artery, phlebitis is not possible as a result of a system artery catheterization. Ischemia, hematoma, and hemorrhage are all complications of systemic artery catheterization.

Answer to Question 2

ANS: B
When a catheter faces the source of blood flow it is looking upstream. An arterial line placed in the radial artery needs to face the blood flow to accurately measure pressures that are a result of left heart work. If the catheter faces downstream it reads the pressures ahead of it. To accurately measure pressure, the transducer needs to be at the same height or level with the tip of the cathe-ter. If the transducer is higher than the catheter tip the fluid will be flowing away from the transducer and will produce a reading lower than the actual pressure.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
