Answer to Question 1

ANS: A
To avoid this problem during continuous use in humidified circuits, the clinician should place the analyzer sensor proximal to any humidification device.

Answer to Question 2

ANS: B
Invasive procedures require the insertion of a sensor or collection device into the body, whereas noninvasive monitoring is a means of gathering data externally. Because laboratory analysis of gas exchange requires blood samples, it is usually considered invasive. On the other hand, moni-toring can be either invasive or noninvasive. In general, invasive procedures tend to provide more accurate data than do noninvasive methods but carry greater risk.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
