Answer to Question 1

ANS: D
A normal pulse is described as +3. A pulse that is easy to palpate and not easily obliterated with pressure is considered normal. A pulse graded 0 is not palpable. A pulse graded +1 is difficult to palpate, thready, weak, and easily obliterated with pressure. A pulse graded +2 is difficult to palpate and may be easily obliterated with pressure.

Answer to Question 2

ANS: A
The axillary sensor measures the infrared heat energy radiating from the axilla. It can be used on wet skin, in incubators, or under radiant warmers. Ear thermometry does not show sufficient correlation with established methods of measurement. It should not be used when body temperature must be assessed with precision. Mercury thermometers should never be used. The release of mercury, should the thermometer be broken, can cause harmful vapors. Rectal temperatures should be avoided unless no other suitable way exists for the temperature to be measured.
