Answer to Question 1

ANS: A
Artifacts are frequently seen, for example, when the patient or monitoring lines are moved.

Answer to Question 2

ANS: C
The signal itself can exhibit a random variability related to the inherent imprecision of the signal or due to normal physiologic variability in the patient. Blood pressure, for example, changes within a certain range for many reasons.
