Answer to Question 1

ANS: D
Appropriate precautions must be taken when using all lasers. The caregiver must protect their eyes with special goggles. The patient's skin, eyes, respiratory tract, and tissue must be protected from thermal burns.

Answer to Question 2

ANS: A
The bipolar unit may be used with any type of model because the current does not pass through the patient's body. The current does not pass beyond the tines of the forceps; therefore, it will not disrupt the pacemaker.
