Answer to Question 1

ANS: A
Because of the large magnets in the MRI cabinet, the pacemaker may be reset to a fixed mode and interfere with the functioning of the pacemaker.

Answer to Question 2

ANS: B
Suggestion of a stasis ulcer in the making is an edematous, dry scaly area on the medial surface of the lower leg that has a darker pigmentation (rubor). Cool hairless limbs with absent or weak pedal pulses are indicative of arterial insufficiency.
