Answer to Question 1

B
Antacids interfere with the absorption of gabapentin. At least 2 hours should be scheduled be-tween doses of gabapentin and any antacid.

Answer to Question 2

D
Primidone decreases the effectiveness of anticoagulants, including warfarin. Warfarin effective-ness is measured by the INR. This value should be no less than 1.5 in a patient taking warfarin. With an INR level of only 0.5 the patient is at risk for forming clots and having a stroke, heart attack, pulmonary embolism, or deep vein thrombosis.
