Answer to Question 1

Correct Answer: 2
Rationale: Hypokalemia and hypomagnesemia should be corrected prior to initiating therapy with amiodarone (Cordarone). 5.1 mEq/L is a normal potassium level. 140 mEq/L is a normal sodium level. Twelve seconds is a normal international normalized ratio (INR) level.

Answer to Question 2

Correct Answer: 3
Rationale: Verapamil (Calan) should be used with caution with herbal supplements, such as hawthorn, because of the potential for additive hypotensive effects. All herbal supplements, not just St. John's wort, should be avoided. Taking calcium salts with herbal supplements will not affect the interactions with verapamil (Calan). Herbal supplements may lower, not increase, blood pressure.
