A patient who is taking a monoamine oxidase inhibitor (MAOI) asks the nurse about the addition of St. John's wort to help with his depression. What would be the best response of the nurse?
"You will need to drink lots of water."
"Did you know that St. John's wort can raise your blood pressure dramatically?"
"That is a great idea. Alternative therapies can be very helpful."
"You will feel better sooner if you include phenylalanine."
The Correct Answer is B
A. "You will need to drink lots of water." This response does not address the potential drug interaction issue between St. John’s wort and MAOIs.
B. "Did you know that St. John's wort can raise your blood pressure dramatically?" St. John’s wort can interact with MAOIs and may increase blood pressure, which is a significant concern.
C. "That is a great idea. Alternative therapies can be very helpful." This response overlooks the potential for dangerous interactions between St. John’s wort and MAOIs.
D. "You will feel better sooner if you include phenylalanine." Phenylalanine is not relevant to the interaction between St. John’s wort and MAOIs.
