Question 1
pts
I understand the value of doing my own work and learning this skill to support my future independent practice
as a nurse practitioner. I understand that while there may be opportunities beyond my faculty’s control to
collaborate or share answers with peers, that it would not benefit my own personal and professional growth to
do so. I agree to do my own work and take personal responsibility for my learning.
I do not.
Correct!
I do.

treatment with metformin.
Question 5
pts
Use the John Jones case study to answer the following question.
Which behavior in John’s social history poses a potential concern with initiating metformin?
His diet largely consists of fast-food meals. He drinks sweet tea with every meal.

Metformin is contraindicated in alcoholics. Although it does not sound as if John is an alcoholic, further
