"I will have to increase my vitamin K because it is a common deficiency with this drug"
"I will need to be careful shaving and should switch to an electric razor"
"When I go for any procedures using iodine contrast I will need to let me doctor know I'm on this drug
"I need to check my pulse for a full minute before taking"
The Correct Answer is C

B. Shaving precautions are not related to metformin therapy.
C. Metformin can interact with iodine contrast used in imaging procedures, potentially increasing the risk of lactic acidosis, so it's important for the client to inform healthcare providers about their metformin use before such procedures.
