A nurse is teaching a client who has been prescribed warfarin for atrial fibrillation. Which of the following statements by the client indicates a need for further education?
"I will avoid eating foods that are high in vitamin K."
"I will use a soft-bristled toothbrush to prevent bleeding."
"I will monitor my blood pressure regularly at home."
"I will report any signs of bruising or bleeding to my provider."
The Correct Answer is A
A) Incorrect. The client should not avoid eating foods that are high in vitamin K, such as leafy green vegetables, because they can interfere with the anticoagulant effect of warfarin. The client should maintain a consistent intake of vitamin K and follow a balanced diet.
B) Correct. The client should use a soft-bristled toothbrush to prevent bleeding from the gums, which can occur due to the increased risk of bleeding caused by warfarin. The client should also avoid using dental floss and electric razors.
C) Correct. The client should monitor their blood pressure regularly at home, as warfarin can affect blood pressure and increase the risk of stroke or bleeding complications. The client should report any abnormal readings to their provider.
D) Correct. The client should report any signs of bruising or bleeding to their provider, as they may indicate an adverse reaction to warfarin or an overdose. The client should also report any signs of infection, such as fever, sore throat, or pus, as they may increase the risk of bleeding.

Correct Answer is C
Explanation
A) Incorrect. Metformin does not cause hypoglycemia, as it does not stimulate insulin secretion. It lowers blood glucose levels by decreasing hepatic glucose production and increasing insulin sensitivity.
B) Incorrect. Metformin absorption is not affected by food intake. The medication can be taken with or without food, but taking it with meals can help reduce gastrointestinal side effects.
C) Correct. Metformin can cause gastrointestinal upset, such as nausea, diarrhea, and abdominal pain. Taking it with meals can help minimize these effects by slowing down the transit of the medication through the digestive tract.
