A nurse is reviewing the medication list for a client who has a new prescription for warfarin. The nurse should recognize which is incompatible with warfarin?
Vitamin A
Alprazolam
Vitamin K
Furosemide
The Correct Answer is C
A) Vitamin A: While vitamin A can affect various bodily functions, it is not known to have a direct interaction with warfarin. Therefore, it is not considered incompatible with warfarin therapy.
B) Alprazolam: This medication, a benzodiazepine, is primarily used to treat anxiety and does not have a significant interaction with warfarin. Thus, it is not incompatible with warfarin therapy.
C) Vitamin K: This vitamin is a critical consideration when a client is on warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, so an increased intake of vitamin K can counteract the effects of warfarin, making this the correct answer. Clients on warfarin should maintain a consistent intake of vitamin K to prevent fluctuations in their INR levels.
D) Furosemide: This loop diuretic is used to manage conditions such as heart failure and edema. While it may affect electrolyte levels, it does not have a direct interaction that would render it incompatible with warfarin. It can be safely used alongside warfarin with appropriate monitoring.

Correct Answer is A
Explanation
A. "Diuretics are the first line therapy to control hypertension.": This statement is accurate. Thiazide diuretics are commonly recommended as first-line treatment for mild hypertension, as they help reduce blood volume and lower blood pressure effectively.
B. "Reaching your goal blood pressure will occur within 2 months.": While treatment can lead to improvements in blood pressure, the timeline for reaching target levels can vary significantly among individuals based on adherence to lifestyle changes and medication. It's important to communicate that achieving the goal may take longer than two months.
C. "Plan to add saturated fats to 10 percent of your daily calorie intake.": This recommendation is misleading. Guidelines generally suggest limiting saturated fats to less than 10 percent of total daily calories to promote heart health, not adding them.
D. "Limit your alcohol consumption to three drinks a day.": This statement is also inaccurate. For most adults, the recommendation is to limit alcohol to no more than two drinks per day for men and one drink per day for women to help manage blood pressure effectively.
