A nurse in a clinic is caring for a client who has recently begun taking warfarin. The nurse is reviewing potential drug and food interaction risks and should instruct the client to avoid which of the following?
Cabbage
Green beans
White beans
Cantaloupe
The Correct Answer is A
A. Cabbage: This is the correct answer. Cabbage is a food high in vitamin K, which can antagonize the effects of warfarin. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-rich foods, such as cabbage, can affect the stability of the client's international normalized ratio (INR).
B. Green beans: Green beans are not particularly high in vitamin K, and their consumption is not usually restricted for clients taking warfarin.
C. White beans: White beans are not particularly high in vitamin K, and their consumption is not usually restricted for clients taking warfarin.
D. Cantaloupe: Cantaloupe is not high in vitamin K, and its consumption is not usually restricted for clients taking warfarin.

Correct Answer is C
Explanation
A. Impaired tissue perfusion: While impaired tissue perfusion is a concern in clients with varicose veins, the presence of ulcerations indicates that skin integrity is already compromised. Addressing impaired skin integrity is a more immediate concern.
B. Alteration in activity tolerance: Alteration in activity tolerance may be a consequence of impaired tissue perfusion and impaired skin integrity, but the priority is to address the current skin breakdown and prevent further complications.
C. Impaired skin integrity: This is the correct answer. The presence of varicose veins, ulcerations, and lower extremity edema indicates compromised skin integrity. The nurse should prioritize interventions to promote wound healing, prevent infection, and address the underlying causes contributing to impaired skin integrity.
D. Alteration in body image: While body image concerns may arise in clients with varicose veins, the immediate priority is addressing the physical complications such as impaired skin integrity to prevent further deterioration.
Correct Answer is D
Explanation
A. Serum amylase: Serum amylase is an enzyme associated with pancreatic function, and its elevation is not specific to myocardial infarction.
B. Unconjugated bilirubin: Elevation of unconjugated bilirubin is associated with liver function and hemolysis, not specifically with myocardial infarction.
C. Aspartate aminotransferase (AST): While AST may be elevated in conditions affecting the heart, it is not as specific or sensitive for myocardial infarction as troponin I.
D. Troponin I: This is the correct answer. Troponin I is a cardiac-specific biomarker released into the bloodstream when there is damage to cardiac muscle, such as during a myocardial infarction. Troponin I levels start to rise within 3-4 hours after the onset of myocardial infarction, making it a crucial marker for early detection.
