While a patient is receiving antilipemic therapy, the nurse knows to monitor the patient closely for the development of which problem?

Choice A reason: Using a soft bristle toothbrush reduces gum bleeding risk in patients on heparin and warfarin, which increase bleeding tendency. This is a critical teaching point to minimize trauma and bleeding complications, making it the correct choice for safe anticoagulant therapy management.

Choice B reason: Bruising is a side effect of anticoagulants, not an indicator of effectiveness. Excessive bruising suggests overdose, requiring monitoring, not reassurance. This is incorrect, as the nurse should teach about bleeding risks, not misinterpret bruising as a sign of therapeutic success.

Choice C reason: Warfarin and heparin are not timed 2 hours apart; they are often overlapped during transition until INR is therapeutic. This is incorrect, as the nurse should teach about monitoring and overlapping therapy, not a specific timing that lacks clinical basis.

Choice D reason: Dark, tarry stools indicate gastrointestinal bleeding, a serious anticoagulant complication, not an expected outcome. Patients should report this, not expect it, making this incorrect, as the nurse should teach about bleeding signs to ensure prompt intervention, not normalize them.

Choice A reason: The Ankle Brachial Index (ABI) test compares ankle and arm blood pressure to assess arterial occlusion in peripheral artery disease. A low ABI indicates reduced blood flow, confirming diagnosis and severity, making this the correct purpose, as it directly evaluates arterial insufficiency in the lower extremities.

Choice B reason: ABI tests arterial, not venous, circulation. Deep vein thrombosis involves venous clotting, assessed by ultrasound or D-dimer, not ABI. This is incorrect, as ABI does not evaluate venous thrombosis risk, focusing instead on arterial flow and peripheral artery disease severity.

Choice C reason: Monitoring blood glucose is unrelated to the ABI test, which measures arterial blood flow. Glucose levels are checked via blood tests for diabetes management, not vascular assessment, making this incorrect, as ABI specifically targets peripheral artery disease, not metabolic conditions.

Choice D reason: Varicose veins are a venous condition, assessed visually or by ultrasound, not by ABI, which evaluates arterial flow. ABI does not measure venous insufficiency severity, making this incorrect, as the test is specific to detecting and quantifying peripheral artery disease.
