While assessing a patient the nurse notes that the patient's ankle-brachial index (ABI) of the right leg is 0.40. How should the nurse best respond to this assessment finding?
A) Assess the patient's use of over-the-counter dietary supplements.
B) Implement interventions relevant to arterial narrowing.
C) Encourage the patient to increase intake of foods high in vitamin K.
D) Adjust the patient's activity level to accommodate decreased coronary output.
Ans: B
Feedback:
ABI is used to assess the degree of stenosis of peripheral arteries. An ABI of less than 1.0 indicates possible claudication of the peripheral arteries. It does not indicate inadequate coronary output. There is no direct indication for changes in vitamin K intake and OTC medications are not likely causative.
