take ibuprofen as needed for headache or other minor pains.
carry a medic alert id card.
report to the laboratory weekly to have blood drawn for aptt.
increase intake of dark green vegetables.

Explanation:

Warfarin is an anticoagulant. Clients on warfarin should carry a medic - alert ID card in case of an emergency so that healthcare providers are aware of their anticoagulant use. Ibuprofen can increase the risk of bleeding when taken with warfarin. Monitoring for warfarin is done using INR (International Normalized Ratio), not aPTT. Dark green vegetables are high in vitamin K which can interfere with warfarin's anticoagulant effect, so intake should be consistent, not increased.

Answer:

B. Carry a medic alert ID card.
