question 52

Multiple Choice

Which statement is true regarding monitoring anticoagulant therapy in patients with a LA?

• A) If the patient's PT and international normalized ratio (INR) were within normal range before starting warfarin, then the INR can be used for therapeutic monitoring.
• B) Because the APTT is prolonged in people with LA, the PT has to be used to monitor heparin therapy.
• C) Because the patient has an LA, if he or she is receiving warfarin therapy, an INR of no more than 2.0 is adequate.
• D) If the patient is receiving warfarin, then a chromogenic factor X assay may be needed. If the patient is receiving heparin, then a chromogenic anti-factor Xa (heparin assay) should be used if monitoring is required.
• E) The physician should use his or her best judgment regarding dosing of anticoagulants because it is impossible to monitor anticoagulant therapy in people with LA.
