Rationale 3: Anticoagulants do not decrease the number of platelets.
Rationale 4: Heparin inhibits the clotting cascade, preventing clots from forming.
Global Rationale: Heparin inhibits the clotting cascade, preventing clots from forming. Anticoagulants do not dissolve clots, change the viscosity of the blood, or decrease the number of platelets.

Answer to Question 2

Correct Answer: 3
Rationale 1: The INR is in the therapeutic range.
Rationale 2: The INR is in the therapeutic range, and the warfarin does not need to be increased.
Rationale 3: INR values averaging 2.5 are considered therapeutic for most indications.
Rationale 4: The INR is in the therapeutic range.
Global Rationale: INR values averaging 2.5 are considered therapeutic for most indications. The INR is in the therapeutic range, and the warfarin does not need to be increased.
