A prothrombin time of 45 seconds (normal 11-15 seconds) indicates severe coagulopathy and contraindications extraction. This prolonged PT suggests either excessive anticoagulation or severe liver dysfunction, both of which significantly increase bleeding risk.

Explanation: Lining the baseplate with zinc oxide-eugenol impression paste provides a more stable and accurate fit during jaw relation records. This material can help capture the contours of the underlying tissues and minimize movement of the baseplate, thus reducing the risk of displacing it during the recording process. The other options may not provide the same level of stability.
