Answer:
There is a need to monitor closely for bleeding and review coagulation indices when accessible.
Explanation:
Combining warfarin with TCAs develops a threat for bleeding that should be assessed in the nursing care plan. There is no familiar association between the calcium supplements or bisphosphonates and TCAs, which would develop a threat of hypocalcemia. The TCAs do not elevate the threat of gastroesophageal reflux. The TCAs can influence blood pressure, however, this is not associated with any known drug-drug associations.
