Final answer:
The nurse assesses for an increased risk of bleeding in patients who have taken gingko before surgery because of its blood-thinning effects.
Step-by-step explanation:
The nurse should assess a patient who took gingko prior to surgery for an increased risk of bleeding. Gingko has been known to have anticoagulant, or blood-thinning effects, which can lead to this surgical complication. Unlike the other options, which are not commonly linked to gingko usage, the risk of excessive bleeding is a well-documented concern and must be addressed by healthcare professionals prior to any surgical procedure to ensure patient safety.
