B. Titrating oxygen within prescribed parameters is an appropriate task for a PN, as it involves following provider orders and monitoring the client's response while working under RN supervision.
C. Receiving a postoperative client and conducting the initial assessment requires comprehensive assessment skills, which fall within the RN's scope of practice rather than the PN's.

Correct Answer is C
Explanation
A. Increasing the intake of dark green leafy vegetables while taking warfarin can affect INR levels due to their high vitamin K content, potentially increasing the risk of bleeding.
