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.

Monitoring blood pressure before changes in position can help prevent orthostatic hypotension and related complications.
B. Measure and record the client's urinary output every day: While monitoring urinary output is important for overall assessment, it may not be the most immediate concern given the client's recent surgery and medication regimen.
C. Provide the client with teaching regarding a cardiac diet: While education on a cardiac diet is important for cardiovascular health, addressing immediate concerns related to medication effects and post-surgical recovery takes priority.
D. Obtain the client's vital signs every 4 hours when awake: While vital sign monitoring is essential, the timing of every 4 hours may not be necessary during sleep, and obtaining blood pressure readings before changes in position is more critical to prevent adverse events.
