Answer :
Final answer:
The most appropriate action for the nurse in this scenario would be to (4) call the primary caregiver and report the client's assessment findings due to potential respiratory complications.
Explanation:
Given the client's current state, the nurse's best plan of action is to phone the client's primary healthcare practitioner and inform them of the results of the evaluation. The client's persistent drowsiness and diminished O₂ saturation levels even after the administration of nasal oxygen indicate potential respiratory complications, potentially a repercussion of the medication (oxycodone/acetaminophen) administered.
Oxycodone is an opioid and could suppress the client's respiratory drive, leading to diminished oxygen saturation. This is a serious condition that needs to be addressed right away. Hence, option 4 appears to be the most appropriate in this scenario.
