Question 1 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: D
Rationale: The correct answer is D: Oxycodone causes central nervous system depression. Oxycodone is an opioid that acts on the central nervous system, specifically the brainstem, to depress respiratory drive. This leads to a decreased respiratory rate, as seen in the client with a rate of 8/min. The other options are incorrect because: A: Oxycodone does not inhibit prostaglandin synthesis. B: Oxycodone does not promote vasodilation of cranial arteries. C: Oxycodone does not block the sodium channel suspending nerve conduction. In summary, the client's decreased respiratory rate is due to the central nervous system depressant effect of oxycodone.
