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
C
Rationale
The correct answer is C: Oxycodone causes central nervous system depression. Oxycodone is an opioid analgesic that acts on the central nervous system (CNS) to relieve pain. One of the side effects of opioids like oxycodone is respiratory depression, which can lead to a decreased respiratory rate. This occurs because opioids suppress the activity of the brainstem respiratory centers, resulting in shallow breathing and decreased respiratory rate. Choices A, B, and D are incorrect as they do not directly relate to the respiratory depression caused by oxycodone. Choice A is related to local anesthetics, not opioids. Choice B is related to migraine treatment. Choice D is related to NSAIDs, not opioids.
