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
B
Rationale
Correct Answer: B. Oxycodone causes central nervous system depression.
Rationale: Oxycodone is an opioid analgesic that acts on the central nervous system (CNS) to relieve pain. One common side effect of opioids like oxycodone is respiratory depression, where the CNS is suppressed, leading to a decrease in respiratory rate. In this case, the client's respiratory rate of 8/min is indicative of CNS depression caused by the oxycodone.
Summary of other choices:
A: Oxycodone does not block sodium channels to suspend nerve conduction.
C: Oxycodone does not inhibit prostaglandin synthesis.
D: Oxycodone does not promote vasodilation of cranial arteries.
Therefore, choices A, C, and D are incorrect in the context of the client's respiratory rate being 8/min.
