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?
Oxycodone blocks the sodium channel suspending nerve conduction.
Oxycodone inhibits prostaglandin synthesis.
Oxycodone promotes vasodilation of cranial arteries.
Oxycodone uses central nervous system depression.
The Correct Answer is D
A. Oxycodone primarily exerts its analgesic effects through binding to opioid receptors and modulating neurotransmitter release, rather than blocking sodium channels.
B. Oxycodone does not directly inhibit prostaglandin synthesis; this mechanism is associated with nonsteroidal anti-inflammatory drugs (NSAIDs).
C. Oxycodone does not promote vasodilation of cranial arteries. This mechanism is more commonly associated with medications used to treat migraines, such as triptans.
D. Oxycodone is an opioid analgesic that acts centrally on the nervous system to depress respiratory drive, leading to respiratory depression, especially at higher doses.

Correct Answer is C
Explanation
A. This statement is incorrect. While it’s essential not to exceed the recommended dose, the
maximum daily limit for nicotine gum is 24 pieces, not 40. Using more than the recommended amount can lead to adverse effects
B. This information is not accurate. Nicotine gum is typically used for a shorter duration. The
treatment plan varies, but it’s essential to follow the recommended dosing and gradually reduce usage over time. The goal is to quit smoking successfully, not to use the gum for 9 months
C. This advice is correct. Nicotine gum is not used like ordinary chewing gum. You should chew it a few times and then “park” it between your cheek and the space below your teeth. The nicotine is absorbed mostly in your mouth. Chewing it slowly over 30 minutes allows for
effective absorption and helps control withdrawal symptoms
D. Drinking water before chewing nicotine gum is not a necessary instruction for its use.
