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.

Answer and Explanation

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 D

Explanation

A. The client has a history of anaphylaxis following a bee sting: This finding is not directly related to the safety of taking alendronate for osteoporosis.
B. The client has a first-degree relative who has Paget's disease: While family history is

important in assessing the risk of osteoporosis, it is not a direct safety risk for taking alendronate.

C. The client is postmenopausal: Postmenopausal status is a common indication for the use of alendronate to prevent or treat osteoporosis. It is not a safety risk.
D. The client has immobility that restricts her to a supine position: Immobility, especially in a supine position, can increase the risk of esophageal irritation and reflux when taking alendronate. Therefore, this finding poses a safety risk for the client when taking this medication.
