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.

B. The tubing isnt necessary when administering amphotericin B.

C. Guidelines suggest that administering by IV infusion over 2-6 hours.
D. Amphotericin B lipid complex should be administered using an infusion pump to ensure accurate dosing and control of the infusion rate, rather than relying on gravity flow.

A. Hypotension B. Tachycardia C. Diarrhea D. Insomnia

Correct Answer is A

Explanation

A. Hypotension: Hypotension can occur as an adverse effect of fentanyl, particularly if the client experiences excessive sedation or respiratory depression. Fentanyl is a potent opioid analgesic
that can cause vasodilation and a decrease in blood pressure, especially when used in high doses or in susceptible individuals.
B. Tachycardia: Tachycardia is not a typical adverse effect of fentanyl. Opioids like fentanyl typically cause bradycardia or have minimal effects on heart rate.
C. Diarrhea: Diarrhea is not a common adverse effect of fentanyl. Opioids more commonly cause constipation due to their effects on gastrointestinal motility.

D. Insomnia: Insomnia is not a typical adverse effect of fentanyl. Opioids typically cause sedation and can lead to drowsiness or somnolence, especially during initial use or when administered in high doses.
