A nurse is caring for a client who has a life-threatening ventricular dysrhythmia. Which of the following medications should the nurse anticipate administering?

Verapamil

Digoxin

Dopamine

Amiodarone

Answer and Explanation

The Correct Answer is D

A. Verapamil: Verapamil is a calcium channel blocker primarily used to treat supraventricular

tachycardias, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular dysrhythmias.
B. Digoxin: Digoxin is a cardiac glycoside used primarily for atrial fibrillation and heart failure, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular
dysrhythmias.

C. Dopamine: Dopamine is a sympathomimetic medication used for hemodynamic support in hypotension and shock. While it may be used in some cases of unstable bradycardia, it is not the first-line medication for life-threatening ventricular dysrhythmias.
D. Amiodarone: Amiodarone is an antiarrhythmic medication used for the treatment of various ventricular and supraventricular dysrhythmias, including life-threatening ventricular
dysrhythmias such as ventricular tachycardia and ventricular fibrillation. It is often used as a first-line medication for these conditions due to its efficacy and safety profile. Therefore, the nurse should anticipate administering amiodarone for the client's life-threatening ventricular dysrhythmia.

Correct Answer is A

Explanation

C. Asking about pain level assesses intensity, not quality.

D. Asking about the timing of pain increasing assesses onset, not quality.

A. Oxycodone blocks the sodium channel suspending nerve conduction. B. Oxycodone inhibits prostaglandin synthesis. C. Oxycodone promotes vasodilation of cranial arteries. D. Oxycodone uses central nervous system depression.

Correct Answer is D

Explanation

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.
