The nurse is caring for a client during a cardiac arrest. The monitor displays the rhythm below. Which intervention should the nurse perform at this time?
Administer amiodarone 200 mg IV push
Defibrillate the client using 200 joules
CPR until the physician stops the code
Administer adenosine 12 mg IV push
The Correct Answer is C
A. Administer amiodarone 200 mg IV push: Amiodarone is used for shockable rhythms like ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) that are refractory to defibrillation. The rhythm on the monitor is asystole, which is non-shockable, and amiodarone is not indicated here.
B. Defibrillate the client using 200 joules: Defibrillation is only appropriate for shockable rhythms such as VF or pulseless VT. Asystole is not shockable, and defibrillation in this rhythm would be ineffective and inappropriate.
C. CPR until the physician stops the code: The rhythm strip shows asystole, a flatline with no electrical activity. The priority intervention is to initiate and continue high-quality cardiopulmonary resuscitation (CPR) immediately and continue until the code is terminated by the physician. This is consistent with Advanced Cardiac Life Support (ACLS) guidelines.
D. Administer adenosine 12 mg IV push: Adenosine is used to terminate supraventricular tachycardia (SVT) and is not indicated in asystole or during cardiac arrest. It would have no effect in a rhythm with no electrical activity.

Correct Answer is A
Explanation
A. Ensure all tubing connections are tightened: Tight tubing connections are critical in preventing accidental disconnection, which can result in rapid blood loss and air embolism. Arterial lines are under high pressure, so securing all connections is a top priority to ensure patient safety and maintain line integrity.
B. Apply a pressure dressing to the insertion site: A transparent occlusive dressing not a pressure dressing is used for arterial lines to allow for site visualization and reduce the risk of infection. A pressure dressing could obscure signs of bleeding or compromise the catheter’s position.
C. Perform an Allen's test: Allen’s test is performed prior to radial arterial line insertion to assess collateral circulation via the ulnar artery for preventing ischemic complications if the radial artery is compromised. Performing the test afterward does not prevent complications and is no longer relevant once the catheter is placed.
D. Obtain a portable x-ray to confirm placement: X-rays are used to confirm the placement of central lines, not peripheral arterial lines like the radial line. Arterial line placement is confirmed by waveform analysis and blood return, not imaging.
