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 B
Explanation
A. Cardiovert in the synchronized mode: Synchronized cardioversion is used for hemodynamically unstable but conscious patients with rhythms like atrial fibrillation or supraventricular tachycardia. It is not appropriate for a pulseless patient with ventricular fibrillation, as synchronization requires detectable R-waves.
B. Defibrillate immediately with a biphasic machine: The rhythm strip shows ventricular fibrillation (VF) a life-threatening arrhythmia characterized by chaotic, irregular waveform with no identifiable PQRST and no effective cardiac output. The patient is unresponsive and pulseless, making immediate defibrillation the priority action, as per Advanced Cardiac Life Support (ACLS) guidelines.
C. Take a full set of vital signs: The client is already unresponsive and pulseless, making a full set of vitals irrelevant at this moment. Immediate resuscitation efforts, including defibrillation and CPR, take priority.
D. Initiate cardiopulmonary resuscitation: While CPR is a critical part of the algorithm for pulseless rhythms, defibrillation is the first priority in ventricular fibrillation when a defibrillator is available and ready. CPR should be started immediately after the shock if no pulse returns.
Correct Answer is A
Explanation
A. ambulate in the hall 3 times daily without shortness of breath: This directly reflects improved tolerance to activity, the central focus of the nursing diagnosis. Being able to ambulate without dyspnea indicates better cardiac output and ventricular function, marking resolution of the identified problem.
B. have an increase in systolic blood pressure of 20 mmHg during activity: A rise in systolic pressure may occur with exertion, but it does not necessarily indicate improved activity tolerance. In fact, an exaggerated BP response could indicate the heart is working harder than it should to meet the demands, suggesting poor cardiovascular adaptation to exercise.
C. decrease weight from 150 lbs. (68.2 kg.) to 148 lbs. (67.3 kg.) in five days: A slight weight reduction may reflect decreased fluid retention, but this outcome is more relevant to volume status and fluid balance than to resolving activity intolerance specifically.
D. verbalize the signs and symptoms of worsening heart failure by discharge:
While important for client education and self-management, this outcome relates to knowledge rather than physical tolerance to activity. It does not directly measure resolution of activity intolerance.
