Rhythm Strip
The nurse is evaluating the following rhythm strip on a client in the telemetry unit. The client is alert and oriented but is complaining of slight nausea after eating breakfast. What is the nurse's best action?
Complete the remainder of the assessment.
Obtain an order for adenosine IV.
Notify the physician of the symptoms.
Administer the prescribed ace inhibitor.
The Correct Answer is C
A. Complete the remainder of the assessment: While ongoing assessment is important, the rhythm strip shows atrial flutter, a potentially unstable arrhythmia, and the client is experiencing symptoms (nausea after breakfast) which could suggest compromised cardiac output. Completing the remainder assessment delays the necessary intervention.
B. Obtain an order for adenosine IV: Adenosine is typically used for stable supraventricular tachycardia (SVT), not for atrial flutter, as it may not terminate the rhythm. It may slow conduction enough to better visualize flutter waves, but initiating it without a provider's order or further evaluation is inappropriate.
C. Notify the physician of the symptoms: The client’s rhythm strip shows atrial flutter with a rapid ventricular response and the patient is experiencing nausea, which could indicate decreased perfusion or early decompensation. Immediately notifying the provider is the safest and most appropriate action for further evaluation and treatment planning.
D. Administer the prescribed ACE inhibitor: ACE inhibitors are used for blood pressure control or heart failure management, not for acute rhythm disturbances. Administering it would not address the current rhythm or symptoms and could worsen hypotension if cardiac output is compromised.

Correct Answer is C
Explanation
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. the heart rate is greater than 100 bpm in sinus tachycardia: Normal Sinus Rhythm is characterized by a heart rate between 60 and 100 beats per minute (bpm). Sinus tachycardia is defined as a sinus rhythm with a heart rate exceeding 100 beats per minute. The rhythm remains regular, with each P wave followed by a QRS complex, but the rate is significantly faster than normal sinus rhythm.
B. more p waves are present than QRS complexes: In sinus tachycardia, the number of P waves and QRS complexes remains one-to-one, as each atrial impulse continues to be conducted to the ventricles. More P waves than QRS complexes typically suggest atrial flutter or other forms of AV dissociation.
C. the QRS complexes measure greater than 0.10: A widened QRS complex suggests a bundle branch block or ventricular rhythm, not sinus tachycardia. In sinus tachycardia, QRS complexes typically remain narrow, measuring less than 0.10 seconds unless an intraventricular conduction delay is present.
D. the rhythm is often irregular in sinus tachycardia: Sinus tachycardia is usually a regular rhythm with consistent R-R intervals. An irregular rhythm is more indicative of atrial fibrillation or sinus arrhythmia, not a defining characteristic of sinus tachycardia.
