Question

question 10 of 25
identify this rhythm and immediate interventions. this patient does not have a pulse.

supraventricular tachycardia (svt), monitor patient.
pulseless electrical activity (pea): check for pulse, if no pulse call code blue, start cpr, anticipate giving epinephrine, consider hs & ts.
junctional tachycardia: check for a pulse, if no pulse, call a code, start cpr and defibrillate the patient, consider hs & ts.
pulseless electrical activity (pea): check for a pulse, if no pulse, call a code blue, start cpr, anticipate giving atropine, consider hs & ts.
sinus rhythm: monitor patient.

Explanation:

Analyze the ECG rhythm and clinical presentation

The ECG strip displays an organized rhythm with visible QRS complexes and regular intervals. However, the clinical prompt explicitly states: "This Patient does NOT have a pulse." Organized electrical activity on an ECG in the absence of a palpable pulse is the definition of Pulseless Electrical Activity (PEA).

Evaluate immediate interventions for PEA

According to Advanced Cardiac Life Support (ACLS) guidelines, the management of PEA includes:

1. Confirming pulselessness.
2. Activating emergency response (calling a code blue).
3. Initiating high-quality CPR immediately.
4. Administering epinephrine (1 mg IV/IO every 3–5 minutes).
5. Identifying and treating reversible causes (the H's and T's).

Defibrillation is not indicated for PEA (it is a non-shockable rhythm), and atropine is no longer recommended in the standard ACLS cardiac arrest algorithm.

Compare and select the correct option

• Option 1 (SVT) and Option 5 (Sinus Rhythm) are incorrect because the patient is pulseless.
• Option 3 is incorrect because it suggests defibrillation, which is contraindicated for non-shockable rhythms like PEA.
• Option 4 is incorrect because it recommends atropine instead of epinephrine.
• Option 2 correctly identifies the rhythm as PEA and outlines the appropriate ACLS interventions: check pulse, call code blue, start CPR, anticipate epinephrine, and consider H's & T's.

Answer:

• Supraventricular Tachycardia (SVT), monitor patient.
• Pulseless Electrical Activity (PEA): check for pulse, if no pulse call code blue, start CPR, anticipate giving epinephrine, consider H's & T's. (Correct answer)
• Junctional Tachycardia: check for a pulse, if no pulse, call a code, start CPR and defibrillate the patient, consider H's & T's.
• Pulseless Electrical Activity (PEA): check for a pulse, if no pulse, call a code blue, start CPR, anticipate giving Atropine, consider H's & T's.
• Sinus Rhythm: monitor patient.
