Advanced Cardiovascular Life Support (ACLS) Practice Exam

In the case of a patient in pulseless electrical activity (PEA) after initial resuscitation efforts, the appropriate action is to continue CPR and reassess the situation regularly. PEA is characterized by the presence of electrical activity on the ECG without an accompanying pulse, indicating that the heart is not effectively pumping blood.

Continuing CPR is crucial because it helps maintain blood flow to vital organs and increases the chances of restoring a perfusing rhythm. Recognizing that PEA often has reversible causes, ongoing CPR allows for time to identify and address these underlying issues, such as hypovolemia, hypoxia, acidosis, or electrolyte imbalances, which can be effectively treated.

Regular reassessment is important to monitor any changes in the patient's condition, allowing healthcare providers the opportunity to adapt their interventions as necessary, whether by administering medications, performing advanced airway management, or considering other treatments.

The other options provided do not align with current ACLS guidelines for managing PEA. Defibrillation is only indicated for shockable rhythms such as ventricular fibrillation or pulseless ventricular tachycardia. Administering nitroglycerin would not be appropriate in a situation where the patient has no pulse, as it is used primarily to relieve ang
