Section 1: Basic Life Support (BLS) Review

These questions assess your fundamental knowledge of BLS, a crucial prerequisite for ACLS.

Question 1: What are the steps in performing high-quality CPR on an adult victim of sudden cardiac arrest (SCA)?

Answer 1: High-quality CPR includes:

• Checking for responsiveness and pulse: Assess the victim's responsiveness and check for a carotid pulse for no more than 10 seconds.
• Activating the emergency response system (EMS): Call for help immediately.
• Chest compressions: Perform chest compressions at a rate of 100-120 compressions per minute, with a depth of at least 2 inches (5 cm), allowing for complete chest recoil after each compression. Minimize interruptions.
• Airway: Open the airway using the head-tilt-chin-lift maneuver.
• Breathing: Give 2 rescue breaths after every 30 chest compressions. Ensure each breath takes 1 second to deliver and the chest visibly rises.
• Compression-to-ventilation ratio: Maintain a 30:2 compression-to-ventilation ratio.
• High-performance CPR: Focus on minimizing interruptions to chest compressions, ensuring adequate depth and rate.

Question 2: What are the signs and symptoms of respiratory distress?

Answer 2: Signs and symptoms of respiratory distress include:

• Increased respiratory rate: Rapid breathing (tachypnea)
• Use of accessory muscles: Visible effort in breathing, using muscles in the neck and chest.
• Retractions: Indrawing of the skin between the ribs or above the clavicles.
• Wheezing: A whistling sound during breathing.
• Cyanosis: Bluish discoloration of the skin and mucous membranes.
• Altered mental status: Confusion, lethargy, or unresponsiveness.
• Nasal flaring: Widening of the nostrils during breathing.

Question 3: Describe the proper technique for delivering rescue breaths.

Answer 3: Proper rescue breath delivery involves:

• Creating an airtight seal: Ensure a proper seal around the victim's mouth and nose to prevent air leakage.
• Delivering adequate breaths: Deliver breaths over 1 second, observing for chest rise.
• Avoid excessive ventilation: Overventilation can be harmful. Aim for visible chest rise without forceful breaths.
• Maintaining chest compressions: Minimize interruptions to chest compressions when delivering breaths.

Section 2: Cardiac Rhythms and Recognition

This section focuses on recognizing and interpreting common cardiac rhythms encountered in ACLS scenarios.

Question 4: Describe the characteristics of ventricular fibrillation (VF).

Answer 4: Ventricular fibrillation (VF) is characterized by:

• Chaotic, irregular waveforms: No discernible P waves, QRS complexes, or T waves.
• Absence of a pulse: VF is a pulseless rhythm.
• Rapid, disorganized electrical activity: The ventricles quiver ineffectively, preventing blood from being pumped.
• Immediate defibrillation required: VF is a life-threatening rhythm requiring immediate defibrillation.

Question 5: What are the characteristics of pulseless electrical activity (PEA)?

Answer 5: Pulseless electrical activity (PEA) is characterized by:

• Organized electrical activity: A discernible rhythm is present (e.g., sinus rhythm, bradycardia).
• Absence of a palpable pulse: Despite the organized electrical activity, no pulse is detected.
• Requires immediate advanced life support: PEA is a life-threatening condition requiring immediate advanced life support interventions.
• Underlying causes must be identified and treated: Treatment focuses on addressing the underlying cause of the PEA (e.g., hypovolemia, hypoxia, acidosis, tension pneumothorax, tamponade, thrombosis – the “H’s and T’s”).

Question 6: Differentiate between sinus tachycardia and atrial fibrillation.

Answer 6:

• Sinus Tachycardia: A normal sinus rhythm with a heart rate exceeding 100 beats per minute. P waves are present and consistent with the QRS complexes. It's often a compensatory response to stress, fever, or hypovolemia.
• Atrial Fibrillation (AFib): A chaotic atrial rhythm with absent P waves. The ventricular rate is irregular. It's characterized by rapid, disorganized atrial activity, leading to an irregular ventricular response. AFib can be life-threatening due to the risk of stroke and heart failure.

Section 3: ACLS Interventions and Algorithms

This section tests your understanding of ACLS algorithms and interventions.

Question 7: Outline the steps in the ACLS algorithm for managing VF/pulseless VT.

Answer 7: The ACLS algorithm for managing VF/pulseless VT includes:

1. Immediate defibrillation: Deliver a shock immediately if a defibrillator is available.
2. High-quality CPR: Continue high-quality CPR for 2 minutes after each shock.
3. Medication administration: Administer epinephrine followed by antiarrhythmic drugs (e.g., amiodarone) according to the algorithm.
4. Rhythm check: After each round of CPR and medication administration, assess the rhythm and repeat steps as needed.
5. Advanced airway management: Consider advanced airway management if needed.

Question 8: What are the common causes of PEA?

Answer 8: The common causes of PEA are often remembered by the mnemonic “H’s and T’s”:

• Hypovolemia: Low blood volume.
• Hypoxia: Low oxygen levels.
• Hydrogen ion (acidosis): Increased acidity in the blood.
• Hyperkalemia/Hypokalemia: Electrolyte imbalances (high or low potassium).
• Hypothermia: Low body temperature.
• Tension pneumothorax: Collapsed lung due to air pressure.
• Tamponade (cardiac): Fluid accumulation around the heart.
• Toxins: Poisoning.
• Thrombosis (pulmonary/coronary): Blood clot in the lungs or heart.

Question 9: Describe the role of epinephrine in ACLS.

Answer 9: Epinephrine is a crucial medication in ACLS, playing a vital role in:

• VF/pulseless VT: Increases myocardial contractility and heart rate, improving the effectiveness of defibrillation.
• PEA: Increases myocardial contractility and heart rate, potentially restoring spontaneous circulation.
• Cardiac arrest: Acts as a potent vasoconstrictor, improving blood pressure and perfusion.

Section 4: Advanced Airway Management

This section assesses your knowledge regarding advanced airway techniques.

Question 10: What are the indications for endotracheal intubation?

Answer 10: Indications for endotracheal intubation include:

• Apnea: Absence of breathing.
• Respiratory failure: Inability to maintain adequate ventilation.
• Severe hypoxemia: Life-threatening low blood oxygen levels.
• Inability to protect the airway: Risk of aspiration.
• Requirement for controlled ventilation: Need for mechanical ventilation.

Question 11: Briefly explain the steps involved in endotracheal intubation.

Answer 11: Endotracheal intubation involves:

1. Preoxygenation: Administering 100% oxygen.
2. Medication (optional): Administering sedatives and paralytics.
3. Positioning: Maintaining appropriate head and neck alignment.
4. Laryngoscopy: Visualizing the larynx using a laryngoscope.
5. Tube placement: Inserting the endotracheal tube into the trachea.
6. Confirmation: Confirming tube placement by auscultation, capnography, and chest rise.
7. Securement: Securing the tube in place.

Question 12: What are the potential complications of endotracheal intubation?

Answer 12: Potential complications of endotracheal intubation include:

• Esophageal intubation: Accidental placement of the tube in the esophagus.
• Trauma to the airway: Injury to the vocal cords, trachea, or other structures.
• Hypoxemia: Low blood oxygen levels.
• Infection: Risk of respiratory infection.
• Dental injury: Damage to the teeth.

Section 5: Post-Cardiac Arrest Care

This section covers the crucial aspects of post-cardiac arrest care.

Question 13: What is targeted temperature management (TTM)?

Answer 13: Targeted temperature management (TTM) involves cooling the body to a specific temperature range (typically 32-36°C) after cardiac arrest to reduce neurological damage and improve survival rates.

Question 14: What are the goals of post-cardiac arrest care?

Answer 14: The goals of post-cardiac arrest care include:

• Restoration of spontaneous circulation: Maintaining adequate blood flow and oxygen delivery.
• Neurological protection: Minimizing brain damage.
• Treatment of underlying causes: Addressing the root cause of cardiac arrest.
• Monitoring and support: Closely monitoring vital signs and providing supportive care.
