BLS Assessment Quiz

Study Notes

BLS Assessment

Steps include checking responsiveness and breathing, shouting for help, assessing breathing and pulse, and defibrillation if necessary.

Check for Responsiveness and Breathing

Administer oxygen to patients experiencing acute cardiac symptoms.
Shake and shout for unresponsive individuals; for trauma, use touch and talk.
If the patient is unresponsive and not breathing, immediately seek help.

Shouting for Help

Activate the emergency response system.
Retrieve an AED if available.
Assign someone to activate emergency services while obtaining an AED.

Breathing and Pulse Assessment

Look for absent or abnormal breathing, focusing on chest movement.
Conduct pulse check alongside breathing assessment within 10 seconds.
If no pulse is detectable, commence CPR with chest compressions. If a pulse is present, provide rescue breaths every 5-6 seconds.

CPR Initiation

Begin CPR with chest compressions immediately after confirming no pulse for 10 seconds.
If a pulse is felt, provide rescue breathing and check pulse every 2 minutes.

Defibrillation

Check for shockable rhythm using an AED upon its arrival if no pulse is detected.
Administer shocks as prescribed, resuming CPR immediately after each shock.

Chest Compression Interruptions

Limit interruptions to no longer than 10 seconds, avoiding factors such as prolonged rhythm analysis or unnecessary movements.
Blood flow ceases to the brain and heart during interruptions.

Quality of Compressions

Compress the chest at least 2 inches deep at a rate of 110-120 compressions per minute while allowing complete chest recoil.
Change compressor every 2 minutes or sooner if fatigued to maintain effective CPR.

Primary Assessment Components

Evaluate Airway, Breathing, Circulation, Defibrillation, Disability, and Exposure (ABCDE).

Airway Management

Ensure the airway is patent; apply head tilt chin lift for unconscious patients.
Consider advanced airway interventions if needed, including intubation.

Breathing Support

Provide supplemental oxygen; for cardiac patients, deliver 100% oxygen.
Assess ventilation/effectiveness; ensure breaths allow chest rise and avoid excessive ventilations.

Circulation Evaluation

Conduct responsiveness and breathing check, calling for emergency assistance if necessary.
Palpate carotid/femoral pulse; initiate chest compressions if absent.

Disability Assessment

Quickly check neurologic function including responsiveness, level of consciousness, and pupil dilation.

Exposure and Physical Examination

Remove clothing to examine for trauma, bleeding, burns, or any unusual markings, including medical alert identifiers.

Secondary Assessment

Focus on differential diagnosis, gathering a focused patient history, and utilizing the SAMPLE acronym: Signs/symptoms, Allergies, Medications, Past medical history, Last meal, Events leading to the situation.

Causes of Cardiac Arrest (H's and T's)

Identify and treat conditions such as hypovolemia, hypoxia, acidosis, hypoglycemia, electrolyte imbalances, hypothermia, tension pneumothorax, thrombosis, cardiac tamponade, and toxins to manage underlying causes effectively.

Hypovolemia Symptoms and Treatment

Recognized by rapid heart rate and narrow QRS; treated with normal saline or lactated Ringer's bolus.

Hypoxia Symptoms and Treatment

Indicated by slow heart rate and cyanosis; addressed with airway management and supplemental oxygen.

Acidosis and Its Management

Identify by low amplitude QRS; manage with hyperventilation and sodium bicarbonate.

Hypoglycemia Recognition and Treatment

Presenting as altered level of consciousness and arrhythmias; treated with dextrose.

Electrolyte Imbalances (Hypo/Hyperkalemia)

Hypokalemia signs include flattened T waves; treat with magnesium. Hyperkalemia presents as peaked T waves and widened QRS; manage with calcium chloride, sodium bicarbonate, and insulin.

Hypothermia Recognition and Management

Symptoms include shivering and cold exposure; address with rewarming.

Tension Pneumothorax Detection and Treatment

Marked by chest asymmetry and absent breath sounds; requires immediate needle decompression.

Thrombotic Events

Symptoms of pulmonary embolism include rapid heart rate and narrow QRS; treatment involves fibrinolytics or embolectomy.

Cardiac Tamponade Management

Characterized by blood accumulation in the pericardial sac; treated with pericardiocentesis.

Toxin Overdose Symptoms and Management

Presenting with prolonged QT interval; treatment is based on the specific toxic agent involved.
