BLS for Healthcare Providers Flashcards

What is the recommended compression-to-ventilation ratio for single-rescuer adult CPR in the BLS for Healthcare Providers course?

Answer: 30:2

The 30:2 ratio is the standard for single-rescuer adult CPR, minimizing interruptions to compressions while providing adequate ventilation.

In the BLS for Healthcare Providers course, what is the correct compression depth for adult CPR?

Answer: At least 2 inches but no more than 2.4 inches

AHA guidelines recommend at least 2 inches (5 cm) but no more than 2.4 inches (6 cm) for adult chest compressions to ensure adequate perfusion without injury.

During two-rescuer CPR for an adult patient, what should the compressor do while the ventilator delivers breaths?

Answer: Pause compressions for 2 seconds

In two-rescuer adult CPR, compressions should pause briefly (less than 10 seconds) to allow effective ventilations to be delivered.

What is the recommended compression rate for adult CPR in the BLS for Healthcare Providers guidelines?

Answer: 100-120 compressions per minute

The AHA recommends 100-120 compressions per minute for adult CPR to optimize cardiac output and perfusion pressure.

When should a healthcare provider check for a carotid pulse during the BLS algorithm?

Answer: Before starting CPR if the patient is unresponsive and not breathing normally

Healthcare providers should check the carotid pulse for no more than 10 seconds if a patient is unresponsive and not breathing normally before beginning CPR.

What does the term 'high-quality CPR' include according to BLS for Healthcare Providers standards?

Answer: Rate 100-120/min, depth ≥2 in, full recoil, minimal interruptions, avoid hyperventilation

High-quality CPR encompasses the correct rate, depth, full chest recoil, minimal interruptions, and avoiding excessive ventilation.

In the BLS healthcare provider algorithm, after delivering a shock with an AED, the rescuer should immediately:

Answer: Resume CPR starting with chest compressions

Immediately after an AED shock, CPR should resume starting with chest compressions without checking the pulse first.

When two rescuers perform CPR on an adult, how often should they switch roles?

Answer: Every 2 minutes

Rescuers should switch roles every 2 minutes (at each rhythm check) to prevent compressor fatigue and maintain compression quality.

What is the correct hand position for adult chest compressions?

Answer: Two hands on the lower half of the sternum

Both hands should be placed on the lower half of the sternum (not on the xiphoid process) to deliver effective compressions.

For an adult with an advanced airway in place during CPR, ventilations should be delivered at what rate?

Answer: Every 6 seconds (10 breaths/min)

With an advanced airway, give one breath every 6 seconds (10 breaths/min) without pausing compressions.

What is the preferred method of opening the airway in a patient with no suspected cervical spine injury?

Answer: Head-tilt chin-lift maneuver

The head-tilt chin-lift is the preferred technique for opening the airway when no spinal injury is suspected.

Which of the following rhythms is shockable and would prompt AED use?

Answer: Ventricular fibrillation (VF)

Ventricular fibrillation is a shockable rhythm. The AED is designed to detect and deliver shocks for VF and pulseless ventricular tachycardia.

What is 'chest recoil' and why is it important in CPR?

Answer: Allowing the chest to fully return to its natural position after each compression; it allows venous return and cardiac refilling

Full chest recoil allows negative intrathoracic pressure to draw venous blood back to the heart, enabling effective cardiac output.

In the BLS algorithm, what should be done when the AED indicates 'no shock advised'?

Answer: Immediately resume CPR starting with chest compressions

If the AED advises no shock, immediately resume CPR with chest compressions and continue the algorithm.

What is the maximum recommended time to pause compressions for any intervention during CPR?

Answer: 10 seconds

Interruptions to chest compressions should not exceed 10 seconds to maintain coronary and cerebral perfusion pressure.

Which of the following best describes the 'CPR fraction' or 'chest compression fraction'?

Answer: The proportion of resuscitation time spent performing chest compressions

CPR fraction (chest compression fraction) is the proportion of total resuscitation time during which chest compressions are being performed; a higher fraction is associated with better outcomes.

During mouth-to-mask ventilation in adult CPR, each breath should be delivered over approximately:

Answer: 1 second

Each rescue breath should be delivered over 1 second, sufficient to produce visible chest rise without causing gastric inflation.

A healthcare provider finds an unresponsive adult. After confirming no normal breathing and no pulse, what is the FIRST action?

Answer: Begin chest compressions

For a witnessed cardiac arrest with another rescuer present, begin chest compressions immediately while a second rescuer activates EMS and retrieves an AED.

What does 'ROSC' stand for in the context of advanced cardiac life support and BLS?

Answer: Return Of Spontaneous Circulation

ROSC stands for Return of Spontaneous Circulation, indicating the heart has resumed beating effectively on its own.

In BLS for Healthcare Providers, what is the preferred airway management device when bag-valve-mask ventilation is being used?

Answer: Oropharyngeal airway (OPA) in unconscious patients without a gag reflex

An oropharyngeal airway (OPA) is used in unconscious patients without a gag reflex to maintain airway patency during BVM ventilation.
