Chapter 13 BLS Resuscitation

If your patient has no pulse, you should immediately __________. rule out airway obstruction begin ventilations check for breathing begin chest compressions

Respiratory arrest usually occurs before cardiac arrest in __________. adults children the elderly all patients

Which of the following is true of infants and children? They usually go into respiratory arrest due to cardiac arrest. They can store oxygen more efficiently than adults. They require less-frequent ventilations than adults. They consume oxygen much faster than adults.

Which of the following statements regarding CPR is correct? CPR corrects most causes of cardiac arrest. CPR temporarily provides minimal circulation and ventilation. CPR often prevents the need for advanced life support. CPR should be discontinued once an AED is available.

What is the correct management of a conscious infant who is choking? Back blows and chest thrusts Chest compressions Abdominal thrusts Blind finger sweep

After ________ minutes without oxygen, permanent brain damage is possible. 1 to 2 4 to 6 2 to 3 7

You and your partner arrive at the side of a 60-year-old woman who collapsed about 7 minutes ago. She is unresponsive, apneic, and pulseless. You should: begin CPR and apply the AED as soon as it is available. immediately apply the AED and analyze her cardiac rhythm. begin CPR at a compression to ventilation ratio of 15:2. apply the AED if there is no response after 10 cycles of CPR.

Which of the following statements regarding the use of an AED in children is correct? If the patient is younger than 1 year of age, an AED is preferred over a manual defibrillator. AEDs are only effective in pediatric patients if severe trauma is the cause of their cardiac arrest. AED use in children up to 8 years of age involves pediatric pads and an energy reducer. AEDs are not used in pediatric patients because they do not experience ventricular fibrillation.

A patient should be placed in the recovery position when he or she: is semiconscious, injured, and breathing adequately. has experienced trauma but is breathing effectively. is unresponsive, uninjured, and breathing adequately. has a pulse but is unresponsive and breathing shallowly.

Which of the following maneuvers should be used to open a patient's airway when a spinal injury is suspected? Jaw-thrust Tongue-jaw lift Head tilt-neck lift Head tilt-chin lift

When ventilating an apneic adult with a bag-valve mask, you should deliver each breath: over a period of about 2 to 3 seconds. while watching for adequate chest rise. with a tidal volume of about 500 mL. quickly to ensure adequate ventilation.

To ensure that you will deliver the appropriate number of chest compressions during one-rescuer adult CPR, you should compress the patient's chest at a rate of: 80 to 100 compressions per minute. at least 120 compressions per minute. 100 to 120 compressions per minute. no greater than 100 compressions per minute.

In two-rescuer adult CPR, you should deliver a compression to ventilation ratio of: 5:1. 5:2. 15:2. 30:2.

After an advanced airway device has been inserted during two-rescuer CPR, you should: pause compressions to deliver ventilations. deliver one rescue breath every 6 seconds. decrease the compression rate to about 80 per minute. increase rescue breathing to a rate of 14 breaths/min.

The main benefit of using a mechanical device for chest compressions is: the minimal training required to correctly operate the devices. the elimination of rescuer fatigue that results from manual compressions. the elimination of the need to place a firm, flat device under the patient. its ability to be used with any patient, regardless of age, weight, or body size.

Which of the following is considered an obvious sign of death and would not require the initiation of CPR? Dependent blood pooling Pulselessness and apnea Agonal respiratory effort Severe cyanosis to the face

Which of the following is NOT an indication to stop CPR once you have started? Pulse and respirations return You are physically exhausted. A physician directs you to do so. Care is transferred to a bystander

Your initial attempt to ventilate an unresponsive, apneic 30-year-old man is met with resistance and you do not see the chest rise. Your second ventilation attempt is also unsuccessful. You should: suction the oropharynx. perform a blind finger sweep. perform 30 chest compressions. ventilate again with greater force.

A team of EMTs and paramedics are attempting to resuscitate a man who is in cardiac arrest while his wife and son are present. Which of the following should occur during the resuscitation attempt? One EMT should update the family on the interventions that have been performed and how the patient has responded. Each member of the resuscitation team should update the family at various intervals throughout the attempt. Communication with the family should be minimal until the final outcome of the resuscitation attempt is known. A law enforcement officer should prepare the family for the patient's death and contact the funeral home.

CPR is in progress on a pregnant woman. Shortly after manually displacing her uterus to the left, return of spontaneous circulation occurs. Which of the following would MOST likely explain this? Select one: A. Displacement of her uterus caused blood to flow backward, which increased blood flow to her heart. B. Displacement of her uterus allowed her lungs to expand more fully, which restored her pulse. C. Pressure was relieved from her aorta and vena cava, which improved chest compression effectiveness. D. Increased blood flow to her heart caused her ventricles to stop fibrillating, which restored her pulse.

The impedance threshold device (ITD) may improve circulation during active compression-decompression CPR by: Select one: A. maintaining increased intrathoracic pressure during the downward stroke of each chest compression, which forces more blood from both of the ventricles. B. drawing all of the air out of the lungs in between chest compressions, which causes positive intrathoracic pressure and a reduction of blood return to the right side of the heart. C. maximizing the amount of air in the lungs following chest recoil, which hyperinflates the lungs and forces more blood from the ventricle during each compression. D. limiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling.
