Question 1

``` H1). Which type of cardiac arrest is caused by conditions such as respiratory problems and​ shock? A. Agonal cardiac arrest B. Asphyxial cardiac arrest C. Sudden cardiac arrest D. Commotio cordis ```

Accepted Answer

B. Asphyxial cardiac arrest (Page 585) Asphyxial cardiac arrest implies that the heart has stopped pumping due to issues related to systemic hypoxia. Conditions like respiratory problems and​ shock, which lead to low oxygen levels in the​ blood, cause this type of cardiac arrest.

Question 2

H2). Which of the following patients is most likely to be in cardiac​ arrest? A. ​Unresponsive, agonal​ breathing, no carotid pulse B. ​Unresponsive, no​ breathing, carotid pulse of 40 per minute C. Responds to pain​ only, agonal​ breathing, no radial pulse D. ​Unresponsive, respiratory rate of 8 per​ minute, no radial pulse

Accepted Answer

A. ​Unresponsive, agonal​ breathing, no carotid pulse The three key features of a cardiac arrest patient are​ unresponsiveness, agonal or no​ breathing, and absence of a central pulse.

Question 3

``` H3). A​ "pit crew" approach is involved​ in: A. ​high-performance CPR. B. advanced life support. C. rapid defibrillation. D. emergency medical response ```

Accepted Answer

A​ "pit crew" approach is involved​ in: ​High-performance CPR involves a​ "pit crew," or highly​ choreographed, approach to resuscitation. In this type of​ CPR, rescuers position themselves for maximum efficiency and minimum interruption of​ high-quality CPR. Advanced life support involves EMT professionals specialized in providing specific ALS interventions who coordinate with the rest of the life support​ team, but the team​ doesn't provide advance life support in a pit crew approach. Emergency medical response in general may or may not involve this​ approach, and rapid defibrillation may be performed by a single rescuer.

Question 4

``` H4) Expect to perform​ one-rescuer CPR: A. under direct ALS supervision. B. if you are the first and only responder. C. in any emergency response situation. D. when lifting and moving patients. ```

Accepted Answer

B. if you are the first and only responder. If you are alone waiting for the arrival of an​ AED, as in a​ first-response situation, you may need to perform​ one-rescuer CPR. You should not expect to perform​ one-rescuer CPR in any emergency response​ situation, such as in situations involving​ high-performance CPR. You cannot expect to receive direct ALS supervision when performing CPR. CPR cannot be performed while lifting and moving patients.

Question 5

H5) The direction of the shock from a monophasic defibrillator​ is: A. dependent on the device settings. B. from positive to negative. C. dependent on the position of the pads. D. from negative to positive.

Accepted Answer

D. from negative to positive. Whereas a biphasic defibrillator sends a shock first in one direction between negative and positive and then in the​ other, the traditional monophasic defibrillator sends a single shock from the negative pad to the positive pad.

Question 6

``` H6) You are using the Zoll AutoPulse resuscitation system. An advanced airway is in place. What is the correct compression rate per​ minute? A. 80 B. 60 C. 75 D. 100 ```

Accepted Answer

D. 100 The correct compression rate when using the Zoll AutoPulse device is a continuous 100 per minute.

Question 7

``` H7) You are using the Zoll AutoPulse resuscitation system. An advanced airway is in place. What is the correct ventilation rate per​ minute? A. 8-10 B. 12-20 C. 20-30 D. 16-24 ```

Accepted Answer

A. 8-10 The correct ventilation rate when using the Zoll AutoPulse device is 810 per minute. (100 per minute)

Question 8

``` H8) Your patient is unresponsive and is not breathing. Your partner is calling for ALS backup. Which of the following airway adjuncts is​ appropriate? A. ​Small-volume nebulizer B. Pocket mask C. ​Bag-valve mask D. Oropharyngeal airway ```

Accepted Answer

D. Oropharyngeal airway An oropharyngeal or nasopharyngeal airway should be used for the​ unresponsive, apneic patient. The​ BVM, pocket​ mask, and nebulizer are not airway adjuncts.

Question 9

``` H9) Which of the following must the EMT do while the AED analyzes the​ rhythm? A. Continue​ high-quality CPR B. Check for a pulse C. Stay clear D. Ventilate at a rate of 12 per minute ```

Accepted Answer

1. C. Stay clear The rescuer must stay clear and stop contact with the patient when the AED analyzes the rhythm. Continuing contact with the patient can interfere with the​ AED's ability to identify a shockable rhythm.

Question 10

``` H10) In a cardiac arrest​ situation, in addition to reanalyzing with the AED every 2​ minutes, during the​ "clear" interval you​ should: A. check the pulse at the wrist. B. assess the blood pressure. C. change compressors. D. contact medical control. ```

Accepted Answer

C. change compressors. No provider should compress the chest for more than two minutes. Fatigue sets in​ (even if it is not​ felt), and the quality of chest compressions decreases.​ Therefore, during each analysis by the​ AED, compressors should be switched.

Question 11

H11) Before you press the shock button on the​ AED, you should call​ "Clear!" and do which of the​ following? A. Call 911 B. Check the pulse again C. Scan the patient from head to toe to ensure that no one is touching him D. Give two breaths

Accepted Answer

C. Scan the patient from head to toe to ensure that no one is touching him Before​ shocking, you should scan the patient from head to toe to ensure that no one is touching the patient or any conductive material that the patient is touching. You should not delay for breathing or pulse checks.

Question 12

H12) Under which circumstance may you cease resuscitation​ efforts? A. No other trained rescuers have arrived. B. The patient is not breathing. C. A bystander with first responder training can take over. D. Spontaneous circulation occurs.

Accepted Answer

D. Spontaneous circulation occurs. Once you have started​ resuscitation, you may cease to provide resuscitation if spontaneous circulation​ occurs, but you should continue to provide rescue breathing as needed.

Question 13

H13) Which statement is​ correct? A. Resuscitation efforts must continue until ALS has provided an advanced airway intervention. B. If you are​ exhausted, a bystander may take over if you give that person verbal instructions. C. You may cease resuscitation efforts if you are too exhausted to continue. D. Resuscitation efforts must continue until spontaneous circulation and breathing both occur.

Accepted Answer

C. You may cease resuscitation efforts if you are too exhausted to continue. You may cease resuscitation efforts if you are too exhausted to continue. You cannot turn over resuscitation efforts to a responder with less training than you. Resuscitation efforts may cease if spontaneous circulation​ occurs, but you should provide rescue breathing as needed. Resuscitation efforts do not necessarily need to continue until ALS provides an advanced airway intervention.

Question 14

``` H14) In which of the following situations should an AED be immediately attached and​ deployed? A. A patient with an implanted pacemaker B. A patient touching metal C. A provider touching a patient D. A patient lying in water ```

Accepted Answer

A. A patient with an implanted pacemaker Safety hazards that would delay defibrillation include​ someone's touching the​ patient, the​ patient's being wet or in​ water, or the​ patient's touching metal. Implanted pacemakers can cause impedance to defibrillation​ (and pads should be offset to avoid​ them), but an AED can be used safely in that situation.

Question 15

``` H15) A team has just rescued several people from the ocean after their boat capsized. You are working on a patient in cardiac arrest. Which type of defibrillator would be best for you to use in this​ situation? A. ​Public-access AED B. Manual defibrillator C. Monophasic defibrillator D. Biphasic defibrillator ```

Accepted Answer

D. Biphasic defibrillator When caring for a wet patient in cardiac arrest who needs​ defibrillation, a modern biphasic defibrillator is unlikely to cause a rescuer significant harm.

Question 16

PT1). As you arrive for a patient in cardiac​ arrest, bystanders are analyzing the patient with an AED. You​ should: A. turn off the AED and check for a pulse. B. allow the AED to shock before you take over care. C. stay back until bystanders transfer care to you. D. remove the AED and apply your own.

Accepted Answer

B. allow the AED to shock before you take over care.

Question 17

PT2). For both the Lucas and Zoll AutoPulse CPR​ devices, you would take Standard Precautions​ and: A. close the Lifeband over the​ patient's chest. B. ensure CPR is in progress and effective. C. apply the stabilization strap. D. position the pressure pad so that it touches the chest.

Accepted Answer

B. ensure CPR is in progress and effective.

Question 18

``` PT3). If you are in doubt as to when or whether to terminate resuscitation​ efforts, seek the advice​ of: A. another EMT. B. a family member of the patient. C. a physician. D. an ALS provider. ```

Accepted Answer

C. a physician.

Question 19

PT4). If you turn resuscitation efforts for a patient over to another​ rescuer, this person must be trained to which level of​ proficiency? A. The level of an ALS provider B. The highest possible level C. The same level as or a greater level than you D. The level of a physician

Accepted Answer

C. The same level as or a greater level than you

Question 20

PT5). Which of the following is not one of the links in the chain of​ survival? A. Rehabilitation B. Immediate recognition and activation of the emergency response system C. Immediate​ high-quality CPR D. Rapid defibrillation

Accepted Answer

A. Rehabilitation

``` PT6) Delivery of an electrical shock to restore a normal heart rhythm most directly affects which of the​ following? A. Electrical function in the heart B. Blood pressure C. Peripheral pulses D. Blood circulation ```

Accepted Answer

A. Electrical function in the heart

Question 22

``` PT7) Which of the following would not be corrected by​ defibrillation? A. Asystole B. Dysrhythmia C. Ventricular tachycardia D. Ventricular fibrillation ```

Accepted Answer

A. Asystole
