Question

1. the aed should be applied only to unresponsive patients with no:

a. significant medical problems
b. cardiac history
c. pulse
d. brain activity

1. __________ usually refers to a state of cardiac arrest despite an organized electrical complex.

a. asystole
b. pulseless electrical activity
c. ventricular fibrillation
d. ventricular tachycardia

1. the links in the chain of survival include all of the following except:

a. immediate high - quality cpr
b. als and postarrest care
c. administration of nitroglycerin
d. rapid defibrillation

1. defibrillation works best if it takes place within __________ minutes of the onset of cardiac arrest.

a. 2
b. 4
c. 6
d. 10
questions 41 - 45 are derived from the following scenario: at 0500, you respond to the home of a 76 - year - old man complaining of chest pain. on arrival, the patient states that he had been sleeping in the recliner all night due to indigestion. he also tells you he has taken two nitroglycerin tablets. he continues to have pain and reports trouble breathing.

1. your first priority is to:

a. apply an aed
b. provide high - flow oxygen
c. evaluate the need to administer a third nitroglycerin tablet
d. size - up the scene

1. his vital signs are as follows: respirations, 16 breaths/min; pulse, 98 beats/min; blood pressure, 92/76 mm hg. he is still complaining of chest pain. what actions should you take to intervene?

a. provide high - flow oxygen.
b. administer a third nitroglycerin tablet.
c. apply an aed.
d. begin chest compressions.

1. your patient suddenly becomes unresponsive. assessment reveals no breathing and no pulse. your partner begins chest compressions while you apply the aed. when operating an aed, what is the first step in the defibrillation sequence?

a. plug the pads connector to the aed.
b. apply the aed pads to the patients chest.
c. remove clothing from the patients chest.
d. turn on the aed.

1. after applying an aed to this patient, the aed states,

o shock advised.\ what is your next step of action?
a. load and transport the patient.
b. push to reanalyze.
c. perform cpr for 2 minutes, starting with chest compressions, then have the aed reanalyze.
d. consider termination.

Explanation:

For question 37: AED is used when there's no pulse (cardiac arrest). For question 38: Pulseless electrical activity is cardiac arrest with organized electrical complex. For question 39: Nitroglycerin administration isn't a standard chain - of - survival link. For question 40: Defibrillation best within 2 minutes. For question 41: Scene size - up is first. For question 42: High - flow oxygen for chest pain and trouble breathing. For question 43: First step in AED use is turning it on. For question 44: After "No shock advised", continue CPR for 2 minutes.

Answer:

1. C. pulse
2. B. Pulseless electrical activity
3. C. administration of nitroglycerin
4. A. 2
5. D. size - up the scene
6. A. Provide high - flow oxygen
7. D. Turn on the AED
8. C. Perform CPR for 2 minutes, starting with chest compressions, then have the AED reanalyze
