A patient whose artificial pacemaker has failed would MOST likely
experience:
A) weakness and bradycardia.
B) hypertension and a headache.
C) irreversible ventricular fibrillation.
D) dizziness and excessive tachycardia.
..................ANSWER.....A) weakness and bradycardia.
Feedback :
An artificial pacemaker is implanted in a person whose own cardiac
electrical conduction system cannot maintain a regular rhythm and rate.
If a pacemaker stops working, as when the battery wears out or an
internal lead becomes detached, the patient often experiences syncope,
dizziness, or weakness because of an excessively slow heart rate
(bradycardia). The pulse rate is typically less than 60 beats/min because
the heart is beating without the stimulus of the pacemaker and without
regulation of its own electrical conduction system, which may be

damaged. In these circumstances, the heart tends to assume a fixed slow
rate that may not be fast enough to maintain adequate cardiac output. In
some cases, the patient's heart rate may be so low that he or she becomes
hypotensive.
You are treating a 60-year-old man in cardiac arrest. After delivering a
shock with the AED and performing CPR for 2 minutes, you achieve
return of spontaneous circulation. Your next action should be to:
A) provide rapid transport to the hospital.
B) reanalyze his rhythm for confirmation.
C) assess his airway and ventilatory status.
D) remove the AED and apply 100% oxygen.
..................ANSWER.....C) assess his airway and ventilatory status.
Feedback :
If return of spontaneous circulation (ROSC) occurs (eg, a palpable pulse
is restored), your first action should be to reassess the patient's airway
and ventilatory status. If the patient remains apneic, continue rescue
breathing. If the patient is breathing adequately, administer supplemental
oxygen in a concentration that is sufficient to maintain an oxygen
saturation that is greater than 94%. After reassessing the airway and
breathing, and treating the patient accordingly, you should prepare for
immediate transport. Because of the high risk that cardiac arrest can
recur following resuscitation, you should not remove the AED pads;
simply turn the AED off instead. Analysis of the patient's cardiac rhythm
is not indicated because he now has a pulse.

You arrive at the scene shortly after a 55-year-old man collapsed. Two
bystanders are performing CPR. Your FIRST action should be to:
A) attach the AED and analyze his cardiac rhythm.
B) check the effectiveness of the CPR in progress.
C) insert an oropharyngeal airway and continue CPR.
D) stop CPR so you can assess breathing and pulse.
..................ANSWER.....D) stop CPR so you can assess breathing and
pulse.
Feedback :
Upon arriving at a scene where bystander CPR is in progress, you must
first confirm that the patient is indeed apneic and pulseless and needs
CPR. Bystanders who are not properly trained often perform CPR on
patients who do not need it. After confirming cardiac arrest, you should
resume CPR and attach the AED as soon as possible.
