questions Best Rated A+
1. You find an unresponsive patient who is not breathing. After activating the
emergency response system, you determine that there is no pulse. What is your next
action?
Open the airway with a head tilt-chin lift.
Administer epinephrine at a dose of 1 mg/kg.
Deliver 2 rescue breaths each over 1 second.
Start chest compressions at a rate of at least 100/min. - ANSWERS--Start chest
compressions at a rate of at least 100/min.
2. You are evaluating a 58-year-old man with chest pain. The blood pressure is
92/50 mm Hg, the heart rate is 92/min, the nonlabored respiratory rate is 14
breaths/min, and the pulse oximetry reading is 97%. What assessment step is most
important now?
PETCO2
Chest x-ray
Laboratory testing
Obtaining a 12-lead ECG - ANSWERS--Obtaining a 12-lead ECG
,3. What is the preferred method of access for epinephrine administration during
cardiac arrest in most patients?
Intraosseous
Endotracheal
Central intravenous
Peripheral intravenous - ANSWERS--Peripheral intravenous
4. An activated AED does not promptly analyze the rhythm. What is your next
action?
Begin chest compressions.
Discontinue the resuscitation attempt.
Check all AED connections and reanalyze.
Rotate AED electrodes to an alternate position. - ANSWERS--Begin chest
compressions.
5. You have completed 2 minutes of CPR. The ECG monitor displays the lead II
rhythm below, and the patient has no pulse. Another member of your team resumes
chest compressions, and an IV is in place. What management step is your next
priority?
Give 0.5 mg of atropine.
Insert an advanced airway.
Administer 1 mg of epinephrine.
Administer a dopamine infusion. - ANSWERS--Administer 1 mg of epinephrine.
6. During a pause in CPR, you see this lead II ECG rhythm on the monitor. The
patient has no pulse. What is the next action?
Establish vascular access.
Obtain the patient's history.
Resume chest compressions.
Terminate the resuscitative effort. - ANSWERS--Resume chest compressions.
7. What is a common but sometimes fatal mistake in cardiac arrest management?
Failure to obtain vascular access
Prolonged periods of no ventilations
Failure to perform endotracheal intubation
Prolonged interruptions in chest compressions - ANSWERS--Prolonged interruptions
in chest compressions
8. Which action is a component of high-quality chest compressions?
Allowing complete chest recoil
Chest compressions without ventilation
60 to 100 compressions per minute with a 15:2 ratio
Uninterrupted compressions at a depth of 11⁄2 inches - ANSWERS--Allowing
complete chest recoil
, 9. Which action increases the chance of successful conversion of ventricular
fibrillation?
Pausing chest compressions immediately after a defibrillation attempt
Administering 4 quick ventilations immediately before a defibrillation attempt
Using manual defibrillator paddles with light pressure against the chest
Providing quality compressions immediately before a defibrillation attempt -
ANSWERS--Providing quality compressions immediately before a defibrillation
attempt
10. Which situation BEST describes pulseless electrical activity?
Asystole without a pulse
Sinus rhythm without a pulse
Torsades de pointes with a pulse
Ventricular tachycardia with a pulse - ANSWERS--Sinus rhythm without a pulse
11. What is the BEST strategy for performing high-quality CPR on a patient with an
advanced airway in place?
Provide compressions and ventilations with a 15:2 ratio.
Provide compressions and ventilations with a 30:2 ratio.
Provide a single ventilation every 6 seconds during the compression pause.
Provide continuous chest compressions without pauses and 10 ventilations per
minute. - ANSWERS--Provide continuous chest compressions without pauses and
10 ventilations per minute.
12. Three minutes after witnessing a cardiac arrest, one member of your team
inserts an endotracheal tube while another performs continuous chest compressions.
During subsequent ventilation, you notice the presence of a waveform on the
capnography screen and a PETCO2 level of 8 mm Hg. What is the significance of
this finding?
Chest compressions may not be effective.
The endotracheal tube is no longer in the trachea.
The patient meets the criteria for termination of efforts.
The team is ventilating the patient too often (hyperventilation). - ANSWERS--Chest
compressions may not be effective.
13. The use of quantitative capnography in intubated patients:
allows for monitoring of CPR quality.
measures oxygen levels at the alveoli level.
determines inspired carbon dioxide relating to cardiac output.
detects electrolyte abnormalities early in code management. - ANSWERS--allows for
monitoring of CPR quality.
14. For the past 25 minutes, an EMS crew has attempted resuscitation of a patient
who originally presented in ventricular fibrillation. After the first shock, the ECG
