DETAILED ANSWERS (VERIFIED ANSWERS) |ALREADY

GRADED A

• 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 - ANSWER- Allowing complete chest recoil

• 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 - ANSWER- Providing quality compressions immediately before a defibrillation attempt

• 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 - ANSWER- Sinus rhythm without a pulse

• 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.

• ANSWER- Provide continuous chest compressions without pauses and 10 ventilations

per minute.

• Three minutes after witnessing a cardiac arrest, one member of your team inserts an

endotracheal tube while another performs continuous chest compressions. During 1 / 3

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). - ANSWER- 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. - ANSWER- allows for monitoring of CPR quality.

• 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 screen displayed asystole, which has persisted despite 2 doses of epinephrine, a fluid bolus, and high-quality CPR. What is your next treatment?

Apply a transcutaneous pacemaker.Administer 1 mg of intravenous atropine.Administer 40 units of intravenous vasopressin.Consider terminating resuscitative efforts after consulting medical control. - ANSWER- Consider terminating resuscitative efforts after consulting medical control.

• Which is a safe and effective practice within the defibrillation sequence?

Stop chest compressions as you charge the defibrillator.Be sure oxygen is not blowing over the patient's chest during the shock.Assess for the presence of a pulse immediately after the shock.Commandingly announce "clear" after you deliver the defibrillation shock. - ANSWER- Be sure oxygen is not blowing over the patient's chest during the shock.

• During your assessment, your patient suddenly loses consciousness. After calling for

help and determining that the patient is not breathing, you are unsure whether the patient has a pulse. What is your next action?

Leave and get an AED.Begin chest compressions.Deliver 2 quick ventilations.Check the patient's mouth for the presence of a foreign body. - ANSWER- Begin chest compressions.

• What is an advantage of using hands-free defibrillation pads instead of defibrillation

paddles?

Hands-free pads deliver more energy than paddles.Hands-free pads increase electrical arc.Hands-free pads allow for a more rapid defibrillation.Hands-free pads have universal adaptors that can work with any machine. - ANSWER- Hands-free pads allow for a more rapid defibrillation.

• What action is recommended to help minimize interruptions in chest compressions

during CPR?

Continue CPR while charging the defibrillator.Perform pulse checks immediately after defibrillation.Administer IV medications only when delivering breaths.Continue to use an AED even after the arrival of a manual defibrillator. - ANSWER- Continue CPR while charging the defibrillator.

• Which action is included in the BLS Survey?

Early defibrillation Advanced airway management Rapid medication administration Preparation for therapeutic hypothermia - ANSWER- Early defibrillation

• Which drug and dose are recommended for the management of a patient in

refractory ventricular fibrillation?

Atropine 2 mg Amiodarone 300 mg Vasopressin 1 mg/kg Dopamine 2 mg/kg per minute - ANSWER- Amiodarone 300 mg

• What is the appropriate interval for an interruption in chest compressions?

10 seconds or less 10 to 15 seconds 15 to 20 seconds Interruptions are never acceptable - ANSWER- 10 seconds or less

• 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.
