Chapter 40 Flashcards
(15 cards)
A field code runs most efficiently when:
- tracheal intubation is performed early
- a designated team leader is assigned
- the AED replaces manual defibrillation
-at least five paramedics are participating
a designated team leader is assigned
Which of the following interventions is emphasized the most in all AHA guidelines for emergency cardiac care since 2005?
- chest compressions
- Artifical ventilation
- defibrillation
- tracheal intubation
Chest compressions
Impedance threshold devices, such as the ResQPOD, function by:
- dilating the coronary arteries, which reduces cardiac afterload
- creating a vacuum in the chest, which increases blood flow to the heart.
- facilitating vasoconstriction, which maintains coronary perfusion pressure.
- increasing intrathoracic pressure, which reduces blood return to the heart.
creating a vacuum in the chest, which increases blood flow to the heart.
The paramedic should consider extending the resuscitation effort of a patient with refractory cardiac arrest if:
- return of spontaneous circulation of any duration occurred.
- ventricular fibrillation occurred at any point during the arrest.
- the cardiac arrest was caused by submersion in warm water
- the patient has no known significant past medical histor
return of spontaneous circulation of any duration occurred.
You are the team leader in the attempted resuscitation of an adult man in ventricular fibrillation. An advanced airway device has been inserted and vascular access has been obtained. As you observe the actions of your team members, you should ensure that:
- the person managing the airway delivers one breath every 3 to 5 seconds.
- no one person performs chest compressions for more than 5 minutes at a time.
- compressions are hard and fast, with full chest recoil between compressions.
- the patient is defibrillated one time every 60 seconds as necessary.
compressions are hard and fast, with full chest recoil between compressions.
Your partner returns with the AED as you are performing CPR on a 5-year-old child. As he opens the AED, he tells you that there are no pediatric pads, only adult pads. You should:
- continue two-rescuer CPR until a manual defibrillator is available.
- use the adult AED pads, but only provide a total of two defibrillations.
- tell him to resume one-rescuer CPR as you try to locate pediatric pads.
- instruct him to apply the adult pads as you continue one-rescuer CPR.
instruct him to apply the adult pads as you continue one-rescuer CPR.
You and your team are attempting to resuscitate a 45-year-old man who is in cardiac arrest. After 2 minutes, you assess his cardiac rhythm and determine that he is in asystole. After instructing your team to resume CPR, you should:
- perform endotracheal intubation and ventilate at a rate of 15 breaths/min.
- insert an advanced airway device and then resume cycles of CPR.
- administer 1 mg of epinephrine 1:10,000 after obtaining vascular access.
- establish IV or IO access and administer 1 mg of atropine sulfate rapidly.
administer 1 mg of epinephrine 1:10,000 after obtaining vascular access.
What is the current recommendation for the use of epinephrine for patients with ventricular fibrillation or pulseless ventricular tachycardia?
- Higher doses of epinephrine should be used for these patients.
- Epinephrine should be administered after the second shock
- Epinephrine should not be given within the first 10 minutes.
- Epinephrine is not recommended for this subset of patients.
- Epinephrine should be administered after the second shock
Your assessment of a 68-year-old woman reveals an organized cardiac rhythm at a rate of 80 beats/min and an absent carotid pulse. Treatment for this patient may include:
- hyperventilation
- naloxone administration
- cardiac pacing
- epinephrine
Epinephrine
After determining that an unresponsive adult patient is not breathing, you should:
- perform a finger sweep of the patient’s mouth to remove any debris.
- reposition the patient’s airway and reassess for breathing.
- assess for a carotid pulse for no longer than 10 seconds.
- give two rescue breaths that make the chest visibly rise
assess for a carotid pulse for no longer than 10 seconds.
When responding to a field code with a five-person team, what is one of the roles of the ventilator?
- To assist with the application of mechanical chest compressions
- To perform the initial ECG analysis
- To suction the patient, as necessary
- To establish IV/IO access
To suction the patient, as necessary
Which of the following should occur when integrating a mechanical CPR device into your resuscitation attempt of an adult patient?
- One breath should be given every 6 seconds until an advanced airway is inserted.
- Compressions should be continuous after an advanced airway device is inserted.
- The compression rate should be set to deliver at least 80 compressions per minute.
- Compression depth should be at least 1.5 inches after the device is applied.
Compressions should be continuous after an advanced airway device is inserted.
In addition to high-quality CPR, which of the following interventions has clearly made a positive and measurable difference in survival from sudden cardiac arrest?
- defibrillation
- IV fluid boluses
- epinephrine therapy
- tracheal intubation
Defibrillation
Defibrillation of a patient who is in asystole is detrimental to the patient because it:
- has been shown to render epinephrine ineffective.
- stops the cardiac cells from spontaneously depolarizing.
- causes an unnecessary interruption in chest compressions.
- makes ruling out underlying causes impossible.
causes an unnecessary interruption in chest compressions.
How does CPR change after an advanced airway device is inserted?
- Ventilations should be faster after the device is inserted.
- Ventilations should be asynchronous with chest compressions.
- One breath should be delivered every 10 to 12 seconds.
- Cycles of 30 compressions and 2 breaths should be delivered.
Ventilations should be asynchronous with chest compressions.
