SRTC Quiz Chapter 21

Blunt and penetrating injuries can damage chambers of the heart or cause conditions like:

• ventricular fibrillation.

• pericardial tamponade.

• ventricular tachycardia.

• asphyxial cardiac arrest.

You are on the scene of a 68-year-old male patient complaining of severe chest pain for the last 20 minutes. He has a previous history of myocardial infarction and states it feels "just like the last time." You have applied oxygen and assisted him in administering aspirin and nitroglycerin with no reduction in the chest pain. Your nearest facility is 5 minutes away, a Level III Trauma Center is 10 minutes away, and a hospital with cardiac catheterization capabilities is 20 minutes away. The patient is requesting to be transported to his cardiologist's hospital, which is 30 minutes away. Which hospital is the best destination?

• The trauma center

• The nearest hospital with cardiac catheterization

• The nearest facility

• The hospital the patient requests

What does ventricular fibrillation do?

• Initiates commotio cordis

• Causes asphyxial cardiac arrest

• Prevents the heart muscle from contracting normally

• Forces the heartbeat to become quite rapid

Once an EMT has begun resuscitative efforts, when may the EMT cease those efforts?

• Spontaneous circulation and breathing occur.

• No other rescuer is available to relieve the EMT.

• The patient has no pulse after 1 minute.

• The EMT's partner gives the order to cease.

Which of the following should NOT be done during defibrillation?

• Shaving the chest before placing the defibrillation pads to improve contact

• Continued ventilation during the analysis phase to prevent hypoxia

• Pressing the defibrillation pads firmly to the chest to ensure good contact

• Performing CPR while the AED is being attached

You are on the scene of a 65-year-old female patient in cardiac arrest. CPR is in progress and the AED has been applied. The AED advises shock. After defibrillating the patient, what is your next intervention?

• Continue CPR

• Place in the recovery position

• Insert a Combitube

• Check for a pulse

You are the first on the scene of a 72-year-old patient in cardiac arrest. You have your medical supply kit, oxygen, and an AED. At least 4 to 5 minutes of high-quality CPR has been provided by the police officer who arrived before you. You have confirmed an open airway, apnea, and pulselessness. Which of the following should you do next?

• Perform bag-valve mask ventilations with supplemental oxygen for 30 seconds before applying the defibrillator pads.

• Perform one-rescuer CPR until additional personnel arrive.

• Contact medical direction before taking any action.

• Apply the defibrillator pads and shock as indicated.

In which of the following ways does cardiac arrest in children differ from cardiac arrest in adults?

• Cardiac arrest in children is more likely to be due to respiratory failure.

• Ventricular fibrillation is not common in adults.

• Ventricular fibrillation is common in children.

• Cardiac arrest in adults is more likely to be due to respiratory failure.

You are preparing a patient in cardiac arrest for an AED when you palpate a small lump below the patient's right clavicle. How should this modify your placement of the AED?

• Place the AED as you would for any patient.

• Place the AED pads over the patient's abdomen.

• Do not place the AED but transport the patient immediately.

• While placing the pads in the general area you need them, keep them several inches away from the lump.

Mechanical CPR devices are used by EMS agencies in order to provide:

• high-quality compressions.

• a 100% success rate.

• a faster response time to the scene

• better quality of care with less training.
