What is the maximum dosage frequency and time frame for nitroglycerin administration for one chest pain incident?

  1. 3 doses, allowing 5 minutes in between doses
  2. 2 doses, allowing 5 minutes in between doses
  3. 6 doses within 30 minutes
  4. 4 doses, allowing 10 minutes in between doses

Answer(s): A

Explanation:

Note that the administration of nitroglycerin should not be done with a patient whose systolic blood pressure is below 100 mg/Hg or who have taken medication for erectile dysfunction within the past 24 to 36 hours. If given, the maximum dosage should not be exceeded without express orders from a physician. Nitroglycerin given in higher doses may negatively impact cardiovascular condition.
Note: States set their own limits on dosage for this, so check local requirements.



What is the correct placement of the color-coded ECG cables?

  1. white-pt right shoulder, black-pt left shoulder, red-pt right hip, green-pt left hip
  2. white-pt right hip, black-pt left shoulder, red-pt left hip, green-pt right shoulder
  3. white-pt right shoulder, black-pt left shoulder, red-pt left hip, green-pt right hip
  4. white-pt right shoulder, black-pt right hip, red-pt left hip, green-pt left shoulder

Answer(s): C

Explanation:

There must be a consistent placement regime to create and ensure quality ECG tracing results that accurately reflect heart activity.



What specific measures are taken for a patient experiencing symptoms of an acute myocardial infarction (AMI) who also has a history of heart bypass or an internal defibrillator?

  1. Never start CPR before clearing with the ER physician.
  2. Check to see if the patient has the classic bypass scar.
  3. Implement the same measures as for any patient with AMI symptoms.
  4. Avoid performing CPR on patient with an internal defibrillator.

Answer(s): C

Explanation:

All patients, regardless of heart history, will receive the same assessment and treatment related to cardiac emergencies. There are no special indications for a patient with history of cardiac devices or surgery. However,
for patients with internal defibrillators, make sure to note that defibrillator pads are not touching or covering the internal defibrillator.



Continuous pumping performed by a left ventricular assist device (LVAD) impacts the ability to ______________ the patient’s _______________.

  1. treat, cardiac arrest
  2. palpate, pulses
  3. assess, blood pressure
  4. treat, respiratory symptoms

Answer(s): B

Explanation:

The left ventricular assist devices (LVAD) mechanism can be pulsatile or continuous.
When the pumping mechanism is continuous, there are no palpable pulses. It is possible to assess the LVAD patient’s blood pressure – you’ll just need to use a manual, not automated, cuff and have the Doppler US probe over the brachial artery.



You come on the scene of a 2-year-old patient with her grandparents. The child has no pulse, is unresponsive, and does not have a history of heart problems. No CPR has been initiated. Select the best option for the next steps.

  1. Attach AED and use chest thrust in case of aspiration.
  2. Attach AED and perform four back slaps.
  3. Shake and shout.
  4. Begin the CPR process and attach an AE

Answer(s): D

Explanation:

Cardiac arrest is uncommon in children with no history. If there are no pulses, a respiratory incident is most likely the cause. Starting CPR for a child will initiate the assessment of airway obstruction and the AED will help guide cardiac concerns.



Identify the sequential links of the chain of survival for cardiac emergencies.

  1. Activate EMS and identify early warning signs, AED use, basic and advanced EMS, ALS post care.
  2. Identify early warning signs and activate EMS, CPR, basic and advanced EMS, ALS post care.
  3. Activate EMS and basic and advanced EMS, identify early warning signs, CPR, and AED use.
  4. Identify early warning signs and activate EMS, CPR, AED use, basic and advanced EMS, ALS post care.

Answer(s): D

Explanation:

There are five vital steps in this chain of care. The key to success is the sequential administration of the links, in order, without missing a link. Missing one link decreases the chance of survival.
Note that CPR should be immediately resumed after the first AED shock. Also, the AED will analyze the patient’s heart function and prompt the user concerning shocks and use of continued CPR.



If your AED says, “no shock advised” because patient rhythm is asystole, what is your immediate next step?

  1. No intervention is needed.
  2. Begin CPR, starting with heart auscultation.
  3. Begin CPR, starting with compressions.
  4. Begin CPR, starting with two quick breaths.

Answer(s): C

Explanation:

To provide immediate support, manual CPR should be started, even if the patient is asystole and the AED says not to shock.



You encounter a 4-month-old baby in cardiac arrest of unknown cause.
What type of defibrillator is recommended and ideal to use?

  1. AED with pediatric dose attenuator
  2. manual defibrillator
  3. AED without pediatric dose attenuator
  4. any AED

Answer(s): B

Explanation:

Most pediatric cardiac emergencies are related to respiratory events. For the person who is allowed to defib an infant (this may not be you), a manual defibrillator is the most accurate device to use.
If a manual device is not available, the EMT manual (most used in EMT classes) recommends an AED with a pediatric dose attenuator. If neither is available, a regular AED may be used, following the device manual’s instructions for pediatric use. See: American Academy of Orthopaedic Surgeons (AAOS). Emergency Care and Transportation of the Sick and Injured. Jones & Bartlett Learning.
Of course, you’ll need to follow all local protocols for defibrillation as you do with other procedures. Some local services do not permit manual or other defibrillation by certain levels of EMTs.
