What is the maximum dosage frequency and time frame for nitroglycerin administration for one chest pain incident?
Answer(s): A
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?
Answer(s): C
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?
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 _______________.
Answer(s): B
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.
Answer(s): D
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.
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?
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?
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.

q252: dns poisoning is the correct answer, not locator redirection. beaconing is detected from a host. this indicates that the system has been infected with malware, which could be the source of local dns poisoning. location redirection works by either embedding the redirection in the original websites code or having a user click on a url that has an embedded redirect. since users at a different office are not getting redirected, it isnt an embedded redirection on the original website and since the user is manually typing in the url and not clicking a link, it isnt a modified link.
