The best answer is: true

Initiating futile care is medically improper. Once futility is diagnosed, it is proper to prescribe "do not attempt to resuscitate" (DNR) in the patient record.

The best answer is: 1 and 3 only

The essential contraindications to aspirin are true aspirin allergy as well as recent or active GI bleeding.

The best answer is: all of the above

According to the most recent Guidelines, the following are relative exclusion criteria:

• Symptoms that seem minor and are clearing rapidly
• Onset of symptoms accompanied by seizure with residual impairment
• Significant trauma or surgery in the previous 14 days
• GI or GU hemorrhage with the last 21 days
• Acute MI within 3 months

The above need to be considered by carefully weighing the risk vs. the benefit when deciding to employ fibrinolytic therapy.

The best answer is: All of the above

Based on the most recent Guidelines for CPR & ECC, chest compressions, rather than ventilation is encouraged when finding a collapsed victim. As soon as other trained rescuers arrive, ventilation should begin. Once an advanced airway (ET tube, etc.) is in place, ventilation should be given at a rate of 8 – 10 per minute. In the event a collapsed victim is no longer breathing and has a pulse, rescue breathing should be immediately initiated.

The best answer is: intra-chamber electrograms done in the EP lab (EP study)

Cardiologist electrophysiologists routinely perform intra-chamber electrograms in the Electrophysiology Lab and determine with certainty the electrophysiologic mechanisms of complex arrhythmias. Surface ECG's are not useful for this purpose.
