An adult patient in respiratory arrest with a pulse is ventilated via bag valve mask:

10-12 /min -When there is no advanced airway in place, ventilations should be given 10 to 12 times per minute. This translates to *one ventilation every 5 to 6 seconds.*

During cardiopulmonary resuscitation, deliver oxygen at: A 2 liters per minute via nasal cannula B Titrated to keep oxygen saturation ≥ 85% C Titrated to keep oxygen saturation ≥ 94% D 100%

100% CPR is performed during cardiac arrest and 100% oxygen should be administered during cardiac arrest.

The effectiveness of CPR can be estimated by: A Arterial diastolic blood pressure B Quantitative waveform capnography C Central venous oxygen saturation D All of the above

All of the above -All of these measures can inform providers about the quality of CPR. The quantitative waveform capnography goal is at *least 10 mm Hg during CPR*. Arterial diastolic blood pressure should be at *least 20 mm Hg during CPR*. Central venous oxygen saturation as measured by a Swan-Ganz catheter or equivalent should be at *least 30%*.

Which of the following signs is NOT part of the Cincinnati Prehospital Stroke Scale? A Facial droop B Arm drift C Speech abnormality D Confusion or disorientation

Confusion/ disorientation The Cincinnati Prehospital Stroke Scale can be remembered by the acronym FAST: Facial droop, Arm drift, Speech abnormality (slurring, usually), and Time. Time is not a symptom.

The most common reversible causes of PEA are called the "H's and T's" and include all of the following EXCEPT: A Hypovolemia B Hypoxia C Hypocalcemia D Tamponade

Hypocalcemia Hypocalcemia is not a common cause of PEA, nor is it part of the H's and T's mnemonic.

The goal for initiation of fibrinolytic therapy in appropriate stroke patients is: A Within 4 hours of arrival to the ED B Within 6 hours of arrival to the ED C Within 3 hours of arrival to the ED D Within 1 hour of arrival to the ED

Within 1 hr All diagnostic testing and checklists should be performed so that a fibrinolytic drug can be infused within 1 hour of arriving to the emergency department. The window from symptom onset is different (3 hours in most, 4.5 hours in some).
