BLS Review & Airway Management

Which PETCO2 indicates quality CPR?

• 18 mmHg

• 10 mmHg

• 5 mmHg

• 0 mmHg

During CPR you observe a PETCO2 of 9 mmHg, what should you do?

• Continue what you're doing, that indicates quality CPR

• Change chest compressors

• Reduce the ventilation rate

• Reintubate the patient

PETCO2 suddenly increases to 40 mmHg during CPR, what should you do next?

• Improve CPR quality

• Change chest compressors

• Resuscitation efforts are futile, CPR should be terminated

• ROSC has been achieved, perform post-cardiac arrest care

Squeeze the Ambu bag once every _______ to achieve proper ventilation.

• 8 seconds

• 1 second

• 6 seconds

• 10 seconds

During respiratory arrest, correct ventilation technique includes all of the following EXCEPT:

• Observe visible chest rise

• Deliver the breath over 1 second

• Squeeze the Ambu bad 1/2 squeeze

• Deliver 1 breath every 10 seconds

Excessive ventilation can cause all of the following EXCEPT:

• Increased venous return

• Cerebral ischemia

• Gastric inflation

• Vomiting

The most reliable way to confirm AND monitor correct ETT placement includes:

• Colormetric capnography

• Continuous waveform capnography

• Visualization of the vocal cords while intubating

• Auscultating the lungs

The appropriate measurement of an OPA includes

• Corner of mouth to the angle of the mandible

• Tip of the nose to the earlobe

• Corner of the mouth to the tip of the nose

• Tip of the mandible to the earlobe

A spontaneously breath patient's SpO2 is 87%, what initial action should you take?

• Call a rapid response

• Give the patient supplemental oxygen

• Perform CPR starting with compressions

• Continue to monitor the patient

Agonal gasps indicate

• Normal periodic breathing

• Respiratory distress

• ROSC

• Respiratory or cardiac arrest
