, while performing the BLS assessment, you initiate high-quality CPR and assist
ventilation with a bag-mask device
the AED does not recommend a shock
which action in the primary assessment should you perform first?
a) attach a quantitative waveform capnography device
b) perform fluid resuscitation
c) determine if the patient's airway is patent
d) assess the patient's oxygenation status - ...(answer)..C
the initial assessment reveals a conscious patient
the patient's airway is patent, and an advanced airway is not indicated
which action in the primary assessment should you perform next?
a) check for the presence of a pulse
b) remove clothing to perform a physical examination
c) administer oxygen as needed
d) check for neurologic function - ...(answer)..C
during CPR, chest compression fraction (CCF) should be at least % and idealls
greater than % - ...(answer)..60, 80

, among others, which of the following factors has been associated with improved
survival in patients with cardiac arrest?
a) compression-only CPR
b) presence of 2 or more rescuers
c) immediate high -quality CPR
d) manual defibrillation - ...(answer)..C
which action is part of the secondary assessment of a conscious patient?
a) formulate a differential diagnosis
b) attach a monitor/defibrillator
c) give IV/IO fluids if needed
d) determine the patient's level of consciousness - ...(answer)..a
