Questions with Correct Answers Keys
100% Accurate and verified question with answers
Question 1
A patient is receiving ventilation support via bag-valve-mask (BVM)
resuscitator. Capnography is established and a blood gas is obtained to
evaluate the adequacy of the ventilations. Which arterial carbon dioxide
(PaCO₂) value signifies adequate ventilations?
A) 10–15 mmHg
B) 20–25 mmHg
C) 25–30 mmHg
D) 35–45 mmHg
✅ Answer: D) 35–45 mmHg
Explanation: Arterial carbon dioxide (PaCO₂) values in the range of 35–45
mmHg confirm adequacy of ventilation.
Question 2
A resuscitation team is debriefing following a recent event. A patient
experienced cardiac arrest, and advanced life support was initiated. The
patient required the placement of an advanced airway to maintain airway
patency. Which statement indicates that the team performed high-quality
CPR?
A) “We initiated chest compressions at a rate of 100 to 110 per minute to
a depth of 2.4 inches and then gave 1 ventilation every 10 seconds.”
B) “We provided chest compressions at a rate of 100 to 120 compressions
per minute while giving 1 ventilation every 6 seconds without pausing
compressions.”
, C) “We provided chest compressions at a rate of 80 to 120 per minute to a
depth of at least 2 inches and gave 1 ventilation every 6 seconds without
pausing compressions.”
D) “We kept the rate of chest compressions to around 100 per minute but
adjusted their depth to 1.5 inches while giving 1 ventilation every 3
seconds without pausing compressions.”
✅ Answer: B) “We provided chest compressions at a rate of 100 to 120
compressions per minute while giving 1 ventilation every 6 seconds
without pausing compressions.”
Explanation: When an advanced airway is placed, compressions are
continuous at 100–120 per minute, with ventilations given every 6
seconds and no pauses.
Question 3
Assessment of a patient reveals an ETCO₂ level of 55 mmHg and an
arterial oxygen saturation (SaO₂) level of 88%. The provider would
interpret these findings as indicative of which condition?
A) Respiratory failure
B) Respiratory arrest
C) Cardiac arrest
D) Respiratory distress
✅ Answer: A) Respiratory failure
Explanation: An SaO₂ level below 90% (PaO₂ < 50 mmHg) along with
ETCO₂ > 50 mmHg indicates respiratory failure.
Question 4
A responsive patient is choking. What method should the provider use first
to clear the obstructed airway?
A) Back blows
