1. Chest compressions for an adult are performed:
a. at a rate between 60–80 compressions per minute
b. at a rate of at least 80 compressions per minute
c. at a rate between 80–100 compressions per minute
d. at a rate between 100–120 compressions per minute
Correct Answer: d. at a rate between 100–120 compressions
per minute
Rationale:
Adult chest compressions should be performed at a rate of
100–120 compressions per minute. Maintaining this rate
supports adequate coronary and cerebral perfusion during
CPR while avoiding excessively rapid compressions that can
reduce compression depth and effectiveness.
,2. The ratio of compressions to breaths in adults is:
a. 15:1
b. 10:2
c. 20:2
d. 30:2
Correct Answer: d. 30:2
Rationale:
For adult CPR without an advanced airway, the recommended
compression-to-ventilation ratio is 30:2, regardless of whether
one or multiple rescuers are present. This provides adequate
chest compressions while allowing periodic ventilation.
3. An adult patient in respiratory arrest with a pulse is
ventilated via bag-valve mask:
a. 8–10 times per minute
b. 10–12 times per minute
c. 12–14 times per minute
d. 14–16 times per minute
Correct Answer: b. 10–12 times per minute
, Rationale:
An adult patient in respiratory arrest who has a pulse requires
rescue ventilation at approximately 10–12 breaths per
minute, equivalent to one ventilation every 5–6 seconds.
This provides adequate ventilation while minimizing the risk
of excessive ventilation.
4. Hypotension following cardiac arrest is NOT treated
with:
a. IV calcium infusion
b. IV dopamine infusion
c. IV epinephrine infusion
d. IV Ringer’s lactate or IV normal saline
Correct Answer: a. IV calcium infusion
Rationale:
Post-cardiac-arrest hypotension is generally managed with IV
fluids and/or vasopressors, such as epinephrine, to support
adequate perfusion. Routine IV calcium administration is not
a standard treatment for post-arrest hypotension unless a
specific indication, such as hypocalcemia, hyperkalemia, or
calcium-channel blocker toxicity, is present.
