CPR and Basic Life Support
1. When performing CPR on an adult, what is the correct compression-to-
ventilation ratio for a single rescuer?
• A) 15:2
• B) 30:2
• C) 5:1
• D) 30:1
Answer: B) 30:2
,Rationale: The compression-to-ventilation ratio for single-rescuer CPR in adults is
30 compressions to 2 ventilations. This ratio is designed to maximize coronary
perfusion pressure while providing adequate oxygenation. Option A (15:2) is the
ratio for two-rescuer CPR in children and infants. Option C (5:1) is an outdated
ratio. Option D (30:1) does not include ventilations, which would be inadequate for
cardiac arrest patients.
2. You are performing CPR on an adult patient. At what rate should chest
compressions be delivered?
• A) 60-80 compressions per minute
• B) 80-100 compressions per minute
• C) 100-120 compressions per minute
• D) 120-140 compressions per minute
Answer: C) 100-120 compressions per minute
Rationale: Current American Heart Association guidelines recommend chest
compressions be delivered at a rate of 100-120 per minute for all age groups. This
rate optimizes blood flow to vital organs during cardiac arrest. Option A (60-80) is
too slow and would not generate adequate perfusion. Option B (80-100) is below
the recommended rate. Option D (120-140) is too fast and may reduce compression
depth and recoil.
3. After insertion of an advanced airway device during adult cardiac arrest,
what is the appropriate ventilation rate?
• A) 8-10 breaths per minute
• B) 10-12 breaths per minute
• C) 12-15 breaths per minute
• D) 15-20 breaths per minute
Answer: A) 8-10 breaths per minute
,Rationale: Once an advanced airway (such as an ET tube or supraglottic airway) is
placed during cardiac arrest, ventilate at a rate of 8-10 breaths per minute (one
breath every 6-8 seconds) without interrupting chest compressions. Option B (10-
12) is the rate for patients with return of spontaneous circulation. Option C (12-15)
would cause hyperventilation. Option D (15-20) is excessive and would increase
intrathoracic pressure.
4. What is the maximum time you should take to check for breathing in an
unresponsive patient?
• A) 5 seconds
• B) 10 seconds
• C) 15 seconds
• D) 20 seconds
Answer: B) 10 seconds
Rationale: You should check for breathing for no more than 10 seconds when
assessing an unresponsive patient. This time frame allows you to detect adequate
or inadequate breathing without delaying initiation of CPR. Option A (5 seconds) is
too brief and may cause you to miss agonal respirations. Option C (15 seconds)
and Option D (20 seconds) delay care unnecessarily.
5. A 6-year-old child is in cardiac arrest. What is the correct compression-to-
ventilation ratio for two-rescuer CPR?
• A) 15:2
• B) 30:2
• C) 5:1
• D) 15:1
Answer: A) 15:2
, Rationale: For two-rescuer CPR in children (ages 1 to puberty) and infants, the
compression-to-ventilation ratio is 15:2. This ratio provides more ventilations
relative to compressions compared to adult CPR, reflecting the fact that cardiac
arrest in children is more often respiratory in origin. Option B (30:2) is the ratio for
single-rescuer child CPR and adult CPR. Option C (5:1) and Option D (15:1) are
not current recommendations.
6. When ventilating a patient with return of spontaneous circulation (ROSC),
at what rate should ventilations be delivered?
• A) 8-10 breaths per minute
• B) 10-12 breaths per minute
• C) 12-20 breaths per minute
• D) 20-24 breaths per minute
Answer: B) 10-12 breaths per minute
Rationale: After a patient achieves return of spontaneous circulation (ROSC),
ventilate at a rate of 10-12 breaths per minute. This rate maintains adequate
oxygenation while preventing hyperventilation, which can increase intrathoracic
pressure and reduce cardiac output. Option A (8-10) is the rate during cardiac arrest
with an advanced airway. Option C (12-20) and Option D (20-24) are too rapid and
may be harmful.
7. How should you determine unresponsiveness in a potential cardiac arrest
patient?
• A) Shout and tap the patient's shoulder
• B) Shake the patient vigorously
• C) Apply a painful stimulus immediately
• D) Check for pupil response
Answer: A) Shout and tap the patient's shoulder
