This domain is part of the Basic Life Support (BLS) practice test. Each question is tagged by exam objective and difficulty so you can drill exactly the areas you need.
Sample Questions
AHA Part 1 lists the skills tests a student must pass to earn a BLS course completion card. Which two tests are required?
- A. The Adult CPR and AED Skills Test and the Infant CPR Skills Test
- B. Only the Adult CPR Skills Test
- C. The Bag-Mask Skills Test and the Stroke Recognition Skills Test
- D. A 5-day clinical rotation in a hospital
AHA Part 1 names the Adult CPR and AED Skills Test and the Infant CPR Skills Test as the two skills tests required to receive the course completion card.
AHA Part 1 defines an 'infant' for BLS purposes. Which range matches the manual's definition?
- A. From age 1 through puberty
- B. Younger than 1 year, excluding newly born infants in the delivery room
- C. From birth through age 5
- D. Younger than 6 months only
AHA Part 1 defines an infant as someone younger than 1 year, excluding newly born infants in the delivery room.
An instructor reviews how a student earns their BLS course completion card. According to AHA Part 1, what minimum passing score is required on the written exam in the instructor-led course?
- A. 60 percent
- B. 75 percent
- C. 84 percent
- D. 99 percent
AHA Part 1 specifies a minimum passing score of 84 percent on the written exam of the instructor-led BLS course.
AHA Part 1's high-quality CPR callout describes how rescuers should give each rescue breath. Which combination matches?
- A. Deliver each breath over 1 second, using only enough volume to make the chest rise; avoid excessive ventilation
- B. Deliver each breath over 5 seconds, with maximum volume
- C. Skip breaths entirely during BLS
- D. Deliver each breath as forcefully as possible to overcome resistance
AHA Part 1 specifies delivering each breath over 1 second, using only enough volume to make the person's chest rise, and avoiding excessive ventilation.
A new BLS provider asks who decides which PPE they must wear in the workplace. According to AHA Part 1, where should they look for the role-specific PPE protocols?
- A. Only the BLS Provider Manual lists every required item
- B. A nationally posted list with no local variation
- C. Their employer, local health authority, or regulatory body
- D. The patient or family at the scene
AHA Part 1 directs rescuers to ask their employer, local health authority, or regulatory body about PPE protocols for their role.
Your CPR feedback monitor shows an average compression depth of 2.6 inches (6.6 cm) on an adult. AHA Part 1 explicitly caps adult depth. What is the upper limit?
- A. No more than 1.5 inches (4 cm)
- B. No more than 2 inches (5 cm)
- C. No more than 2.4 inches (6 cm)
- D. No more than 4 inches (10 cm)
AHA Part 1 specifies adult compressions should be at least 2 inches (5 cm) but no more than 2.4 inches (6 cm).
You are caring for a 13-year-old who has visible chest hair and is in cardiac arrest. According to AHA Part 1, which BLS approach is appropriate?
- A. Use pediatric BLS based on chronologic age
- B. Use neonatal resuscitation guidelines
- C. Wait for parental consent before any care
- D. Treat as an adult because there are signs of puberty
AHA Part 1 lists chest or underarm hair on males and any breast development on females as signs of puberty, after which BLS treats the patient as an adult.
AHA Part 1's high-quality CPR callout sets a target for how quickly compressions must begin once cardiac arrest is recognized. What is that target?
- A. Within 30 seconds after recognizing cardiac arrest
- B. Within 10 seconds after recognizing cardiac arrest
- C. Within 1 minute after recognizing cardiac arrest
- D. Within 5 minutes after recognizing cardiac arrest
AHA Part 1 specifies starting compressions within 10 seconds after recognizing cardiac arrest.
Key Terms in This Domain
- Compression Depth: Adults: ≥2 inches (5 cm). Child: ~2 inches (5 cm) or 1/3 chest depth. Infant: ~1.5 inches (4 cm) or 1/3 chest depth.
- Rescue Breathing: Without compressions: 1 breath every 6 seconds (adults), 1 every 2-3 seconds (children/infants). Each breath ~1 second.
- Compression-to-Ventilation Ratio: 30:2 for single-rescuer adult/child/infant. 15:2 for 2-rescuer infant/child. Continuous compressions with advanced airway.
- Pulse Check: Adult/child: carotid pulse (or femoral). Infant: brachial pulse. Check no more than 10 seconds.
- Chain of Survival: AHA framework: recognition and activation, early CPR, rapid defibrillation, advanced resuscitation, post-cardiac-arrest care, and recovery.
- Pediatric AED Pads: Use pediatric pads/dose attenuator on infants and children under 8 if available; adult pads acceptable if not.
- Switching Compressors: Rotate every 2 minutes (or every 5 cycles of 30:2) to maintain compression quality. Minimize pause to <5 seconds.
- High-Quality CPR: Push hard (≥2 in / 5 cm adults), push fast (100-120/min), allow full recoil, minimize interruptions, and avoid excessive ventilation.
- Compression Rate: 100-120 compressions per minute for all ages.
- Chest Recoil: Allow the chest to return fully between compressions; leaning prevents venous return and reduces CPR effectiveness.
