Question 13. What is the recommended depth for chest compressions in an adult? A) At least 1 inch B) 1.5 inches C) At least 2 inches D) 3 inches Answer: C Explanation: Compressions should be at least 2 inches deep to generate sufficient blood flow during CPR.
Question 14. During CPR, the compression rate should be maintained at: A) 80-100 per minute B) 100-120 per minute C) 130-150 per minute D) 150-170 per minute Answer: B Explanation: The recommended rate is 100-120 compressions per minute, ensuring effective circulation without causing fatigue. Question 15. Why is full chest recoil important during CPR? A) To prevent chest injuries B) To allow the heart to refill with blood C) To minimize rescuer fatigue D) To improve airway patency Answer: B Explanation: Complete chest recoil allows the heart to refill with blood between compressions, maximizing blood flow during CPR.
Question 18. What is the correct compression-to-ventilation ratio for single-rescuer adult CPR? A) 15: B) 30: C) 10: D) 5: Answer: B Explanation: The standard ratio for adult single-rescuer CPR is 30 compressions to 2 breaths to maximize blood flow and oxygenation. Question 19. Which modification is appropriate when performing CPR on a child (1 year to puberty)? A) Use adult compression depth B) Use a compression depth of about 1.5 inches C) Use only rescue breaths D) Perform compressions with two hands Answer: B Explanation: Child CPR involves compressing about 1.5 inches, slightly less than adult depth, to match their smaller size.
Question 20. In the case of an infant, what is the recommended hand placement for chest compressions? A) Two fingers on the sternum B) Two hands on the chest C) One hand on the chest D) No specific placement Answer: A Explanation: For infants, two fingers are placed just below the nipple line on the sternum for compressions. Question 21. Which sign indicates a need for conscious choking relief in an adult? A) Unresponsiveness B) Mild coughing C) Inability to speak or breathe, cyanosis D) Excessive salivation Answer: C Explanation: Inability to speak or breathe, along with cyanosis, indicates severe airway obstruction requiring immediate choking relief.
Question 24. An AED analyzes the heart rhythm and advises a shock. What should the rescuer do immediately after the shock is delivered? A) Pause and reassess pulse B) Continue CPR starting with compressions C) Wait for EMS to arrive D) Remove the pads Answer: B Explanation: After shock delivery, immediately resume CPR with compressions to maintain blood flow until normal rhythm is restored or EMS takes over. Question 25. How should AED pads be placed on a victim's chest? A) One pad on the front, one on the back B) Both pads on the front of the chest C) On the upper right and lower left sides of the chest D) Random placement Answer: C
Explanation: Standard pad placement is one on the upper right chest and the other on the lower left side to allow proper rhythm analysis and shock delivery. Question 26. How should hair be managed if it interferes with AED pad placement on a hairy chest? A) Use alcohol wipes B) Shave or firmly press the pads to the skin C) Ignore hair and apply pads D) Use only pediatric pads Answer: B Explanation: Shaving or pressing the pads firmly ensures proper contact for accurate rhythm analysis and effective shock delivery. Question 27. What is a key consideration when using an AED on a wet victim? A) Use adult pads only B) Dry the victim's chest thoroughly before pad placement C) Use high energy shock settings D) Place pads over wet clothing
Explanation: Removing patches prevents interference with AED pad contact and avoids delivering electrical current to medication residues. Question 30. If an AED advises a shock but the victim is touching another person, what should the rescuer do? A) Shout for assistance B) Push the victim away and ensure no one is touching them C) Continue CPR without shocking D) Move the AED to a different location Answer: B Explanation: Ensuring no one is touching the victim prevents accidental shock to bystanders and ensures the shock is delivered effectively.
