First Aid, CPR & EMS study guides
CPR, AED, and first-aid steps — as decision trees and rate/ratio tables, not bare answer keys.
15 explained questions, each with the answer, a worked explanation, and something interactive to help it stick.
- A Person Who Responds but Is Not Fully Awake Should Be Placed in What Position?Place them in the recovery position—rolled onto their side. This keeps the airway open and lets fluids or vomit drain out of the mouth, preventing choking in someone who is drowsy, semi-conscious, or not fully alert but still breathing.Read the guide
- What is recommended to minimize interruptions in compressions when using an AED?Keep performing chest compressions while the AED is retrieved and the pads are applied, and pause only when the AED instructs you to for rhythm analysis or a shock. Keep every pause under 10 seconds to maximize blood flow.Read the guide
- When using a pocket mask, where should the rescuer be positioned?At the top of the victim's head (the cephalic position). This lets a lone rescuer tilt the head to open the airway, form a tight two-hand C-E seal on the mask, and watch the chest rise during each breath.Read the guide
- If the patient's chest is not inflating during the breathing task, you should check the patient's what?Check the patient's AIRWAY. If the chest does not rise during rescue breaths, reopen the airway with a head-tilt/chin-lift, look for and clear any obstruction, and re-seal the mask before attempting the breath again.Read the guide
- How is CPR performed differently when an advanced airway is in place?With an advanced airway in place, rescuers give continuous chest compressions at 100-120 per minute without pausing for breaths, while one rescuer delivers a ventilation once every 6 seconds (about 10 breaths per minute). The 30:2 compression-to-ventilation cycle is abandoned.Read the guide
- When Should the Rescuer Operating the AED Clear the Victim?Twice: first when the AED is analyzing the heart rhythm, and again immediately before delivering a shock. No one may touch the victim during analysis or when the AED prompts "stand clear," because contact can distort the reading or cause the rescuer to be shocked.Read the guide
- What Are You Legally Required to Do Before You Touch a Person When Responding to an Emergency?You are legally required to obtain the person's consent before touching them. For a conscious, competent adult you must get expressed (explicit) permission; for an unconscious or unresponsive person, consent is legally implied, so you may proceed with care.Read the guide
- Which of the following are components of high-quality CPR for children? (Select 3 answers)The three components of high-quality pediatric CPR are: (1) an adequate compression rate of 100 to 120 per minute at a depth of at least one-third the chest's front-to-back diameter, (2) allowing full chest recoil between compressions, and (3) minimizing interruptions in chest compressions.Read the guide
- What are the steps you should follow for any injury or environmental emergency?For any injury or environmental emergency, follow the three C's: Check the scene and the victim, Call 911 (or have someone call), and Care for the person until help arrives. Always make sure the scene is safe before you approach.Read the guide
- When a patient is unconscious and non-responsive, should CPR be performed?True, in the sense the quiz intends: an unresponsive person who is not breathing normally (or is only gasping) and has no pulse needs CPR. But unresponsiveness alone is not enough — you must first confirm no normal breathing before starting chest compressions.Read the guide
- How Do You Open the Airway for Breaths When a Single Rescuer Is Present?Use the head-tilt/chin-lift maneuver: place one hand on the forehead and tilt the head back, then use the fingers of your other hand under the bony part of the chin to lift it, moving the tongue off the airway. If you suspect a spinal injury, use the jaw-thrust instead.Read the guide
- What is the preferred method for a pulse check in an infant?Palpate the brachial pulse: place 2–3 fingers on the inside of the upper arm between the shoulder and elbow, and feel for 5 to no more than 10 seconds. It is preferred because an infant's short, thick neck makes the carotid pulse hard to locate.Read the guide
- What Is a Sign of Severe Airway Obstruction?Signs of severe airway obstruction include a weak or silent cough, inability to speak, cry, or breathe, high-pitched or absent breathing sounds (stridor), bluish skin (cyanosis), and the universal choking sign — clutching the throat with both hands.Read the guide
- Which of these best describes the purpose of "Hands-Only" CPR?Hands-Only CPR gives untrained bystanders a simple, effective way to keep oxygenated blood circulating to the brain and vital organs, using continuous chest compressions with no rescue breaths, until EMS arrives. This maintained blood flow improves survival for a collapsed teen or adult.Read the guide
- What is your risk of getting infected with a disease while giving first aid care?The risk is LOW. Catching a disease while giving first aid is uncommon, especially when you use protective barriers such as gloves and a CPR breathing mask and follow good hygiene. Following universal precautions and washing your hands afterward keeps the risk very low.Read the guide
