Free NC-BLET First Responder Medical Care Questions and Answers — Questions and Answers
Question 1: Upon arriving at the scene of a medical emergency, what is the very first priority for a first responder?
- Begin chest compressions on the victim.
- Check the victim for a pulse.
- Ensure the scene is safe for responders and the victim. (Correct answer)
- Immediately apply a tourniquet.
Correct answer: Ensure the scene is safe for responders and the victim.
The first and most critical step in any emergency response is to assess scene safety. This involves identifying and mitigating any potential hazards (e.g., traffic, fire, downed power lines, violent individuals) before approaching the patient to provide care.
Question 2: What is the first and most effective method for controlling severe external bleeding?
- Applying a tourniquet above the wound.
- Applying direct, firm pressure to the wound. (Correct answer)
- Elevating the injured limb above the heart.
- Applying pressure to a nearby pressure point.
Correct answer: Applying direct, firm pressure to the wound.
The primary and initial step for controlling severe bleeding is to apply firm, direct pressure over the wound using a sterile dressing or clean cloth. This helps the blood to clot. If direct pressure is not effective for life-threatening extremity hemorrhage, then a tourniquet should be considered.
Question 3: Which of the following are common signs and symptoms of a person going into shock?
- Flushed, warm skin and a slow, bounding pulse.
- Pale, cool, clammy skin and a rapid, weak pulse. (Correct answer)
- High blood pressure and deep, regular breathing.
- A sudden high fever and constricted pupils.
Correct answer: Pale, cool, clammy skin and a rapid, weak pulse.
Shock (hypoperfusion) is a critical condition where the circulatory system fails to provide enough oxygenated blood to the body. Key signs include pale or bluish skin that is cool and moist (clammy), a rapid and weak pulse, rapid breathing, nausea, and altered mental status.
Question 4: What is the correct rate and depth for chest compressions when performing CPR on an adult?
- 80-100 compressions per minute at a depth of 1 inch.
- 100-120 compressions per minute at a depth of at least 2 inches. (Correct answer)
- 120-140 compressions per minute at a depth of 3 inches.
- 60-80 compressions per minute at a depth of 1.5 inches.
Correct answer: 100-120 compressions per minute at a depth of at least 2 inches.
According to current guidelines, high-quality CPR on an adult requires pushing hard and fast. The correct rate is between 100 and 120 compressions per minute, and the depth should be at least 2 inches (5 cm) but no more than 2.4 inches (6 cm).
Question 5: You encounter an unconscious adult victim with life-threatening injuries. Under which legal principle can you provide medical care?
- Expressed consent
- Informed consent
- Implied consent (Correct answer)
- The Good Samaritan Act
Correct answer: Implied consent
Implied consent allows first responders to provide treatment to a patient who is unconscious, confused, or seriously ill and therefore unable to grant consent. It is based on the assumption that the person would agree to be treated if they were conscious and able to make a rational decision.
Question 6: In a mass casualty incident, a victim who has a minor laceration and is walking around would be triaged into which category?
- Immediate (Red)
- Delayed (Yellow)
- Minor (Green) (Correct answer)
- Deceased/Expectant (Black)
Correct answer: Minor (Green)
Triage is the process of sorting patients based on the severity of their injuries to determine the priority of treatment. A victim with minor injuries who is conscious and able to walk is categorized as Minor (Green tag) and is typically the last to receive definitive medical care.
Question 7: What is the most common cause of airway obstruction in an unconscious person?
- A foreign object
- Blood or vomit
- The tongue (Correct answer)
- Swelling from an allergic reaction
Correct answer: The tongue
When a person becomes unconscious, the muscles in their jaw relax, which can cause the tongue to fall back and block the upper airway. This is the most frequent cause of airway obstruction, which is why opening the airway using a technique like the head-tilt, chin-lift is a critical first step in patient assessment.
