A peace officer acting as a First Responder may lawfully administeremergency medical services to a victim when the:
Correct Answer
D. All of the above.
Explanation
A peace officer acting as a First Responder may lawfully administer emergency medical services to a victim when the victim has given clear consent. Additionally, the officer can provide aid if it is within the scope of their training. Furthermore, if the victim is unable to give consent due to a developmental disability, the officer can still administer emergency medical services. Therefore, all of the above options are correct.
2.
After a peace officer encounters an unresponsive adult victim and determinesthe scene is safe, the first action the officer should take is to:
Correct Answer
C. Ensure that the victim has an open airway.
Explanation
After ensuring that the scene is safe, the first action the officer should take is to ensure that the victim has an open airway. This is because an open airway is crucial for the victim to breathe properly. Checking for a pulse and attempting to determine if the victim is breathing would be secondary steps after ensuring the airway is open. Immediately beginning CPR would only be necessary if the victim is not breathing and does not have a pulse, which can be determined after ensuring the airway is open.
3.
Which of the following is a means of transmission for the hepatitis virus fromthe reservoir to a susceptible host?
Correct Answer
A. Blood
Explanation
Blood is a means of transmission for the hepatitis virus from the reservoir to a susceptible host. Hepatitis viruses can be present in the blood of an infected individual and can be transmitted through contact with infected blood. This can occur through activities such as sharing needles, receiving contaminated blood transfusions, or having unprotected sexual contact with an infected person. It is important to practice safe behaviors and take precautions to prevent the transmission of hepatitis viruses through blood.
4.
Peace officers should treat all body fluids as if they are contaminated bypathogens such as hepatitis or HIV.
Correct Answer
A. True
Explanation
Peace officers should treat all body fluids as if they are contaminated by pathogens such as hepatitis or HIV because these diseases can be transmitted through contact with infected bodily fluids. Treating all body fluids as potentially contaminated helps to minimize the risk of transmission and ensures the safety of both the peace officers and the individuals they come into contact with. It is important for peace officers to follow proper safety protocols, such as wearing personal protective equipment, when dealing with body fluids to prevent the spread of infectious diseases.
5.
An officer should assess a victim's breathing by:
Correct Answer
D. All of the above.
Explanation
An officer should assess a victim's breathing by looking for the rise and fall of the victim's chest, listening for breathing sounds, and feeling for breath from the victim's nose or mouth. This comprehensive approach allows the officer to gather multiple indicators of the victim's breathing status and ensure a thorough assessment.
6.
A peace officer can determine the victim's level of consciousness by:
Correct Answer
A. Checking the victim's response to painful stimuli.
Explanation
A peace officer can determine the victim's level of consciousness by checking the victim's response to painful stimuli. This is because the response to painful stimuli, such as squeezing a finger or applying pressure, can indicate whether the victim is conscious or not. If the victim responds to the stimuli by showing signs of pain or discomfort, it suggests that they are conscious. On the other hand, if there is no response or the response is minimal, it may indicate a loss of consciousness. This method helps the peace officer assess the victim's condition and provide appropriate medical assistance if needed.
7.
When assessing an adult's circulation, which artery is preferred for feeling avictim's pulse?
Correct Answer
A. Carotid
Explanation
When assessing an adult's circulation, the carotid artery is preferred for feeling a victim's pulse. The carotid artery is located in the neck, close to the surface, making it easily accessible and providing a strong and reliable pulse. The femoral artery is located in the groin area and may be more difficult to locate and assess. The brachial artery is located in the upper arm and is commonly used for assessing an infant's pulse. Therefore, the carotid artery is the preferred choice for assessing an adult's circulation.
8.
In a situation where there are multiple victims, the order of consideration fordetermining treatment priorities is:
Correct Answer
B. Breathing, circulation, mental status.
Explanation
In a situation where there are multiple victims, the order of consideration for determining treatment priorities is breathing, circulation, mental status. This means that the first priority is to assess and address any issues related to the victims' ability to breathe. This is crucial because without a clear airway and proper breathing, the victims' lives are immediately at risk. Once breathing has been addressed, the next priority is to assess and address any issues related to circulation, such as severe bleeding or shock. Finally, mental status is considered, as it indicates the victims' level of consciousness and neurological function.
9.
Generally, a rapid head-to-toe examination of a victim is conducted with thevictim in which one of the following positions?
Correct Answer
D. The position in which the victim was found
Explanation
The correct answer is "The position in which the victim was found." When conducting a rapid head-to-toe examination of a victim, it is important to assess their condition in the position they were found in. This allows the examiner to observe any visible injuries or signs of distress that may have occurred as a result of their position. By assessing the victim in the position they were found, it provides important information for determining the appropriate course of action and treatment.
10.
If a newborn fails to begin breathing on its own after birth, the officerassisting with the birth should:
Correct Answer
A. Rub the infant's back or tap the infant's feet to stimulate breathing.
Explanation
If a newborn fails to begin breathing on its own after birth, the officer assisting with the birth should rub the infant's back or tap the infant's feet to stimulate breathing. This is because gentle stimulation can help stimulate the baby's respiratory system and encourage them to start breathing. It is a non-invasive and safe method to initiate breathing in newborns. Immediate rescue breathing or CPR may not be necessary unless the baby does not respond to the stimulation. Slapping the infant or picking them up by their feet is not recommended as it can cause harm to the baby.
11.
An unconscious victim should be moved from the site where found only if:
Correct Answer
B. The original location places the victim or officer in imminent danger.
Explanation
It is important to only move an unconscious victim if their original location places them or the officer in imminent danger. This means that if the victim is in a position where they could be harmed further or if the officer's safety is at risk, it is necessary to move the victim to a safer location. However, if the victim's original position does not pose any immediate danger, it is recommended to leave them in that position until medical professionals arrive to avoid causing further harm.
12.
If it becomes necessary to move an unconscious victim to a different location,the peace officer should:
Correct Answer
B. Keep the victim's head and shoulders as close as possible to the ground.
Explanation
The correct answer is to keep the victim's head and shoulders as close as possible to the ground. This is important because it helps to minimize any potential movement or strain on the victim's neck and spine, which could potentially aggravate any existing injuries. By keeping the head and shoulders close to the ground, it helps to maintain the victim's alignment and reduces the risk of further harm.
13.
When a spinal cord injury is suspected, which of the following maneuversshould be used to open the victim's airway?
Correct Answer
D. Jaw-thrust maneuver
Explanation
The jaw-thrust maneuver should be used to open the victim's airway when a spinal cord injury is suspected. This maneuver involves placing the fingers behind the angles of the lower jaw and lifting it forward, without tilting the head or neck. It is specifically recommended in cases where there may be a risk of spinal cord injury, as it minimizes movement of the cervical spine and reduces the potential for further damage. By using the jaw-thrust maneuver, the airway can be opened without compromising the stability of the neck.
14.
If a victim indicates that he is choking but can still speak or cough, a peaceofficer may presume that the victim is experiencing a partial airwayobstruction.
Correct Answer
A. True
Explanation
If a victim is able to speak or cough despite indicating that they are choking, it suggests that their airway is only partially obstructed. This means that there is still some airflow getting through, allowing them to make sounds. Therefore, a peace officer can reasonably assume that the victim is indeed experiencing a partial airway obstruction.
15.
Abdominal thrusts may be used to clear a complete airway obstruction onwhich of the following victims?
Correct Answer
D. Conscious ten-year-old child
Explanation
Abdominal thrusts may be used to clear a complete airway obstruction on a conscious ten-year-old child because this technique can help dislodge the object blocking the airway and restore normal breathing. It is not recommended to use abdominal thrusts on an unconscious infant as it may cause harm. Similarly, it is not suitable for a conscious pregnant woman or a conscious, morbidly obese man as these individuals may require different techniques or medical assistance to clear an airway obstruction. Therefore, the correct answer is a) and d) only.
16.
A seven-year-old girl has been bitten on the arm by the neighbor's dog. Thearea of the bite is red and a bit swollen, but the bite itself has left only a smallset of puncture marks. There was only minimal bleeding, which had stoppedwhen the peace officer arrived on the scene. The girl is being cared for by hermother. The officer should advise the mother to:
Correct Answer
A. Wash the site with soap and water.
Explanation
The correct answer is to wash the site with soap and water. This is because washing the bite with soap and water helps to clean the wound and reduce the risk of infection. Running cool water over the wound and applying hydrogen peroxide may also be beneficial, but the most important step is to clean the area with soap and water. Covering the site with a clean occlusive bandage can help protect the wound from further contamination. Therefore, advising the mother to wash the site with soap and water is the most appropriate course of action.
17.
Officers should attempt to cool a heat stroke victim as quickly as possible.
Correct Answer
A. True
Explanation
Heat stroke is a life-threatening condition that occurs when the body's temperature regulation system fails, causing the body temperature to rise to dangerous levels. Immediate cooling is crucial to prevent further damage and potentially save the victim's life. By cooling the heat stroke victim as quickly as possible, officers can help lower the body temperature and reduce the risk of organ damage or failure. Delaying cooling measures can lead to severe complications and even death, making it essential to act swiftly in these situations.
18.
A victim has suffered a closed chest wound in a vehicle collision. The victimcomplains of painful breathing and one segment of the chest wall does notmove with the rest of the chest. Based on this information, which of thefollowing injuries would you suspect the victim has suffered?
Correct Answer
B. Flail chest
Explanation
Based on the information provided, the victim's complaint of painful breathing and the observation that one segment of the chest wall does not move with the rest of the chest, it is likely that the victim has suffered a flail chest. Flail chest occurs when multiple ribs are fractured in two or more places, causing a segment of the chest wall to become detached from the rest of the chest. This can result in paradoxical movement of the chest during breathing, leading to painful breathing.
19.
When performing rescue breathing on an unconscious l4-year-old victim, apeace officer should use only enough air to create a gentle rise in the victim'schest.
Correct Answer
A. True
Explanation
When performing rescue breathing on an unconscious 14-year-old victim, using only enough air to create a gentle rise in the victim's chest is the correct approach. This is because using too much air can cause harm or injury to the victim, especially if they are a child. By using just enough air to create a gentle rise, the peace officer ensures that the victim receives the necessary oxygen without causing any further harm.
20.
When performing CPR on an unconscious adult, the officer should check thevictim's pulse at which artery?
Correct Answer
D. Carotid
Explanation
When performing CPR on an unconscious adult, the officer should check the victim's pulse at the carotid artery. The carotid artery is located in the neck and is easily accessible during CPR. Checking the pulse at this artery allows the officer to assess the victim's circulation and determine if CPR is necessary.
21.
When applying external compressions during CPR on a six-year-old child, the
chest should be compressed:
Correct Answer
C. 1 1/2 - 2 inches.
Explanation
For a six-year-old child, the appropriate depth for chest compressions during CPR should be about 1/3 to 1/2 the depth of the chest. Generally, this translates to approximately 1 1/2 - 2 inches deep.
22.
A peace officer stops to assist a motorist along the roadside in the high desert.The officer discovers that the driver, who was trying to change atire, has beenbitten by a snake. The motorist is not sure what type of snake bit him. Whatfirst aid measures should the officer take?
Correct Answer
E. B) and c) only
Explanation
The officer should keep the victim calm and place the affected area below the level of the victim's heart. These measures are important in managing a snakebite to minimize the spread of venom throughout the body. Making incisions near the fang marks and attempting to suck out the poison is not recommended as it can cause further harm and does not effectively remove the venom. Therefore, the correct answer is b) and c) only.
23.
When performing CPR on an adult, a peace officer should deliver chestcompressions at the rate of:
Correct Answer
D. 100 per minute.
Explanation
When performing CPR on an adult, it is recommended to deliver chest compressions at a rate of 100 per minute. This is because delivering chest compressions at this rate ensures that the heart is being effectively pumped and blood circulation is maintained. A higher rate of compressions helps to provide adequate oxygen supply to the brain and other vital organs, increasing the chances of survival for the patient.
24.
A young boy swimming at the beach with his older sibling is stung by anumber of jellyfish. The enzymes of the jellyfish's venom can be deactivatedby:
Correct Answer
B. Applying heat packs to the area.
Explanation
Applying heat packs to the area can deactivate the enzymes of the jellyfish's venom. Heat can denature proteins, which are the primary components of enzymes. By applying heat to the area, the enzymes in the venom can be disrupted and rendered inactive, reducing the effects of the sting. Cold packs, on the other hand, may provide temporary relief from pain and swelling but do not directly deactivate the enzymes. Elevating the area above the level of the heart and washing with soap and water are unrelated to deactivating the enzymes of the jellyfish's venom.
25.
When performing CPR on an infant, the officer should deliver cycles of :
Correct Answer
C. 30 compressions to 2 breaths.
Explanation
When performing CPR on an infant, the recommended ratio is 30 compressions to 2 breaths. This is the standard guideline for infant CPR, and it is essential to follow this ratio to provide effective life-saving measures for infants in need of resuscitation.
26.
Officers discover a man who spent the night on the street in near zerotemperatures. The victim's uncovered hands appear pale and waxy and theskin is stiff to the touch. What actions should officers take?
Correct Answer
B. Wrap the exposed digits separately and allow the extremities to rewarm slowly.
Explanation
The correct answer is to wrap the exposed digits separately and allow the extremities to rewarm slowly. This is the recommended action because the victim's hands appear pale and waxy, indicating possible frostbite. Rapid rewarming, such as soaking in hot water, can cause further damage to the tissues. By wrapping the exposed digits separately, the officers can protect them from further exposure and allow them to gradually warm up, minimizing the risk of tissue damage.
27.
Which of the following is an indication of possible shock?
Correct Answer
E. All of the above
Explanation
All of the above options are indications of possible shock. Shock is a life-threatening condition that occurs when the body does not receive enough blood flow. Dilated pupils can be a sign of shock as the body tries to increase blood flow to vital organs. Blue/grey lips and ears indicate poor oxygenation, which can occur in shock. Altered mental status is a common symptom of shock as the brain does not receive enough oxygen. A weak pulse is also characteristic of shock as the heart struggles to pump enough blood. Therefore, all of these signs together suggest the possibility of shock.
28.
Peace officers should give fluids to a conscious shock victim to preventdehydration.
Correct Answer
B. False
Explanation
Peace officers should not give fluids to a conscious shock victim to prevent dehydration. Giving fluids to a conscious shock victim can actually worsen their condition. Shock is a life-threatening condition where the body's organs and tissues do not receive enough oxygen and nutrients. It is important to seek medical help immediately in cases of shock, as professionals will be able to provide appropriate treatment and determine the best course of action for the individual.
29.
In the advanced stages of a respiratory emergency, the victim's skin mayappear:
Correct Answer
C. Blue-gray.
Explanation
In the advanced stages of a respiratory emergency, the victim's skin may appear blue-gray. This is due to a lack of oxygen in the bloodstream, resulting in a condition called cyanosis. Cyanosis causes the skin to take on a bluish or grayish tint, indicating that the body is not receiving enough oxygen. This is a serious sign of respiratory distress and requires immediate medical attention.
30.
Shock is a life threatening condition that can occur when:
Correct Answer
A. Inadequate blood is flowing to the tissues and organs.
Explanation
Shock is a life-threatening condition that occurs when there is inadequate blood flow to the tissues and organs. This can happen due to various reasons such as severe bleeding, heart failure, or severe infection. The other options, body temperature being too low or too high, and the brain lowering the respiration rate to preserve energy, are not directly related to shock. Therefore, the correct answer is inadequate blood flow to the tissues and organs.
31.
If bleeding from a laceration to an unconscious victim's lower right leg is notcontrolled adequately with direct pressure, the responding officer should nextconsider:
Correct Answer
C. Maintaining pressure over the wound and elevating the victim's right leg above the level of the victim's heart.
Explanation
If direct pressure is not controlling the bleeding from the laceration on the unconscious victim's lower right leg, the next step is to maintain pressure over the wound and elevate the victim's right leg above the level of the victim's heart. This helps to reduce blood flow to the area and promote clotting, which can help control the bleeding. Applying direct pressure to the brachial artery or femoral artery may not be effective in this situation, and applying a tourniquet should be a last resort.
32.
If a victim is suffering from a chemical burn to the skin caused by a drypowder, the peace officer acting as an EMS First Responder should:
Correct Answer
C. Brush away as much of the chemical as possible before flushing with
water.
Explanation
The correct answer is to brush away as much of the chemical as possible before flushing with water. This is because brushing away the dry powder will help remove any excess chemical from the skin, reducing further damage. Flushing with water should be done after brushing away the chemical to further dilute and remove any remaining residue. Removing exposed clothing should be done after flushing the area with water to prevent further exposure to the chemical.
33.
In the aftermath of a minor vehicle collision, the right cheek of one of theinvolved individuals is bruised and swollen. There are no other indications ofinjury. Which of the following first aid measures would be appropriate in thissituation?
Correct Answer
B. Putting an ice pack on the site to reduce swelling
Explanation
Putting an ice pack on the site to reduce swelling is the appropriate first aid measure in this situation. Applying cold to the injured area helps to constrict blood vessels, reduce blood flow, and minimize swelling. The ice pack should be wrapped in a cloth or towel before applying it to the bruised and swollen cheek to prevent direct contact with the skin and potential frostbite.
34.
Which of the following should officers recognize as an indicator of a possiblecardiac emergency?
Correct Answer
D. All of the above
Explanation
Officers should recognize all of the given indicators as possible signs of a cardiac emergency. An abnormally slow pulse can be a sign of a heart problem, radiating pain in the shoulder or jaw can be a symptom of a heart attack, and feelings of anxiety or impending doom can also be associated with a cardiac event. Therefore, recognizing all of these indicators is important in identifying and responding to a possible cardiac emergency.
35.
If some of a victim's organs are protruding from an open abdominal wound, apeace officer should apply gentle pressure in an attempt to move the organsback into the abdominal cavity and minimize infection.
Correct Answer
B. False
Explanation
Applying gentle pressure to move protruding organs back into the abdominal cavity is not recommended for a peace officer. This task should be left to medical professionals who are trained to handle such situations. Attempting to do so without proper knowledge and training can cause further damage and increase the risk of infection. Therefore, the correct answer is false.
36.
First aid for thermal bums includes stopping the burning process by coolingthe burned area with water.
Correct Answer
A. True
Explanation
The correct answer is true because when a person suffers a thermal burn, it is important to immediately stop the burning process by cooling the burned area with water. This helps to lower the temperature of the skin and prevent further damage. Water is effective in cooling the burn and providing relief to the injured person. It is recommended to cool the burn for at least 10-20 minutes with cool, running water.
37.
Wounds from electrical burns should be treated in the same manner as thosecaused by thermal burns.
Correct Answer
A. True
Explanation
Electrical burns and thermal burns should be treated in the same manner because both types of burns can cause similar damage to the skin and underlying tissues. The initial treatment for both types of burns involves cooling the affected area with cool (not cold) water to reduce pain and prevent further tissue damage. Afterward, the burn should be covered with a sterile dressing to protect it from infection. Additionally, pain management, wound cleaning, and monitoring for signs of infection are important steps in the treatment of both electrical and thermal burns. Therefore, the statement that wounds from electrical burns should be treated in the same manner as those caused by thermal burns is true.
