Free EMR Care Questions and Answers — Questions and Answers
Question 1: You saw a patient go into cardiac arrest and start CPR after dispatching another rescuer to obtain an AED and turn on the emergency response system. When a third rescuer shows up, he ought to:
- Get the AED and assist the second rescuer.
- assist with basic ventilation for face masks.
- aid in the ventilation of the bag mask. (Correct answer)
- remain vigilant and uphold scene security.
Correct answer: aid in the ventilation of the bag mask.
In a multi-rescuer CPR scenario, when a third rescuer arrives, their most effective role is to aid in the ventilation of the bag-mask device. This allows the primary rescuer to maintain continuous chest compressions, while the second rescuer focuses on the AED and emergency response system. This division of labor optimizes the efficiency and effectiveness of CPR.
Question 2: To check for a pulse, use:
- simply your thumb.
- two or three fingers. (Correct answer)
- Just one finger.
- one finger and your thumb.
Correct answer: two or three fingers.
When checking for a pulse, it is recommended to use two or three fingers (typically the index and middle fingers). Using multiple fingers provides a broader surface area, making it easier to locate the pulse reliably. Using only one finger might not be sufficient, and using the thumb is discouraged because it has its own strong pulse, which can be mistaken for the patient's.
Question 3: When providing a baby mouth-to-mouth breathing techniques:
- The child's lower lung volume means that no seal needs to be made.
- To make an airtight seal, cover the baby's mouth and nose with yours. (Correct answer)
- shut their mouth and only allow their nose to breathe.
- Making an airtight seal, clamp the patient's nose together and cover their mouth with yours.
Correct answer: To make an airtight seal, cover the baby's mouth and nose with yours.
When providing mouth-to-mouth breathing techniques to an infant, it is crucial to make an airtight seal by covering both the baby's mouth and nose with your mouth. Infants have smaller airways and noses, making it more effective to seal both simultaneously to ensure adequate ventilation. This technique helps deliver breaths efficiently to their smaller lung volume.
Question 4: Which kind of oxygen regulator just has one flow-rate gauge and one means to adjust it?
- regulator of peak flow.
- regulator of therapy.
- constant regulator of flow.
- regulator with high pressure. (Correct answer)
Correct answer: regulator with high pressure.
A high-pressure oxygen regulator can be designed to incorporate a single flow-rate gauge and one means to adjust it. While many systems use a separate flowmeter, some integrated high-pressure regulators combine these functions directly into the unit. This allows for direct control of the oxygen flow rate from the high-pressure source using a single control mechanism.
Question 5: Just now, you saw a patient pass out. There's no breath in him. Another savior shows up. The second duty of a rescuer is to
- start the patient's ventilation.
- automatically start applying compressions to the chest.
- Get the AED and turn on the emergency response system. (Correct answer)
- Look for a pulse.
Correct answer: Get the AED and turn on the emergency response system.
When a patient collapses, is unresponsive, and not breathing, and a second rescuer arrives, the second rescuer's primary duty is to get the AED and turn on the emergency response system. This action is crucial for early defibrillation, which significantly improves survival rates in cardiac arrest. Meanwhile, the first rescuer should continue chest compressions.
Question 6: When conducting CPR, the rescuer has the following risk of infection:
- really low. (Correct answer)
- absent.
- higher.
- moderate.
Correct answer: really low.
The risk of infection for a rescuer performing CPR is considered very low. While there is always a theoretical risk, documented cases of disease transmission during CPR are exceedingly rare, especially when proper barrier devices are used for ventilations. The benefits of performing CPR to save a life far outweigh this minimal risk.
Question 7: Five cycles, or roughly, should be included in a CPR round.
- For three minutes.
- Five minutes.
- Two minutes. (Correct answer)
- For four minutes.
Correct answer: Two minutes.
CPR guidelines recommend performing five cycles of chest compressions and ventilations, which typically takes approximately two minutes, before reassessing the patient or switching compressors. This ensures consistent, effective compressions and minimizes interruptions, which are crucial for maintaining blood flow to vital organs. Adhering to this timeframe helps optimize the chances of a positive outcome during resuscitation efforts.
Question 8: The five-year-old boy you are taking to the hospital is anxious and has a 92% oxygen saturation level. Taking an NRB or nasal cannula off his face will not sit well with him. The greatest thing for you to do is:
- Adjust the mask's straps more firmly.
- Assign the mask to the patient's mother to hold it near his face. (Correct answer)
- hold the mask against his face and look away.
- Tie the patient's hands to the stretcher to restrain them.
Correct answer: Assign the mask to the patient's mother to hold it near his face.
When a child is anxious and resistant to wearing an oxygen mask, involving a trusted caregiver like the mother can significantly improve compliance. Having the mother hold the mask near his face, rather than forcing it on, provides a sense of comfort and control for the child, making him more likely to accept the oxygen delivery. This approach prioritizes patient comfort and cooperation while still ensuring oxygen is administered effectively.
Question 9: Which of the following symptoms does not typically accompany a patient suffering from a severe airway obstruction?
- clenching the throat.
- Cyanotype.
- violent coughing fit. (Correct answer)
- unable to communicate.
Correct answer: violent coughing fit.
A patient with a severe airway obstruction typically cannot cough effectively because there isn't enough air movement to produce a strong cough. Instead, they often exhibit signs like clutching their throat, cyanosis (bluish discoloration), and an inability to speak or make sounds. A violent coughing fit is more characteristic of a mild airway obstruction where some air can still pass.
Question 10: When a patient's airway is opened in what appears to be a spinal injury, you should:
- Employ the head tilt, chin lift technique.
- Put the biting stick in.
- Apply the jaw thrust technique. (Correct answer)
- Place the patient in a lateral position.
Correct answer: Apply the jaw thrust technique.
When a spinal injury is suspected, the jaw thrust technique is the preferred method for opening the airway because it minimizes movement of the head and neck. Unlike the head tilt-chin lift, which can exacerbate a spinal injury, the jaw thrust maneuver lifts the jaw anteriorly without extending the cervical spine. This helps maintain spinal immobilization while ensuring a patent airway, which is critical for patient safety.
Question 11: A 77-year-old woman who is not breathing is the patient you are attending to. The following best describes this condition:
- anemia.
- aphasia.
- apnea. (Correct answer)
- anoxia.
Correct answer: apnea.
Apnea is the medical term for the cessation of breathing, meaning a patient is not breathing at all. Anemia refers to a lack of healthy red blood cells, aphasia is a language disorder, and anoxia is a complete lack of oxygen. Therefore, for a patient who is not breathing, apnea is the most accurate and descriptive medical term.
