CSC Airway Management & Emergency Preparedness 1 — Questions and Answers
Question 1: What is the most important initial step in airway management?
- Start IV fluids
- Check pulse
- Open the airway (Correct answer)
- Apply defibrillator pads
Correct answer: Open the airway
The most important initial step in airway management for any patient, especially one under sedation, is to ensure a patent airway. This involves maneuvers like head-tilt, chin-lift, or jaw thrust to prevent the tongue from obstructing the pharynx. Establishing an open airway is fundamental for effective breathing and oxygenation, preventing hypoxia.
Question 2: Which maneuver is used to open the airway in an unconscious patient?
- Triple airway thrust
- Head-tilt, chin-lift (Correct answer)
- Jaw massage
- Tongue depression
Correct answer: Head-tilt, chin-lift
The head-tilt, chin-lift maneuver is the most common and effective technique used to open the airway in an unconscious patient without suspected cervical spine injury. It involves tilting the head back and lifting the chin forward, which moves the tongue away from the posterior pharynx. This simple maneuver can often relieve airway obstruction caused by the tongue, restoring airflow.
Question 3: What device is commonly used for short-term oxygen delivery?
- Nasogastric tube
- Endotracheal tube
- Nasal cannula (Correct answer)
- Chest tube
Correct answer: Nasal cannula
A nasal cannula is a common and comfortable device used for short-term oxygen delivery, particularly for patients requiring low-flow supplemental oxygen. It consists of two prongs that fit into the nostrils, delivering oxygen directly into the nasal passages. This allows patients to speak, eat, and drink while receiving oxygen, making it suitable for conscious patients.
Question 4: What is a sign of airway obstruction during sedation?
- Clear breathing sounds
- Stridor or snoring (Correct answer)
- Productive cough
- Strong pulse
Correct answer: Stridor or snoring
Stridor and snoring are characteristic sounds that indicate partial airway obstruction during sedation. Snoring typically suggests obstruction at the level of the soft palate or tongue, while stridor indicates a more severe obstruction, often in the larynx or trachea. Recognizing these sounds is crucial for prompt intervention to maintain a patent airway and prevent respiratory compromise.
Question 5: What should be done first if a patient becomes unresponsive?
- Administer sedatives
- Document the incident
- Check responsiveness and alert team (Correct answer)
- Give fluids
Correct answer: Check responsiveness and alert team
If a patient becomes unresponsive during sedation, the immediate first step is to check their responsiveness by gently shaking and shouting at them. Simultaneously, the medical team should be alerted to initiate a rapid assessment and prepare for potential resuscitation. This ensures a quick and coordinated response to a potentially critical situation, prioritizing patient safety.
Question 6: Which drug reverses opioid-induced respiratory depression?
- Atropine
- Epinephrine
- Naloxone (Correct answer)
- Lidocaine
Correct answer: Naloxone
Naloxone is an opioid antagonist that specifically reverses the effects of opioid medications by blocking opioid receptors in the brain. This makes it the drug of choice for treating opioid-induced respiratory depression, a life-threatening side effect of opioid overdose or over-sedation. It rapidly restores normal breathing and consciousness by counteracting the central nervous system depressant effects of opioids.
Question 7: Which of the following is used in anaphylactic emergencies?
- Benadryl
- Epinephrine (Correct answer)
- Oxygen
- Normal saline
Correct answer: Epinephrine
Epinephrine is the first-line treatment for anaphylaxis due to its rapid and potent vasoconstrictive and bronchodilatory effects. It quickly counteracts the severe symptoms of anaphylaxis, such as airway swelling, bronchospasm, and hypotension, by relaxing airway muscles and constricting blood vessels. Administering epinephrine promptly can be life-saving in these severe allergic reactions.
Question 8: What is the most reliable method of confirming endotracheal tube placement?
- Chest auscultation
- Fog in tube
- Capnography (Correct answer)
- Oxygen saturation
Correct answer: Capnography
Capnography measures the carbon dioxide levels in exhaled breath, providing real-time, continuous confirmation of proper endotracheal tube (ETT) placement in the trachea. The presence of end-tidal CO2 indicates that the tube is correctly positioned in the airway and not in the esophagus. While other methods like auscultation are used, capnography is considered the most reliable and definitive method for confirming ETT placement.
Question 9: Which is a key component of emergency preparedness?
- A locked storage room
- Crash cart with supplies (Correct answer)
- Medical textbooks
- Only CPR certification
Correct answer: Crash cart with supplies
A crash cart, also known as an emergency cart, is a mobile unit containing essential medications, equipment, and supplies needed for medical emergencies. Having a well-stocked and readily accessible crash cart is a critical component of emergency preparedness in any healthcare setting. It ensures that providers can quickly respond to life-threatening situations and provide immediate, life-saving care.
