    • C.

      Vocal Cords

    • D.

      Trachea

    Correct Answer
    D. Trachea
    Explanation
    The diagram represents a human respiratory system. The esophagus is responsible for carrying food to the stomach and is not a part of the respiratory system. Turbinates are bony structures in the nasal cavity that help to filter and humidify the air but are not directly related to the trachea. Vocal cords are located within the larynx and are responsible for producing sound, but they are not the same as the trachea. The trachea, also known as the windpipe, is the tube that connects the larynx to the bronchi and allows air to pass in and out of the lungs. Therefore, the correct answer is Trachea.

    Rate this question:

  • 25. 

      For rapid sequence intubation, what is the correct sequence of actions?

    • A.

      Denitrogenate/oxygenate -- give STP and then 5 min later SCh IV push -- cricoid pressure -- bag ventilate

    • B.

      Give STP and SCh IV push -- oxygenate -- cricoid pressure -- no bag ventilation -- intubate

    • C.

      Denitrogenate/oxygenate -- give STP and SCh IV push at same time -- cricoid pressure -- dont bag-ventilate, instead intubate right away

    • D.

      STP and SCh -- oxygenate -- cricoid pressure -- intubate

    Correct Answer
    C. Denitrogenate/oxygenate -- give STP and SCh IV push at same time -- cricoid pressure -- dont bag-ventilate, instead intubate right away
    Explanation
    The correct sequence of actions for rapid sequence intubation is to denitrogenate/oxygenate the patient, followed by giving succinylcholine (STP) and a rapid IV push of a sedative agent at the same time. Then, apply cricoid pressure and proceed to intubate the patient without bag-ventilating. This sequence aims to ensure optimal conditions for intubation while minimizing the risk of aspiration.

    Rate this question:

  • 26. 

    For RSI, maximum allowable pressure we can bag-ventilate patient is 20cm H2O.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The maximum allowable pressure we can bag-ventilate a patient with RSI is not 20cm H2O. The correct answer is False, indicating that the statement is incorrect. The actual maximum allowable pressure for bag-ventilation may vary depending on the specific patient and their condition, but it is generally recommended to keep the pressure below 20cm H2O to avoid potential complications.

    Rate this question:

  • 27. 

    You are about to intubate your patient and you put your patients head in the "sniff position". This entails...

    • A.

      Aligning the oral axis, laryngeal axis and the pharyngeal axis in a perpendicular axis as much as possible

    • B.

      Aligning the oral, pharyngeal, and laryngeal axis with the roof of the mouth

    • C.

      Aligning the oral, pharyngeal, and laryngeal axis as close to each as possible

    Correct Answer
    C. Aligning the oral, pharyngeal, and laryngeal axis as close to each as possible
    Explanation
    The "sniff position" in intubation involves aligning the oral, pharyngeal, and laryngeal axis as close to each other as possible. This positioning helps to optimize the visualization of the vocal cords and facilitate the passage of the endotracheal tube into the trachea. By aligning these axes, the airway is straightened, allowing for easier insertion of the tube and reducing the risk of complications during intubation.

  • 28. 

    Which one is not an appropriate intervention for a patient experiencing a laryngospasm?

    • A.

      Administer a higher amount of sevoflurane, as it is a potent bronchodilator

    • B.

      Provide patient with 100% FiO2, jaw thrust, and positive pressure

    • C.

      Administer Succinylcholine 10-20mg IV

    Correct Answer
    A. Administer a higher amount of sevoflurane, as it is a potent bronchodilator
    Explanation
    Administering a higher amount of sevoflurane is not an appropriate intervention for a patient experiencing a laryngospasm. Sevoflurane is a volatile anesthetic that can induce or worsen laryngospasm. Increasing the concentration of sevoflurane would not help in relieving the laryngospasm and may even exacerbate the condition.

  • 29. 

    A patient who is difficult to intubate is brought to the OR. Optimal conditions were met for intubation (positioning, drugs, difficult airway cart available, etc). After the first failed attempt at intubation, you are allowed to practice your excellent bag-mask ventilation. After a total of three failed intubation attempts, you are now unable to bag-mask ventilate your patient. You reposition the head and still not able to ventilate. Your CRNA/MDA is also not able to effectively bag-mask the patient. What do you expect will be the next course of action?

    • A.

      Surgical Airway

    • B.

      Blind insertion of an LMA. You do not need a direct view.

    • C.

      Insert a nasal airway, since you cannot insert an oral airway.

    Correct Answer
    A. Surgical Airway
    Explanation
    The next course of action would be to perform a surgical airway. This is necessary because the patient is difficult to intubate and cannot be effectively bag-mask ventilated even after repositioning the head. A surgical airway provides a direct and secure route for oxygenation and ventilation when other methods have failed. Blind insertion of an LMA or inserting a nasal airway would not be sufficient in this situation.

    Mallampati class 3 refers to a specific classification system used to assess the difficulty of intubation in patients. Class 3 indicates that the soft palate and the base of the uvula are visible, while the tonsillar pillars and the pharyngeal walls are not. This suggests that intubation may be moderately difficult in these patients.

    All of the following are effective ways to decrease the risk for aspiration EXCEPT...

    • A.

      Increase gastric Ph

    • B.

      Rapid Sequence Induction

    • C.

      Deep extubation

    • D.

      Increase gastric Motility

    Correct Answer
    C. Deep extubation
    Explanation
    Deep extubation refers to the removal of an endotracheal tube while the patient is still under anesthesia and unconscious. This technique is not effective in decreasing the risk for aspiration because it does not address the factors that contribute to aspiration, such as gastric pH or motility. In fact, deep extubation may increase the risk for aspiration as it can lead to inadequate airway protection and the potential for regurgitation of gastric contents. Therefore, deep extubation is the exception among the given options as an effective way to decrease the risk for aspiration.

    What method is most reliable in confirming immediate tracheal intubation?

    • A.

      Chest Xray

    • B.

      ETCO2

    • C.

      Fogging of ETT

    • D.

      Visualization of chest rising

    Correct Answer
    B. ETCO2
    Explanation
    ETCO2, or end-tidal carbon dioxide monitoring, is the most reliable method in confirming immediate tracheal intubation. This method measures the concentration of carbon dioxide at the end of each exhaled breath, providing real-time feedback on the placement of the endotracheal tube (ETT). If the ETT is properly placed in the trachea, it will allow for the exhaled carbon dioxide to be detected, indicating successful intubation. This method is considered more reliable than other options such as chest X-ray, fogging of ETT, or visualization of chest rising, as it provides direct and immediate confirmation of tracheal intubation.

    Identify the patient at risk for aspiration:

    • A.

      40 y/o male with shoulder injury

    • B.

      20 y/o emergency appendectomy

    • C.

      60 y/o bilateral inguinal hernia

    • D.

      50 y/o hypertensive patient who took his BP meds with sips of H2O

    Correct Answer
    B. 20 y/o emergency appendectomy
    Explanation
    A patient who has undergone an emergency appendectomy is at risk for aspiration. This is because the surgery may have caused anesthesia or sedation, which can impair the patient's ability to protect their airway and swallow properly. Additionally, the surgical procedure itself may have caused inflammation or trauma to the throat or esophagus, making it difficult for the patient to swallow effectively. Aspiration occurs when food, liquid, or saliva enters the airway instead of going down the esophagus, which can lead to serious complications such as pneumonia.

    Which of the following characterisics may be difficult to mask ventilate?

    • A.

      Beard

    • B.

      Endentulous

    • C.

      CPAP at home

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    All of the above characteristics may be difficult to mask ventilate. A beard can interfere with the proper seal of the mask, leading to air leakage and difficulty in maintaining adequate ventilation. Edentulous patients (those without teeth) may have a poorly fitting mask due to lack of support from the teeth, resulting in air leakage and difficulty in achieving effective ventilation. CPAP at home indicates that the patient may have an underlying respiratory condition that requires continuous positive airway pressure, which can make mask ventilation challenging as the patient may be dependent on the CPAP machine for adequate ventilation.

    What is the indication for a Rapid Sequence Induction? (RSI)

    • A.

      Surgeon is scrubbed in and is awaiting anxiously for you to intubate

    • B.

      Pt is obese and has a history of GERD

    • C.

      Pt can’t tolerate laying down flat and must induce fast

    • D.

      Pt is anxious and must induce fast

    Correct Answer
    B. Pt is obese and has a history of GERD
    Explanation
    The indication for a Rapid Sequence Induction (RSI) in this case is that the patient is obese and has a history of GERD. RSI is a technique used to quickly secure the patient's airway in situations where there is a high risk of aspiration, such as in patients with GERD. Obesity can also increase the risk of aspiration and make intubation more challenging. Therefore, in this scenario, the patient's obesity and history of GERD make RSI the appropriate choice to ensure a safe and efficient intubation.

    Which is NOT a contraindication of the use of a LMA?

    • A.

      Lithotomy position

    • B.

      Trauma case requiring fast intubation

    • C.

      Patient at 26 weeks gestation

    • D.

      MAC case requiring no neuro-muscular blockade

    Correct Answer
    D. MAC case requiring no neuro-muscular blockade
    Explanation
    The use of a LMA (Laryngeal Mask Airway) is contraindicated in certain situations, but a MAC (Monitored Anesthesia Care) case requiring no neuro-muscular blockade is not one of them. A LMA can be used in this case because it does not require the use of muscle relaxants. In contrast, the other options listed can be contraindications for using a LMA. The lithotomy position may cause airway obstruction, a trauma case requiring fast intubation may require a secure airway with an endotracheal tube, and a patient at 26 weeks gestation may have a higher risk of aspiration, making a LMA unsuitable.

    What is the Murphy Eye?

    • A.

      The view seen when looking through a laryngoscope

    • B.

      One of the single unpaired cartilages in the larynx

    • C.

      A side vent near the distal end of an endotracheal tube

    • D.

      A modification of the atlanto-occipital position

    Correct Answer
    C. A side vent near the distal end of an endotracheal tube
    Explanation
    The Murphy Eye refers to a side vent that is located near the distal end of an endotracheal tube. This vent allows for the passage of air even if the main opening of the tube becomes blocked or occluded. This feature ensures that the patient's airway remains open and allows for the delivery of oxygen or anesthesia during medical procedures.

    How is laryngospasm treated?

    • A.

      Immediate dose of rocuronium to relax all muscles

    • B.

      Aggressive positive pressure to pry open the cords

    • C.

      Administration of succinycholine 10-20 mg

    • D.

      Call for help, you have never done this before

    Correct Answer
    C. Administration of succinycholine 10-20 mg
    Explanation
    Succinycholine is a medication that is commonly used to induce muscle relaxation during certain medical procedures. In the case of laryngospasm, where the vocal cords involuntarily close, the administration of succinycholine can help to relax the muscles in the throat and open up the airway. This can alleviate the symptoms of laryngospasm and allow for normal breathing to resume. It is important to note that this medication should only be administered by trained medical professionals.

    Which of the following would not put pt at risk for difficult airway?

    • A.

      Wide Palate

    • B.

      Pregnancy

    • C.

      Pt wearing a Halo

    • D.

      Thyromental distance

    Correct Answer
    A. Wide Palate
    Explanation
    A wide palate would not put a patient at risk for a difficult airway because it refers to the width of the roof of the mouth, which does not directly affect the airway. Pregnancy, wearing a Halo device, and thyromental distance can all potentially contribute to a difficult airway.

    You are looking for an airway adjunct to use on your pt who is very lightly sedated. You have just extubated the pt and they are still having a little trouble keeping the airway clear. You do not want to stimulate the gag reflex. What would be best to use?

    • A.

      Oral airway

    • B.

      Re-intubate until more awake

    • C.

      Nasal Airway

    • D.

      Nasal Cannula 2L O2

    Correct Answer
    C. Nasal Airway
    Explanation
    In this scenario, the patient is lightly sedated and having trouble keeping the airway clear after extubation. The best option would be to use a nasal airway. Nasal airways are used to maintain a patent airway by preventing the tongue from obstructing the pharynx. They are well-suited for patients who are lightly sedated as they do not stimulate the gag reflex like oral airways. Re-intubating the patient until they are more awake would be an invasive and unnecessary procedure. Nasal cannula 2L O2 is used to deliver supplemental oxygen and would not address the issue of maintaining a clear airway.

    You are assisting on a D&C for Mrs. Wong who is 5'7" and weighs 75 kg. This is a short procedure with no need for neuromuscular blockade. What size LMA would you choose?

    • A.

      Size 3

    • B.

      Size 2.5

    • C.

      Size 4

    • D.

      Size 5

    • E.

      None, use ETT for this pt.

    Correct Answer
    D. Size 5
    Explanation
    Based on Mrs. Wong's height and weight, a size 5 LMA would be the most appropriate choice. The size of the LMA is determined by the patient's weight and height, and a size 5 LMA is typically recommended for patients weighing around 75 kg. Since this is a short procedure and neuromuscular blockade is not required, using a size 5 LMA would provide adequate airway management for Mrs. Wong.
