    What size ETT would be most appropriate for an adult male?

    • 8 mm

    • 7 mm

    • 6 mm

    • 10 mm

    Correct Answer
    A. 8 mm
    Explanation
    An endotracheal tube (ETT) is a tube inserted into the trachea to maintain an open airway during surgery or respiratory distress. The most appropriate size for an adult male would be 8 mm. This size is commonly used for adult males as it allows for adequate ventilation and oxygenation while minimizing the risk of complications such as tube obstruction or air leak. Sizes smaller than 8 mm may not provide sufficient airflow, while sizes larger than 8 mm may increase the risk of trauma or damage to the airway.

    Prior to intubating a pt you should...

    • HyperVentilate

    • HyperNitrogenate

    • Allow CO2 to rise

    • HyperOxygenate

    Correct Answer
    A. HyperOxygenate
    Explanation
    Prior to intubating a patient, it is important to hyperoxygenate them. This involves providing high levels of oxygen to the patient to ensure that their blood is well saturated with oxygen before the procedure. Hyperoxygenation helps to prevent hypoxemia during intubation, which can occur when the patient's oxygen levels drop too low. By hyperoxygenating the patient, the healthcare provider can ensure that there is an adequate oxygen reserve in the patient's body, reducing the risk of complications during the intubation process.

    • Vestibular Fold (False cords)

    Correct Answer
    A. Vestibular Fold (False cords)
    Explanation
    The diagram is likely showing a cross-section of the larynx, which is the part of the throat involved in producing sound. The vestibular fold, also known as the false cords, are located above the vocal cords. They do not directly participate in sound production but help protect the vocal cords and assist in controlling airflow during speech and swallowing. Therefore, D in the diagram is most likely representing the vestibular fold (false cords).

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

    • Beard

    • Endentulous

    • CPAP at home

    • All of the above

    Correct Answer
    A. 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.

    Which of the following is a risk associated with high pressure ETT cuffs?

    • Increase risk for Sore throat

    • Spontaneous extubation

    • More ischemic damage to tracheal mucosa

    • Increase risk for aspiration

    Correct Answer
    A. More ischemic damage to tracheal mucosa
    Explanation
    High pressure ETT cuffs can lead to more ischemic damage to the tracheal mucosa. When the cuff is inflated with high pressure, it can compress the blood vessels in the tracheal wall, reducing blood flow and causing ischemia. This can result in tissue damage and potential complications such as tracheal stenosis or necrosis. It is important to maintain an appropriate cuff pressure to minimize the risk of ischemic damage and ensure patient safety during intubation.

    What size ETT would commonly pick for an adult female?

    • 8.5 mm

    • 6 mm

    • 3 mm

    • 7.5 mm

    Correct Answer
    A. 7.5 mm
    Explanation
    An ETT (endotracheal tube) is a device used to secure a patient's airway during anesthesia or in critical care settings. When selecting the size of an ETT for an adult female, a commonly chosen size is 7.5 mm. This size is suitable for most adult females as it allows for proper ventilation and oxygenation while maintaining a secure airway. Sizes such as 8.5 mm may be used for larger individuals, while smaller sizes like 6 mm or 3 mm would typically be too small for an adult female.

    How far would you plan to insert an ETT in a 64 yr old woman?

    • 12 cm

    • 21 cm

    • 17 cm

    • 25 cm

    Correct Answer
    A. 21 cm
    Explanation
    An endotracheal tube (ETT) is a tube inserted into the trachea to assist with breathing. The length of the ETT that needs to be inserted depends on the patient's age and gender. In this case, the question specifies that the patient is a 64-year-old woman. The average distance from the vocal cords to the carina (the point where the trachea splits into the bronchi) in an adult woman is around 21 cm. Therefore, to properly insert the ETT in this 64-year-old woman, a length of 21 cm would be appropriate.

    A previously healthy male present with an open femur fracture from an MVA and needs to be repaired under GA. He is on a backboard with cervical collar in place. What  should the plan be?

    • Remove the neck collar and intubate as usual

    • Avoid GA and perform a regional block for the procedure

    • Intubate with a technique that does not require neck movement

    Correct Answer
    A. Intubate with a technique that does not require neck movement
    Explanation
    The correct answer is to intubate with a technique that does not require neck movement. This is because the patient has an open femur fracture and needs to be repaired under general anesthesia (GA). However, the patient is on a backboard with a cervical collar in place, which restricts neck movement. Therefore, intubating with a technique that does not require neck movement would be the safest approach to avoid further injury to the patient's neck.

    Rate this question:

  • 17. 

    According to Dr. Groom’s lecture, what is the MOST reliable way to check ETT placement?

    • Chest Rise

    • Breath Sound

    • ETCO2 wave form

    • SaO2

    Correct Answer
    A. ETCO2 wave form
    Explanation
    The ETCO2 wave form is the most reliable way to check ETT (endotracheal tube) placement. End-tidal carbon dioxide (ETCO2) monitoring provides a continuous measurement of carbon dioxide levels in exhaled breath. When the ETT is properly placed in the trachea, the ETCO2 wave form will show a consistent and regular waveform. If the ETT is misplaced in the esophagus or bronchus, the ETCO2 waveform will be absent or irregular. This method is considered more reliable than assessing chest rise, breath sounds, or SaO2 levels for confirming correct ETT placement.

    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?

    • Oral airway

    • Re-intubate until more awake

    • Nasal Airway

    • Nasal Cannula 2L O2

    Correct Answer
    A. 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.

    • Cricoid Cartilage

    • Glottic Opening

    Correct Answer
    A. Cricothyroid membrane
    Explanation
    The correct answer is the cricothyroid membrane. The cricothyroid membrane is a thin, elastic structure located between the cricoid cartilage and the thyroid cartilage in the larynx. It plays a crucial role in phonation by connecting the cricoid and thyroid cartilages and allowing for the adjustment of vocal pitch. When the cricothyroid muscle contracts, it stretches the cricothyroid membrane, causing the vocal folds to tighten and vibrate, producing sound. Therefore, the cricothyroid membrane is an essential component of the vocal apparatus.

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

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

    • Pt is obese and has a history of GERD

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

    • Pt is anxious and must induce fast

    Correct Answer
    A. 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.

    What affect does the administration of Nitrous Oxide have on the volume of the cuff of an inflated endotracheal tube?

    • Deflates Cuff

    • Inflates Cuff

    • Has minimal effect on cuff

    Correct Answer
    A. Inflates Cuff
    Explanation
    The administration of Nitrous Oxide inflates the cuff of an inflated endotracheal tube. Nitrous Oxide is a gas that is commonly used as an anesthetic during surgery. When it is administered, it can cause an increase in pressure within the cuff, leading to its inflation. This helps to create a seal between the endotracheal tube and the trachea, preventing any air leakage and ensuring proper ventilation during the procedure.

    In the above diagram, what is I?

    • Esophagus

    • Turbinates

    • Vocal Cords

    • Trachea

    Correct Answer
    A. 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.

    According the manufacturer, which of the following is appropriate regarding insertion of an LMA?

    • Insert the LMA completely deflated and only inflate once it is in place within the airway

    • Secure the LMA 3cm to right of the midline once it is in place.

    • Insert LMA fully inflated and just slide into place.

    • Provide plenty of lubrication both in front and back of airway to facilitate insertion.

    Correct Answer
    A. Insert the LMA completely deflated and only inflate once it is in place within the airway
    Explanation
    The correct answer states that the LMA should be inserted completely deflated and only inflated once it is in place within the airway. This is appropriate because inserting the LMA fully inflated may cause difficulty in placement and may lead to trauma or damage to the airway. By inserting it deflated, it can be easily maneuvered into the correct position, and then inflated to create a seal. This ensures proper placement and reduces the risk of complications.

    A major difference in a patient with deep and lightly anesthetized patient is the response to suctioning.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A major difference between a deep and lightly anesthetized patient is their response to suctioning. In a deep anesthetized patient, they are less likely to respond to suctioning due to the deeper level of anesthesia. On the other hand, a lightly anesthetized patient may have a more pronounced response to suctioning as they are not as deeply sedated. This difference in response to suctioning is an important consideration for healthcare professionals when managing patients under anesthesia.

    In the above diagram, Identify 8.

    • Thyrohyoid membrane

    • Cricothyroid Muscles

    • Cricothyroid Ligament

    • Cricoid Cartilage

    Correct Answer
    A. Cricothyroid Ligament
    Explanation
    The correct answer is the cricothyroid ligament. The cricothyroid ligament is a thin, strong band of fibrous tissue that connects the cricoid cartilage to the thyroid cartilage. It helps to stabilize the joint between these two cartilages and allows for movement and tension adjustment of the vocal cords. The cricothyroid ligament plays a crucial role in phonation and voice production.

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

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

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

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

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

    Correct Answer
    A. 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.

    In the above diagram, what is K?

    • Cricoid Cartilage

    • Cricothyroid membrane

    • Thyroid Cartilage

    • Vocal Cords

    Correct Answer
    A. Cricoid Cartilage
    Explanation
    The correct answer is Cricoid Cartilage. The cricoid cartilage is a ring-shaped structure located in the lower part of the larynx, just below the thyroid cartilage. It is the only complete ring of cartilage in the larynx and provides support and protection to the vocal cords. The cricoid cartilage also plays a role in regulating the tension of the vocal cords, allowing for changes in pitch and volume during speech and singing.

    Identify the patient at risk for aspiration:

    • 40 y/o male with shoulder injury

    • 20 y/o emergency appendectomy

    • 60 y/o bilateral inguinal hernia

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

    Correct Answer
    A. 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.

    You are looking for an LMA that will allow you to insert an NGT easily. Which specialized LMA might you pick?

    • Proseal LMA

    • Classic

    • FastTrach

    • FiberOptic

    Correct Answer
    A. Proseal LMA
    Explanation
    The Proseal LMA is a specialized LMA that is designed to provide a secure seal and allow for easy insertion of an NGT (Nasogastric Tube). It features a cuff that inflates to create a seal around the larynx, preventing aspiration. The Proseal LMA also has a gastric access port that allows for easy insertion of an NGT into the stomach. This makes it an ideal choice for the given scenario where the goal is to insert an NGT easily.

    Which pt would not be at an increased risk for aspiration?

    • Mrs. Luiz who states she had a little sip of water this morning from a dixie cup to take her pills.

    • Mr. Rogers, an emergency Crani coming from the trauma bay to the OR.

    • Ms. Minns who is obese and has a history of GERD

    • Mr. Jerkface who has no prior medical history, has been chewing gum and munching on ice cubes to lessen his hunger from being NPO.

    Correct Answer
    A. Mrs. Luiz who states she had a little sip of water this morning from a dixie cup to take her pills.
    Explanation
    Mrs. Luiz would not be at an increased risk for aspiration because she only had a small sip of water from a dixie cup to take her pills. Aspiration is the inhalation of foreign material into the airways, such as food or liquids, which can lead to lung infections or other complications. In this case, Mrs. Luiz's small sip of water is unlikely to cause aspiration compared to the other options.
