What is most helpful to determine the need for intubation?
- A.
ABG
- B.
Clinical assessment
- C.
Lung auscultation
- D.
Pulse oximetry alone
- E.
Testing the gag reflex
Correct Answer
B. Clinical assessmentExplanation
Clinical assessment is the most helpful in determining the need for intubation. This is because clinical assessment involves evaluating the patient's overall condition, including their respiratory effort, mental status, oxygenation, and airway patency. It allows healthcare providers to assess the severity of respiratory distress and determine if intubation is necessary to maintain adequate oxygenation and ventilation. Other options such as ABG, lung auscultation, pulse oximetry, and testing the gag reflex may provide additional information, but clinical assessment encompasses a comprehensive evaluation of the patient's condition.Rate this question:

You can predict relatively easy intubation in a patient who:
- A.
Has a receding mandible
- B.
Has a short neck
- C.
Has no teeth
- D.
Has prominent upper incisors
- E.
Is immobilized due to potential neck trauma
Correct Answer
C. Has no teethExplanation
Patients who have no teeth have a higher likelihood of easy intubation because the absence of teeth allows for better visualization and access to the airway. Teeth can obstruct the view and make it difficult to insert the endotracheal tube. Therefore, in patients without teeth, intubation can be performed more easily and with less risk of complications.Rate this question:

You can safely manage the airway in a patient with suspected cervical spine injury by using:
- A.
Chin lift
- B.
Direct tongue depression
- C.
Head tilt
- D.
Jaw thrust
- E.
None of the above
Correct Answer
D. Jaw thrustExplanation
The jaw thrust maneuver is the safest way to manage the airway in a patient with suspected cervical spine injury. This technique involves placing the fingers behind the angle of the jaw and lifting the jaw forward, which helps to open the airway without flexing or extending the neck. By using the jaw thrust maneuver, the healthcare provider can maintain proper alignment of the cervical spine and minimize the risk of further injury. The other options mentioned, such as chin lift, direct tongue depression, and head tilt, may potentially cause movement or manipulation of the cervical spine, which could worsen the injury.Rate this question:

- A.
Prior neck surgery
- B.
Hematoma, tumor, or abscess on the neck
- C.
Scarring from radiation on the neck
- D.
Obesity
- E.
Class III or Class IV Mallampati
Correct Answer
E. Class III or Class IV MallampatiExplanation
Difficulty with cricothyrotomy can be anticipated with all of the following except Class III or Class IV Mallampati. Mallampati classification is a method used to assess the ease of intubation based on the visibility of the patient's tonsils and uvula. Class III or Class IV Mallampati indicates a difficult airway, which can make cricothyrotomy more challenging. Prior neck surgery, hematoma, tumor, or abscess on the neck, scarring from radiation on the neck, and obesity can all contribute to anatomical difficulties during cricothyrotomy.Rate this question:

All of the following indicate difficult extra-glottic device (EGD) placement EXCEPT:
- A.
Suspected cervical spine injury
- B.
Restricted mouth opening
- C.
Stiffness (resistance to ventilation)
- D.
Obstruction or obesity
- E.
Distorted anatomy
Correct Answer
A. Suspected cervical spine injuryExplanation
Suspected cervical spine injury is not a factor that indicates difficult extra-glottic device (EGD) placement. Difficult EGD placement can be influenced by factors such as restricted mouth opening, stiffness (resistance to ventilation), obstruction or obesity, and distorted anatomy. However, a suspected cervical spine injury does not directly affect the placement of an EGD.Rate this question:

Etomidate
- A.
Phencyclidine derivative
- B.
Increases intracranial pressure
- C.
Causes hypotension
- D.
Never causes myoclonus
- E.
Induction dose is 0.3mg/kg IV.
Correct Answer
E. Induction dose is 0.3mg/kg IV.Explanation
Etomidate is a medication used for induction of anesthesia. The correct answer states that the induction dose of etomidate is 0.3mg/kg IV. This means that when administering etomidate for anesthesia induction, the recommended dose is 0.3 milligrams per kilogram of the patient's body weight, given intravenously. This information is important for healthcare professionals who are responsible for administering anesthesia and need to ensure that the correct dose of etomidate is given to achieve the desired effect.Rate this question:

10. All are true of Ketamine EXCEPT:
- A.
Can increase intracranial pressure
- B.
Bronchoconstrictor
- C.
Can increase blood pressure
- D.
Can cause an emergence phenomenon (frightening dreams)
- E.
1-2mg/kg produces loss of awareness within 30 seconds, peaks in 1 minute, and lasts 10-15 minutes.
Correct Answer
B. BronchoconstrictorExplanation
Ketamine is a dissociative anesthetic that is commonly used for induction and maintenance of anesthesia. It is known to have bronchodilator properties, meaning it relaxes the smooth muscles of the airways and helps to open up the bronchial tubes. This makes it a useful option for patients with asthma or other respiratory conditions. Therefore, the statement that ketamine is a bronchoconstrictor is incorrect.Rate this question:

Which should be avoided when intubating a status asthmaticus?
- A.
Thiopental
- B.
Ketamine
- C.
Midazolam
- D.
Etomidate
Correct Answer
A. ThiopentalExplanation
Thiopental should be avoided when intubating a status asthmaticus because it is a barbiturate that can cause respiratory depression. In status asthmaticus, the patient already has compromised lung function and any further respiratory depression can worsen their condition. Therefore, it is important to avoid medications that can further suppress the respiratory drive, such as thiopental.Rate this question:

- B.
The clinical duration of action of succinylcholine before spontaneous respirations occurs is 20 minutes.
- C.
Use of 0.5 mg/kg of succinylcholine results in both less fasiculations and less myalgias than occur with 1mg/kg.
- D.
Succinylcholine has been associated with masseter spasm and malignant hyperthermia.
- E.
Succinylcholine is contraindicated in renal failure, acute burns, strokes and spinal cord injuries because of its propensity to cause hyperkalemia.
Correct Answer
D. Succinylcholine has been associated with masseter spasm and malignant hyperthermia.Explanation
Succinylcholine has been associated with masseter spasm and malignant hyperthermia. This means that the use of succinylcholine can lead to involuntary contraction of the masseter muscle, causing difficulty in opening the mouth. It is also associated with a rare but potentially life-threatening condition called malignant hyperthermia, which is characterized by a rapid rise in body temperature and severe muscle contractions. These adverse effects of succinylcholine are important considerations when using this medication in clinical practice.Rate this question:

Contraindications to nasotracheal intubation in a trauma patient include
- A.
Cervical spine fracture
- B.
Apnea
- C.
Depressed mental status
- D.
Hypotension
- E.
Pneumothorax
Correct Answer
B. ApneaExplanation
Apnea is a contraindication to nasotracheal intubation in a trauma patient because during the procedure, the patient's airway is temporarily blocked, and if the patient is already experiencing apnea (the absence of breathing), this can lead to a further decrease in oxygen levels and potentially worsen their condition. It is important to ensure that the patient has a stable respiratory status before attempting nasotracheal intubation to prevent any complications.Rate this question:

- B.
Awake intubation may be done by the nasotracheal route.
- C.
Care should be taken before intubation to assess the airway for ease of ventilation as well as intubation.
- D.
Cricothyrotomy is the crucial rescue procedure when intubation and ventilation fail.
- E.
All of the above are true.
Correct Answer
E. All of the above are true.Explanation
The correct answer is "All of the above are true." This means that all of the statements mentioned in the question are correct. Airways such as the laryngeal mask airway and esophageal obturator airway are indeed available in the event of a failed airway. Awake intubation can be done by the nasotracheal route. Before intubation, it is important to assess the airway for ease of ventilation as well as intubation. In cases where intubation and ventilation fail, cricothyrotomy is considered the crucial rescue procedure.Rate this question:

Predicted difficulties during intubation with a fiberoptic bronchoscope include:
- A.
Bleeding in the airway
- B.
Cervical spine injury
- C.
Epiglottitis
- D.
Limited mouth opening
- E.
Protuberant teeth
Correct Answer
A. Bleeding in the airwayExplanation
During intubation with a fiberoptic bronchoscope, bleeding in the airway can be a predicted difficulty. This is because the insertion of the bronchoscope into the airway can cause trauma to the delicate tissues, leading to bleeding. This can obstruct the view and make it challenging to navigate the bronchoscope properly. Additionally, excessive bleeding can also compromise the patient's oxygenation and ventilation, further complicating the intubation process. Therefore, it is important for the healthcare provider to be prepared for this potential difficulty and have appropriate measures in place to manage bleeding if it occurs.Rate this question:

Contraindication to cricothyrotomy include:
- A.
Acute airway obstruction
- B.
Age younger than 10 years
- C.
Apnea
- D.
Inability to orotracheally or digitally intubate
- E.
Severe facial trauma
Correct Answer
B. Age younger than 10 yearsExplanation
Cricothyrotomy is a procedure used to establish a temporary airway in cases of severe airway obstruction. It involves making an incision in the cricothyroid membrane to access the airway. However, performing cricothyrotomy in children younger than 10 years old is not recommended due to anatomical differences in the airway. The cricothyroid membrane in younger children is smaller and more difficult to access, making the procedure riskier and potentially ineffective. Therefore, age younger than 10 years is a contraindication to cricothyrotomy.Rate this question:

When using rapid sequence intubation to place an endotracheal tube, which of the following medication should be used for paralysis:
- A.
Etomidate
- B.
Ketamine
- C.
Propofol
- D.
Rocuronium
- E.
Thiopental
Correct Answer
D. RocuroniumExplanation
Rocuronium should be used for paralysis during rapid sequence intubation. Rocuronium is a non-depolarizing neuromuscular blocking agent that causes skeletal muscle relaxation and paralysis. It is commonly used in emergency intubation because it has a rapid onset of action and a relatively short duration of effect. This allows for quick and effective intubation while minimizing the risk of complications. Etomidate, ketamine, propofol, and thiopental are all sedative agents used for induction of anesthesia, but they do not provide paralysis.Rate this question:

In an asthmatic patient who requires intubation:
- A.
Inspiratory to expiratory ration should be kept at 1:2, and 14 breaths/minute
- B.
Ketamine is the preferred paralytic agent
- C.
Nasotracheal intubation is preferred over orotracheal
- D.
Propofol can be used as a sedating agent
- E.
Tidal volume should be kept at 10mL/kg ideal body weight.
Correct Answer
D. Propofol can be used as a sedating agentExplanation
Propofol can be used as a sedating agent in an asthmatic patient who requires intubation. This is because propofol is a short-acting sedative-hypnotic agent that provides rapid onset and offset of sedation, allowing for better control of the patient's airway. It has bronchodilatory properties and does not cause histamine release, making it a suitable choice for asthmatic patients. Additionally, propofol has antiemetic effects, which can be beneficial in preventing aspiration during intubation.Rate this question:

- C.
Reasonable initial ventilatory settings are a TV of 12ml/kg body mass and a rate of 16 breaths/minute.
- D.
PEEP should be initiated at 15cm H2O
- E.
Bradycardia and ventricular irritability represents oxygen toxicity.
Correct Answer
A. Tachycardia and hypertension can indicate ventilatory intolerance and a need for increased sedation or adjustment of ventilatory settings.Explanation
Tachycardia and hypertension can indicate that the patient is not tolerating the ventilator settings and may need more sedation or adjustment of the ventilatory settings. This means that the patient's heart rate and blood pressure are elevated, which could be a sign of distress or discomfort caused by the ventilator. Increasing sedation or adjusting the ventilatory settings can help alleviate these symptoms and improve the patient's comfort and tolerance to the ventilator.Rate this question:
