Which of the following is a likely occurrence when using an endotracheal intubation to secure the airway
- A.
Gastric distention is more likely
- B.
Complete airway control is achieved
- C.
The tracheal suctioning becomes more complicated
- D.
Medications can be longer be introduced into the trachea
- E.
It makes obtaining a good mask seal more difficult
Correct Answer
B. Complete airway control is achievedExplanation
When using an endotracheal intubation to secure the airway, complete airway control is likely to be achieved. Endotracheal intubation involves inserting a tube into the trachea, bypassing the upper airway, to ensure a patent airway and facilitate mechanical ventilation. This procedure provides a direct route for oxygenation and ventilation, allowing for better control of the airway compared to other methods. It is a reliable method to secure the airway and is commonly used during surgeries or in critically ill patients.Rate this question:

The pattern of light that indicates that the lighted stylet is in the proper position to advance the endotracheal tube when performing transillumination intubation is
- A.
A very dim and diffuse light
- B.
A circle of light at the adam's apple
- C.
light on either side of the adam's apple
Correct Answer
B. A circle of light at the adam's appleExplanation
During transillumination intubation, a circle of light at the adam's apple indicates that the lighted stylet is in the proper position to advance the endotracheal tube. This pattern of light suggests that the endotracheal tube can be safely inserted into the trachea, ensuring proper intubation. The circle of light at the adam's apple serves as a visual guide for healthcare professionals, indicating the correct placement of the endotracheal tube.Rate this question:

Altered mental status with risk of aspiration
- C.
Acute disorder threatening the airway
- D.
Glasgow coma scale of 8 or less
- E.
All the above
Correct Answer
E. All the aboveExplanation
Rapid-sequence intubation is a procedure used to secure a patient's airway quickly and safely. It is indicated in several situations, including impending respiratory failure, altered mental status with the risk of aspiration, and acute disorders that threaten the airway. The Glasgow Coma Scale of 8 or less is also an indication for rapid-sequence intubation. Therefore, the correct answer is "all the above."Rate this question:

Which of the following is NOT a paralytic agent used for rapid sequence intubation
- A.
Succinylcholine
- B.
Midazolam
- C.
Vercuronium
- D.
Attacruium
- E.
Pancuronium
Correct Answer
B. MidazolamExplanation
The correct answer is midazolam. Midazolam is a benzodiazepine sedative used for anesthesia induction and sedation, but it is not a paralytic agent. Paralytic agents such as succinylcholine, vecuronium, and pancuronium are used to induce muscle relaxation during intubation. Attacruium is not a recognized drug and is likely a misspelling or typo.Rate this question:

The duration of action of succinylcholine (Anectine) is approx
- A.
1 to 2 minutes
- B.
2 to 3 minutes
- C.
3 to 5 minutes
- D.
4 to 6 minutes
- E.
10 to 15 minutes
Correct Answer
C. 3 to 5 minutesExplanation
Succinylcholine, also known as Anectine, has a duration of action of approximately 3 to 5 minutes. This means that its effects, such as muscle relaxation, will last for this period of time before wearing off. It is a short-acting medication commonly used during anesthesia to facilitate intubation or muscle relaxation during surgery. The relatively short duration of action allows for control and reversibility of its effects, making it a preferred choice in certain medical procedures.Rate this question:

In the intubation of children under 8 years old, it is recommended that the paramedic us
- A.
A cuffed endotracheal tube and a straight laryngoscope blade
- B.
An uncuffed endotracheal tube and a straight laryngoscope blade
- C.
A cuffed endotracheal tube and a curved laryngoscope blade
- D.
An ncuffed endotracheal tube and a curved laryngoscope blade
- E.
An uncuffed endotracheal tube and digital technique
Correct Answer
B. An uncuffed endotracheal tube and a straight laryngoscope bladeExplanation
In the intubation of children under 8 years old, it is recommended to use an uncuffed endotracheal tube and a straight laryngoscope blade. This is because the airways of children under 8 are smaller and more narrow compared to adults, making a cuffed endotracheal tube unnecessary. Using an uncuffed tube allows for better ventilation and reduces the risk of airway complications. Additionally, a straight laryngoscope blade is preferred as it provides better visualization of the vocal cords in children.Rate this question:

All of the following statements about the pediatric airway are true EXCEPT
- A.
The tongue is larger in relation to the oropharynx than in adults
- B.
The glottic opening is lower and more posterior than in adults
- C.
The vocal cords slant upward
- D.
The narrowest part is the cricoid cartilage
Correct Answer
B. The glottic opening is lower and more posterior than in adultsExplanation
The glottic opening refers to the opening between the vocal cords in the larynx. In adults, the glottic opening is indeed lower and more posterior. However, in pediatric patients, the glottic opening is higher and more anterior compared to adults. This is because the pediatric larynx is positioned higher in the neck and more anteriorly. Therefore, the correct answer is that the glottic opening is not lower and more posterior in pediatric patients.Rate this question:

In patients with clenched teeth or who are awake or combative, the preferred method of intubation is
- A.
Digital
- B.
Lighted stylet
- C.
Rapid-sequence with neuromuscular blockadge
- D.
Nasal
Correct Answer
C. Rapid-sequence with neuromuscular blockadgeExplanation
In patients with clenched teeth or who are awake or combative, the preferred method of intubation is rapid-sequence with neuromuscular blockade. This is because these patients may have a higher risk of airway obstruction or difficulty in maintaining a clear airway. Rapid-sequence intubation involves the administration of a sedative and a neuromuscular blocking agent to induce unconsciousness and muscle relaxation, allowing for easier intubation and ventilation. This method ensures a quicker and safer intubation process in patients with clenched teeth or who are awake or combative.Rate this question:

Blind nasotracheal intubation is contraindicated if the patient
- A.
Is apneic
- B.
Has sustained a mandibular injury
- C.
Is anorexic
- D.
Is severely obese
Correct Answer
A. Is apneicExplanation
Blind nasotracheal intubation is contraindicated if the patient is apneic because this procedure involves inserting a tube through the nose into the trachea to secure the airway. If the patient is already apneic, it means they are not breathing, and blind intubation may not be successful in establishing a patent airway. In such cases, alternative methods like bag-mask ventilation or a surgical airway may be necessary to ensure adequate oxygenation and ventilation.Rate this question:

The preferred point of entry when inserting a surgical airway is the
- A.
Hyoid membrane
- B.
Arytenoid folds
- C.
Cricothyroid membrane
- D.
Pyriform fossa
Correct Answer
C. Cricothyroid membraneExplanation
The cricothyroid membrane is the preferred point of entry when inserting a surgical airway. This membrane is located between the cricoid cartilage and the thyroid cartilage in the neck. It is a relatively thin and easily accessible area, making it ideal for emergency airway access. Inserting a surgical airway through the cricothyroid membrane allows for a quick and effective method of establishing an open airway in cases of severe respiratory distress or obstruction. The other options listed, such as the hyoid membrane, arytenoid folds, and pyriform fossa, are not typically used as entry points for a surgical airway.Rate this question:

The minimum acceptable vacuum level in suctioning units for the prehospital setting is
- A.
200 mmHG
- B.
300 mmHG
- C.
400 mmHG
- D.
500 mmHG
Correct Answer
B. 300 mmHGExplanation
The minimum acceptable vacuum level in suctioning units for the prehospital setting is 300 mmHG. This level of vacuum is required to effectively suction fluids and debris from the patient's airway. A vacuum level lower than 300 mmHG may not provide enough suction power to clear the airway effectively, potentially compromising the patient's breathing and oxygenation. Therefore, a vacuum level of 300 mmHG is the minimum requirement to ensure proper suctioning in the prehospital setting.Rate this question:

Both standard routes of gastric decompression put the patient at risk for all of the following EXCEPT
- A.
Misplacement into the brain
- B.
Vomiting
- C.
Misplacement into the trachea
- D.
Trauma or bleeding from poor technique
Correct Answer
A. Misplacement into the brainExplanation
The standard routes of gastric decompression involve inserting a tube either through the nose and into the stomach (nasogastric route) or directly through the abdominal wall into the stomach (gastrostomy route). Both routes carry risks such as vomiting, misplacement into the trachea, and trauma or bleeding from poor technique. However, misplacement into the brain is not a risk associated with these standard routes of gastric decompression.Rate this question:

An esophageal detector device (EDD) uses the anatomic principle that the
- A.
Trachea is rigid and will collapse under negative pressure
- B.
Trachea is rigid and will not collapse under negative pressure
- C.
Esophagus is rigid and will collapse under negative pressure
- D.
Esophagus is rigid and will not collapse under negative pressure
Correct Answer
B. Trachea is rigid and will not collapse under negative pressureExplanation
The correct answer is that the trachea is rigid and will not collapse under negative pressure. This means that when negative pressure is applied, the trachea will maintain its shape and not collapse. This principle is used in an esophageal detector device (EDD) to determine if the endotracheal tube is properly placed in the trachea or if it has accidentally been inserted into the esophagus. By applying negative pressure through the EDD, if the trachea is properly intubated, air will flow freely and no collapse will occur. However, if the tube is in the esophagus, the esophagus will collapse under negative pressure, indicating an incorrect placement.Rate this question:

The laryngoscope permits visualization of the vocal cords by lifting of the tongue and
- A.
Soft palate
- B.
Epiglottis
- C.
Hyoid bone
- D.
None of the above
Correct Answer
B. EpiglottisExplanation
The laryngoscope is a medical instrument used to visualize the vocal cords. It achieves this by lifting the tongue and soft palate, allowing a clear view of the structures in the throat. The epiglottis is a specific structure located in the throat that helps to prevent food and liquid from entering the windpipe during swallowing. Therefore, it is the correct answer as it is one of the structures that can be visualized using a laryngoscope.Rate this question:

The greatest advantage of a straight blade is
- A.
Greater displacement of the tongue
- B.
Indirect elevation of the epiglottis
- C.
Lessened chance of stimulating the gag reflex
- D.
Wider field of vision for intubation
Correct Answer
A. Greater displacement of the tongueExplanation
A straight blade provides a greater displacement of the tongue during intubation. This is advantageous because it allows for better visualization and access to the airway, making intubation easier and more successful. By displacing the tongue, the straight blade creates space in the oral cavity, reducing the risk of obstruction and improving the efficiency of the procedure. This is particularly important in cases where the tongue may be obstructing the airway or causing difficulties in intubation.Rate this question:
