Question 1

1. Open the airway using head-tilt, chin-lift maneuver (correct answer)
2. Check for visible obstructions in the mouth
3. Insert an oropharyngeal airway immediately
4. Begin bag-valve-mask ventilation

Explanation: The correct answer is A. The first step in airway assessment of an unresponsive patient is to open the airway using head-tilt, chin-lift (or jaw-thrust if spinal injury suspected) to allow visualization and access. B is incorrect because you must first open the airway to properly see and access potential obstructions. C is incorrect because airway adjuncts are inserted after opening and clearing the airway. D is incorrect because ventilation comes after ensuring the airway is open and clear.

Question 2

1. When the patient is conscious and cooperative
2. When you suspect a cervical spine injury (correct answer)
3. When the patient has dentures in place
4. When performing rescue breathing with oxygen

Explanation: The correct answer is B. The jaw-thrust maneuver is used when cervical spine injury is suspected because it opens the airway without extending the neck, minimizing spinal movement. A is incorrect because conscious patients typically maintain their own airway and positioning preference. C is incorrect because dentures don't determine airway opening technique choice. D is incorrect because the type of ventilation doesn't dictate which airway opening method to use.

Question 3

1. Patient has an intact gag reflex present
2. Patient is semi-conscious with altered mental status
3. Patient has suspected basilar skull fracture (correct answer)
4. Patient requires assisted ventilation with BVM

Explanation: The correct answer is C. Basilar skull fractures can create a pathway from the nasal cavity to the brain, making NPA insertion dangerous as it could potentially penetrate brain tissue. A is incorrect because intact gag reflex is actually an indication for NPA over OPA. B is incorrect because altered mental status patients often benefit from NPAs. D is incorrect because NPAs can be used with bag-valve-mask ventilation.

Question 4

1. 5 seconds to prevent hypoxia development
2. 10 seconds to prevent hypoxia development (correct answer)
3. 15 seconds to ensure complete clearance
4. 20 seconds to ensure complete clearance

Explanation: The correct answer is B. Suctioning should be limited to 10 seconds per attempt to prevent hypoxia, as suctioning removes oxygen along with secretions from the airway. A is incorrect because 5 seconds may be insufficient to clear significant obstructions. C is incorrect because 15 seconds is too long and increases hypoxia risk. D is incorrect because 20 seconds would cause dangerous oxygen depletion and potential patient harm.

Question 5

1. Patient becomes unconscious and stops fighting the obstruction
2. High-pitched wheezing sounds become more pronounced
3. Patient can speak clearly and cough forcefully (correct answer)
4. Skin color changes from normal to slightly pale

Explanation: The correct answer is C. The ability to speak clearly and cough forcefully indicates that the airway is clear and air is moving effectively through the vocal cords. A is incorrect because unconsciousness indicates worsening condition and potential complete obstruction. B is incorrect because increased wheezing suggests ongoing partial obstruction. D is incorrect because pale skin color indicates poor oxygenation and ongoing airway compromise.

Question 6

1. Patient begins to breathe more rapidly than before
2. Patient starts to gag or shows signs of vomiting (correct answer)
3. Patient's oxygen saturation begins to improve slowly
4. Patient requires assisted ventilation with bag-valve-mask

Explanation: The correct answer is B. Gagging or signs of vomiting indicate the return of protective reflexes, making the OPA inappropriate and potentially dangerous as it could stimulate more vomiting. A is incorrect because increased respiratory rate doesn't necessarily indicate OPA problems. C is incorrect because improving oxygen saturation suggests the OPA is working effectively. D is incorrect because OPAs can be used effectively with bag-valve-mask ventilation.

Question 7

1. Replace the OPA with a nasopharyngeal airway for better tolerance
2. Begin assisted ventilation with a bag-valve-mask device (correct answer)
3. Position the patient in recovery position to prevent aspiration
4. Administer high-flow oxygen via non-rebreather mask only

Explanation: The correct answer is B. Shallow, inadequate breathing requires assisted ventilation with a bag-valve-mask to ensure adequate oxygenation and ventilation. A is incorrect because the OPA is appropriate for this unconscious patient and doesn't need replacement. C is incorrect because repositioning won't address the inadequate breathing that requires immediate intervention. D is incorrect because passive oxygen delivery won't correct inadequate ventilation; active assistance is needed.

Question 8

1. Patient has rapid, shallow breathing patterns
2. Patient demonstrates audible gurgling or wet sounds (correct answer)
3. Patient shows signs of cyanosis around the lips
4. Patient has decreased level of consciousness present

Explanation: The correct answer is B. Gurgling or wet sounds indicate the presence of fluids (blood, vomit, secretions) in the airway that require immediate suctioning for removal. A is incorrect because rapid, shallow breathing alone doesn't necessarily indicate need for suctioning. C is incorrect because cyanosis indicates poor oxygenation but not necessarily fluid in the airway. D is incorrect because decreased consciousness alone doesn't indicate suctioning needs unless accompanied by fluid sounds.

Question 9

1. Patient tolerates the device without any gag reflex response
2. Improved air movement with easier bag-valve-mask ventilation (correct answer)
3. Device sits securely without risk of displacement during transport
4. Patient's oxygen saturation increases to normal levels immediately

Explanation: The correct answer is B. Improved air movement and easier ventilation directly indicate that the airway adjunct is maintaining airway patency and functioning as intended. A is incorrect because lack of gag reflex indicates appropriate unconsciousness level but not necessarily proper positioning. C is incorrect because security of placement doesn't indicate functional effectiveness. D is incorrect because oxygen saturation improvement depends on multiple factors beyond just airway adjunct positioning.

Question 10

1. Jaw-thrust maneuver while maintaining neutral head alignment
2. Head-tilt, chin-lift maneuver with gentle extension (correct answer)
3. Triple airway maneuver with head extension and jaw displacement
4. Modified jaw-thrust with simultaneous head-tilt positioning

Explanation: The correct answer is B. When cervical spine injury is not suspected, the head-tilt, chin-lift maneuver is the preferred method as it effectively opens the airway by lifting the tongue off the posterior pharynx. A is incorrect because jaw-thrust is reserved for when spinal injury IS suspected. C is incorrect because 'triple airway maneuver' is not a standard EMT technique. D is incorrect because combining jaw-thrust with head-tilt defeats the spinal protection purpose of jaw-thrust.

Question 11

1. Rigid catheters provide stronger suction power than flexible catheters
2. Flexible catheters are designed for deeper airway access beyond pharynx
3. Rigid catheters are designed for visible secretions in mouth and pharynx (correct answer)
4. Flexible catheters cause less patient discomfort during suctioning procedures

Explanation: The correct answer is C. Rigid catheters (Yankauer) are specifically designed for suctioning visible secretions in the mouth and pharynx where direct visualization is possible. B is incorrect because while flexible catheters can access deeper areas, this describes function rather than the primary design difference. A is incorrect because suction power comes from the suction device, not the catheter type. D is incorrect because patient comfort is not the primary distinguishing characteristic between catheter types.

Question 12

1. Insert deeply and apply suction while advancing the catheter
2. Insert only as deep as you can visualize (correct answer)
3. Insert to maximum depth and withdraw while suctioning
4. Insert past the vocal cords for effective clearance

Explanation: The correct answer is B. Rigid suction catheters should only be inserted as deep as you can see to avoid trauma to unseen structures and prevent pushing material deeper into the airway. A is incorrect because applying suction while advancing can cause tissue damage and push debris deeper. C is incorrect because inserting to maximum depth risks trauma to delicate airway structures. D is incorrect because rigid catheters should never be inserted past the vocal cords.

Question 13

1. Position the patient in a supine position for assessment
2. Suction the airway to remove blood and secretions (correct answer)
3. Apply high-flow oxygen via non-rebreather mask
4. Insert a nasopharyngeal airway to maintain patency

Explanation: The correct answer is B. Gurgling sounds indicate the presence of blood, vomit, or secretions in the airway that must be immediately suctioned to prevent aspiration and maintain airway patency. A is incorrect because positioning comes after clearing the airway, and supine may worsen the situation. C is incorrect because oxygen delivery is ineffective if the airway is obstructed with secretions. D is incorrect because inserting an airway adjunct without first clearing secretions could push material deeper.

Question 14

1. Easy compression of the bag with visible chest rise
2. Difficulty compressing the bag with minimal chest movement (correct answer)
3. Slight resistance during bag compression with adequate chest rise
4. Normal bag compression with bilateral breath sounds present

Explanation: The correct answer is B. Difficulty compressing the bag with minimal chest movement indicates airway obstruction preventing effective ventilation delivery to the lungs. A is incorrect because easy compression with visible chest rise indicates good airway patency and effective ventilation. C is incorrect because slight resistance is normal and adequate chest rise shows effective ventilation. D is incorrect because normal compression with bilateral sounds indicates proper airway management and ventilation.

Question 15

1. Head-tilt chin-lift, suction blood, insert OPA, provide oxygen
2. Suction blood, jaw-thrust maneuver, insert NPA, assess breathing (correct answer)
3. Position patient on side, suction blood, open airway, insert OPA
4. Jaw-thrust maneuver, suction blood immediately, insert OPA, ventilate

Explanation: The correct answer is B. With suspected spinal injury, the sequence is: suction visible blood first, use jaw-thrust to open airway (spinal precautions), insert NPA (better tolerated and doesn't require mouth opening), then assess breathing. A is incorrect because head-tilt chin-lift is contraindicated with spinal injury. C is incorrect because positioning on side compromises spinal precautions. D is incorrect because airway should be cleared before opening, and OPA requires mouth opening which is difficult with jaw-thrust.

Question 16

1. The patient tolerates insertion without gagging reflexes
2. The flange sits flush against the patient's lips
3. The airway pushes the epiglottis over the glottic opening (correct answer)
4. The device requires rotation during insertion technique

Explanation: The correct answer is C. An OPA that is too large can push the epiglottis down over the glottic opening, actually causing airway obstruction rather than maintaining patency. A is incorrect because lack of gag reflex indicates appropriate unconsciousness level for OPA use. B is incorrect because proper flange positioning indicates correct sizing and placement. D is incorrect because rotation is a normal part of OPA insertion technique, not a sizing indicator.

Question 17

1. Snoring respirations during inspiration and expiration (correct answer)
2. Complete silence with no audible breath sounds
3. Normal, quiet breathing with regular rhythm
4. Occasional coughing with clear speech patterns

Explanation: The correct answer is A. Snoring respirations indicate partial airway obstruction, typically from the tongue or soft tissues partially blocking the airway. B is incorrect because complete silence indicates complete obstruction or absent breathing. C is incorrect because normal quiet breathing indicates a patent airway without obstruction. D is incorrect because unconscious patients cannot cough purposefully or speak clearly.

Question 18

1. To provide supplemental oxygen delivery to conscious patients
2. To maintain airway patency in unresponsive patients (correct answer)
3. To prevent vomiting during transport procedures
4. To assist with bag-valve-mask seal formation

Explanation: The correct answer is B. An oropharyngeal airway is designed to maintain airway patency in unresponsive patients by preventing the tongue from falling back and obstructing the airway. A is incorrect because OPAs don't deliver oxygen; they maintain airway structure. C is incorrect because OPAs don't prevent vomiting and may actually stimulate the gag reflex. D is incorrect because while an OPA may help with ventilation, its primary purpose is maintaining airway patency, not mask seal.

Question 19

1. From the corner of mouth to the earlobe
2. From the tip of the nose to the earlobe (correct answer)
3. From the nostril opening to the tragus of ear
4. From the bridge of nose to the angle of jaw

Explanation: The correct answer is B. The proper size NPA is measured from the tip of the nose to the earlobe, ensuring adequate length to reach the posterior pharynx without being too long. A is incorrect because mouth-to-earlobe measurement is used for oropharyngeal airways. C is incorrect because nostril-to-tragus doesn't provide the proper anatomical length reference. D is incorrect because this measurement doesn't correspond to the nasopharyngeal pathway anatomy.

Question 20

1. Complete airway obstruction requiring immediate back blows
2. Partial airway obstruction with some air movement (correct answer)
3. Normal breathing with anxiety-induced voice changes
4. Laryngeal spasm requiring aggressive airway maneuvers

Explanation: The correct answer is B. High-pitched sounds (stridor) indicate partial airway obstruction where some air is still moving through a narrowed airway passage. A is incorrect because complete obstruction produces no sounds as no air moves. C is incorrect because the inability to speak and throat-pointing indicate true obstruction, not anxiety. D is incorrect because laryngeal spasm would produce different sounds and presentation patterns.
