Try each quiz question before looking at the correct answer. Use the explanations to review missed ideas, then come back to similar questions until the pattern feels familiar.

Question 1

1. A history of asthma and audible wheezing throughout all lung fields.
2. The patient is hypotensive with a blood pressure of 80/50 mmHg. (correct answer)
3. The patient reports a history of a previous myocardial infarction.
4. Pulse oximetry reading of 88% on a non-rebreather mask.

Explanation: CPAP increases intrathoracic pressure, which can decrease venous return to the heart (preload) and subsequently lower blood pressure. In a patient who is already hypotensive (systolic BP < 90-100 mmHg, per local protocol), applying CPAP can precipitate cardiovascular collapse. The other options are either indications for (wheezing, hypoxia) or not contraindications to (history of MI) CPAP use.

Question 2

1. Administer the nebulized albuterol treatment as planned.
2. Begin positive pressure ventilation with a bag-valve mask. (correct answer)
3. Apply a non-rebreather mask at 15 L/min and transport.
4. Establish IV access for potential medication administration.

Explanation: The patient's sudden decrease in respiratory rate, altered mental status (drowsiness), and disappearance of wheezing (a 'silent chest') are ominous signs of respiratory failure and impending arrest. She is no longer moving enough air to oxygenate herself or for a nebulizer to be effective. The immediate priority is to provide ventilatory support with a bag-valve mask.

Question 3

1. Administer a nebulized albuterol treatment for suspected bronchospasm.
2. Apply CPAP and monitor the patient's blood pressure and respiratory status. (correct answer)
3. Place the patient in a supine position to improve perfusion and apply a non-rebreather mask.
4. Assist ventilations with a bag-valve mask due to the patient's high respiratory rate.

Explanation: This patient's presentation is classic for cardiogenic pulmonary edema. The most appropriate initial AEMT intervention is CPAP, which increases intrathoracic pressure, helping to drive fluid out of the alveoli and reducing the work of breathing. Her blood pressure is adequate to tolerate CPAP. Albuterol is not indicated as the primary problem is fluid (crackles), not bronchospasm. A supine position would worsen her breathing. BVM is not yet needed as she is still moving air on her own.

Question 4

1. Hyperventilation; decrease the ventilation rate to 10-12 breaths per minute.
2. Hypotension post-ROSC; focus on blood pressure support and fluid administration. (correct answer)
3. Esophageal placement; remove the device and reinsert while ventilating with a BVM.
4. Bronchoconstriction; administer an in-line nebulized bronchodilator treatment.

Explanation: In a patient with return of spontaneous circulation (ROSC) after cardiac arrest, a low EtCO2 reading (target is 35-45 mmHg) often indicates poor pulmonary blood flow due to post-arrest hypotension. While hyperventilation can lower EtCO2, a value of 18 is more suggestive of a perfusion problem. The priority is to address the likely hypotension through measures like IV fluid administration, as per protocol. Esophageal placement would show near-zero EtCO2, and bronchoconstriction would affect the waveform shape.

Question 5

1. Apply CPAP to help re-expand the collapsed lung.
2. Place a bulky dressing over the right side of the chest.
3. Assist ventilations with a BVM to ensure adequate oxygenation.
4. Administer oxygen as tolerated and transport in a position of comfort. (correct answer)

Explanation: When you encounter a tall, thin young male with sudden chest pain and decreased lung sounds, you're likely dealing with a spontaneous pneumothorax. This population has a higher risk due to their body habitus and potential subpleural blebs that can rupture. The correct approach is D) Administer oxygen as tolerated and transport in a position of comfort. For a stable pneumothorax without tension signs (normal blood pressure, no tracheal deviation, no severe respiratory distress), supportive care is appropriate. The oxygen helps maintain adequate saturation while the patient assumes whatever position feels most comfortable for breathing. A) Apply CPAP is dangerous here. Positive pressure ventilation can worsen a pneumothorax by forcing more air into the pleural space, potentially converting a simple pneumothorax into a life-threatening tension pneumothorax. B) Place a bulky dressing treats an open pneumothorax (sucking chest wound), but this patient has a closed spontaneous pneumothorax. There's no external wound to seal, and this intervention wouldn't address the underlying problem. C) Assist ventilations with a BVM is premature and risky. The patient is breathing adequately (SpO2 93%, talking, anxious but alert). Like CPAP, positive pressure ventilation could worsen the pneumothorax. Key strategy: For pneumothorax questions, first determine if it's open vs. closed, then simple vs. tension. Avoid positive pressure unless the patient can't breathe adequately on their own. When in doubt with stable patients, supportive care and rapid transport are usually safest.

Question 6

1. Hypoventilation; you should increase the ventilation rate slightly. (correct answer)
2. Hyperventilation; you should decrease the ventilation rate slightly.
3. Poor perfusion; you should administer an IV fluid bolus.
4. Adequate ventilation; you should continue at the current rate and volume.

Explanation: A normal EtCO2 range is 35-45 mmHg. A reading of 55 mmHg indicates hypercarbia, which means CO2 is being retained. In a patient being ventilated, this is due to hypoventilation (ventilating too slowly or with insufficient volume). The correct action is to slightly increase the rate or volume of ventilations to blow off more CO2 and bring the EtCO2 down into the normal range.

Question 7

1. Administering a nebulized albuterol treatment to relieve wheezing.
2. Initiating chest compressions due to lethargy.
3. Establishing IO access for fluid administration.
4. Suctioning the nares and providing supplemental oxygen. (correct answer)

Explanation: When you encounter a pediatric patient with respiratory distress, your priority is always to address the airway and oxygenation first. This infant shows classic signs of significant respiratory compromise: rapid shallow breathing, nasal flaring, wheezing, lethargy, and hypoxemia (SpO2 90%). The presentation suggests bronchiolitis, common in infants with recent viral illnesses. The correct intervention is D) Suctioning the nares and providing supplemental oxygen because it addresses the two most immediate threats. Infants are obligate nose breathers, so nasal congestion from the "cold" significantly impairs their breathing. Clearing the nasal passages restores airway patency, while supplemental oxygen directly addresses the hypoxemia and reduces respiratory work. A) Nebulized albuterol is incorrect because bronchiolitis in infants under 12 months typically doesn't respond well to bronchodilators due to underdeveloped smooth muscle in their airways. The wheezing is often from inflammation and mucus, not bronchospasm. B) Chest compressions is wrong because lethargy here indicates hypoxemia, not cardiac arrest. The infant likely has a pulse and adequate circulation—they just need better oxygenation. C) IO access for fluids is premature. While the infant may eventually need IV access, the immediate priority is airway and breathing support. There's no indication of shock or dehydration requiring urgent fluid resuscitation. NREMT Strategy: Remember your ABCs—Airway, Breathing, Circulation. In pediatric respiratory cases, always address airway patency and oxygenation before moving to other interventions, even if they seem clinically appropriate.

Question 8

1. Insert a supraglottic airway, then administer naloxone.
2. Administer naloxone, then begin BVM ventilations if he does not improve.
3. Begin BVM ventilations, insert an airway adjunct, and then establish IV access. (correct answer)
4. Establish IV access, administer naloxone, then support ventilations.

Explanation: The patient is in respiratory failure, likely due to an opioid overdose. The immediate life threat is inadequate ventilation. The correct sequence follows the ABCs: immediately begin positive pressure ventilation with a BVM, insert an oropharyngeal or nasopharyngeal airway to help maintain patency, and then address circulation with IV access. While naloxone is important, restoring ventilation is the first and most critical action.

Question 9

1. Hyperventilation secondary to anxiety.
2. Increased dead space ventilation from a pulmonary embolism.
3. Airflow obstruction in the lower airways. (correct answer)
4. Poor capnography sensor placement or an air leak.

Explanation: The 'shark-fin' or sloped shape of the capnography waveform is a classic sign of bronchoconstriction or lower airway obstruction. This occurs because air is 'trapped' in the alveoli and exhaled slowly and unevenly, preventing a sharp, clear expiratory plateau. This is commonly seen in conditions like asthma and COPD (including chronic bronchitis).

Question 10

1. Applying a bulky dressing taped on three sides over the segment.
2. Administering high-flow oxygen via a non-rebreather mask.
3. Providing positive pressure ventilation with a BVM. (correct answer)
4. Placing the patient on their injured side to stabilize the fracture.

Explanation: The patient has a flail chest with paradoxical motion, which severely impairs the ability to generate negative intrathoracic pressure for effective ventilation. The most critical intervention is to provide positive pressure ventilation (PPV) with a BVM. PPV acts as an 'internal splint,' stabilizing the flail segment and ensuring adequate tidal volume. While high-flow oxygen is necessary, it does not correct the underlying mechanical problem of ventilation.

Question 11

1. Pulmonary edema; increase the CPAP pressure to 10 cmH2O.
2. Mucous plugging; suction the patient and continue CPAP.
3. Pneumothorax; remove CPAP and assist ventilations with a BVM. (correct answer)
4. Myocardial infarction; acquire a 12-lead ECG and continue CPAP.

Explanation: The acute deterioration, hypotension, tachycardia, and newly diminished lung sounds on one side in a patient with emphysema on positive pressure (CPAP) are highly suggestive of a barotrauma-induced pneumothorax. Continuing CPAP would worsen the pneumothorax, potentially causing a tension pneumothorax. The correct action is to remove the CPAP, provide oxygen, and assist ventilations gently with a BVM as needed, followed by rapid transport.

Question 12

1. Spontaneous pneumothorax; assist ventilations with a BVM.
2. Myocardial infarction; acquire a 12-lead ECG immediately.
3. Pulmonary embolism; administer high-concentration oxygen. (correct answer)
4. Anxiety attack; instruct the patient to breathe into a paper bag.

Explanation: The sudden onset of dyspnea and pleuritic chest pain, clear lung sounds, tachycardia, and hypoxia, combined with a risk factor (long flight), is a classic presentation for a pulmonary embolism. Prehospital management is supportive and focuses on administering high-concentration oxygen to manage hypoxia and initiating rapid transport. BVM is not indicated as she is breathing spontaneously, and while an ECG is reasonable, oxygen is the priority for her respiratory compromise.

Question 13

1. Assist ventilations with a bag-valve mask at a rate of 20/min.
2. Administer a nebulized bronchodilator and apply continuous positive airway pressure (CPAP). (correct answer)
3. Replace his nasal cannula with a simple face mask at 6 L/min to avoid over-oxygenation.
4. Establish IV access and administer a 500 mL normal saline fluid bolus to thin secretions.

Explanation: This patient presents with a severe COPD exacerbation. He is in respiratory distress but not failure, as he is still maintaining his own respiratory effort. The combination of a nebulized bronchodilator to address the bronchospasm (indicated by wheezing and the shark-fin capnogram) and CPAP to decrease the work of breathing and improve gas exchange is the most appropriate and comprehensive AEMT-level treatment.

Question 14

1. Tachypnea, tachycardia, and use of accessory muscles.
2. Wheezing, a prolonged expiratory phase, and tripoding.
3. Altered mental status, bradypnea, and poor respiratory effort. (correct answer)
4. SpO2 of 92%, anxiety, and ability to speak in full sentences.

Explanation: Respiratory distress is a state of increased work of breathing while still maintaining adequate gas exchange. Respiratory failure occurs when the body's compensatory mechanisms fail, leading to inadequate oxygenation and/or ventilation. The hallmark signs of this transition include altered mental status (from hypoxia/hypercarbia), a slowing respiratory rate (bradypnea) due to fatigue, and poor tidal volume/effort.

Question 15

1. Pulmonary embolism; begin BVM ventilations immediately.
2. COPD exacerbation; administer a nebulized bronchodilator.
3. Pneumonia; provide oxygen via a non-rebreather mask. (correct answer)
4. Congestive heart failure; apply CPAP at 5 cmH2O.

Explanation: The combination of fever, confusion, localized rhonchi, and hypoxia in an elderly patient is highly suggestive of pneumonia. The immediate priority is to correct the hypoxia. A non-rebreather mask at 15 L/min is the appropriate initial intervention to increase her oxygen saturation. BVM is not yet indicated as she has a respiratory rate of 26. While she has rhonchi, widespread bronchospasm is not suggested, and CHF is less likely without crackles/rales.

Question 16

1. Administer a second dose of epinephrine per protocol. (correct answer)
2. Apply CPAP to help force the upper airway open.
3. Administer a nebulized albuterol treatment.
4. Establish an IV and rapidly administer a fluid bolus.

Explanation: This patient is showing signs of a severe anaphylactic reaction that is not fully resolved after one dose of epinephrine (persistent stridor, sensation of airway closing). The priority is to reverse the systemic effects of the reaction. Per national guidelines, if signs and symptoms persist or worsen after the first dose, a second dose of epinephrine should be administered. CPAP is contraindicated with upper airway obstruction, and albuterol does not treat the laryngeal edema causing the stridor.

Question 17

1. Administer a nebulized albuterol treatment. (correct answer)
2. Establish an IV and administer a 1L fluid bolus.
3. Immediately insert a supraglottic airway.
4. Irrigate the patient's eyes and face with sterile saline.

Explanation: Toxic inhalation can cause severe irritation and inflammation of the airways, leading to bronchospasm. The presence of wheezing indicates that this is occurring. After ensuring airway patency and providing oxygen, administering a nebulized bronchodilator like albuterol is the next priority to treat the bronchoconstriction and improve air movement. An SGA is not yet indicated, and while an IV and decontamination are important, they are secondary to treating the respiratory distress.

Question 18

1. An EtCO2 reading of 65 mmHg. (correct answer)
2. The presence of bibasilar crackles on auscultation.
3. A heart rate of 110 beats per minute.
4. Patient complaint of generalized weakness.

Explanation: In neuromuscular disease, respiratory failure often results from ventilatory muscle fatigue, leading to inadequate tidal volume and CO2 retention (hypercarbia). An elevated EtCO2 of 65 mmHg is a direct measurement of severe ventilatory failure. This indicates that despite her efforts (tachypnea), she cannot effectively eliminate CO2 and requires assistance with ventilation, such as with a BVM or CPAP, to prevent respiratory arrest.

Question 19

1. Separate the child from the parent to perform a detailed physical exam.
2. Administer blow-by humidified oxygen and transport in a position of comfort. (correct answer)
3. Apply a pediatric non-rebreather mask at 15 L/min to maximize FiO2.
4. Prepare to assist ventilations with a BVM due to the presence of stridor.

Explanation: This presentation is classic for laryngotracheobronchitis (croup). Management focuses on minimizing agitation, which can worsen the upper airway obstruction. Allowing the child to remain with the parent in a position of comfort is key. Providing humidified oxygen via blow-by is the least invasive way to offer support. Aggressive interventions like forced masks or separating the child from the parent can increase distress and are not indicated given the stable oxygen saturation.

Question 20

1. Increase the force of ventilations to overcome the resistance.
2. Request a paramedic intercept for endotracheal intubation.
3. Switch to a nasopharyngeal airway.
4. Insert a supraglottic airway device. (correct answer)

Explanation: When you encounter airway management scenarios on the NREMT, think systematically through your options based on what's already been attempted and failed. This question tests your understanding of the airway management hierarchy and when to escalate interventions. The correct answer is D because a supraglottic airway device addresses both problems mentioned: poor mask seal and inadequate ventilation. After basic positioning and an oral airway have failed, a supraglottic device like an i-gel or King LT is the next logical step in your scope of practice. These devices bypass the need for a mask seal entirely and provide a more secure airway than bag-valve mask ventilation. Option A is dangerous because increasing ventilation force can cause gastric insufflation, barotrauma, or pneumothorax. The resistance isn't the primary problem—it's the poor seal and airway positioning that basic maneuvers couldn't correct. Option B delays definitive care unnecessarily. While paramedic intercept might eventually be needed, you should exhaust your available interventions first. Supraglottic airways are within AEMT scope and can be inserted quickly. Option C won't solve the fundamental problem. A nasopharyngeal airway might help with airway positioning, but you'll still have the same mask seal issues that prevented adequate ventilation in the first place. Remember this progression for NREMT airway questions: basic positioning and adjuncts first, then supraglottic devices, then consider advanced interventions. Don't skip steps in your scope of practice when a solution is readily available.
