2024 EMT JBL Respiratory New Full Questions and Answers ( Included ) 100% Correct

• A 50-year-old woman presents with acute shortness of breath. Her skin is pale and she is

anxious. You should:

• administer high-flow oxygen and assess the adequacy of her breathing.
• place her supine and ventilate her with a bag-valve-mask device.
• deliver humidified oxygen and administer an inhaled bronchodilator.
• give supplemental oxygen only if her oxygen saturation is less than 90%.

Answer: A

• Which of the following situations would MOST likely impair oxygenation, despite the fact

that the patient is inhaling and exhaling?

• Limb amputation
• Intracranial hemorrhage
• Acute myocardial infarction
• Entrapment in a mine

Answer: D

• An unresponsive patient has an end-tidal carbon dioxide level of 70 mm Hg. From this, you

should conclude that the patient is:

• hypercarbic and breathing adequately.
• hypocarbic and breathing adequately.
• hypercarbic and breathing inadequately.
• hypocarbic and breathing inadequately.

Answer: C

• To ensure you deliver the highest concentration of oxygen with a nonrebreathing mask, you

should:

• set the flow rate to at least 10 to 12 L/min.
• securely fasten the mask to the patient's face.
• make sure that the reservoir bag is preinflated.
• cover the one-way valves on the oxygen mask.

Answer: C

• A 35-year-old male complains of shortness of breath. He is conscious and alert and is able

to speak in complete sentences. Assessment reveals diffuse wheezing to auscultation, a respiratory rate of 22 breaths/min, a heart rate of 110 beats/min, and an oxygen saturation of 92%. Which of the following interventions would be of MOST benefit to this patient?

• A beta antagonist
• Assisted ventilation
• Supplemental oxygen 1 / 3

• Inhaled bronchodilator

Answer: D

• Occasional, irregular breaths that may be observed in a cardiac arrest patient are called:
• Biot respirations.
• agonal gasps.
• ataxic respirations.
• Cheyne-Stokes respirations.

Answer: B

• You are assessing a 66-year-old man who has emphysema and complains of worsened

shortness of breath. He is confused, has a heart rate of 120 beats/min, and has an oxygen saturation of 83%. Which of the following assessment findings should concern you the MOST?

• Confusion
• Tachycardia
• Low oxygen saturation
• Worsened shortness of breath

Answer: A

• An unresponsive apneic patient's chest fails to rise after two ventilation attempts. You

should:

• immediately proceed to chest compressions.
• suction the airway and reattempt ventilations.
• attempt to ventilate again using more volume.
• reposition the head and reattempt to ventilate.

Answer: A

• When ventilating an apneic patient with a bag-valve-mask device, each breath should be

delivered over:

• 1 second.
• 2 seconds.
• 3 seconds.
• 4 seconds.

Answer: A

• To obtain the MOST reliable assessment of a patient's tidal volume, you should:
• assess for retractions.
• listen for airway noises.
• count the respiratory rate.
• look at the rise of the chest.

Answer: D 2 / 3

• An unresponsive 60-year-old male is apneic and has a weak, rapid pulse. His oxygen

saturation reads 79%. You should:

• deliver one breath over 1 second every 5 to 6 seconds.
• use a pocket face mask to deliver 12 to 20 breaths/min.
• hyperventilate him until his oxygen saturation improves.
• deliver a maximum of 10 breaths/min, each over 1 second.

Answer: A

• A patient who is breathing with reduced tidal volume would MOST likely have:
• warm, moist skin.
• shallow respirations.
• a prolonged inhalation phase.
• a respiratory rate of 14 breaths/min.

Answer: B

• A 40-year-old man is conscious, but has an increased rate of breathing. You should:
• apply 100% oxygen via nonrebreathing mask.
• immediately insert a nasopharyngeal airway.
• assess the regularity and quality of breathing.
• ventilate him with a bag-mask device.

Answer: C

• In which position would you expect a patient with severe dyspnea to be found?
• Prone
• Supine
• Fowler's
• Lateral recumbent

Answer: C

15. A patient's skin will MOST likely become cyanotic if he or she has:

• a decrease in the amount of carbon dioxide.
• an increase in the amount of arterial oxygen.
• a decrease in the amount of arterial oxygen.
• an overall increase in circulating red blood cells.

Answer: C

16. In an otherwise heathy individual, breathing is stimulated when:

• arterial carbon dioxide levels increase.
• arterial blood pressure decreases.
• arterial oxygen levels decrease.
• pH of the cerebrospinal fluid increases.
