respiratory emergencies 2

You are assessing a 52-year-old male with respiratory distress. The MOST ominous sign(s) of severe hypoxemia and imminent cardiac arrest is/are:

a marked decrease in the heart rate.

Which of the following conditions would be LEAST likely to result in cerebral hypoxia?

Methamphetamine overdose

Which of the following physiologic processes occurs during pulmonary respiration?

Carbon dioxide diffuses into the alveoli.

You are dispatched to the home of a 64-year-old male patient with lung cancer. The patient complains of acute dyspnea; however, as long as he is sitting upright, his breathing is easier. He denies fever and his breath sounds are decreased over the base of the left lung. What is the MOST likely cause of this patient's symptoms?

Collection of fluid outside of the lung

You are dispatched to a residence for a 69-year-old female with "breathing problems." When you arrive, the patient's husband directs you to his wife, who is sitting on the couch in obvious respiratory distress. She is semiconscious and has labored, shallow respirations. You auscultate her lungs and hear diffuse rhonchi in all lung fields. Which of the following interventions would be of LEAST benefit to her?

IV therapy with up to a 500 mL normal saline bolus

Which of the following physiologic processes does NOT occur in patients with COPD

Increased surfactant production

Which of the following is generally NOT indicated when treating a patient with a tension pneumothorax?

Medication therapy

Which of the following is the MOST accurate clinical definition of chronic bronchitis?

Productive cough for 3 months per year for 3 consecutive years

Which of the following clinical findings is MOST consistent with inadequate breathing?

Respirations of 16 breaths/min and reduced tidal volume

Which of the following statements MOST accurately describes asthma?

Reversible airway disease caused by an exaggerated immune response

When assessing a patient with difficulty breathing, which of the following findings would lead you to suspect congestive heart failure as the underlying cause?

The onset of the difficulty breathing was acute and the patient takes prescribed diuretics.

When treating a patient who complains of dyspnea, it is important for the AEMT to:

be prepared to treat the patient's anxiety as well.

You are assessing a young male with an acute onset of tachypnea. He is conscious and alert with shallow respirations of 40 breaths/min, and complains of numbness and tingling to his face and hands. The patient's girlfriend tells you that he has been very worried about his mother, who was recently diagnosed with cancer. Appropriate treatment for this patient includes:

coached breathing and oxygen as needed.

The movement and utilization of oxygen in the body is dependent on all of the following, EXCEPT:

effective alveolar-capillary osmosis.

When assisting a patient with his or her prescribed inhaler, it is important to:

have the patient exhale deeply prior to inhaling the medication

When assessing the severity of nocturnal dyspnea in a patient with a chronic respiratory disease, you should determine:

how many pillows he or she sleeps with at night.

You are treating a 2-year-old boy who is experiencing respiratory distress. During your assessment, you note that the child has mild inspiratory stridor, a barking cough, and a low-grade fever. The child is otherwise conscious, is acting appropriate for his age, and has strong radial pulses. Treatment should include:

humidified oxygen.

You are dispatched for an elderly male with dyspnea. When you arrive, you find the patient sitting in a chair. He is semiconscious and unable to effectively communicate with you. As you perform a primary assessment, your partner applies 100% oxygen and a pulse oximeter, which reads 85%. The MOST reliable indicator of cerebral hypoxia in this patient is his:

mental status alteration.
