With proper insertion, the tip should rest in the laryngopharynx so it can fully support the tongue. The administration of a beta2-specific drug to a patient with respiratory distress is done to effect a change to what portion of the respiratory tree? a. Alveoli b. Vocal cords c. Bronchioles d. Mainstem bronchi - ANSWER Answer: C A beta2-specific drug will relax smooth muscle, the kind that wraps the bronchioles of the lungs. This relaxation will allow better airflow to the alveoli for gas exchange. Which of the following statements from the patient would BEST indicate severe difficulty in breathing? a. "I...can't...b-breathe." b. "I feel like I'm breathing through a straw." c. "I am struggling to catch my breath... real bad." d. "I can't breathe regular 'cause my chest is hurting." - ANSWER Answer: A A key ability of the EMT is to recognize the difference between adequate and inadequate breathing. A patient who can speak in full sentences (multiple words in one breath) is typically breathing adequately. A patient who cannot speak in full sentences (usually less than two to three words per breath) is not breathing adequately and will need oxygen (and probably PPV support).
