Look at the rise of the chest - (ANSWER)To obtain the MOST reliable assessment of a patient's tidal
volume, you should:
It lubricates the alveolar walls and allow them to expand and recoil. - (ANSWER)What is the function of
pulmonary surfactant?
Keeps the tongue off of the posterior pharynx. - (ANSWER)A properly placed oropharyngeal airway:
Begin CPR, starting with chest compressions - (ANSWER)You are performing abdominal thrusts on a 19-
year-old male with a severe airway obstruction when he becomes unresponsive. After lowering him to
the ground and placing him in a supine position, you should:
Severe peripheral vasoconstriction. - (ANSWER)An inaccurate pulse oximetry reading may be caused by:
Position the patient onto his side - (ANSWER)While ventilating an unresponsive man with a bag-mask
device, you hear gurgling in his upper airway. you should:
The respiratory rate and depth increase. - (ANSWER)If the level of carbon dioxide in the arterial blood
increases:
Hypercarbia and acidosis - (ANSWER)A 30-year-old woman overdosed on pain pills and is unresponsive.
she is breathing at a rate of 6 breaths/min with shallow depth. left untreated, she will develop:
movement of air into and out of the lungs - (ANSWER)Ventilation is defined as the:
A barrel-shaped chest - (ANSWER)Which of the following clinical finding is MOST consistent with a
chronic respiratory disease?

inhaled bronchodilator - (ANSWER)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?
administer high-flow oxygen and assess the adequacy of her breathing. - (ANSWER)A 50-year-old
woman presents with acute shortness of breath. her skin is pale and she is anxious. you should:
is typically not cyanotic - (ANSWER)A patient with a mild foreign body airway obstruction:
Ventilation - (ANSWER)A patient overdosed on heroin and is unresponsive. he is cyanotic: he has slow,
shallow breathing: and his oxygen saturation is 80%. The primary cause of this patient's condition is
inadequate:
Deep, rapid breathing - (ANSWER)All of the following would cause an increased level of carbon dioxide
in the arterial blood. EXCEPT:
oxygen supports combustion and should not be used where sparks are easily gererated. -
(ANSWER)When attaching an oxygen regulator to a D cylinder and preparing it for use, you should recall
that:
squeeze the bag slowly and release when you observe chest rise. - (ANSWER)In order to avoid forcing air
into the stomach during bag-mask ventilation, you should
Diffuse bronchoconstriction. - (ANSWER)Assessment of a 40-year-old patient reveals respiratory
distress, tachycardia, audible expiratory wheezing, and an oxygen saturation of 88%. The EMT should
suspect:
increase in residual volume - (ANSWER)Assessment of an older man with respiratory distress reveals
that his chest has a barrel-shaped appearance and he is exhaling through pursed lips. what is the
pathophysiology of these findings?
