A 56-year-old man has labored, shallow breathing at a rate of 28 breaths/min. He is
responsive to pain only. You should:
A) suction his oropharynx and insert an oropharyngeal airway.
B) ventilate him with a bag-valve-mask device at a rate of 30 breaths/min.
C) place him on his side and administer oxygen via nonrebreathing mask.
D) insert a nasopharyngeal airway and begin assisting his ventilations. - 🧠
ANSWER ✔✔D) insert a nasopharyngeal airway and begin assisting his
ventilations.
This patient in this scenario is not breathing adequately. He is responsive to pain
only, and his respirations are rapid, labored, and shallow. You should insert a

,nasopharyngeal airway, which is better tolerated in patients who are semiconscious
and have a gag reflex, and assist his ventilations with a bag-valve-mask
device. When assisting a patient's breathing, you should squeeze the bag-valve-
mask device to ensure that he or she receives 10 to 12 adequate breaths per
minute. Do not hyperventilate the patient, as this increases the risks of vomiting
and aspiration. Hyperventilation also increases intra thoracic pressure,
which may impair venous return to the heart (preload} and cause a decrease in
cardiac output. Oxygen via nonrebreathing mask is appropriate for patients
who are breathing adequately, but are suspected of being hypoxic. The recovery
position (patient is placed on his or her side) is appropriate for unresponsive,
uninjured patients with adequate breathing.
A patient overdosed on several drugs and is unresponsive with shallow breathing
and facial cyanosis. As you continue your assessment, the
patient suddenly vomits. You should:
A) suction his oropharynx at once.
B) turn the patient onto his side.
C) insert an oropharyngeal airway.

,D) begin assisting his ventilations. - 🧠 ANSWER ✔✔B) turn the patient onto his
side.
The patient's airway must be clear of foreign bodies or secretions before it can be
assessed or managed. If the patient begins to vomit, he must first be rolled
onto his side to allow for drainage of the vomitus. Use suction to remove secretions
after you have positioned him on his side. After the airway is clear, you
should insert an appropriate airway adjunct (oral or nasal airway) and ensure
adequate ventilation and oxygenation. In this patient, this involves assisting his
ventilations with a bag-valve-mask device.
The method by which you administer supplemental oxygen to a hypoxemic patient
depends MOSTLY on the:
A) presence or absence of cyanosis.
B) patient's level of consciousness and heart rate.
C) suspected underlying cause of the hypoxemia.
D) severity of hypoxemia and adequacy of breathing. - 🧠 ANSWER ✔✔D)
severity of hypoxemia and adequacy of breathing.

, All hypoxemic patients, whatever the cause of their condition, should be treated
with supplemental oxygen. The method of oxygen delivery depends on the
severity of the hypoxemia and the adequacy of the patient's breathing. For
example, a hypoxemic patient who is breathing adequately (eg, normal rate,
adequate tidal volume) should receive oxygen via nasal cannula or nonrebreathing
mask, depending on the severity of the hypoxemia. However, if the patient
is breathing inadequately (eg, fast or slow rate, shallow breathing [reduced tidal
volume]), he or she may require ventilation assistance with a bag-valve-mask
device. The absence of cyanosis does not rule out hypoxia; cyanosis is a later sign
and indicates significant hemoglobin desaturation. A patient's level of
consciousness and heart rate can give you clues as to the severity of his or her
hypoxemia; a decreased level of consciousness and a rapid, weak pulse rate
are signs of significant hypoxemia.
Assessment of a 40-year-old patient reveals respiratory distress, tachycardia,
audible expiratory wheezing, and an oxygen saturation of 88%.
The EMT should suspect:
A) fluid in the lower airways.
