Assessment of a patient with respiratory distress reveals that his
expiratory phase is 4 times longer than his inspiratory phase. Which of
the following conditions would MOST likely cause this? - CORRECT
ANSWER✔✔Bronchospasm
Which of the following occurs when a patient is hypoventilating? -
CORRECT ANSWER✔✔Increased PaCO2, decreased PaO2, decreased
pH
A hiker was bitten on the leg by a rattlesnake approximately 20
minutes ago. He complains of pain to the lateral aspect of his left leg,
just proximal to the ankle. Assessment of that area reveals two small
puncture wounds surrounded by edema. You also note localized
twitching of his calf muscles. He is conscious and alert, but anxious.
His blood pressure is 112/70 mm Hg, pulse is 120 beats/min, and
respirations are 24 breaths/min with adequate depth. In addition to
keeping him calm, you should: - CORRECT ANSWER✔✔administer high-
flow oxygen via nonrebreathing mask, apply a sterile dressing to the
wound, immobilize his leg and keep it below the level of the heart,
start an IV line and set it at a KVO rate, and transport.
A 56-year-old male presents with respiratory distress. He appears tired
and is slow to answer your questions. He is taking a series of quick
,breaths, followed by prolonged exhalation. On the basis of these
clinical findings, you should: - CORRECT ANSWER✔✔provide some form
of positive-pressure ventilation.
A 49-year-old man presents with acute shortness of breath. He is
conscious, but confused, and is gasping for air. The pulse oximeter
reads 79% on room air. Initial management should consist of: -
CORRECT ANSWER✔✔some form of ventilatory assistance.
You are ventilating an intubated patient and note decreased
compliance with each delivered ventilation. Which of the following
conditions would be the LEAST likely cause of this? - CORRECT
ANSWER✔✔Beta-2 receptor stimulation
When administering oxygen via nasal cannula during a long-range
transport, you should: - CORRECT ANSWER✔✔attach an oxygen
humidifier.
A 70-year-old male presents with confusion, a blood pressure of 74/56
mm Hg, and a pulse of 80 beats/min and weak. His son tells you that
he has had black tarry stools for the past 3 days, but refused to go to
the hospital. He further tells you that his father has hypertension and
Alzheimer's disease, and hands you a medication list that includes
Toprol, Zestril, Seroquel, and vitamins. You should be MOST concerned
that this patient: - CORRECT ANSWER✔✔is hypoperfused.
A 30-year-old man overdosed on codeine and has respirations of 6
breaths/min and shallow. Which of the following conditions will he
develop initially? - CORRECT ANSWER✔✔Respiratory acidosis
When performing tracheobronchial suctioning on an adult, it is
important to - CORRECT ANSWER✔✔monitor the patient's oxygen
saturation and cardiac rhythm
What is the approximate minute alveolar volume of a patient who
breathes in 550 mL of air at a rate of 14 times per minute - CORRECT
ANSWER✔✔5.4 L (Approximately 30% of a person's tidal volume (or
about 1 mL per pound of body weight) lingers in the anatomic dead
, space (eg, trachea, larger bronchi) and does not reach the lungs to
participate in gas exchange. Therefore, a patient with an alveolar
volume of 385 mL (550 - 165 [30% of 550] = 385) and a respiratory rate
of 14 breaths/min has an approximate minute alveolar volume of 5.4 L
(385 × 14 = 5,390 mL [5.4 L]).)
A trauma patient is being transferred from one facility to another. The
patient is intubated and is on a mechanical transport ventilator. During
transport, the high-pressure alarm sounds on the ventilator. Which of
the following would MOST likely cause this? - CORRECT
ANSWER✔✔The ET tube is in the right mainstem bronchus
After determining that your unresponsive patient has a severe
(complete) upper airway obstruction caused by a foreign body, you
should: - CORRECT ANSWER✔✔perform chest compressions
When arterial oxygen levels in the body fall, chemoreceptors in the
brain send messages to the diaphragm via the - CORRECT
ANSWER✔✔phrenic nerve.
A 40-year-old woman who was recently discharged from the hospital
reports a sudden onset of difficulty breathing and sharp chest pain
that increases with breathing. Her skin remains cyanotic and her
oxygen saturation remains low, despite high-flow oxygen. Which of the
following is this patient MOST likely experiencing? - CORRECT
ANSWER✔✔Acute pulmonary embolism
You are treating a 50-year-old male who ingested a significant amount
of his prescribed propranolol. He is unresponsive, bradycardic,
hypotensive, and has poor respiratory effort. In addition to assisting
his ventilations, applying a cardiac monitor, and establishing vascular
access, the MOST appropriate treatment for him includes: - CORRECT
ANSWER✔✔cardiac pacing, glucagon, and a vasopressor.
Immediately after placing an endotracheal tube in the trachea of an
adult, the paramedic should: - CORRECT ANSWER✔✔inflate the distal
cuff with 5 to 10 mL of air.
