ANSWERED 100% CORRECT) 2023 -2024

Which of these statements is most correct regarding the difference between respiration and ventilation?

• Ventilation describes the exchange of gases at the cellular level, while respiration

describes the same process between the lungs and the external environment

• Ventilation describes the absorption of O2 into the cells, while ventilation is the

excretion of CO2 from the cells

• Respiration describes the exchange of O2 and CO2, while ventilation describes

the movement of air that carries them into and out of the body

• Respiration and ventilation are similar terms that both describe normal and

healthy breathing in the living organism

When does hypoxia occur?

• If inadequate amounts of O2 are available to the cells
• When carbon dioxide accumulates within the body
• If the respiratory rate decreases to less than 12 breaths per minute
• When carbon dioxide is excreted too rapidly from the lungs

You have been called for a patient who has overdosed on drugs and alcohol. The patient is responsive to painful stimuli, has shallow respirations and is breathing at a rate of 8 times per minute, but exhibits no cyanosis. What is the priority treatment?

• Inadequate respirations; start positive pressure ventilation with supplemental

oxygen

• Adequate breathing; administer oxygen at 15 lpm through a nonrebreather face

mask

• Inadequate breathing; administer oxygen at 15 lpm through a nonrebreather face

mask

• Adequate breathing; initiate positive pressure ventilation with supplemental

oxygen 1 / 3

A 2-year-old boy who just seized must have his airway opened. When performing

the head-tilt, chin-lift airway maneuver, the EMT must remember:

• The head must be flexed forward
• A towel roll should be placed under the head
• If necessary, the head should be only slightly extended
• The head must be hyperextended

You must suction frothy secretions from the mouth and pharynx of a 31-year-old male patient whose respiration rate is 4 breaths/min. Which process to do so is most appropriate given the patient's condition?

• Use a soft-tip catheter and suction for no more than 30 seconds before providing

additional oxygen with a nonrebreather face mask

• Suction for no more than 15 seconds at a time, followed by 2 minutes of positive

pressure ventilation

• Place the patient into a side-lying position and alternate 30 seconds of suctioning

and ventilation

• Forego suctioning and continue to provide positive pressure ventilation, as frothy

secretions rarely complicate the airway

Which of these is a correct statement about the ventilation of a nonbreathing patient through a stoma?

• A nasal airway should be inserted into the stoma prior to any attempt at

ventilating the patient

• The EMT should ventilate through the stoma with a child-sized face mask

attached to a bag-valve mask

• Mouth-to-stoma ventilation is an easy and safe procedure to perform on a

nonbreathing patient

• A head-tilt, chin-lift maneuver or jaw-thrust airway maneuver is still needed to

open the airway

You are checking the D oxygen tank in the ambulance and note that the reading on the pressure regulator is 1000 psi. You should recognize that the tank is: 2 / 3

• Almost empty
• Leaking
• Overfilled
• Half full

A patient with a stoma and tracheostomy tube is responsive to painful stimuli. He has shallow respirations and is breathing at a rate of 6 times per minute. He has cyanosis of the fingertips and a weak, rapid radial pulse. Which strategy should be used in providing respiratory care to this patient?

• Use a continuous positive airway pressure device over the stoma
• Attach the bag-valve device directly to the tracheostomy tube
• Place a tracheostomy mask over the tube and administer high-concentration

oxygen

• Remove the tracheostomy tube, place a child-size mask on the bag-valve device,

and ventilate the patient through the stoma

A patient who inhaled superheated steam in an industrial fire is most likely to exhibit which abnormal upper airway noise?

• Stridor
• Snoring
• Gurgling
• Wheezing

Your paramedic partner has applied continuous positive airway pressure (CPAP) to a patient in respiratory distress from congestive heart failure (CHF). As an EMT, you

realize that this treatment should benefit the patient by:

• Collapsing portions of the diaphragm
• Causing the diaphragm to relax during inspiration
• Removing air from the lungs during exhalation
• Displacing fluid in the alveoli back into the bloodstream
