Chapter 10 Homework
For pulmonary and cellular respiration to work efficiently, what must also be functioning?
Cardiovascular System.
A sign of inadequate breathing requiring artificial ventilation is:
Chest movements that are absent, minimal, or uneven.
What must be done before providing ventilations through a stoma?
Clear any mucus or secretions from the stoma.
If you can't ventilate effectively through a stoma, what is another option?
Consider sealing the stoma and attempting artificial ventilation.
In calculating alveolar ventilation, what must be subtracted from what?
Dead air space from tidal colume.
When delivering oxygen via a nonrebreather mask, you are:
Delivering a higher concentration of oxygen than possible with a nasal cannula.
Oxygen must be circulated through the body, and carbon dioxide must be:
Eliminated from the body.
You are attempting to ventilate an unresponsive patient. What is it NOT necessary to do with this patient?
Explain the procedure to the patient.
What is least reliable as a sign of respiratory arrest in a patient?
Gasping
Which type of flowmeter are you likely to use in the field only in connection with oxygen-powered devices such as respirators and ventilators?
High-pressure.
If you will be transporting a patient to a hospital hours away, and the patient requires supplemental oxygen, which of the following will likely make the patient more comfortable?
Humidified Oxygen.
An insufficient supply of oxygen to the body's tissues is known as:
Hypoxia.
After a patient has been intubated with an endotracheal tube, you should hear sounds:
In both lungs but no in the same epigastrium.
You arrive on scene as your patient becomes unconscious and stops breathing. His pulse is palpable at a rate of 48 per minute. How would you classify this patient?
Respiratory Arrest.
A patient ceasing to be able to speak is most likely a sign of:
Respiratory Failure.
You are caring for a 3-year-old boy who presents with a decreased level of consciousness and slow, irregular breathing. His skin is cyanotic. How would you classify this patient?
Respiratory Failure.
Minute volume is determined primarily by:
Respiratory Rate and Tidal Volume.
Under typical circumstances, skin may be pale and blue in:
Respiratory failure and respiratory arrest.
When calculating the duration of flow for an M cylinder, what would you use as the cylinder constant?
1.56.
How often should a breath be provided to the adult patient who has a pulse when using a bag-valve mask attached to supplemental oxygen?
5 Seconds.
What is the approximate amount of oxygen in a G cylinder?
5,300 liters.
Properly utilized, the non rebreather mask can typically deliver what percent of oxygen concentration?
80% to 100%
In which of the following transport situations is an oxygen humidifier recommended?
A long transport time.
Which of the following patients is most likely to be hypoxic?
A patient who has overdosed on a respiratory depressant medication and is unresponsive
Which of the following patients is at risk for failure of the cardiopulmonary system?
A patient who hit the steering wheel of a car with her chest at 90 mph.
Which of the following patients is most likely hypoxic?
A patient who was trapped in a fire for an extended time period.
Which of the following patients is a risk for failure of the cardiopulmonary system?
A patient with an exacerbation of congestive heart failure.
What is a permanent surgical opening in the neck through which the patient breathes?
A stoma.
Which of the following may lead to hyperventilation of an apneic adult patient with a pulse?
A ventilation rate of 22 per minute.
For an adult patient with very slow ventilations, you should:
Add ventilations in between the patient's own.
What may prevent you from intervening to treat a life-threatening respiratory problem?
Airway Issues.
Assuming no change in respiratory rate, what happens if the tidal volume is decreased?
Alveolar Ventilation Decreases
The amount of air that enters the alveoli for gas exchange is referred to as:
Alveolar Ventilation.
When a person inhales, the diaphragm:
And the intercostal muscles contract.
When helping a paramedic visualize the vocal cords, the EMT should use the:
BURP Maneuver.
In which of the following situations does the chest expand and the diaphragm contract, creating a negative intrathoracic pressure?
Inhalation.
What happens with oxygen and carbon dioxide during the process of pulmonary respiration?
Oxygen is loaded into the hemoglobin of the blood from the alveoli, and carbon dioxide is off-loaded from the blood into the alveoli.
What type of oxygen mask is generally not used in EMS and may be used to keep CO2 levels up?
Partial rebreather mask.
When preparing an oxygen delivery system, after you selected the correct pressure regulator and flowmeter, you would:
Place the cylinder valve gasket on the regulator oxygen port.
Which situation best indicates the need for an automatic transport ventilator (ATV)?
Prolonged ventilation necessary, one rescuer.
What primarily differentiates a patient with adequate breathing from a patient with inadequate breathing?
The body of a patient with adequate breathing is still able to compensate for increasing oxygen demand, but the body of a patient with inadequate breathing is no longer able to compensate.
When ventilating a patient, you should see:
The chest rise and fall with each ventilation.
Hyperventilation is related to:
The rate at which the EMT ventilates the patient.
The preferred method of artificial ventilation is:
Tow-Rescuer BVM.
With patients in respiratory arrest, always remember to:
Ventilate rather than oxygenate.
A device that is used to deliver specific oxygen concentrations for the patient who needs low to moderate concentrations of oxygen is a:
Venturi Mask.
Which of the following signs indicates the need for assisted ventilations in a patient with breathing difficulty?
Very Diaphoretic.
Alveolar ventilation can be altered through changes in rate as well as by changes in:
Volume
A nasal cannula should be used to administer oxygen to a patient:
Who needs only small amounts of oxygen.
Which of the following statements is true of mouth-to-mask ventilations?
Without supplemental oxygen, they deliver 16% oxygen.
