CH 13 EMT

Asthma is caused by a response of the:
immune system
Dyspnea is MOST accurately defined as:
CORRECT A)
shortness of breath or difficulty breathing.
B)
a complete cessation of respiratory effort.
C)
a marked increase in the exhalation phase.
D)
labored breathing with reduced tidal volume.
In a healthy individual, the brain stem stimulates breathing on the basis of:
increased carbon dioxide levels.
The respiratory distress that accompanies emphysema is caused by:
chronic stretching of the alveolar walls.
You are dispatched to a residence for a 67-year-old female who was awakened by shortness of breath and sharp chest pain. Her husband tells you that she was recently discharged from the hospital after having hip surgery. Your assessment reveals dried blood around her mouth, facial cyanosis, and an oxygen saturation of 88%. This patient’s presentation is MOST consistent with:
A)acute pulmonary edema.
B)right-sided heart failure.

CORRECT C)acute pulmonary embolism.

D)spontaneous pneumothorax.

At the onset of an acute asthma attack, patients commonly experience difficulty breathing and:
expiratory wheezing.
Common signs and symptoms of acute hyperventilation syndrome include:
tachypnea and tingling in the extremities.
When assessing for fluid collection in the lungs during auscultation of lung sounds, you should:
start at the lower lung fields and determine at which level you start hearing clear breath sounds.
Harsh, high-pitched inspiratory sounds are characteristic of:
stridor.
A 30-year-old male presents with acute shortness of breath, widespread hives, and facial swelling. He denies any past medical history and takes no medications. During your assessment, you hear wheezing over all lung fields. His blood pressure is 90/50 mm Hg and his heart rate is 110 beats/min. In addition to giving him 100% oxygen, the MOST important treatment for this patient is:
epinephrine.
You are assisting an asthma patient with his prescribed metered-dose inhaler. After the patient takes a deep breath and depresses the inhaler, you should:
instruct him to hold his breath for as long as he comfortably can.
When the level of arterial carbon dioxide rises above normal:
respirations increase in rate and depth.
A 22-year-old female patient is complaining of dyspnea and numbness and tingling in her hands and feet after an argument with her fiancé. Her respirations are 40 breaths/min. You should:
provide reassurance and give oxygen as needed.
Acute pulmonary edema would MOST likely develop as the result of:
toxic chemical inhalation.
A pleural effusion is MOST accurately defined as:
fluid accumulation outside the lung.
A 60-year-old male presents with acute respiratory distress. He is conscious and alert, has pink and dry skin, and has respirations of 24 breaths/min with adequate depth. Which of the following treatment modalities is MOST appropriate for this patient?
oxygen via nonrebreathing mask and a focused secondary assessment
In what area of the lungs does respiration occur?
alveoli
When auscultating the lungs of a patient with respiratory distress, you hear adventitious sounds. This means that the patient has:
abnormal breath sounds.
The two processes that occur during respiration are:
inspiration and expiration.
Weakening of the airway in patients with chronic bronchitis is the result of:
destruction of protective mechanisms that remove foreign particles.
A 59-year-old male with a history of emphysema complains of an acute worsening of his dyspnea and pleuritic chest pain following a forceful cough. Your assessment reveals that he has a barrel-shaped chest, unilaterally diminished breath sounds, and tachycardia. What is the MOST likely cause of this patient’s condition?
spontaneous pneumothorax
Hyperventilation could be associated with all of the following, EXCEPT:
CORRECT A)a narcotic overdose.
B)a respiratory infection.
C)an overdose of aspirin.
D)high blood glucose levels.
Albuterol is a generic name for:
Proventil.
A 62-year-old man with a history of congestive heart failure presents with severe respiratory distress and an oxygen saturation of 82%. When you auscultate his lungs, you hear widespread rales. He is conscious and alert, is able to follow simple commands, and can only speak in two- to three-word sentences at a time. You should:
apply a continuous positive airway pressure (CPAP) device, monitor his blood pressure, and observe him for signs of improvement or deterioration.
An alert patient presents with a regular pattern of inhalation and exhalation and breath sounds that are clear and equal on both sides of the chest. These findings are consistent with:
adequate air exchange.
Which of the following statements regarding the hypoxic drive is MOST correct?
The hypoxic drive stimulates a person to breathe on the basis of low oxygen levels.
When administering supplemental oxygen to a hypoxemic patient with a chronic lung disease, you should:
adjust the flow rate accordingly until you see symptom improvement, but be prepared to assist his or her ventilations.
A conscious and alert 29-year-old female with a history of asthma complains of difficulty breathing that began after her morning jog. The temperature outside is 40°F (5°C). On exam, you hear bilateral expiratory wheezing. After providing 100% oxygen, you should:
determine if she has been prescribed a beta-agonist inhaler.
Which of the following statements regarding severe acute respiratory syndrome (SARS) is correct?
SARS is a viral infection that often begins with flulike symptoms.
Paroxysmal nocturnal dyspnea (PND), rales, and dependent edema are clinical indicators of:
congestive heart failure.
PASTE
Progression
Associated chest pain
Sputum
Talking tiredness
Exercise tolerance
acidosis
buildup of excess acid in the blood or body tissues that results form a primary illness
adventitious breath sounds
abnormal breath sounds such as wheezes, ronchi, and rales
alkalosis
buildup of excess base in the body fluids
allergen
substance that causes an allergic reaction
anaphylaxis (anaphylactic shock)
extreme, life threatening, systematic allergic reaction that may include shock and respiratory failure
asthma
acute spasm of the smaller air passages, called bronchioles, associated with excessive mucus production and with swelling of the mucous lining of the respiratory passages
atelectasis
collapse of the alveolar air spaces of the lungs
bronchial breath sounds
normal breath sounds made by air moving through the bronchi
bronchiolitis
inflammation of the bronchioles that usually occurs in children younger than 2 years of age
