Flashcards in Respiratory Pop Deck (18):
A 21-year-old man experienced an acute onset of pleuritic chest pain and dyspnea while playing softball. He is noticeably dyspneic, has an oxygen saturation of 93% on room air, and has diminished breath sounds to the upper right lobe. The MOST appropriate treatment for this patient involves:
A. performing a needle decompression to the right side of his chest.
B. applying a CPAP unit and starting an IV line en route to the hospital.
C. assisting his ventilations in order to increase his oxygen saturation.
D. administering high-flow supplemental oxygen and transporting at once.
A patient who is coughing up thick pulmonary secretions should NOT take:
A. a diuretic.
B. an antitussive.
Which of the following medications is a parasympathetic bronchodilator?
Cor pulmonale is defined as:
A. rupture of the alveoli due to increased surface tension.
B. increased preload caused by severe hypertension.
C. right heart failure secondary to chronic lung disease.
D. left heart failure secondary to mitral valve damage.
A 36-year-old man with a history of asthma presents with severe respiratory distress. You attempt to administer a nebulized beta-2 agonist, but his poor respiratory effort is inhibiting effective drug delivery via the nebulizer and his mental status is deteriorating. You should:
A. start an IV of normal saline and administer a steroid.
B. apply high-flow oxygen via a nonrebreathing mask.
C. assist his ventilations and establish vascular access.
D. assist him with a metered-dose inhaler bronchodilator.
Apneustic breathing is characterized by:
A. regular respirations with a normal rate and adequate tidal volume.
B. short, brisk inhalations with a long pause before exhalation.
C. a crescendo-decrescendo pattern of breathing with apneic periods.
D. a sustained pattern of tachypnea and increased tidal volume.
An unresponsive patient who overdosed on a central nervous system depressant drug would be expected to have __________ respirations.
A patient who is coughing up purulent sputum is MOST likely experiencing:
A. pulmonary edema.
D. an infection.
Difficulty with exhalation is MOST characteristic of:
A. a mild asthma attack.
B. upper airway obstruction.
C. supraglottic swelling.
D. obstructive lung disease.
Reactive airway disease is characterized by:
A. acute, reversible swelling of the laryngeal muscles.
B. bronchospasm, edema, and mucus production.
C. chronic bronchoconstriction of varying severity.
D. excessive mucus production and a chronic cough.
A morbidly obese man called 9-1-1 because of difficulty breathing. When you arrive, you find the 39-year-old patient lying supine in his bed. He is in marked respiratory distress and is only able to speak in two-word sentences. He has a history of hypertension, but denies any respiratory conditions. What should you do FIRST?
A. Administer a beta-2 agonist drug.
B. Sit him up or place him on his side.
C. Assess his oxygen saturation level.
D. Begin assisting his ventilations.
Pickwickian syndrome is a condition in which respiratory compromise results from:
A. extreme obesity.
B. cervical spine injury.
C. pulmonary edema.
D. diaphragmatic rupture.
The MOST clinically significant finding when questioning a patient with a chronic respiratory disease is:
A. a recent medication regimen change.
B. prior intubation for the same problem.
C. medication use prior to your arrival.
D. a recent emergency department visit.
If the amount of pulmonary surfactant is decreased:
A. alveolar surface tension increases.
B. alveoli are able to expand more easily.
C. diffuse alveolar hyperinflation occurs.
D. pulmonary gas exchange is enhanced.
A patient with a history of asthma is at GREATEST risk for respiratory arrest if he or she:
A. was previously intubated for his or her condition.
B. was recently evaluated in an emergency department.
C. takes a bronchodilator and a corticosteroid.
D. has used his or her inhaler twice in the previous week.
Hepatomegaly and jugular venous distention are MOST suggestive of:
A. pulmonary edema.
B. left heart failure.
C. severe pneumonia.
D. right heart failure.
A critical step when using a CPAP unit to treat a patient with severe respiratory distress is:
A. holding the mask to the noncompliant patient's face.
B. setting the oxygen flow rate to at least 6 L/min.
C. starting with CPAP levels above 10 to 15 cm of water.
D. ensuring an adequate mask seal with minimal leakage.
