Exam 44: Atelectasis

After gastric bypass surgery, a patient is showing tachypnea. What is the best explanation for this?

Which of the following is (are) precipitating factor(s) that can decrease the patient's ability to generate a negative intrapleural pressure? 1) Supine position 2) Large tidal volume on the mechanical ventilator 3) Malnutrition 4) Obesity

Which of the following are precipitating factors for retained secretions that commonly lead to atelectasis? 1) Asthma 2) General anesthesia 3) Gastric aspiration 4) Smoking history

Several pathophysiologic mechanisms operating simultaneously may lead to an increased ventilatory rate. These may include all of the following EXCEPT:

Examples of the types of surgical procedures that often result in atelectasis include all of the following EXCEPT:

Which of the following is the least commonly found type of postoperative atelectasis?

Common chest assessment findings in a patient with atelectasis include: 1) increased tactile fremitus. 2) dull percussion note. 3) crackles. 4) bronchial breath sounds.

After open heart surgery, a patient has developed bronchitis with increased secretions and atelectasis. What respiratory therapy procedure(s) should initially be recommended? 1) Chest physical therapy 2) Continuous positive airway pressure (CPAP) 3) Incentive spirometry 4) Inhaled sympathomimetic medication

A 40-year-old patient was in a motor vehicle accident. Among his injuries and related problems are three broken ribs on the right side, pleural fluid in the right pleural space, and atelectasis of both lungs. What should be done to help with the atelectasis problem? 1) Adequate pain management 2) Mechanical ventilation to stabilize the broken ribs 3) Remove the pleural fluid 4) Selective intubation of the right mainstem bronchus

A patient with atelectasis is being monitored by bedside spirometry. What findings would correspond with atelectasis? 1) Decreased IC 2) Increased PEFR 3) Decreased VC 4) Increased DLCO

All of the following conditions can lead to atelectasis EXCEPT:

What definition of atelectasis would best fit that of a premature newborn with respiratory distress syndrome (RDS)?

A patient has a tumor blocking the left mainstem bronchus. What additional factor would favor the development of atelectasis?

Precipitating factors for retained secretions include all of the following EXCEPT:

Which of the following patients should be placed on short-term mechanical ventilation because of the high risk of postoperative atelectasis?

After surgery, a patient must lie supine in bed. Because of this, atelectasis is thought to have developed. What chest radiograph finding would confirm this?

All of the following would be found in a patient with atelectasis EXCEPT:

The respiratory therapist is performing chest assessment on a post-op cholecystectomy patient who has developed cough, fever, and tachypnea. Which of the following would the therapist expect to find confirming the suspicion of post-op atelectasis in this patient?
