Q. 4  The respiratory therapist is assessing a patient with sinus tachycardia. Which of the following would LEAST likely be a cause of the sinus tachycardia?
 
  a. hypoxemia
  b. severe anemia
  c. hyperthermia
  d. massive hemorrhage
  e. beta blocker medications

(Answer to Q. 1)  A
Obstructive sleep apnea is associated with insomnia, excessive daytime sleepiness, and other signs and symptoms. Hypothyroidism and other clinical disorders are associated with central sleep apnea. Metabolic alkalosis is not associated with obstructive sleep apnea.

(Answer to Q. 2)  B
A newborn with a CDH will have diminished breath sounds and heart sounds on the right side of the chest. A scaphoid abdomen is seen when the stomach and intestines have moved into the thoracic cavity.

(Answer to Q. 3)  A
Bracing is the primary treatment for adolescent idiopathic scoliosis (AIS).

(Answer to Q. 4)  E
Common abnormal causes of sinus tachycardia include hypoxemia, severe anemia, hyperthermia, massive hemorrhage, pain, fear, anxiety, hyperthyroidism, and sympathomimetic or parasympatholytic drug administration. Beta blocker medication may lead to sinus bradycardia, not sinus tachycardia.
