A 6-year-old boy has been brought to the emergency department by ambulance after his mother discovered that his heart rate was so fast I couldn't even count it.
 
  The child was determined to be in atrial flutter, and his mother is seeking an explanation from the health care team. Which of the following points should underlie an explanation to the mother?
  A)
  The child is experiencing a reentry rhythm in his right atrium.
  B)
  The resolution of the problem is dependent on spontaneous recovery and is resistant to pacing interventions.
  C)
  The child is likely to have a normal ECG apart from the rapid heart rate.
  D)
  The boy's atria are experiencing abnormal sympathetic stimulation.

Question 2

A 51-year-old female client who is 2 days postoperative in a surgical unit of a hospital is at risk of developing atelectasis as a result of being largely immobile. Which of the following teaching points by her nurse is most appropriate?
 
  A)
  Being in bed increases the risk of fluid accumulating between your lungs and their lining, so it's important for you to change positions often.
  B)
  You should breathe deeply and cough to help your lungs expand as much as possible while you're in bed.
  C)
  Make sure that you stay hydrated and walk as soon as possible to avoid us having to insert a chest tube.
  D)
  I'll proscribe bronchodilator medications that will help open up your airways and allow more oxygen in.

Answer to Question 1

Ans:
A

Feedback:

Atrial flutter is caused by a reentry rhythm that is located in the right atrium. It is normally responsive to pacing. His ECG will appear highly irregular, and the problem does not originate from sympathetic stimulation.

Answer to Question 2

Ans:
B

Feedback:

Atelectasis is characterized by incomplete lung expansion and can often be prevented by deep breathing and coughing. Pleural effusion, not atelectasis, is associated with fluid accumulation between the lungs and their lining, and neither chest tube insertion nor bronchodilators are common treatments for atelectasis.
