Which is an important nursing consideration when suctioning a young child who has had heart surgery?
- A. Perform suctioning at least every hour.
- B. Suction for no longer than 30 seconds at a time.
- C. Administer supplemental oxygen before and after suctioning.
- D. Expect symptoms of respiratory distress when suctioning.
Correct Answer: C
Rationale: If suctioning is indicated, supplemental oxygen is administered with a manual resuscitation bag before and after the procedure to prevent hypoxia.

Symptoms of respiratory distress are avoided by using appropriate technique.
