  1. Position patients in semi-recumbent position.
  2. Insert the feeding tube into the duodenum.
  3. Suction above the tracheal tube cuff.
  4. Provide continuous aspiration of subglottic secretions.
  a. 1 only
  b. 1 and 2 only
  c. 1, 2, 3, and 4
  d. 2, 3, and 4 only

Answer to Question 1

ANS: B
The suction pressure should be set at the lowest effective level. Negative pressures of 80 to 100 mm Hg in neonates and less than 150 mm Hg in adults are generally recommended.

Answer to Question 2

ANS: C
Ideally, the patient should be switched to a tube that continually aspirates subglottic secretions. If this is not possible, oropharyngeal suctioning (above the tube cuff) should be performed as needed. To decrease the possibility of aspiration with feedings, the head of the bed should be elevated 30 degrees when possible. Also, the feeding tube can be inserted into the duodenum, with its position confirmed by radiograph. The use of slightly higher cuff pressure during and after feedings may also minimize aspiration.
