While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?

  • A. 70-80 mmHg
  • B. 100-120 mmHg
  • C. 150-170 mmHg
  • D. 200 mmHg
Correct Answer: B

Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.
