As the RN is suctioning a client, the pulse oximetry reading drops to 83%. What should the nurse do?

1. Allow the client to take some extra deep breaths.
2. Continue to suction but only intermittently.
3. Keep the catheter in place and wait a few minutes.
4. Stop suctioning and give supplemental oxygen.

ANSWER

Correct Answer: 4
Rationale 1: Allowing the client to take a few deep breaths will help but not quickly enough to compensate for the hypoxia experienced.
Rationale 2: Continuing to suction continuously or intermittently will only decrease the saturation levels more.
Rationale 3: Leaving the catheter in place obstructs air flow, thus compromising an already poor situation.
Rationale 4: Not only does suctioning remove secretions, but it also removes the client’s air. By stopping suctioning, the RN stops removing both. This allows the client to recoup from the procedure, and giving oxygen will also increase the saturation ability back to a normal range.
