A nurse is preparing to suction a client. The pulse is 65 and pulse oximetry is 94%. Which finding will cause the nurse to stop suctioning?
Pulse 60
Pulse 90
Oxygen saturation of 92%
Oxygen saturation 89%
Blood pressure 130/80
The Correct Answer is D
A. A pulse of 60 is low but does not necessarily indicate a need to stop suctioning if the patient remains stable otherwise.
B. A pulse of 90 is within normal limits and does not require stopping suctioning.
C. An oxygen saturation of 92% is slightly low but still acceptable; suctioning can continue if the client is stable.
D. An oxygen saturation of 89% is below the acceptable threshold and indicates hypoxia, prompting the nurse to stop suctioning immediately to avoid further compromising the client's respiratory status.
E. A blood pressure of 130/80 is within normal limits and does not warrant cessation of suctioning.

C. The pulmonic valve closure is associated with the S2 heart sound, not S1.
D. The closure of the pulmonic and aortic valves occurs in S2, not S1.
E. This combination is incorrect, as S1 is associated with mitral and tricuspid valve closure.
