The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

  • A. BP 142/88 mmHg
  • B. 2+ edema of fingers and hands
  • C. Radial pulse volume is +3
  • D. Capillary refill time is 2 seconds
Correct Answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.
