The nurse attaches a pulse oximeter to a client’s finger and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
Capillary refill time is 2 seconds.
2+ edema of fingers and hands.
Radial pulse volume is 3+.
Blood pressure is 142/88 mm Hg.
The Correct Answer is B
Choice A rationale
Capillary refill time is 2 seconds. A capillary refill time of 2 seconds is within normal limits and is unlikely to affect the accuracy of the pulse oximetry reading.
Choice B rationale
2+ edema of fingers and hands. Edema can interfere with the accuracy of pulse oximetry readings by affecting the perfusion of the area where the sensor is placed. This can lead to falsely low oxygen saturation readings.
Choice C rationale
Radial pulse volume is 3+. A strong radial pulse indicates good peripheral perfusion, which should not negatively impact the accuracy of the pulse oximetry reading.
Choice D rationale
Blood pressure is 142/88 mm Hg. While elevated blood pressure can have various effects on the body, it is not likely to directly affect the accuracy of a pulse oximetry reading.

Correct Answer is D
Explanation
Choice A rationale
Risk for infection is a concern for clients with neuropathy, as they may have reduced sensation and be unaware of injuries that can become infected. However, the primary concern in promoting foot care is preventing the occurrence of wounds or skin breakdown in the first place.
Choice B rationale
Self-care deficit is relevant for clients with neuropathy who may have difficulty performing foot care independently. However, the priority is to prevent skin breakdown and wounds, which can lead to more severe complications.
Choice C rationale
Impaired physical mobility is a common issue for clients with neuropathy, but it is not the primary concern for foot care. The focus should be on preventing skin breakdown and ensuring proper foot care to avoid complications.
Choice D rationale
Risk for impaired skin integrity is the priority for promoting foot care in clients with neuropathy. Neuropathy can compromise the ability to detect injuries or wounds on the feet, leading to unnoticed wounds that can become infected and cause serious complications.
Preventing skin breakdown and maintaining skin integrity is crucial in this scenario.
Correct Answer is C
Explanation
Choice A rationale
Releasing the manometer valve immediately is not appropriate as it does not allow for an accurate measurement of systolic blood pressure.
Choice B rationale
Documenting the absence of the radial pulse is not the correct action. The nurse needs to continue the procedure to obtain an accurate systolic blood pressure reading.
Choice C rationale
Inflating the blood pressure cuff to 120 mm Hg is the correct action. The nurse should inflate the cuff 30 mm Hg above the point where the radial pulse is no longer palpable to ensure an accurate measurement.
Choice D rationale
Recording a palpable systolic pressure of 90 mm Hg is incorrect. The nurse needs to inflate the cuff further to obtain an accurate systolic blood pressure reading.
