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
Requesting removal initiated by the Health Information Manager is not necessary in this scenario. The focus should be on accurately documenting the missed occurrence rather than removing previously entered documentation. This approach does not address the need to document the 0900 occurrence.
Choice B rationale
Creating an electronic correction after 1400 notes are officially unlocked implies that there was an error in the original documentation. Since the issue here is not correcting an error but rather adding missed documentation, creating a correction may not be appropriate.
Choice C rationale
Entering the occurrence after the 1400 notes and identifying it as a “late entry” is an option, but it may not provide sufficient clarity regarding the timing of the documentation. Using a “late entry” label could potentially lead to confusion or misinterpretation.
Choice D rationale
Making an electronic addendum following the 1400 documentation is the best approach. An electronic addendum allows the nurse to add additional information to the chart without altering the original entry. This approach maintains the integrity of the original documentation while clearly indicating that the 0900 occurrence was added after the fact. It ensures accuracy and transparency in the medical record.
Correct Answer is A
Explanation
Choice A rationale
Starting to collect the specimen with the next void is the correct action. The 24-hour urine collection for creatinine clearance should start with an empty bladder. The first urine of the day is discarded, and the time is noted.
Choice B rationale
Beginning the collection the next day is unnecessary and would delay the process. It is important to start the collection as soon as possible to avoid further delays.
Choice C rationale
Observing the sample for sediment is not relevant to the collection process. The focus should be on starting the collection with the next void.
Choice D rationale
Emptying the sample into the 24-hour container is incorrect because the first urine sample should be discarded to ensure accurate results.
