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
Sending an email to facility administrators reporting the action may not be the most immediate or effective way to address the situation. It could delay the necessary intervention and does not ensure that the issue is resolved promptly.
Choice B rationale
Warning the colleague that copying health information is unlawful is important, but it may not adequately address the potential breach of patient privacy and confidentiality. The colleague may already be aware of the laws but still engage in inappropriate behavior.
Choice C rationale
Disposing of the copies and continuing with client care assignments prevents further unauthorized access to patient information but does not address the issue of the colleague’s inappropriate handling of the records. It is essential to report the incident to the appropriate authority for further investigation and follow-up.
Choice D rationale
Communicating the colleague’s activities to the unit charge nurse is the most appropriate action because it informs the person in charge of the unit about the observed behavior, allowing for immediate intervention and potential corrective action. The unit charge nurse can address the situation promptly and ensure that patient privacy and confidentiality are maintained.
Correct Answer is A
Explanation
Choice A rationale
Verifying the placement of the pulse oximeter is the first step to ensure the accuracy of the oxygen saturation reading. An incorrect placement can lead to inaccurate readings, and addressing this issue can help determine if further interventions are needed.
Choice B rationale
Increasing the oxygen to 3 L/minute may be necessary if the oxygen saturation remains low after verifying the pulse oximeter placement. However, this should be done after ensuring the accuracy of the initial reading.
Choice C rationale
Switching to a non-rebreather mask is not the immediate action to take. Non-rebreather masks deliver a high concentration of oxygen, typically reserved for severe hypoxia. The patient’s oxygen saturation is low, but not critically low.
Choice D rationale
Removing the nasal cannula is not appropriate as it would further decrease the oxygen supply to the patient. The goal is to improve oxygenation, not reduce it.
