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 C
Explanation
Choice A rationale
Telling the parents that their child’s medical information is none of their business is not appropriate. It is important to communicate respectfully and explain the legal status of the emancipated minor.
Choice B rationale
Promising to give the results to the parents as soon as they are back from the laboratory is not appropriate. The nurse should respect the legal status of the emancipated minor and their right to privacy.
Choice C rationale
Informing the parents that the nurse can only give medical information to their child because they are legally an adult is the best response. This explains the legal status of the emancipated minor and respects their autonomy.
Choice D rationale
Telling the parents that the healthcare provider will share the information with them is not appropriate. The nurse should respect the legal status of the emancipated minor and their right to privacy.
Correct Answer is D
Explanation
Choice A rationale
Completing an adverse occurrence/incident report is important if an incident occurs, but it does not address the immediate issue of improper restraint application. The priority is to correct the UAP’s action to prevent potential harm to the client.
Choice B rationale
Ensuring that the restraints are not too tight is important for the client’s safety and comfort, but it does not address the improper securing of the restraints to the bedside rails. The restraints should be secured to a movable part of the bed frame, not the rails.
Choice C rationale
Initiating the facility’s restraint flow sheet is necessary for documentation, but it does not address the immediate issue of improper restraint application. The priority is to correct the UAP’s action to prevent potential harm to the client.
Choice D rationale
Demonstrating proper securing of the restraints is the most important action because it educates the UAP and prevents potential complications such as injury, infection, or circulation impairment. The nurse should show the UAP how to secure the restraints to a movable part of the bed frame, not to the rails.
