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 B
Explanation
Choice A rationale
Testing for a gag reflex before performing oral care is a standard practice to ensure the client’s safety and prevent aspiration. This action does not indicate a need for additional training.
Choice B rationale
Placing the client in a supine position is incorrect and indicates a need for additional training. The correct position for performing oral care on an unconscious client is a side-lying position to prevent aspiration and ensure secretions can drain from the mouth.
Choice C rationale
Suctioning secretions from the posterior pharynx is a necessary action to maintain airway patency and prevent aspiration. This action does not indicate a need for additional training.
Choice D rationale
Using an oral airway to keep the teeth apart is a standard practice to facilitate oral care and prevent the client from biting down on the caregiver’s fingers or equipment. This action does not indicate a need for additional training.
Correct Answer is A
Explanation
Choice A rationale
Reporting the client’s status to the healthcare provider is the appropriate action. The healthcare provider needs to be informed of the client’s death to provide further instructions and complete necessary documentation. This action ensures proper communication and adherence to protocols.
Choice B rationale
Asking the UAP to complete postmortem care is necessary, but it should be done after notifying the healthcare provider. The nurse must follow the proper sequence of actions to ensure all protocols are followed.
Choice C rationale
Beginning cardiopulmonary resuscitation (CPR) and calling a code is not appropriate because the client has a signed do not resuscitate (DNR) form. Performing CPR would go against the client’s wishes and legal documentation.
Choice D rationale
Notifying the family of the client’s death is important, but it should be done after reporting the client’s status to the healthcare provider. The healthcare provider may have specific instructions for communicating with the family and completing necessary documentation.
