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
Advising the UAP to wear a standard face mask to obtain vital signs and then get fitted for a filter mask before providing personal care is not appropriate. The UAP should be properly equipped with the correct protective gear before any contact with the client.
Choice B rationale
Instructing the UAP that a standard face mask is sufficient to provide care for the assigned client is incorrect. Bacterial meningitis requires droplet precautions, and a standard face mask is sufficient for this type of precaution, not a particulate filter mask.
Choice C rationale
Sending the UAP to be fitted for a particulate filter mask immediately so the UAP can provide care to this client is unnecessary because bacterial meningitis requires droplet precautions, which only necessitate a standard surgical mask, not a particulate filter mask like an N953.
Choice D rationale
Before changing assignments, determining which staff members have fitted particulate filter masks is prudent but not necessary for caring for a client with bacterial meningitis under droplet precautions. The focus should be on ensuring the UAP understands that a standard mask is sufficient.
Correct Answer is A
Explanation
Choice A rationale
Placing a client in restraints without having a healthcare provider’s order is a violation of patient rights and safety protocols. Restraints should only be used when absolutely necessary and with proper authorization to ensure the safety and well-being of the patient. Unauthorized use of restraints can lead to physical and psychological harm, and it is essential to follow established guidelines and obtain the necessary orders before applying restraints.
Choice B rationale
Administering the medication to a client behind a closed curtain is not a violation. This action ensures the client’s privacy and dignity during the administration of medication. Maintaining privacy is a standard practice in healthcare settings to respect the patient’s confidentiality and comfort.
Choice C rationale
Informing a client that the medication being administered is a vitamin is a violation of ethical and legal standards. It is essential to provide accurate information to the patient about the medication being administered. Misleading the patient can undermine trust and lead to potential harm if the patient has allergies or contraindications to the medication.
Choice D rationale
Enlisting security personnel to assist with restraining the client is not a violation if done appropriately. In situations where the client poses a danger to themselves or others, it may be necessary to involve security personnel to ensure safety. However, this should be done following proper protocols and with the necessary orders in place.
