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 ["A","B","C"]
Explanation
Choice A rationale
Monitoring the client’s white blood cell count is essential to assess the presence and severity of infection. An elevated white blood cell count can indicate an ongoing infection, including MRSA.
Choice B rationale
Sending wound drainage for culture and sensitivity is crucial to identify the specific bacteria causing the infection and to determine the most effective antibiotics for treatment.
Choice C rationale
Instituting contact precautions for staff and visitors is necessary to prevent the spread of MRSA. This includes wearing gloves and gowns when entering the client’s room and ensuring proper hand hygiene.
Choice D rationale
Explaining the purpose of a low bacteria diet is not relevant to the management of MRSA infections. MRSA management focuses on infection control measures and appropriate antibiotic therapy.
Choice E rationale
Using standard precautions and wearing a mask is not specific to MRSA management. While standard precautions are always important, contact precautions are more relevant for preventing the spread of MRSA.
Correct Answer is D
Explanation
Choice A rationale
Providing a back rub at bedtime can help promote relaxation and improve sleep quality. However, it does not directly address the issue of wandering, which poses a safety risk for the client. The primary concern should be ensuring the client’s safety by preventing wandering.
Choice B rationale
Applying wrist restraints to prevent wandering is not an appropriate first intervention. Restraints should be used as a last resort when other measures have failed, and they can cause physical and psychological harm to the client. The focus should be on non-restrictive interventions to ensure safety.
Choice C rationale
Administering a PRN sedative prescription may help the client sleep, but it should not be the first intervention. Sedatives can have side effects and may not address the underlying cause of the client’s wandering. Non-pharmacological interventions should be tried first.
Choice D rationale
Leaving the door to the client’s room open slightly allows the client to see and hear staff members as they pass by, which can help reduce feelings of isolation and anxiety. This intervention addresses both the client’s sleep issues and wandering behavior by providing a sense of security and supervision.
