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
Positioning the head with the chin tilted slightly downward is an appropriate action when feeding a client with a CVA. This position helps prevent aspiration by closing the airway and directing food away from the trachea.
Choice B rationale
Allowing 30 minutes of rest before feeding is an appropriate action. Resting before feeding can help improve digestion and reduce the risk of aspiration by ensuring the client is alert and responsive during feeding.
Choice C rationale
Placing food on the unaffected side of the mouth is an appropriate action when feeding a client with a CVA. This technique helps the client manage food more effectively and reduces the risk of aspiration.
Choice D rationale
Raising the head of the bed to 60 degrees is not sufficient to prevent aspiration. The head of the bed should be elevated 45 to 90 degrees to ensure proper positioning and reduce the risk of aspiration. Therefore, if the UAP raises the head of the bed to only 60 degrees, it indicates the need for additional teaching.
Correct Answer is A
Explanation
Choice A rationale
Beginning with questions that are less sensitive in nature helps build rapport and makes the client more comfortable. This approach gradually leads to more sensitive topics, reducing anxiety and promoting honest responses.
Choice B rationale
Getting the most difficult questions over with first can increase the client’s anxiety and discomfort, leading to less honest or incomplete answers. It is not an effective strategy for sensitive topics.
Choice C rationale
Sharing personal values to put the client at ease can introduce bias and affect the client’s responses. It is important to remain neutral and nonjudgmental.
Choice D rationale
Asking questions in a vague, non-specific format can lead to misunderstandings and incomplete information. Clear, direct questions are more effective for gathering accurate information.
