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
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.
Correct Answer is B
Explanation
Choice A rationale
Reporting any change in urine color is not a priority intervention for a terminally ill client who is weak, mouth breathing, and refusing anything to eat or drink. The focus should be on comfort measures.
Choice B rationale
Keeping mucous membranes moist is essential for comfort in terminally ill clients who are mouth breathing and refusing fluids. This can be achieved by offering ice chips, sips of water, or using a moist cloth.
Choice C rationale
Recording the client’s daily weight is not a priority in this situation as the client is terminally ill and the focus should be on comfort rather than monitoring weight.
Choice D rationale
Maintaining the client in high Fowler’s position is not necessary unless it helps with breathing. The priority is to keep the client comfortable.
