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.

Answer and Explanation

The Correct Answer is B

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 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 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

Giving the client a hug and saying, “It is okay to cry when you are sad,” may be comforting, but it may also be seen as intrusive and not respecting the client’s personal space. Physical touch should be used cautiously and only when the nurse is certain that it is welcome and appropriate. Additionally, this response does not encourage the client to express their feelings or provide an opportunity for the nurse to understand the underlying cause of the client’s distress.

Choice B rationale

Saying, “I am sorry to disturb you at a difficult time. This can wait until later,” acknowledges the client’s distress but does not offer immediate support or an opportunity for the client to express their feelings. It may also give the impression that the nurse is not available to provide emotional support when needed.

Choice C rationale

While touching the client’s forearm, asking, “Would you like to talk about it?” is the best response as it shows empathy and offers the client an opportunity to express their feelings. This response respects the client’s personal space while also providing a gentle touch that can be comforting. It opens the door for communication and allows the nurse to provide emotional support and address any concerns the client may have.

Choice D rationale

Saying, “This is a bad time. I can see you are upset. I can come back later,” acknowledges the client’s distress but does not offer immediate support or an opportunity for the client to express their feelings. It may also give the impression that the nurse is not available to provide emotional support when needed.

A. After each instruction, ask if the client understands. B. Have an interpreter repeat the wound care instructions. C. Have the client demonstrate prescribed wound care. D. Provide written instructions in the client’s native language. E. Answer and explanation

Correct Answer is C

Explanation

Choice A rationale

Asking the client if they understand after each instruction may not be effective if the client is not comfortable expressing confusion or misunderstanding. It does not allow for direct observation of the client’s ability to perform the necessary tasks.

Choice B rationale

Having an interpreter repeat the wound care instructions may be helpful, but it still does not allow for direct observation of the client’s ability to perform the necessary tasks.

Choice C rationale

Having the client demonstrate prescribed wound care is the best way to evaluate the client’s understanding of self-care at home. This allows the nurse to directly observe the client’s ability to perform the necessary tasks and provide feedback and clarification as needed.

Choice D rationale

Providing written instructions in the client’s native language may be helpful, but it does not allow the nurse to directly evaluate the client’s understanding
