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?

Blood pressure is 142/88 mm Hg.

Radial pulse volume is 3+.

2+ edema of fingers and hands.

Capillary refill time is 2 seconds.

Answer and Explanation

The Correct Answer is C

A. Blood pressure is 142/88 mm Hg:

While elevated blood pressure may have implications for cardiovascular health, it is not directly related to oxygen saturation levels measured by a pulse oximeter.

B. Radial pulse volume is 3+:

A strong radial pulse volume suggests adequate peripheral perfusion, which would not typically contribute to a low oxygen saturation reading.

C. 2+ edema of fingers and hands:

Edema of the fingers and hands can impair the transmission of light through tissues, which may interfere with the accuracy of oxygen saturation readings obtained from a pulse oximeter. Edematous tissues may absorb light and lead to falsely low readings.

D. Capillary refill time is 2 seconds:

Normal capillary refill time indicates adequate peripheral circulation, which would not typically contribute to a low oxygen saturation reading.

Correct Answer is A

Explanation

A. When the client voided following catheter removal:

This information is crucial because it indicates the return of the client's ability to urinate after catheter removal. It helps assess urinary function and determines if the client is experiencing any urinary retention issues, which could potentially lead to complications such as urinary tract infections or bladder distention.

B. Color of the urine during catheter removal:

While the color of the urine during catheter removal may provide some insight into the client's urinary condition, it is not as critical as knowing when the client voided after catheter removal to assess urinary function.

C. Time of the last dose of IV antibiotic administration:

While the timing of the last dose of IV antibiotic administration is important for managing the client's urinary tract infection, it is not as immediately relevant as knowing when the client voided after catheter removal to assess urinary function.

D. Intake and output reports for the previous shift:

Intake and output reports are important for assessing fluid balance and renal function, but knowing when the client voided after catheter removal takes precedence as it directly assesses urinary function and the need for further intervention.

A. Positive external places. B. Emotional reflection. C. Motivational phrases. D. Tranquil sounds.

Correct Answer is A

Explanation

A. Positive external places:

Guided imagery typically involves directing the client to visualize calming and peaceful external environments, such as a beach, forest, or other positive, serene places. This technique helps divert the client's attention away from pain and promotes relaxation.

B. Emotional reflection:

Emotional reflection may be part of the guided imagery process, especially if it helps the client process and cope with their emotions related to chronic pain. However, the primary focus of guided imagery is typically on visualization techniques rather than emotional reflection alone.

C. Motivational phrases:

Motivational phrases can be helpful in some relaxation techniques, but in guided imagery for chronic pain management, the emphasis is usually on visualizing soothing images or scenarios rather than repeating motivational phrases.

D. Tranquil sounds:

Tranquil sounds may be part of a relaxation strategy, but guided imagery specifically involves visualizing calming scenes, not just focusing on sounds.
