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
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.
Correct Answer is B
Explanation
Choice A rationale
Inserting a rectal tube at specified intervals is not a standard practice for bowel training regimens. This intervention is typically reserved for specific medical conditions and is not recommended for routine management of chronic fecal incontinence.
Choice B rationale
Assisting the client to a bedside commode 30 minutes after meals leverages the natural gastrocolic reflex, which stimulates bowel movements after eating. This intervention helps establish a regular bowel routine and is a key component of bowel retraining programs.
Choice C rationale
Encouraging the use of incontinence briefs does not address the underlying issue of bowel incontinence and may not help in establishing a regular bowel routine. This intervention is more focused on managing the symptoms rather than treating the condition.
Choice D rationale
Administering a glycerin suppository 15 minutes after meals can stimulate bowel movements, but it is not the first-line intervention for establishing a bowel training regimen. This approach may be used as an adjunct to other bowel retraining techniques.
