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","B","D"]
Explanation
Choice A rationale
Determine client’s subjective measure of pain using a numerical pain scale. Assessing the client’s pain using a numerical pain scale allows the nurse to understand the client’s perception of their pain and to monitor changes over time. This is a crucial step in managing chronic pain as it provides a baseline for evaluating the effectiveness of interventions.
Choice B rationale
Implement a 24-hour schedule of routine administration of prescribed analgesic. Chronic pain management often requires a consistent and routine administration of analgesics to maintain a stable level of pain control. This approach helps to prevent the peaks and troughs of pain that can occur with as-needed dosing.
Choice C rationale
Assist the client to ambulate as much as possible during waking hours. While ambulation can be beneficial for some clients, it may not be appropriate for all clients with chronic pain, especially if the pain is severe or if ambulation exacerbates the pain. Therefore, this intervention should be individualized based on the client’s condition.
Choice D rationale
Provide comfort measures such as topical warm application and tactile massage. Non- pharmacological interventions such as warm applications and massage can help to alleviate pain and improve comfort. These measures can be used in conjunction with pharmacological treatments to provide a more comprehensive approach to pain management.
Choice E rationale
Encourage increased fluid intake and measure urinary output every 8 hours. While maintaining adequate hydration is important, this intervention is not directly related to the management of chronic pain. It may be more relevant for clients with other conditions such as renal issues.
Correct Answer is D
Explanation
Choice A rationale
Administering PRN oral pain medication without further assessment may not be appropriate, as the client’s pain needs must be fully evaluated before intervening with medication. Pain medication should be administered based on an accurate assessment rather than solely on nonverbal cues.
Choice B rationale
Reviewing the pain medications prescribed is important, particularly if the client is exhibiting signs of uncontrolled pain. However, this intervention should be secondary to further assessment of the client’s current pain status.
Choice C rationale
Administering PRN oral pain medication without further assessment may not be appropriate, as the client’s pain needs must be fully evaluated before intervening with medication. Pain medication should be administered based on an accurate assessment rather than solely on nonverbal cues.
Choice D rationale
Asking the client what is causing the grimacing is the correct intervention to implement first. Nonverbal cues, such as grimacing, can indicate the presence of pain, even if the client denies it verbally. By closely monitoring the client’s nonverbal behavior, the nurse can gather additional information about the client’s pain experience and make appropriate interventions based on a comprehensive assessment.
