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 C

Explanation

A. Elevate the head of the bed to a 45-degree angle:

Elevating the head of the bed can help improve airway patency and reduce the risk of airway obstruction in clients with OSA. While this intervention is important, applying the positive airway pressure device (CPAP or BiPAP) takes precedence due to its direct impact on maintaining airway patency and preventing respiratory compromise.

B. Lift and lock the side rails in place:

Ensuring the safety of the client by lifting and locking the side rails is important, but it does not directly address the client's OSA or the potential respiratory depression associated with opioid analgesic administration.

C. Apply the client's positive airway pressure device:

This is the most important intervention in this scenario. Clients with severe obstructive sleep apnea rely on positive airway pressure devices, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP), to maintain airway patency and prevent episodes of apnea during sleep. Applying the device before leaving the client alone ensures continuous support for effective breathing.

D. Remove dentures or other oral appliance:

While removing dentures or other oral appliances may be necessary for client comfort and safety, it is not directly related to managing OSA or preventing respiratory compromise associated with opioid analgesic administration.

A. Auscultate the bowel sounds in all four quadrants. B. Palpate the client's pedal pulse volume bilaterally. C. Determine the elasticity of the client's skin turgor. D. Observe the client's skin and mucous membranes.

Correct Answer is D

Explanation

A. Auscultate the bowel sounds in all four quadrants:

Auscultating bowel sounds is not directly relevant to nasopharyngeal suctioning. This assessment is more appropriate for evaluating gastrointestinal function and is not a priority during airway management procedures.

B. Palpate the client's pedal pulse volume bilaterally:

Palpating pedal pulse volume is not directly relevant to nasopharyngeal suctioning. This assessment is more appropriate for evaluating peripheral vascular perfusion and is not a priority during airway management procedures.

C. Determine the elasticity of the client's skin turgor:

Assessing skin turgor elasticity is not directly relevant to nasopharyngeal suctioning. This assessment is typically performed to evaluate hydration status and is not a priority during airway management procedures.

D. Observe the client's skin and mucous membranes:

This is the most appropriate assessment during nasopharyngeal suctioning. Observing the client's skin and mucous membranes helps monitor for signs of respiratory distress, such as cyanosis, pallor, or increased respiratory effort. It also allows the nurse to assess the effectiveness of airway clearance and potential complications related to the procedure.
