A nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?

A.

Finger

B.

Skin fold

C.

Toe

D.

Earlobe

Answer and Explanation

The Correct Answer is D

A. Applying the pulse oximeter to a finger may not be ideal due to edema, which can affect the accuracy of the reading.  

 

B. Using a skin fold is not a typical location for pulse oximetry and may not provide accurate readings.  

 

C. Applying the probe to a toe may be less effective if the toenails are thickened, potentially affecting blood flow to that area and the accuracy of the reading.  

 

D. The earlobe is a suitable alternative for measuring oxygen saturation, particularly in cases where peripheral sites (like fingers or toes) are compromised.

Correct Answer is B

Explanation

A. While a high-protein diet can support healing, it does not directly prevent the transmission of infection.

B. Performing hand hygiene before, during, and after direct contact with the client is crucial to prevent the transmission of pathogens and is a fundamental practice in infection control.

C. Positive-pressure airflow is used for clients who are immunocompromised to prevent them from contracting infections, not for clients with existing infections.

D. Changing bed linens daily can contribute to infection control but is not as effective as hand hygiene in preventing transmission.

Correct Answer is C

Explanation

A. Alcohol-based hand sanitizers are not effective against C. difficile spores; hand hygiene should be performed using soap and water to effectively remove the spores.

B. Testing for C. difficile typically involves stool samples, not blood specimens, making this option inappropriate for confirming the infection.

C. Placing the client on contact precautions is essential to prevent the spread of C. difficile, as it is highly contagious and can be transmitted via surfaces and direct contact.

D. A surgical mask is not necessary for clients with C. difficile unless they have respiratory symptoms; the primary concern is preventing contact transmission.
