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. Obtaining clarification from a client's healthcare power-of-attorney:

While clear communication is important in this scenario, SBAR may not be necessary as the nurse is seeking information rather than providing a detailed report or recommendation.

B. Completing discharge teaching to a client and family members:

SBAR may not be the most suitable format for discharge teaching, as it is primarily used for communication between healthcare providers regarding a patient's condition and care plan. Discharge teaching typically involves providing comprehensive instructions and information in a manner tailored to the needs of the client and family members.

C. Reporting a change in a client's condition to the healthcare provider:

This is the most appropriate scenario for using the SBAR format. When communicating a change in a client's condition to the healthcare provider, the SBAR framework allows the nurse to provide a concise summary of the situation, relevant background information, assessment findings, and recommendations for further action.

D. Offering therapeutic support and comfort to a grieving family:

SBAR communication is not suitable for offering therapeutic support and comfort to a grieving family. This interaction requires empathy, active listening, and emotional support rather than a structured communication format like SBAR.

A. Keeps a pair of gloves in uniform pocket. B. Uses sterile gloves when handling body fluids. C. Dons sterile gloves when caring for clients with HIV. D. Puts on new gloves when entering a client's room.

Correct Answer is D

Explanation

A. Keeping a pair of gloves in a uniform pocket:

While it may be convenient to carry gloves, this action alone does not necessarily indicate an understanding of appropriate gloving procedures. Simply having gloves readily available does not ensure that they are used correctly or in accordance with infection control protocols.

B. Using sterile gloves when handling body fluids:

This action indicates an understanding of the need for sterile gloves when handling potentially infectious body fluids. However, it's important to note that not all situations require sterile gloves, and the use of sterile gloves should be based on the specific clinical context and infection control guidelines.

C. Donning sterile gloves when caring for clients with HIV:

While wearing gloves when caring for clients with HIV is important for infection control, not all situations require sterile gloves. The use of sterile gloves should be based on the specific clinical context and infection control guidelines.

D. Putting on new gloves when entering a client's room:

This action demonstrates an understanding of the importance of donning clean gloves when entering a client's room to prevent the spread of infection. It indicates adherence to standard precautions and proper infection control practices, making it the most appropriate choice.
