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 ["B","C","E"]

Explanation

A. Use standard precautions and wear a mask.

While standard precautions should always be followed to prevent the spread of infection, wearing a mask is not specifically indicated for MRSA unless there is a risk of respiratory transmission. Contact precautions are more appropriate for MRSA.

B. Institute contact precautions for staff and visitors.

Contact precautions are necessary to prevent the spread of MRSA, a highly contagious bacteria. This involves using gloves and gowns when entering the client's room to prevent transmission of the bacteria to others.

C. Send wound drainage for culture and sensitivity.

Culturing the wound drainage helps identify the specific bacteria causing the infection and determines the most effective antibiotics for treatment (sensitivity testing).

D. Explain the purpose of a low bacteria diet.

A low bacteria diet is not typically indicated for managing MRSA infections. Instead, the focus should be on wound care, antibiotic therapy, and infection control measures to address the MRSA infection.

E. Monitor the client's white blood cell count.

Monitoring the white blood cell count helps assess the client's immune response and the severity of the infection. Elevated white blood cell counts may indicate an active infection and the need for further intervention.

A. "This unit has a policy against staff harassment." B. "It is important to dress the right arm first." C. "Dressing must be a frustrating experience for you." D. "We will give you a class on dressing tomorrow." E. Monitor the client's white blood cell count.

Correct Answer is C

Explanation

A. "This unit has a policy against staff harassment."

This response addresses the client's cursing behavior directly and attempts to establish boundaries by referring to the unit's policy. However, it may come across as confrontational and could potentially escalate the situation further. While it's important to address inappropriate behavior, in this case, responding with empathy and understanding might be more effective in de-escalating the situation and building rapport.

B. "It is important to dress the right arm first."

This response focuses on the physical aspect of dressing and does not acknowledge the client's frustration or emotional state. While it provides guidance on dressing technique, it does not address the underlying issue of the client's struggle or emotional distress. In this situation, addressing the client's emotional needs and frustrations may be more beneficial.

C. "Dressing must be a frustrating experience for you."

This response demonstrates empathy and understanding towards the client's frustration. It acknowledges the client's emotional state and validates their feelings, which can help build rapport and trust. By expressing empathy, the nurse can create a supportive environment and open the door for effective communication with the client.

D. "We will give you a class on dressing tomorrow."

This response offers a solution for the future but does not address the client's immediate frustration or emotional distress. While education on dressing techniques may be helpful in the long run, it does not address the client's current struggle or provide support in the moment. In this situation, addressing the client's emotional needs and frustrations should take priority.
