Nursing Elites

1. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

2. What action should be taken when adding sterile liquids to a sterile field?

• A. Use an expired sterile liquid if the bottle is sealed and unopened.
• B. Consider the sterile field contaminated if it becomes wet during the procedure.
• C. Remove the container cap and place it with the inside facing up on the sterile field.
• D. Hold the container low and pour the solution into a receptacle at the front of the sterile field.

Correct answer: B

Rationale: If a sterile field becomes wet or damp during a procedure, it is considered contaminated as moisture can allow organisms to wick from the surface and compromise the sterility of the field. It is essential to maintain the integrity of the sterile field to prevent infections and ensure patient safety.

3. While changing a client’s post-operative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given a positive MRSA result, what is the most important action for the nurse to take?

• A. Force oral fluids
• B. Request a nutrition consult
• C. Initiate contact precautions
• D. Limit visitors to immediate family only

Correct answer: C

Rationale: Initiating contact precautions is crucial in this situation to prevent the spread of MRSA infection. MRSA is a highly contagious bacterium that can spread through direct contact with an infected wound or by touching contaminated surfaces. By implementing contact precautions, the nurse can help contain the infection and protect other patients, healthcare workers, and visitors from being exposed to MRSA.

4. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

5. A client in the early stages of Alzheimer’s disease is very anxious and frequently asks about her deceased parents. Which intervention should the nurse implement to reduce the client’s anxiety?

• A. Remind the client that her parents have passed away
• B. Ask the client about her favorite memories with her parents
• C. Engage the client in an activity to distract her from thinking about her parents
• D. Reorient the client to the present reality and surroundings

Correct answer: C

Rationale: Engaging the client in an activity to distract her from thinking about her deceased parents is the most appropriate intervention to reduce anxiety. This approach helps shift the focus away from distressing thoughts and can provide comfort and a sense of calm to the client.
