A nurse is planning to obtain a client's oxygen saturation. Which of the following might influence the result of this test?
The client is wearing nail polish.
The client has an elevated hemoglobin level.
The client has a fever.
The client is wearing a ring.
The Correct Answer is A
A. Nail polish can interfere with the accuracy of pulse oximetry readings by absorbing or
reflecting light, leading to falsely low oxygen saturation readings. It's essential to remove nail polish or acrylic nails from the finger used for pulse oximetry to obtain accurate results.
B. While an elevated hemoglobin level may affect the oxygen-carrying capacity of the blood, it does not directly influence the accuracy of pulse oximetry readings.
C. Fever may affect oxygen saturation levels indirectly by increasing metabolic demand or
respiratory rate, but it does not directly interfere with the accuracy of pulse oximetry readings.
D. Wearing a ring does not typically interfere with pulse oximetry readings unless the ring is very tight and impairs blood flow to the finger. However, nail polish is a more significant
concern for accurate readings.

Correct Answer is C
Explanation
A. The stoma bleeds lightly when touched: Light bleeding is common postoperatively and may not be concerning unless it's excessive or persistent.
B. The stoma is draining a small amount of liquid stool: This is a normal finding following colostomy placement and is expected in the early postoperative period.
C. The stoma appears dark in color: This may indicate compromised blood supply to the stoma and requires immediate evaluation by the provider.
D. The stoma protrudes slightly from the abdomen: This is a normal finding post-colostomy and does not typically require immediate intervention.
Correct Answer is B
Explanation
A. Dismissing the employee's concerns by stating there has been too much complaining is not empathetic or supportive.
B. This response acknowledges the employee's feelings and opens the door for further discussion about their concerns, allowing the charge nurse to address them.
C. Suggesting filing a formal complaint with Human Resources may escalate the situation unnecessarily and should not be the initial response.
D. While expressing optimism about the situation may be well-intentioned, it does not address the employee's concerns or offer support.
