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.

elimination. In fact, these foods are often considered high in fiber, which can promote regular bowel movements.

C. Taking opioid pain medication is a significant risk factor for impaired bowel elimination.

Correct Answer is D
Explanation
A. Clients with expressive aphasia have difficulty expressing themselves verbally but can often understand spoken language. It's important for the nurse to provide the teaching without
expecting a verbal response from the client. The client may still benefit from receiving information even if they cannot verbally respond.
B. Speaking loudly is not helpful for clients with expressive aphasia and may increase confusion or frustration. The nurse should speak clearly and at a normal volume.
C. Facial gestures can aid in communication for clients with expressive aphasia by providing additional cues. The nurse should use facial expressions to enhance communication.
D.Clients with expressive aphasia have difficulty expressing themselves verbally. Assessing the client's ability to use alternative communication methods, such as a communication board, can help facilitate effective communication and understanding of the teaching.
