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. Eating apples and black-eyed peas is not typically associated with impaired bowel
elimination. In fact, these foods are often considered high in fiber, which can promote regular bowel movements.
B. Drinking an adequate amount of water daily is generally beneficial for bowel health and can help prevent constipation.
C. Taking opioid pain medication is a significant risk factor for impaired bowel elimination.
Opioids are known to slow down bowel motility and can lead to constipation.
D. Drinking coffee in moderation may have a mild laxative effect for some individuals and is not necessarily indicative of impaired bowel elimination.
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"D"}
Explanation
At 1000, when the nurse enters the client's room and the client is experiencing an aura followed by generalized jerking contractions of arms and legs, the first action the nurse should take is to ensure the client's safety. This includes removing any potential hazards from the immediate vicinity, such as pillows that could obstruct the airway or cause suffocation.
The next critical action is to turn the client to their side, which helps maintain an open airway, allows for any secretions to drain, and reduces the risk of aspiration should vomiting occur. These steps are vital in managing a seizure and are part of the standard care procedures to protect the client during and after a seizure episode.
