Normal range for oxygen saturation via pulse oximeter is?
80-100%
93-100%
90-100%
95-100%
The Correct Answer is D
A: An oxygen saturation range of 80-100% is incorrect. Saturation levels below 90% are considered low and may indicate hypoxemia, requiring medical attention.
B: An oxygen saturation range of 93-100% is generally acceptable, but the ideal range is slightly higher to ensure adequate oxygenation.
C: An oxygen saturation range of 90-100% includes levels that are borderline low. While 90% is often used as a threshold for concern, the optimal range is higher.
D: An oxygen saturation range of 95-100% is considered normal and indicates adequate oxygenation of the blood. This range ensures that tissues receive sufficient oxygen to function properly.

Explanation
A: Degenerative joint changes can affect mobility and overall health but do not directly contribute to aspiration pneumonia.
B: Decreased gastric secretions can affect digestion but are not a primary factor in the development of aspiration pneumonia.
C: A decreased sense of smell can affect appetite and food intake but does not directly lead to aspiration pneumonia.
D: A diminished cough reflex is a significant age-related change that can contribute to the development of aspiration pneumonia. The cough reflex helps clear the airway of food, liquid, and other foreign materials. When this reflex is diminished, the risk of aspiration and subsequent pneumonia increases.
Correct Answer is A
Explanation
A: The nurse should check the medication order again to ensure that the correct medication is being administered. This response addresses the client’s concern and ensures patient safety.
B: Telling the client that this is the medication their doctor wants them to take does not address the client’s concern about the color difference and may not ensure the correct medication is given.
C: While it is true that the same medication can come in different colors, this response does not verify the accuracy of the medication being administered.
D: Explaining the purpose of the medication is important, but it does not address the immediate concern about the color difference and the need to verify the medication.
