A nurse in a health care provider’s office is reviewing lab results and notes a phenytoin level was drawn.
Which level would the nurse consider as therapeutic documentation?
9 mcg/mL
4 mcg/mL
24 mcg/mL
17 mcg/mL
The Correct Answer is D
According to web search results, the total phenytoin reference range for children and adults is **10-20 µg/mL**¹. This means that a level of 17 mcg/mL falls within the therapeutic range.
Option A is within the therapeutic range but is on the lower end.
Option B is below the therapeutic range.
Option C is above the therapeutic range and could be considered toxic.

Correct Answer is D
Explanation
Tolerance is a phenomenon that occurs when a person's body becomes accustomed to a medication over time. This means that the same dose of medication may no longer have the same effect as it did initially. In the case of anxiolytics, tolerance can mean that higher levels of medication are needed to achieve the expected effect. This is why
Option A refers to an increased ability to tolerate side effects, which is not the same as tolerance to the medication itself.
Option B suggests that a different medication is needed, but this is not necessarily the case when tolerance occurs.
Option C refers to greater acceptance of other people's behaviors, which is not related to tolerance to medication.
