A client asks what is meant by the statement "tolerance can occur when taking anxiolytics." The nurse understands that tolerance means which of the following?
Increased tolerance for medicinal side effects.
A different anxiolytic is necessary to treat symptoms.
Greater acceptance of the behaviors of other people when taking the medication.
Higher levels of medication are needed to achieve the expected effect.
The Correct Answer is D
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.

Correct Answer is A
Explanation
In pharmacodynamics, receptors play a crucial role in mediating the effects of medications ¹. Medications must bind with receptors to mimic or block the actions of the body's own regulatory molecules ¹. This binding can activate or inhibit the receptor, leading to a biological response ¹.
Option B is incorrect because activation of the receptor by the medication does not necessarily cause the cell to develop a new function.
Option C is incorrect because receptors do not start the process of metabolism of the medication by the liver.
Option D is incorrect because binding a medication to a receptor does not necessarily make the medication more selective to that type of receptor.
Correct Answer is B
Explanation
The sudden development of hives in a client taking phenytoin is most likely an allergic response to the medication. In this case, the medication should be stopped and the healthcare provider should be notified.
Option A is incorrect because a paradoxical reaction is not related to the development of hives.
Option C is incorrect because an idiosyncratic reaction is unpredictable and can disrupt the treatment plan.
Option D is incorrect because a hypersensitive response would require more than just reducing the dose; the medication should be stopped.
