Which statement about food and medication interactions is most accurate?
All medications are best absorbed on an empty stomach.
Client discomfort is the food and medication interaction of highest concern.
Foods can alter medication absorption and metabolism but not the action of the medication.
Some foods can inhibit cytochrome P450 (CYP) isoenzymes and alter medication metabolism.
The Correct Answer is D
Certain foods can interact with medications by inhibiting or inducing cytochrome P450 (CYP) enzymes, which play a crucial role in drug metabolism ¹. This can alter the way the body processes medications and affect their efficacy and safety ¹.
Option A is not correct because not all medications are best absorbed on an empty stomach. Some medications should be taken with food to improve absorption or reduce side effects ¹.
Option B is not correct because client discomfort is not the only concern when it comes to food and medication interactions.
Option C is not correct because foods can also alter the action of medications ¹.

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 D
Explanation
Flumazenil is a benzodiazepine antagonist that can be used as an antidote for lorazepam overdose ¹. It works by reversing the effects of benzodiazepines such as lorazepam ¹.
Option A is not correct because naloxone is an opioid antagonist and is not used to treat benzodiazepine overdose.
Option B is not correct because acetylcysteine is used to treat acetaminophen overdose and is not used to treat benzodiazepine overdose.
Option C is not correct because physostigmine is used to treat anticholinergic toxicity and is not used to treat benzodiazepine overdose.
