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 C
Explanation
Benzodiazepines are medications that work in the central nervous system and are used for a variety of medical conditions such as anxiety, seizures, and alcohol withdrawal ². They work by blocking excessive activity of nerves in the brain and other areas in the central nervous system ². While benzodiazepines can be effective in treating these conditions, they are not a cure and should be used as part of a comprehensive treatment plan that may include counseling or other forms of therapy ¹.
Option A is not correct because benzodiazepines do not require frequent blood counts to avoid adverse effects.
Option B is not correct because the decision to stop a medication should be made by a healthcare provider based on an individual's response to treatment.
Option D is not correct because benzodiazepines are not intended for long-term use and should be used for the shortest possible time to achieve therapeutic goals ².
Correct Answer is C
Explanation
A half-life is the time it takes for the concentration of a drug in the body to decrease by half. In this case, the medication has an 8-hour half-life, so after 8 hours, the concentration of the medication in the client's body would be reduced to 400mg (half of the initial dose of 800mg). After another 8 hours (16 hours total), the concentration would be reduced to 200mg. After another 8 hours (24 hours total), the concentration would be reduced to 100mg.
