Correct Answer is D

Explanation

A. Distribution: Distribution refers to the process of a drug moving through the bloodstream to various tissues in the body, not leaving the body.

B. Absorption: Absorption is the process by which a drug enters the bloodstream from the site of administration. It is not related to the drug leaving the body.

C. Metabolism: Metabolism is the process by which the body breaks down a drug, typically in the liver, before it is excreted.

D. Excretion: Excretion is the correct term. It refers to the process by which drugs and their metabolites are eliminated from the body, primarily through the kidneys (urine) or the gastrointestinal tract (feces).

A. “You can receive the drug in a clinical trial.” B. “I understand your frustration, have you thought of traveling to another country for the medication.” C. “Have you considered using herbal remedies.” D. “The FDA requires drugs to be scientifically researched and this can take up to 8 years.”

Correct Answer is ["D"]

Explanation

A. “You can receive the drug in a clinical trial.” Clinical trials offer patients access to new treatments that are not yet widely available. This is a valid option for patients seeking treatments not yet approved by the FDA.

B. “I understand your frustration, have you thought of traveling to another country for the medication.” This is not an appropriate response. It doesn't provide information on the FDA approval process and may suggest that the patient should bypass U.S. regulations.

C. “Have you considered using herbal remedies.” While herbal remedies may offer some benefits, they are not a substitute for FDA-approved treatments, especially for a condition as serious as metastatic cancer.

D. “The FDA requires drugs to be scientifically researched and this can take up to 8 years.” This is accurate information. The FDA's approval process is rigorous and includes multiple phases of research to ensure a drug's safety and efficacy.
