A 58-year-old man is going to have chemotherapy for lung cancer. He asks the nurse how the chemotherapeutic drugs will work.The most accurate explanation the nurse can give is which of the following?

"The molecular structure of the DNA is altered."

"Cancer cells are susceptible to drug toxins."

"Chemotherapy encourages cancer cells to divide."

"Chemotherapy affects all rapidly dividing cells."

Answer and Explanation

The Correct Answer is D

Chemotherapy is a treatment modality used to target and destroy rapidly dividing cells, including cancer cells. It works by interfering with the cell division process, which is a characteristic of cancer cells. However, it is important to note that chemotherapy drugs can also affect normal, healthy cells in the body that undergo rapid division, such as cells in the bone marrow, hair follicles, and gastrointestinal lining. This is why chemotherapy can be associated with side effects like bone marrow suppression, hair loss, and gastrointestinal disturbances. While the molecular structure of DNA can be altered by certain chemotherapeutic drugs, this explanation is not comprehensive enough to encompass the overall mechanism of action of chemotherapy.

The statement that "cancer cells are susceptible to drug toxins" is partially true, as cancer cells are generally more vulnerable to the cytotoxic effects of chemotherapy drugs compared to normal cells.

Chemotherapy aims to disrupt the division and growth of cancer cells rather than promoting their division.

Correct Answer is D

Explanation

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of medications commonly used to relieve pain, reduce inflammation, and lower fever. They work by inhibiting the production of prostaglandins, which are substances in the body that play a role in pain and inflammation. Celecoxib specifically belongs to the subclass of NSAIDs known as selective COX-2 inhibitors, which target the enzyme cyclooxygenase-2 (COX-2). By selectively inhibiting COX-2, celecoxib helps to reduce inflammation and pain while potentially minimizing the gastrointestinal side effects associated with traditional non-selective NSAIDs.
