The client receiving chemotherapy asked the nurse how most anticancer drugs kill cancer cells. The nurse's response would include that the mechanism of action works by:
a. affecting DNA synthesis or function
b. damaging the plasma membrane and making the cell vulnerable to osmotic pressure
c. inhibiting cell-wall synthesis during active multiplication
d. inhibiting dependent RNA polymerase in susceptible cells, blocking protein synthesis
A
Chemotherapy involves the use of antineoplastic drugs to cure, prevent, or relieve cancer symptoms. These drugs inhibit the growth and reproduction of malignant cells by affecting DNA synthesis or function; they vary in how they affect the cell cycle and are classified as either cell-cycle specific (most effective against rapidly growing tumors) or cell-cycle nonspecific (used for large tumors with fewer actively dividing cells).
