A client is taking a drug that blocks a hormone's receptor site. What is the effect on the client's hormone response?
a. Greater hormone metabolism
b. Decreased hormone activity
c. Increased hormone activity

Hormones cause activity in the target tissues by binding with their specific cellular receptor sites, thereby changing the activity of the cell. When receptor sites are occupied by other substances that block hormone binding, the cell's response is the same as when the level of the hormone is decreased.
