What statement indicates a client’s understanding of diaphragm use for contraception?

The statement indicating the client's understanding of diaphragm use for contraception is that the client will place 2 teaspoons of spermicide on the inside of the diaphragm before inserting it. This is correct because the diaphragm must be used in conjunction with spermicide to maximize its effectiveness as a contraceptive method. The spermicide acts as a chemical barrier to prevent sperm from reaching the egg, increasing the overall efficacy of the diaphragm in preventing pregnancy. Proper application of spermicide is essential, as it should be applied to the diaphragm prior to insertion to ensure it is activated and effective during intercourse.

Using the diaphragm correctly involves understanding both its insertion and the accompanying use of spermicide, as they work together to create an effective barrier against sperm.
