Which statement by a client indicates an understanding of contraceptive options involving latex condoms?

The statement indicating an understanding of contraceptive options involving latex condoms is accurate because it correctly identifies that water-soluble lubricants are safe to use with latex condoms. These types of lubricants do not deteriorate the latex material, thus maintaining the integrity of the condom and ensuring effective contraception and protection against sexually transmitted infections.

In contrast, the suggestion to use oils as lubricants with latex condoms is flawed since oil-based products can weaken latex, increasing the risk of breakage. The concept of reusing latex condoms is incorrect as they are designed for single use to guarantee their effectiveness and safety. Finally, not using any lubricant with latex condoms can lead to increased friction, which may cause the condom to break or slip off, negating their protective benefits. Therefore, the option that states the use of a water-soluble lubricant demonstrates a proper understanding of condom usage and safety.
