Which of the following is a recommended action regarding the contraceptive sponge?

The recommended action regarding the contraceptive sponge is that it must be moistened with water prior to insertion. Moistening the sponge activates the spermicide contained within it, which enhances its effectiveness by creating a barrier and providing additional sperm-killing properties. This preparation step is crucial for ensuring the sponge functions as intended to prevent pregnancy.

In contrast, the sponge does not have a specific replacement guideline of every 6 months; instead, it can be used for up to 24 hours during which time it can be effective against multiple acts of intercourse, as long as it remains in place. It also does not require a prescription; it is available over-the-counter. The effectiveness window after insertion is significantly longer than the 12 hours mentioned, making proper understanding and preparation key to its successful use.
