An older adult woman comes to the clinic because of vaginal bleeding. The healthcare provider finds a vaginal tear, which the client reports is likely to have occurred during unprotected sexual intercourse. Which content is most important for the nurse to include in this client's teaching plan?

In postmenopausal women, declining estrogen levels lead to atrophic vaginitis, characterized by thinning, dryness, and reduced elasticity of vaginal tissues. These changes make the vaginal mucosa more susceptible to tearing during sexual intercourse. The most important and directly relevant teaching for this client is the use of vaginal lubricants, which address the underlying physiological cause of the tear by reducing friction and mechanical trauma during intercourse. This intervention is practical, safe, and directly preventive of recurrence. While safe sex education regarding methods to prevent sexually transmitted infections is valuable and should be incorporated into a broader teaching plan, it does not directly address the vaginal tearing that occurred. Discussing intercourse positions may have marginal benefit but does not correct the primary problem of tissue fragility due to dryness. Providing information about alternative ways to express sexuality implies the client should avoid intercourse altogether, which is unnecessarily restrictive and does not respect the client's autonomy or sexual health. The physiological etiology — vaginal atrophy and dryness — makes lubricant education the most targeted and important teaching priority for preventing future injury.
