Final answer:
The incorrect statement about the vaginal ring, indicating a need for additional teaching, is that extra rings should be stored in the refrigerator. Vaginal rings should be stored at room temperature and used in a cycle of three weeks in, one week out.
Step-by-step explanation:
After teaching a woman who has chosen the vaginal ring as her method of contraception, the nurse determines that the client needs additional teaching when she makes the statement "I will store the extra rings in the refrigerator." This is an incorrect storage method for vaginal rings, as they should typically be stored at room temperature.
The vaginal ring, commonly known as NuvaRing, is a flexible contraceptive device that is inserted into the vagina. It should be kept in for three weeks and removed in the fourth week to allow for a menstrual period. A new ring is then inserted after the fourth week. The ring can indeed be left in place during intercourse, and it is typically inserted every month as part of the continuous cycle of contraception.
