A nurse is providing teaching to a group of women about risk factors for ovarian cancer. Which of the following risk factors should the nurse include? (Select all that apply.)

Choice A rationale:

Nulliparity (never having given birth) is a known risk factor for ovarian cancer. Women who have never had children have a higher risk compared to those who have. This is believed to be associated with the number of ovulatory cycles a woman experiences throughout her lifetime.

Choice B rationale:

History of breastfeeding does not have a direct link to ovarian cancer risk. In fact, breastfeeding is associated with a reduced risk of both breast and ovarian cancer due to hormonal changes that occur during lactation.

Choice C rationale:

Previous use of oral contraceptives is associated with a decreased risk of ovarian cancer. Women who have used birth control pills have a lower risk compared to those who have never used them. The protective effect is believed to be due to the suppression of ovulation.

Choice D rationale:

History of breast cancer is not a risk factor for ovarian cancer. Although both cancers are related to the reproductive system, they have distinct risk factors and characteristics.

Choice E rationale:

Hormone replacement therapy (HRT) is a potential risk factor for ovarian cancer, especially long-term use. The hormones used in HRT can affect hormone levels and may increase the risk of ovarian cancer.

Choice A reason:

Requesting a prescription for PRN aspirin is incorrect because aspirin is an antiplatelet agent and should not be combined with heparin without specific medical advice due to the increased risk of bleeding.

Choice B reason:

Massaging the injection site is not recommended as it can cause trauma to the tissue and increase the risk of bleeding, which is especially concerning in a patient with deep-vein thrombosis.

Choice C reason:

Instructing the client that they cannot breastfeed while receiving heparin is incorrect. Heparin does not pass into breast milk in significant amounts and is considered safe for use while breastfeeding.

Choice D reason:

Administer the injection in the client's abdomen. Heparin is typically administered subcutaneously in the abdomen to ensure proper absorption and minimize discomfort. Because it is an area with large amounts of subcutaneous fat
