A community health nurse is preparing a poster for an educational session for a group of women with whom she will be discussing the risk factors for breast cancer. Which factors increase the risk for breast cancer and should be listed on the poster? Select all that apply.
Family history of breast cancer.
Multiparity.
Exposure of the chest to high dose radiation.
Previous cancer of breast, uterus, or ovaries.
Correct Answer : A,C,D
Choice A rationale
A family history of breast cancer is a significant risk factor because genetic mutations, such as BRCA1 and BRCA2, can be inherited and increase the likelihood of developing breast cancer.
Choice B rationale
Multiparity (having multiple pregnancies) is generally considered to reduce the risk of breast cancer. This is because pregnancy and breastfeeding lower the number of menstrual cycles a woman has, reducing her lifetime exposure to estrogen.
Choice C rationale
Exposure of the chest to high-dose radiation, especially during childhood or young adulthood, increases the risk of breast cancer. Radiation can cause mutations in breast cells, leading to cancer.
Choice D rationale
Previous cancer of the breast, uterus, or ovaries increases the risk of developing breast cancer. This is due to shared risk factors and the possibility of metastasis or recurrence.

Correct Answer is C
Explanation
Choice A rationale
Headaches and blurred vision are not specific to stage I Lyme disease. These symptoms can occur in many other conditions and are not the primary indicators of early Lyme disease.
Choice B rationale
Tremors and weakness are not typical early signs of Lyme disease. These symptoms are more associated with neurological involvement, which occurs in later stages of the disease.
Choice C rationale
Rash symptoms, specifically erythema migrans (a bull’s-eye rash), are the hallmark of stage I Lyme disease. This rash appears at the site of the tick bite and is a key diagnostic feature.
Choice D rationale
Painful joints are more commonly seen in later stages of Lyme disease when the infection has spread and caused more systemic involvement.
