Which statement, from a participant attending the class on AIDS prevention, indicates an understanding on how to reduce transmission of HIV?

Correct Answer: B

Rationale: The correct answer is B because implementing a needle exchange program is an effective way to reduce transmission of HIV among intravenous drug users. By providing clean needles in exchange for dirty needles, the risk of sharing contaminated needles and spreading the virus is significantly reduced. This approach also helps prevent the transmission of other bloodborne diseases, such as Hepatitis C. The other statements do not demonstrate an understanding of how to reduce HIV transmission - for example, encouraging breastfeeding for HIV-positive mothers can transmit the virus to the baby, birth control pills do not protect against HIV, and natural skin condoms do not offer the same level of protection as latex condoms.

Correct Answer: B

Rationale: Providing a solution of hydrogen peroxide and water for use as a mouth rinse is most likely to decrease the pain of stomatitis. Stomatitis is inflammation of the oral mucous membranes and can be quite painful for oncology clients undergoing chemotherapy. Using a solution of hydrogen peroxide and water as a mouth rinse can help reduce the risk of infection and promote healing of the mucous membranes, thereby decreasing the pain associated with stomatitis. This intervention helps to maintain oral hygiene and prevent further complications, making it an effective way to manage the client's symptoms while undergoing chemotherapy. It is important to note that discontinuing chemotherapy would not be a recommended intervention as it is the primary treatment for the client's cancer. Monitoring platelet and leukocyte counts and checking for signs and symptoms of stomatitis are important aspects of care, but providing a mouth rinse would directly address the pain and discomfort experienced by the client.

Correct Answer: C

Rationale: The assessment finding that strongly suggests that the client's lump is cancerous is a non-mobile mass with irregular edges delineated. Generally, cancerous breast lumps tend to have irregular shapes/edges and lack mobility. This finding is concerning for malignancy because it indicates that the lump is fixed in place and possibly invading nearby tissues, which are characteristics often associated with cancerous tumors. It's essential for the client to undergo further diagnostic tests, such as a biopsy, to confirm the presence of cancer and establish a proper treatment plan.

Correct Answer: B

Rationale: A fixed nodular mass with dimpling of the overlying skin is the finding that most strongly suggests breast cancer. This presentation is concerning for an invasive carcinoma that has invaded into the surrounding tissues, leading to the dimpling of the skin. Breast cancer typically presents as a painless, hard, irregularly shaped, non-mobile mass. Dimpling of the skin overlying the mass is a sign of advanced disease and is often associated with a poor prognosis. Therefore, this finding should raise suspicion for breast cancer and prompt further evaluation and workup.

Correct Answer: B

Rationale: One of the major risk factors for ovarian cancer is nulliparity, which means never having been pregnant. This is because pregnancy and childbirth have a protective effect against ovarian cancer. Women who have never been pregnant are at a higher risk of developing ovarian cancer compared to women who have had children. Age is also a significant risk factor for ovarian cancer, with the risk increasing as women get older. Therefore, the 45-year old woman who has never been pregnant has the highest risk of ovarian cancer among the given clients.
