Correct Answer: B

Rationale: The correct answer is B: Malignant cells contain proteins called tumor-specific antigens. Tumor-specific antigens are unique to cancer cells and are not found in normal cells. This characteristic distinguishes cancer cells from normal cells and is important in cancer detection and treatment. A: Malignant cells do not necessarily contain more fibronectin than normal body cells. Fibronectin is a glycoprotein found in the extracellular matrix and is not a defining characteristic of cancer cells. C: Chromosomes in cancer cells are actually more prone to instability and mutations compared to normal cells, making them less durable and stable. D: The nuclei of cancer cells can vary in size and shape, with irregularities often seen, rather than being unusually large and regularly shaped.

Correct Answer: A

Rationale: The correct answer is A: Cottage cheese-like discharge. Candida albicans is a common cause of vulvovaginal candidiasis, characterized by itching and cottage cheese-like discharge. This type of discharge is specific to a yeast infection. Yellow-green discharge (choice B) is indicative of trichomoniasis, gray-white discharge (choice C) is seen in bacterial vaginosis, and watery discharge with a fishy odor (choice D) is characteristic of bacterial vaginosis or trichomoniasis. Therefore, the presence of cottage cheese-like discharge is a key indicator of a Candida albicans infection.

Correct Answer: D

Rationale: The correct answer is D because being aware of patients' medication regimens allows nurses to identify and monitor ototoxic medications that can cause hearing loss. By collaborating with other professionals, nurses can adjust medications or recommend alternative treatments to prevent or minimize ototoxicity. This proactive approach directly targets the root cause of potential hearing loss. A: Understanding types of hearing loss is important but does not directly prevent ototoxicity. B: Educating about age-related changes in hearing does not address ototoxicity prevention. C: Educating about noise exposure risks is important for overall hearing health but does not specifically prevent ototoxicity.

Correct Answer: C

Rationale: The correct answer is C: Research has shown that exercising at least 30 minutes every day can reduce your chance of breast cancer. Rationale: 1. Regular exercise helps maintain a healthy weight, which is important in reducing the risk of breast cancer. 2. Physical activity can help regulate hormone levels, such as estrogen, which can affect breast cancer risk. 3. Exercise boosts the immune system and reduces inflammation, both of which play a role in cancer prevention. Summary: A: Eating a healthy diet is important, but it alone cannot provide all the protection needed against breast cancer. B: Tamoxifen may be recommended in some cases, but it is not the primary preventive measure for everyone. D: While genetic predisposition increases risk, lifestyle choices like exercise can still play a significant role in reducing the risk of breast cancer.

Correct Answer: A

Rationale: The correct answer is A: Provide emotional support to the patient and her family. This is the priority as the patient has received devastating news and needs immediate support. Emotional support can help the patient cope with the diagnosis, express feelings, and make decisions. B: Implementing distraction techniques may not address the patient's emotional needs in this critical situation. C: Offering to inform the family of the diagnosis is important but not the priority at this moment. D: Teaching about maintaining a positive attitude may not be appropriate as the patient is facing a terminal illness.
