Correct Answer: A

Rationale: The correct answer is A: Lumpectomy and radiation. For a small, well-defined nodule in the breast, lumpectomy (removal of the lump) followed by radiation therapy is usually the treatment of choice for early-stage breast cancer. This approach aims to preserve the breast while ensuring effective treatment. Partial mastectomy (B) involves removing a larger portion of the breast tissue and is not typically necessary for a small, well-defined nodule. Chemotherapy (C) is generally used for more advanced stages of breast cancer or when the cancer has spread beyond the breast. Total mastectomy (D) is considered when the cancer is more extensive or in cases where lumpectomy is not feasible.

Correct Answer: B

Rationale: The correct answer is B because assessing and promoting the patient's coping skills is essential in addressing the psychosocial needs of a patient with macular degeneration. By understanding how the patient is coping with the vision loss, the nurse can tailor interventions to support the patient effectively. This approach acknowledges the patient's emotional responses and helps them navigate the challenges associated with the condition. Choice A is incorrect as solely focusing on other senses may not address the psychological impact of vision loss. Choice C is incorrect as it dismisses the significant lifestyle changes the patient may experience. Choice D is incorrect as promoting hope for recovery may not be realistic in the case of irreversible conditions like macular degeneration.

Correct Answer: A

Rationale: The correct answer is A because providing care that fits the patient's valued life patterns and set of meanings demonstrates cultural congruence. This approach acknowledges and respects the patient's cultural background, beliefs, and preferences. It promotes patient-centered care and enhances communication and trust between the nurse and the patient. Choice B is incorrect because care based on predetermined criteria may not align with the patient's individual cultural needs. Choice C is incorrect as it does not prioritize the patient's values and preferences. Choice D is incorrect because providing care based solely on the values of the professional health care system may not consider the cultural diversity of the patient population.

Correct Answer: A

Rationale: The correct answer is A because it addresses the key issue of perception of risk among older adults. Many older adults may not perceive themselves as being at risk for HIV infection due to misconceptions or lack of awareness. This principle guides the nurse to tailor educational interventions to address this specific barrier. Choices B, C, and D are incorrect as they do not directly address the perception of risk among older adults. Older adults' awareness of HIV/AIDS, number of sex partners, or incidence of intravenous drug use are not the primary factors influencing their perception of HIV risk.

Correct Answer: D

Rationale: The correct answer is D because charting on the computer immediately after care is provided reduces the chances of forgetting important details and ensures accuracy. It also allows for real-time documentation, improving patient care. Choice A is incorrect as using the same password all the time poses a security risk. Choice B is incorrect as sharing passwords compromises confidentiality. Choice C is incorrect as printing out and reviewing notes at home does not address data entry errors on the computer system.
