Correct Answer: B

Rationale: To keep abreast with the latest trends in peri-operative nursing, Merle should employ a combination of attending training and seminars, performing researches, and pursuing graduate studies. Attending training and seminars will expose Merle to new information, techniques, and best practices in peri-operative nursing. Performing researches will help Merle stay updated with current developments and evidence-based practices in the field. Pursuing graduate studies will provide Merle with advanced knowledge and skills, allowing for a deeper understanding of peri-operative nursing concepts and practices. By incorporating all of these strategies, Merle can ensure that he remains knowledgeable and competent in his role as a peri-operative nurse.

Correct Answer: B

Rationale: Providing the patient with privacy and assurance of confidentiality is essential to create a safe and trusting environment for open communication. By assuring the patient that their information will be kept confidential, the nurse can help alleviate the patient's fears and encourage them to feel more comfortable discussing their personal health issues. Dismissing the patient's concerns (option A), ignoring their reluctance (option C), or telling them that their embarrassment is unnecessary (option D) are not effective approaches and may further hinder open communication. It is crucial for the nurse to create a supportive and nonjudgmental atmosphere to build trust with the patient and facilitate honest discussions about their health concerns.

Correct Answer: D

Rationale: When giving health teaching to the mother on how to manage the patient at home, emphasizing the need for emotional support is crucial. Taking care of a patient at home can be emotionally taxing, and the mother needs to be aware of the importance of providing emotional support to the patient. This can greatly impact the patient's overall well-being and recovery. By emphasizing the need for emotional support, the mother can create a conducive and supportive environment for the patient to heal physically, mentally, and emotionally. It also helps foster a sense of connection and positivity, which is beneficial for the patient's overall health outcomes.

Correct Answer: B

Rationale: T cell exhaustion is a state of T cell dysfunction that arises during chronic viral infections or cancer. In the case of a chronic viral infection, the persistent exposure to viral antigens leads to continuous stimulation of CD8+ cytotoxic T cells. Over time, this sustained stimulation can lead to T cell exhaustion, characterized by the upregulation of inhibitory receptors, impaired effector functions, and reduced proliferative capacity. As a result, despite the elevated levels of CD8+ T cells in the blood, their function may be compromised, ultimately impacting the immune response against the viral infection. In contrast, activation-induced cell death (AICD) may contribute to T cell loss during chronic infections but would not explain the persistently elevated CD8+ T cell levels. Thymic involution refers to the age-related decline in thymus function, which is not directly related to the observed increase in CD8+ T cells. Antigenic

Correct Answer: D

Rationale: A family history of breast cancer is a known risk factor for the development of ovarian cancer. Individuals with a close relative (such as a mother, sister, or daughter) who has had breast cancer have a higher risk of developing ovarian cancer. This increased risk is due to shared genetic factors that can predispose individuals to both breast and ovarian cancers. Therefore, having a family history of breast cancer is an important risk factor to consider in the assessment of ovarian cancer risk.
