Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: The nurse's best response when a patient asks about alternative treatment options is to provide the patient with information about those options, including their benefits and risks. It is important for the nurse to support the patient in their exploration of different treatment approaches and empower them to make informed decisions about their care. Dismissing the question, ignoring it, or discouraging alternative treatments are not appropriate responses and may hinder the patient's ability to make choices that align with their values and preferences. Therefore, providing information and facilitating an open discussion about alternative treatments is the most appropriate approach for the patient's best interest.

Correct Answer: A

Rationale: Natural killer (NK) cells play a vital role in the innate immune response by identifying and eliminating virus-infected cells, as well as tumor cells, without the need for prior exposure or activation. NK cells are able to detect abnormal cells by recognizing changes in the cell surface molecules, such as downregulation of MHC class I molecules. Once activated, NK cells release cytotoxic granules containing perforin and granzyme, leading to the destruction of the target cell. This direct killing mechanism is crucial for controlling viral infections and preventing the development of tumors. NK cells do not produce antibodies (option B), present antigens to T cells (option C), or release cytokines to recruit other immune cells (option D) as their primary function in the immune response.

Correct Answer: C

Rationale: A profession is characterized by having a body of knowledge, a code of ethics, and engaging in research. However, being a member of a professional organization is not a defining characteristic of a profession. While many professionals may choose to join professional organizations for networking, support, and career advancement reasons, membership in such organizations is not universally required or exclusive to being considered a professional in a particular field. Hence, the presence or absence of professional organization membership does not determine the professional status of an individual.

Correct Answer: C

Rationale: Autonomy is the ethical principle that upholds an individual's right to make decisions about their own medical treatment, free from coercion or undue influence. In this scenario, the 70-year-old patient has voluntarily decided not to have the pacemaker inserted despite the physician's recommendation. The fact that the decision is respected by the family further highlights the importance of autonomy in this situation. Respecting the patient's right to make choices regarding their own healthcare, even if it goes against medical advice, demonstrates a commitment to autonomy as an ethical principle.

Correct Answer: D

Rationale: It is essential for the nurse to instruct the patient to "Report any unusual bleeding or bruising to your healthcare provider." Warfarin is a medication that works by decreasing the clotting ability of the blood. This can increase the risk of bleeding, so it is important for the patient to be vigilant for any signs of abnormal bleeding. Prompt reporting of any unusual bleeding or bruising allows healthcare providers to adjust the dosage of warfarin to maintain a balance between preventing blood clots and minimizing the risk of bleeding complications. This instruction emphasizes the importance of close monitoring and communication with healthcare providers while on warfarin therapy.
