A nurse is caring for a client who has a terminal illness and is ventilator-dependent. The client is alert and oriented and wants to discontinue the ventilator. The nurse should be aware that continued treatment against the client's wishes is a violation of which ethical principle?

Correct Answer: B

Rationale: The correct answer is B) Autonomy. Autonomy refers to the individual's right to make decisions about their own healthcare, including the right to refuse treatment. In this scenario, the client, who is alert and oriented, has expressed their wish to discontinue the ventilator. Respecting the client's autonomy means honoring their decision, even if it may result in the client's death. Option A) Veracity refers to truth-telling, which is important in healthcare but is not directly related to the client's right to make decisions about their care in this situation. Option C) Fidelity pertains to the nurse's duty to be faithful and keep promises made to the client. While fidelity is important, in this case, the primary concern is respecting the client's autonomy. Option D) Justice relates to fairness and equal treatment of individuals. While justice is an important ethical principle in healthcare, it is not the primary consideration when a client is expressing their autonomy in making end-of-life decisions. In an educational context, this question highlights the significance of respecting patient autonomy and the ethical implications of decision-making in end-of-life care. It underscores the nurse's role in advocating for the patient's right to self-determination, even when the decisions may be difficult or result in a change in treatment that aligns with the patient's wishes. Understanding and applying ethical principles in such sensitive situations are crucial for providing patient-centered care.

Correct Answer: B

Rationale: The correct answer is B) Participants must be informed about the nature of the study. In research involving human participants, informed consent is a fundamental ethical principle. It is essential that participants are fully aware of the purpose, procedures, risks, benefits, and their rights before agreeing to participate. This ensures that individuals can make an autonomous and informed decision about their involvement. Option A is incorrect because deception is generally not acceptable in research involving human participants as it violates the principle of respect for persons and can harm participants' autonomy and well-being. Option C is incorrect because participants always have the right to withdraw from a study at any time, even after giving their initial consent. This is to protect the autonomy and well-being of participants. Option D is incorrect because disclosing participants' identities without their consent violates the principle of confidentiality and respect for individuals' privacy, which are crucial in research ethics. Educationally, understanding and applying ethical principles in research involving human participants is critical for ensuring the integrity, validity, and ethical conduct of research studies. Researchers and healthcare professionals must uphold these principles to protect the rights and well-being of participants and maintain the trust and credibility of the research community.

Correct Answer: D

Rationale: In the context of client safety and advocating for patients undergoing surgery, the correct answer is D) Determining the client's level of understanding about the procedure. This choice is crucial as it ensures that the patient has been adequately informed about the surgical procedure, its risks, benefits, and potential alternatives. Option A, Ensuring the charge nurse is available to witness the client's signature on the consent form, is important but does not address the nurse's direct role in informed consent. Option B, Explaining the risks involved with the procedure, is a part of the informed consent process, but it is the responsibility of the provider, not the nurse, to explain these details. Option C, Discussing alternate treatment options, is also essential but falls under the provider's responsibility. Educationally, understanding the importance of informed consent in healthcare is vital for nurses. It empowers patients to make autonomous decisions about their care and treatment. Nurses play a critical role in ensuring that patients are informed, understand their treatment options, and can provide consent based on a clear understanding of the procedure. This knowledge is foundational in upholding ethical principles and promoting patient safety and autonomy.

Correct Answer: B

Rationale: In the context of administering ophthalmic medications, asking the patient to look at the ceiling is the correct choice (Option B). This position helps to expose the conjunctival sac, making it easier to instill the medication without it rolling out. By looking up, the patient's gaze is directed away from the dropper, reducing the likelihood of blinking and increasing the chances of successful instillation. Option A, asking the patient to lie down, is incorrect because it may cause the medication to run out of the eye before it can be absorbed. Additionally, lying down may not provide the optimal angle for proper administration. In an educational setting, it is crucial to teach students the correct techniques for administering ophthalmic medications to ensure patient safety and efficacy of treatment. Understanding the rationale behind each step is important for students to grasp the rationale behind each step, reinforcing the importance of proper technique to achieve positive outcomes in patient care.

Correct Answer: A

Rationale: In the context of client safety, understanding and addressing sexual health issues is crucial. In the case of retarded ejaculation, which refers to delayed or inability to ejaculate, using a lubricant as an intervention (Option A) is the correct choice. A lubricant can help reduce friction and discomfort during sexual activity, potentially aiding in achieving ejaculation. It can enhance pleasure, improve comfort, and facilitate the process. It is a safe and non-invasive intervention that can be easily incorporated into sexual activities. Water (Option B) is not an appropriate intervention for retarded ejaculation. While staying hydrated is important for overall health, it does not directly address the issue of delayed ejaculation. In the absence of options C and D, it is imperative to focus on the key intervention for the specific condition being addressed. By selecting the correct option, educators can teach students the importance of using appropriate interventions to address sexual health concerns in a client-centered and effective manner.
