Rationale: Respect for persons is an ethical principle that emphasizes the autonomy and freedom of individuals to make their own decisions regarding participation in research studies. In the context of human subjects research, this principle requires that individuals have the right to choose whether or not to participate in a study, without any coercion or manipulation. The principle of respect for persons also includes the concept of informed consent, where individuals must be provided with all necessary information about the study in order to make an informed decision about participation. Overall, respecting the autonomy and choices of individuals is a fundamental aspect of ethical research conduct.

Correct Answer: D

Rationale: Record keeping involves several key steps such as structuring, securing, and storing information. However, easy disposal is not a step in record keeping. In fact, it is important to carefully consider the disposal of records in a secure and responsible manner to protect sensitive information and comply with relevant regulations. Proper disposal methods should be followed to ensure that records are not accessible to unauthorized individuals and that any sensitive information is properly destroyed to prevent misuse or breaches of privacy. Therefore, easy disposal is not a recommended practice in effective record keeping.

Correct Answer: B

Rationale: The nurse's best response when a patient expresses frustration with the healthcare system's inefficiencies is to listen actively to the patient's concerns, acknowledge the challenges they are facing, and offer support. It is important for the nurse to validate the patient's feelings and demonstrate empathy, rather than dismissing or ignoring their frustrations. By offering support and showing understanding, the nurse can help the patient feel heard and valued, which is an essential aspect of providing patient-centered care. This approach can also help to strengthen the nurse-patient relationship and build trust, ultimately leading to better outcomes for the patient's overall healthcare experience.

Correct Answer: C

Rationale: Naloxone, also known by the brand name Narcan, is used to reverse the effects of opioid overdose. Opioids can cause respiratory depression, sedation, and other signs of toxicity. Administering naloxone can quickly reverse these effects, restoring the patient's breathing and consciousness. This makes it the appropriate choice for reversing all signs of toxicity related to opioids. Digibind (Digoxin) is used to reverse toxicity from digoxin specifically. Atropine sulfate is used for bradycardia. Diazepam (Valium) is a benzodiazepine used for anxiety, seizures, and muscle relaxation, not for reversing toxicity.

Correct Answer: B

Rationale: The nurse can assure Sandy that her new joint will function almost as well as a normal joint if she performs her exercises faithfully because post-joint replacement surgery recovery often involves physical therapy and exercises aimed at restoring strength and mobility to the affected joint. By following the recommended exercise regimen and post-operative care instructions, Sandy can improve the function of her new joint and achieve a good level of mobility and functionality, similar to that of a normal joint. It is important for Sandy to be diligent and committed to her rehabilitation process to maximize the benefits of the joint replacement surgery.
