Correct Answer: C

Rationale: The nurse is acting as an advocate by ensuring the patient is fully informed before consenting to participate in the study. Advocacy in healthcare involves supporting and promoting the patient's rights, including the right to be fully informed about their care and treatment options. By advocating for the patient in this scenario, the nurse is prioritizing the patient's well-being and autonomy. Choices A, B, and D are incorrect. The nurse is not acting as a teacher, caregiver, or communicator specifically in this scenario, but rather advocating for the patient's right to informed consent.

Correct Answer: A

Rationale: If the informal discussion between the nurse and nurse manager does not resolve the issue regarding the physician's report on the nurse's performance, the nurse can submit a written appeal within 10 days, according to the health care facility policy. This 10-day timeframe ensures a prompt resolution of disputes and maintains clear communication channels within the healthcare setting. Choices B, C, and D are incorrect as they exceed the time limit allowed for the nurse to submit an appeal, which is specified to be 10 days.

Correct Answer: B

Rationale: The patient with a blood glucose level of 40 mg/dL (hypoglycemia) needs immediate attention as it is an emergency situation that requires prompt intervention to prevent adverse effects. Severe hypoglycemia can lead to serious complications, such as seizures or loss of consciousness. Therefore, the nurse should prioritize assessing and managing this patient first to prevent further deterioration. Choices A, C, and D do not present immediate life-threatening situations requiring urgent intervention like severe hypoglycemia does. A high hemoglobin A1C level, an abnormal oral glucose tolerance test result, and acute abdominal pain, while important, do not pose an immediate threat to the patient's life compared to severe hypoglycemia.

Correct Answer: B

Rationale: A critical pathway should be revised when variances in the patient's progress indicate a new trend or deviation from the expected course of treatment. This allows healthcare providers to adjust the pathway to ensure optimal patient care and outcomes. Changes in the critical pathway are not typically driven by its length or external factors like team member retirements or client discharges. Therefore, the correct answer is B. Choice A is incorrect because the length of the critical pathway alone does not determine the need for revision. Choices C and D are irrelevant to the patient's progress and treatment plan, making them incorrect.

Correct Answer: D

Rationale: The student nurse should not view the family member's record unless they are directly involved in providing care to maintain confidentiality. Accessing the record without a legitimate reason breaches patient confidentiality and violates ethical principles. Choice A is incorrect because being a nurse in the facility does not automatically grant access to a family member's record. Choice B is incorrect as it does not address the primary concern of direct involvement in care. Choice C is incorrect as family relationship alone does not justify accessing the medical record.
