Correct Answer: C

Rationale: The correct answer is C because in the humoral immune response, B cells are stimulated by T helper cells or macrophages to differentiate into plasma cells that produce antibodies or memory cells. This process involves the production of specific antibodies that target the foreign antigen. Choice A is incorrect because B cells do not phagocytize antigens; instead, they produce antibodies. Choice B is incorrect because T cells do not turn into plasma cells. It is the B cells that differentiate into plasma cells in the humoral immune response. Choice D is incorrect because T cells do not produce antibodies. T cells are involved in cell-mediated immunity, not the humoral immune response.

Correct Answer: A

Rationale: The correct answer is A: Inspecting for bleeding or cyanosis. During uterosigmoidostomy, the nurse's critical task is to monitor for any signs of bleeding or cyanosis, which are indicators of potential complications such as hemorrhage or impaired blood flow. This involves observing the surgical site for any abnormal bleeding and assessing the skin color for signs of inadequate oxygenation. Inspecting for symptoms of peritonitis (B) is not directly related to this surgical procedure. Assessing the client's allergy to iodine (C) is important but not a critical task during the procedure. Checking for signs of electrolyte losses (D) is important but not as critical as monitoring for immediate postoperative complications like bleeding or cyanosis.

Correct Answer: B

Rationale: Correct Answer: B (State Nurse Practice Acts) Rationale: State Nurse Practice Acts outline the legal scope of nursing practice, including standards for setting priorities, identifying client outcomes, and selecting evidence-based nursing interventions. These laws are specific to nursing practice, ensuring that nurses follow guidelines tailored to their profession. Nurses must adhere to these standards to provide safe and effective care. Summary of Incorrect Choices: A: Professional physicians' organizations - While physicians' organizations may provide guidelines for medical practice, they do not set standards specific to nursing practice. C: The Joint Commission - The Joint Commission focuses on accreditation for healthcare organizations, not setting standards for nursing practice. D: The Agency for Health Care Research and Quality - AHRQ conducts research and provides evidence-based information but does not establish standards for nursing practice.

Correct Answer: C

Rationale: The correct answer is C: 125 mL/h. To calculate the infusion rate per hour, we divide the total volume (1000 mL) by the total time in hours (8 hours). 1000 mL / 8 hours = 125 mL/h. This ensures a consistent and accurate infusion rate throughout the 8-hour period. Choice A (80 mL/h) is incorrect because it underestimates the infusion rate. Choice B (100 mL/h) is incorrect because it does not divide the total volume by the total time correctly. Choice D (150 mL/h) is incorrect because it overestimates the infusion rate.

Correct Answer: A

Rationale: The correct answer is A because it accurately describes the procedure of bronchoscopy. The nurse's explanation should focus on the insertion of a small tube through the nose or mouth into the bronchi to visualize the airways. This information helps the patient understand the basic process and what to expect during the procedure. Choice B is incorrect as bronchoscopy does not involve breathing a radioactive substance to show diseased areas in the lungs. Choice C is also incorrect as there is no requirement to drink a thick white liquid for bronchoscopy. Choice D is incorrect as dye injection is not a standard part of bronchoscopy, and asking about allergies to dye is irrelevant in this context.
