PN Exit Exam 2023 Quizlet

Correct Answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

Correct Answer: B

Rationale: The correct answer is to assess the client's airway and respiratory status (Choice B). Difficulty swallowing after carotid endarterectomy could indicate swelling or nerve damage affecting swallowing, which may compromise the airway. Assessing the airway and respiratory status is crucial to ensure the client's ability to breathe. Administering an antiemetic (Choice A) is not the priority as the primary concern is airway patency. Elevating the head of the bed (Choice C) can help with swallowing difficulties but does not address the immediate risk to the airway. Encouraging the client to take small sips of water (Choice D) is contraindicated if there is a risk of compromised airway due to swallowing difficulties.

Correct Answer: B

Rationale: The primary purpose of using an abduction pillow after hip replacement surgery is to prevent hip dislocation. The abduction pillow keeps the legs separated, which reduces the risk of hip dislocation by preventing excessive internal rotation and adduction of the hip joint. Choices A, C, and D are incorrect as the main goal of using the abduction pillow is to maintain proper positioning and stability of the hip joint to prevent dislocation, rather than addressing blood clots, circulation, or pain relief.

Correct Answer: A

Rationale: The practical nurse should record the findings and report the symptoms to the charge nurse. These behaviors may indicate a serious underlying condition such as depression or physical illness. By reporting to the charge nurse, the client can receive appropriate assessment and intervention promptly. Choice B is incorrect as family visits may not address the root cause of the symptoms. Choice C is incorrect as it oversimplifies the situation and may not be effective in addressing the underlying issue. Choice D is incorrect because withholding medications without proper assessment and guidance can be harmful to the client's health.

Correct Answer: A

Rationale: The correct answer is A: Gallstones. Gallstones are the most common cause of acute pancreatitis as they obstruct the pancreatic duct, leading to inflammation. While alcohol abuse (Choice B) can also cause pancreatitis, gallstones are more prevalent. Hypertriglyceridemia (Choice C) is a less common cause of acute pancreatitis compared to gallstones. Infection (Choice D) is not a primary cause of acute pancreatitis; gallstones are the leading etiology.
