PN Exit Exam 2023 Quizlet

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: D

Rationale: The best response reassures the patient by explaining the process of verifying and marking the correct eye, a safety measure to prevent wrong-site surgery, directly addressing the patient's concern. Choice A is close but implies the ID bracelet alone determines the correct eye, missing the verification process. Choice B talks about confirmation but lacks details about marking the correct eye. Choice C mentions the surgeon's record but does not specify the direct verification and marking process, unlike Choice D.

Correct Answer: C

Rationale: Having the client sit down in the hallway is the first action the nurse should implement. This is crucial to prevent further strain on the heart and to provide a safer environment for assessment and potential emergency intervention. Administering sublingual nitroglycerin (Choice A) may be appropriate later but should not precede ensuring the client's immediate safety. Assisting the client back to the room (Choice B) may not be advisable if the client is experiencing chest tightness and shortness of breath. Obtaining a 12-lead electrocardiogram (Choice D) is important but would not be the initial action to address the client's immediate symptoms.

Correct Answer: B

Rationale: Lung cancer is the leading cause of cancer-related deaths in women, surpassing even breast cancer. While breast cancer is more common, it is often detected early enough for effective treatment. Lung cancer, on the other hand, tends to be diagnosed at later stages, leading to higher mortality rates. Brain cancer and colon and rectal cancer are not the leading causes of cancer-related deaths in women, making them incorrect choices.

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.
