PN Exit Exam 2023 Quizlet

1. Which type of cell is responsible for producing antibodies in the immune system?

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.

2. An older male client with Alzheimer's disease is admitted to an extended care facility. Which intervention should the PN include in the client's nursing care plan?

Correct answer: A

Rationale: The correct intervention for a client with Alzheimer's disease in an extended care facility is to plan to have the same nursing staff provide care whenever possible. Consistency in caregivers helps reduce confusion and anxiety in clients with Alzheimer’s disease, promoting a stable and supportive environment for the client. Choice B is incorrect as it focuses on activities rather than the consistency of caregivers. Choice C is incorrect as it suggests isolating the client, which can lead to increased confusion and distress. Choice D is incorrect as introducing the client to new people immediately can be overwhelming and may exacerbate their symptoms.

3. An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the PN document as evidence that the amount of insulin is inadequate?

Correct answer: C

Rationale: The correct answer is C. High evening glucose levels indicate that the morning dose of NPH insulin may be insufficient to control blood sugar throughout the day. Choice A is incorrect as cold and numb feet are more indicative of a circulation issue rather than an insulin inadequacy. Choice B suggests a wound infection rather than inadequate insulin. Choice D, nausea in the morning, may be due to other causes and does not necessarily indicate inadequate insulin dosage.

4. Which of the following best describes the role of insulin in the body?

Correct answer: B

Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.

5. After a hip replacement surgery, a client is instructed to use an abduction pillow while in bed. What is the primary purpose of this device?

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.
