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. Which assessment finding would most likely indicate a complication of enteral tube feeding?

Correct answer: A

Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.

3. What is the most appropriate nursing action when a patient on anticoagulant therapy develops sudden, severe back pain?

Correct answer: C

Rationale: When a patient on anticoagulant therapy experiences sudden, severe back pain, the priority nursing action is to assess for signs of internal bleeding. Severe back pain in this context could be indicative of internal bleeding, such as a retroperitoneal bleed, which is a critical condition requiring immediate attention. Administering pain medication or applying a cold compress may mask or delay the identification of a potentially life-threatening situation. Repositioning the patient for comfort is not the priority when internal bleeding needs to be ruled out.

4. When a woman in early pregnancy is leaving the clinic, she blushes and asks the nurse if it is true that sex during pregnancy is bad for the baby. What is the best response for the nurse to give?

Correct answer: D

Rationale: Choice D is the best response as it reassures the patient that intercourse in a normal pregnancy will not harm the baby. It also shows empathy by acknowledging that many women experience changes in sexual desire during pregnancy. This response validates the patient's concerns and opens up a dialogue about her feelings. Choice A is incorrect as it lacks information about changes in sexual desire and oversimplifies the situation. Choice B is dismissive of the patient's concerns and does not provide adequate information. Choice C is not the best response as it suggests asking the doctor without offering immediate reassurance or addressing the patient's worries.

5. 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.
