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. The nurse is teaching a client with diabetes mellitus how to differentiate between hypoglycemia and ketoacidosis. What statement indicates to the nurse that the client has an understanding of this condition?

Correct answer: D

Rationale: The correct answer is D. Shakiness is a symptom of hypoglycemia, which is low blood sugar. Taking glucose can help raise blood sugar levels quickly in this situation. Fruity breath odor and excessive urination are signs of ketoacidosis, a complication of diabetes involving high levels of ketones in the blood. Blurred vision can be a symptom of high blood sugar, but it is not specific to hypoglycemia.

3. While conducting a mental status examination of a newly admitted male client, the PN notes that his head is lowered, and he shows no emotion or expression when speaking. Based on these observations, what documentation should the PN include?

Correct answer: C

Rationale: The correct answer is C: 'Flat affect.' Flat affect refers to a lack of emotional expression, which the PN observed in the client. This observation is significant as it can provide valuable information for the client's mental health assessment and subsequent care planning. Choice A, 'Impaired verbalization,' does not capture the lack of emotional expression seen in the client. Choice B, 'Depressed mood,' may not accurately reflect the observed behavior of the client. Choice D, 'Diminished LOC,' pertains to the level of consciousness, which was not indicated as being a concern in the scenario provided.

4. A registered nurse is preparing to hang the first bag of total parenteral nutrition (TPN) solution. The client has a central line, and this is the first bag he will receive. Which of the following is the most essential piece of equipment to obtain prior to hanging the bag?

Correct answer: C

Rationale: An electronic infusion pump is essential for administering TPN to ensure accurate delivery and avoid complications such as fluid overload or improper nutrient delivery. The pump helps regulate the flow rate precisely, which is crucial when infusing TPN. Monitoring the client's blood glucose is important but not immediately necessary before hanging the TPN bag. A noninvasive blood pressure monitor is not directly related to administering TPN and is not the most essential equipment needed for this procedure. Urine test strips are not required for administering TPN via a central line and are not essential equipment for this specific task.

5. What dietary considerations must the nurse keep in mind for a patient who is an Orthodox Jew?

Correct answer: B

Rationale: Orthodox Jews follow dietary laws (Kashrut) that prohibit mixing meat and dairy products in the same meal. This restriction is known as 'not mixing milk and meat.' Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because being an Orthodox Jew does not mean they can eat any food unless it is Yom Kippur, avoid meat on Ash Wednesday, or are necessarily vegetarian.
