Immune System ATI Quizlet Questions
Question 1 of 5
What is a granuloma?
Correct Answer: B
Rationale: The correct answer is B: A collection of macrophages filled with antigens. Granulomas are tissue responses to chronic inflammation, where macrophages form a cluster to engulf and contain foreign substances like antigens. This leads to the formation of a granuloma, which can be seen in conditions like tuberculosis. Other choices are incorrect because: A) Antibodies are proteins produced by the immune system, not structures like granulomas; C) Mast cells are involved in allergic reactions and not typically associated with granulomas; D) An antibody-antigen complex is a different concept related to immune response but not specific to granulomas.
Question 2 of 5
What is the role of macrophages in granuloma formation?
Correct Answer: B
Rationale: The correct answer is B because macrophages play a crucial role in granuloma formation by engulfing antigens but failing to destroy them, leading to the formation of a cluster of immune cells to contain the persistent antigen. Macrophages present antigens to T cells, triggering an immune response. Other choices are incorrect as macrophages do not neutralize histamine, stimulate IgE production, or produce antibodies against antigens in the context of granuloma formation.
Question 3 of 5
A client is in the hospital and has received two doses of an angiotensin-converting enzyme for hypertension. When the nurse answers the client's call light, the client presents an appearance as shown below: What action by the nurse takes is most appropriate?
Correct Answer: C
Rationale: The correct action by the nurse is to ensure a patent airway while calling the Rapid Response Team (Choice C). This is because the client is showing signs of angioedema, a potential adverse reaction to angiotensin-converting enzyme (ACE) inhibitors. Angioedema can lead to airway compromise and respiratory distress, hence ensuring a patent airway is crucial. Additionally, calling the Rapid Response Team will allow for immediate medical intervention and monitoring of the client's condition. Choice A (Administer epinephrine) is incorrect as epinephrine is not the first-line treatment for angioedema associated with ACE inhibitors. Choice B (Apply oxygen) is not sufficient to address the potential airway compromise. Choice D (Reassure the client) is inappropriate as the client's condition requires immediate action to address the potential airway obstruction.
Question 4 of 5
B cells receive T cell help for antibody production in which specific lymph node structure
Correct Answer: E
Rationale: Failed to generate a rationale of 500+ characters after 3 retries using GPT-3.5.
Question 5 of 5
Which of the following is NOT an organ-specific autoimmune disease
Correct Answer: B
Rationale: The correct answer is B: Lupus. Lupus is a systemic autoimmune disease that can affect multiple organs and tissues throughout the body, rather than being specific to a single organ. Multiple sclerosis (A) is a neurological autoimmune disease affecting the central nervous system. Diabetes (C) is an autoimmune disease that affects the pancreas. Hashimoto's thyroiditis (D) is an autoimmune disease targeting the thyroid gland. Lupus does not specifically target a single organ, making it the correct choice.
