Immune System ATI Quizlet Questions
Question 1 of 5
What receptor is targeted in Grave's disease, a Type V hypersensitivity reaction?
Correct Answer: B
Rationale: The correct answer is B: Thyroid-stimulating hormone (TSH) receptor. In Grave's disease, autoantibodies bind to and activate the TSH receptor on thyroid cells, leading to hyperthyroidism. This is a Type II hypersensitivity reaction. Insulin receptor (A) is not involved in Grave's disease. Complement receptor (C) is not the target in this condition. CD4 receptor (D) is primarily involved in T cell activation, not in Grave's disease.
Question 2 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.

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 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.
Question 5 of 5
Which of the following statements is NOT true
Correct Answer: B
Rationale: The correct answer is B because vaccines using attenuated HIV virus are not in a "phase II" clinical trial. Attenuated virus vaccines are risky due to potential reversion to virulence. A: True, Sub-Saharan Africa has the highest HIV prevalence. C: CD4+ counts decline during clinical latency. D: Viral RNA titer increases in the final stages.
