Questions About the Immune System Questions
Question 1 of 5
What is a side effect of xanthine oxidase inhibitors? (Select one that does not apply)
Correct Answer: D
Rationale: The correct answer is D: Retinal damage. Xanthine oxidase inhibitors like allopurinol can lead to retinal damage, causing vision problems. This is due to the drug's potential to accumulate in the retina. Bone marrow suppression, nausea, and vomiting are not common side effects of xanthine oxidase inhibitors, making them incorrect choices.
Question 2 of 5
One of the following conditions is associated with anemia due to decreased erythropoietin response:
Correct Answer: C
Rationale: The correct answer is C: Bone marrow infiltration. When the bone marrow is infiltrated by tumors or other abnormal cells, it impairs the production and release of erythropoietin, leading to decreased erythropoietin response and subsequent anemia. Hypothyroidism (choice A) does not directly affect erythropoietin levels. Myelofibrosis (choice B) is associated with increased erythropoietin levels due to ineffective erythropoiesis. Thalassemia (choice D) is a genetic disorder affecting hemoglobin production, but it does not directly impact erythropoietin response.
Question 3 of 5
One of the following is a primary lymphoid tissue:
Correct Answer: A
Rationale: The correct answer is A: Thymus. The thymus is considered a primary lymphoid tissue because it is where T cells mature and differentiate. It plays a crucial role in the development of the immune system. The other choices, B: Spleen, C: Lymph node, and D: Liver, are considered secondary lymphoid tissues where immune responses take place but not where lymphocytes mature.
Question 4 of 5
The nurse is conducting a teaching session with a client on their diagnosis of pemphigus. Which statement by the client indicates that the client understands the diagnosis?
Correct Answer: C
Rationale: The correct answer is C because it accurately states that pemphigus is an autoimmune disease that causes blistering of the skin. This demonstrates an understanding of the underlying cause of the condition. Option A is incorrect as pemphigus presents with blistering, not tiny red vesicles. Option B is incorrect as pemphigus is not caused by a virus. Option D is incorrect as the description provided does not match the characteristic presentation of pemphigus.
Question 5 of 5
The nurse is performing an assessment on a client who has been diagnosed with an allergy to latex. In determining the client's risk factors, the nurse should question the client about an allergy to which food item?
Correct Answer: D
Rationale: The correct answer is D: Bananas. Latex allergy is associated with cross-reactivity to certain fruits like bananas due to similar proteins. Therefore, questioning the client about a banana allergy is crucial to assess the risk of allergic reactions. Eggs (A), milk (B), and yogurt (C) are not typically associated with latex allergies, making them less relevant in this context.
