Immune System Test Quizlet Questions
Question 1 of 5
A hybridoma:
Correct Answer: C
Rationale: Step-by-step rationale: 1. Hybridoma is a cell line formed by the fusion of a B cell (producing a specific antibody) and a myeloma cell. 2. Choice C is correct because hybridomas can be immortalized and cultured indefinitely. 3. Choice A is incorrect because hybridomas produce monoclonal antibodies, not polyclonal antibodies. 4. Choice B is incorrect because hybridomas are formed from a single B cell and a myeloma cell, not two antigen-activated B cells. 5. Choice D is incorrect as only option C accurately describes a hybridoma's characteristic of indefinite tissue culture survival.
Question 2 of 5
Select the correct number of statements that are true.
Correct Answer: A
Rationale: The correct answer is A. Statement 1 and 3 are true because selecting them would result in a correct answer. Statement 2 is incorrect as it claims that only 2 and 4 are correct, which contradicts the correct answer. Statement 4 is also incorrect as it claims that only 3 and 4 are correct, which is not consistent with the correct answer. The option "All of the above are correct" (D) is false because it includes statement 2, which is incorrect. Therefore, A is the correct choice because it accurately identifies the true statements.
Question 3 of 5
Which of the following is not a Covid-19 vaccine?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Nuvaxovid is not a known Covid-19 vaccine. 2. Covovax and Moderna are both established Covid-19 vaccines. 3. "None of the above" includes all listed options, so it is not the correct answer. 4. Therefore, the correct answer is A: Nuvaxovid, as it is not a recognized Covid-19 vaccine.
Question 4 of 5
The nurse is administering medications to a patient. Which medications should the nurse understand is being given to suppress C-reactive protein levels?
Correct Answer: A
Rationale: The correct answer is A: Aspirin and steroids. Aspirin is known to suppress C-reactive protein levels by inhibiting inflammatory pathways. Steroids also have anti-inflammatory properties that can lower CRP levels. Antibiotics, diuretics, epinephrine, antihistamines, antihypertensives, and antineoplastic agents do not have direct effects on CRP levels. It is important for the nurse to understand the mechanism of action of medications to ensure safe and effective administration.
Question 5 of 5
The nurse is reviewing the immune system with a patient newly diagnosed with an autoimmune disorder. What should the nurse explain as the purpose of antibodies?
Correct Answer: D
Rationale: The correct answer is D. Antibodies attach to antigens to label them for destruction. This is crucial in the immune response to identify and mark harmful substances for elimination. Choice A is incorrect because antibodies do not destroy antigens directly. Choice B is incorrect as antibodies are specific to particular antigens. Choice C is incorrect as blood type specificity is determined by different antigens, not antibodies.
